Title: Improvements in and relating to a contact pin crimping machine
IPC: H01R4/20
Filed: 1951-07-23
Abstract: 692,289. Jointing by stamping. BRITISH THOMSON-HOUSTON CO., Ltd. July 23, 1951 [Aug. 22, 1950], No. 17402/51. Class 83 (iv). Tubular contact-pins 4, Fig. 2, are crimped on to the lead wires 6 of electric lamps &c. in an automatic machine by a pair of punches 16, 17 which move through slots 14, 15 in a pair of dies 10, 11 with opposed semi-circular grooves 12, 13 for holding and confining the pins. The die 10, Fig. 3, is mounted on the machine base 20 and the die 11 is slidable along guides 23, 24 mounted in the die 10, and actuated to engage the pins by a pneumatic ram 30 through a pair of levers 40 pivoted on each side of the base 20. The levers 40 have slots 42 at the upper end engaging pins 44 on the die 11 and are oscillated by pins 38 on the cross-head 35 of the ram, which engage in lost-motion slots 39 in the levers 40. The crimping punches 16, 17 are carried by slides 18, 19 movable by toggles 53, 54 which are actuated by the ram 30 through bell-cranks 49, 50 having slots 47 engaged by transverse pins 37 carried in lost-motion slots 46 in the cross-head 35. In operation, the ram 30 is controlled through automatic solenoid-actuated means which is switched on by the depression of a plunger (not shown), mounted under the base 20 and engaged by the pins 4 of a lamp 1 when inserted between the dies 10, 11. Initial movement of the ram 30 causes the die 11 to engage the pins 4 and continued movement causes the dies 16, 17 to crimp the pins 4 over the lead wires. A trip switch 69 engaged by an arm 71 on the cross-head 35 sets up the return-stroke of the ram. The arrangement of the switches ensures that further actuation of the ram is prevented until a further lamp base is placed in position. Punches.-The punches 16, 17 have blunt wedge-shaped ends which are slightly inclined at an angle of approximately 6 degrees to the vertical so that the lead wires tend to flow upward through the bores of the pins to avoid straining the glass seal. The punch 16 further has a slot 116 to cause pocketing of the material of the pin so that the lead wire becomes positively locked in the pin. The method may be used for crimping pins of the type disclosed in Specification 692,290, [Group XXXVI].

Abstract: 1,003,894. Doffing and drafting carded webs. CHICOPEE MANUFACTURING CORPORATION. June 1,1962, No. 17437/65. Divided out of 1,003,893. Heading D1N. During removal from a doffing cylinder fibres are simultaneously drafted by the action of an endless belt and an associated pressure roller or other member which grip the fibres on the doffing cylinder and transport them at a higher linear speed than that of the doffing cylinder. The belt 30 extends over a bar 22 which is adjustable angularly and for clearance relative to the doffing cylinder 12, the clearance preferably lying between 0. 005 to 0. 150 inch. A nip roll 32 with a diameter from about 0. 75 inch to 3 inches rests upon the belt and is also adjustable relative to the doffing cylinder 12 with preferred clearances of from about 0. 007 to 0. 040 inch. The action of the belt is to press against the fibres on the doffing cylinder to compact the web which is then led into the nip between the belt and the roller 32. Linear speed ratios between the belt 30 and the cylinder 12 may lie between 1.1 to 1 up to 10 to 1 or higher, with optimum results at about 3 to 1. The materials from which the nip roll is made may be metal, leather, rubber, plastic, fabric or film and the fibres treated may include, as well as textile fibres, short papermaking fibres, such as woodpulp and wood fibres, cotton linters, mineral fibres such as asbestos, glass, rockwood or other fibres down to about 1/ 1  inch or less. The gripping zone between the belt 30 and the roller 32 or an alternative member should be as long as the longest fibre being doffed. An alternative to the roller 32 is a second belt that extends over an arcuate shoe (Fig. 6, not shown). Specification 946,694 is referred to.

Title: Control system for a balancing hoist
IPC: B66D3/18
Filed: 1971-05-27
Abstract: 1345725 Hoists GARDNER-DENVER CO 27 May 1971 [18 Nov 1970] 17536/71 Heading B8B [Also in Division F2] A control system for a fluid operated balancing hoist 10 having a pressure fluid operated motor including an expansible chamber 36 drivably connected to a load rope drum 26, comprises a pressure regulator 84 between the fluid supply source and the chamber 36 and including means 85, 160 for sensing the pressure in the chamber and adjusting the regulator 84 to maintain a pressure value, and locking means 90, 172 operable to lock the sensing means at a predetermined pressure setting corresponding to a balanced condition of the load connected to the hoist. To raise a load 32, lever 120 on a depending controller 76 is depressed to operate valves causing air to be supplied to the chamber 36 to wind up the rope 28, an adjustable pressure sensing valve in this supply line restricting the fluid flow to the chamber if a low pressure (hence low or no load on the hoist) exists, or unrestricting the flow if a load is sensed. If the load is to be balanced, the lever 120 is further depressed to operate valves causing the locking means 90, 172 to be fluid pressure released against spring bias so that the sensing means 160, 85 may be displaceable by pressure from the chamber 36 acting on the end face 166 of the sensing means. This displacement is opposed by springs 86 and 150 supporting therebetween a valve spool 136. When the hoisting distance is reached, the lever 120 is released whereupon the sensor 160, 85 is locked by the means 90, 172 in a position corresponding to the prevailing pressure in the chamber 36. The chamber pressure is now communicated to the end 148 of the valve spool 136, this line being vented during the balancing and the spool 136 is moved into its balance position shown, where the port 130 leading to the chamber 36 is isolated from both ports 128, 132 which may be coupled to pressure and exhaust respectively. Thereafter, any manual raising or lowering of the load changes the pressure in the hoist chamber 36 whereupon the spool 136 moves to appropriately connect the port 130 to air supply or exhaust ports 128, 132 to again balance the load in its new position. Further valves are provided on the controller 76 for a restricted venting of the chamber 36 to permit gravitational lowering of the load and for an unrestricted venting for rapid pay out of slack cable from the hoist.

Title: Sequence controller
IPC: G05B19/06
Filed: 1973-01-09
Abstract: 1365862 Valves ISIS TECHNICAL FINISHES Ltd 9 Jan 1973 [14 Jan 1972 1 Nov 1972] 17543/73 and 50280/72 Divided out of 1363922 Heading F2V [Also in Divisions H2 and G3] In a system controlling the sequential operation of motors M1, M2, which may control rotary plug valves, closure of switch CS, e.g. in response to pressure, energizes relay R3 which in turn energizes solenoid L1 in latching relay LR causing the latter to make a circuit via Y through relay R1, thereby causing a motor M controlling sequence switches CS1-4 to rotate. The motor M moves switch S to its opposite position to energize relay R2 which in turn energizes a reset solenoid L2 in latching relay LR. Relay R1 is accordingly reset but motor M continues to rotate until it sets switch S, at which point the motor windings are shortcircuited to produce regenerative braking. Initial rotation of the motor M will have opened switch CS1 and final rotation operates switch CS2 to energize timer relay T which eventually completes a circuit through L1 to cause a further operation of motor M which reopens CS2 and operates CS3 to complete a circuit through relays R5, R7 to starter relay R4 of motor M1 which operates switch S1 to energize relay R5 causing the latter to break the circuit R4 and complete a circuit to L1 to initiate a further operation of motor M. Motor M1 meanwhile continues to run, following reset of relay R4, until it resets switch S1 to produce braking as in the case of motor M. The latter resets CS3 and operates CS4 to produce operation of motor M2 in the manner described with reference to M1. Once R7 has been energized to break the circuit to R6 (which is the equivalent of R4) and to complete a circuit to L1, the motor M undergoes its final operation of the cycle and resets CS4 prior to reclosing CS1, leaving the system ready for the next operation of CS. In a modified system, the switches CS1-4 are replaced by rotary switches driven by a unidirectional A.C. motor, each valve again being controlled by a D.C. motor as above except that the starter and feedback relays are not embodied in the motorvalve unit but connected therewith via the rotary switches. In this latter system, there are two start button switches one of which initiates sequential operation of selected valves under control of corresponding rotary switches whereas the other initiates sequential operation of the remaining valves under control of the remaining rotary switches.

Abstract: 860,125. Automatic character reading. INTERNATIONAL COMPUTERS & TABULATORS Ltd. May 3,1957 [June 7, 1956], No. 17613/56. Class 106 (1). [Also in Group XVI] Marks are formed on a record card by a printing member which prints a humanly legible character adapted to be sensed to generate representative signals in a predetermined code, the signals being produced by the sensing of a " start " portion and other horizontallyarranged portions of the character. The characters are shown in the Figure, each having a bottom start portion, a space in lines X and Y and two further transverse portions the spacing of which relative to the start portion is the characteristic feature. Where the two further portions occupy adjacent positions, as in numerals 0, 1, 4 and 7, the are formed as a single portion of double thickness. The start mark may not be part of the character but may be instead a separate bar printed underneath. The area sensed is indicated on each character by parallel dotted lines. Where the characters are in ordinary ink, sensing may be by photo-electric means. Alternatively the characters may be printed in a magnetic ink, a radio-active ink or a fluorescent ink. The printing member may be a single type slug used as in a typewriter or different characters may be formed on a printing bar or wheel. Alternatively the printing member may be embodied in a sheet-like printing surface, e.g. for use as an address plate.

Abstract: 218,487. Harwood, J., and Cutts, H. July 7, 1923. Cases, watch; winding- apparatus; setting - apparatus.-In watches wound automatically by a weight oscillated by the movement of the wearer overwinding is prevented by frictionally connecting the weight A to a plate D pivoted on the same spindle and carrying a spring-pressed pawl G which engages a ratchet wheel I operating the winding train. A counterpawl J is pivoted on the spindle K. The weight is provided with spring buffers A<1>. The frictional engagement between the weight and plate D is maintained by a spring E adjustably secured by screws F. The hands are set bv a contrate wheel on a rotary bezel which drives a pinion K<1> and spindle L. The spindle L has a projection P which first engages the set-hands gear M, O by working on a cam M<1> of the crown wheel and finally operates the gear by engaging the projections Q. The crown wheel is normally held disengaged by a spring-pressed pivoted lever S engaging the radial end R<1> of a spring R which surrounds the crown wheel and by which the crown wheel is held stationary during the operation of the cam by the projection P. To allow the hand-setting gear to be disengaged the bezel is rotated backwardly after operation through an angle corresponding to 5 minutes. Marks may be provided at, say, 10-minute intervals on the bezel to indicate the required backward rotation. The lever S may have a coloured disc adapted to show through an aperture in the dial when the hand-setting gear is disengaged.

IPC: C25C1/14
Filed: 1922-06-27
Abstract: 204,387. John, A. S. June 27, 1922. Tin, removing and depositing; barrel apparatus; electrolytes, heating.-Scrap tin-plate is detinned by electrolysis in an alkaline bath, then washing, and finally electrolysis in an acid bath. The scrap is contained in perforated steel drums 1 which may be lifted from one tank to another when required; they are supported by bearings 3 so as to be partially immersed in the electrolyte and are rotated through worm gearing by shafts 15. The bearings 3 may be of graphite and insulated from the tank to make the positive electric connection with the shafts 2, or they may be of insulating material such as non- hygroscopic wood and separate spring contacts provided. The cathodes are sheets of electrolytic copper or steel suspended by wood or' other insulating brackets from the tank and are curved to conform with the drums and spaced not less than 4 inches from them. The electrolyte is heated by steam pipes protected from sediment by a tray. The alkaline bath contains 6 to 9 per cent cf sodium hydroxide, and 1 per cent of stannic chloride at starting. The acid bath contains 1 to 2 per cent of commercial hydrochloric acid. The electrolysis is carried out at a temperature of 150‹ F. with a pressure of 6 volts and a current of 800 to 1000 amps. The tin is scraped off the cathodes, pressed into blocks, and smelted in a crucible. Reference has been directed by the Comptroller to Specifications 15402/99 and 122,025.

Title: Improvements in electric repeaters for telephony
IPC: H04B1/10
Filed: 1920-06-29
Abstract: 145,578. Western Electric Co., (Assignees of Crisson, G.). May 20, 1919, [Convention date]. Thermionic relays and repeaters. - In order to prevent cross-talk between lines connected to thermionic repeaters having their filaments heated by a common battery, the output circuit of each valve is connected at its filament end to a point intermediate in potential between the potentials at the ends of that filament. Fig. 3 shows one arrangement. The input circuits are coupled inductively to the gridfilament circuits of the valves 1, 2, 3 and the output circuits are coupled by transformers 4<a>, 5<a>, 6<a> to the plate-filament circuits. The plate current is supplied by a common battery B through choke coils 11, 11<a> individual to each valve. The filaments 1<a>, 2<a>, 3<a> are connected in series to a battery A through a choke coil 7 which may be short-circuited by a switch 8. The invention consists in connecting the plate of each valve, preferably through a condenser 12 and transformer primary 5<a>, to a point 15 intermediate the ends of the filament. A connexion may also be made from this intermediate point through a condenser 18 to the junction of the choke coils 11, 11<a>. The point 15 should be slightly nearer the low-potential terminal 9 than the other terminal 9<a>. Instead of making the connexions to an intermediate point of the filament, a resistance 48, Fig. 5, may be shunted across it and connexion made to a suitable point therein. In another form, two unequal capacities are connected in series across the filament terminals 9, 9<a>, and the connexions made to a point between them. The larger capacity is connected to the more negative terminal 9. Another alternative comprises an inductance 20, Fig. 6, connected across the filament terminals in series with blocking condensers 22, 23, the point 15<a> being chosen nearer the negative filament terminal 9. The connecting-points 15, 15a are chosen so that the voice currents passing from plate to filament do not produce potential differences at the filament terminals 9, 9<a> and therefore do not set up voice currents in the filament circuit which would affect the remaining filaments and set up crosstalk. The condenser shank 18 provides a path for leakage voice currents which would otherwise produce cross-talk by passing from plate to filament through coils 11, 11<a>, battery B, ground and filament circuit.

Title: A yarn propelling mechanism and apparatus and method for measuring yarn friction at varying linear speeds and tensions
IPC: G01N19/02
Filed: 1963-05-06
Abstract: 1,006,754. Yarn-feeding apparatus. MONSANTO CO. May 6, 1963 [May 22,1962], No. 17805/63. Heading D1D. [Also in Division G1] In a yarn friction measuring device yarn 12 is fed by tapered rollers 14,16,18 over a guide pulley 52, a weighted tension pulley 44 and passed over friction surface 46 as shown in Fig. 1, or in a modification, in place of the friction surface 46, the yarn is adjustably twisted by a pulley 66, as in Fig. 2. The yarn subsequently passes over a weighted strain gauge pulley 48. The weights 60, 62 are chosen so that the measurement on the strain gauge is twice the difference between tensions T 1  and T 2  of the yarn before and after engagement respectively with the friction surface. This value is equal to twice the friction force and is recorded by means 64. The yarn is then passed over further guide pulleys 52 and over rollers 16, 14, at a position axially spaced from the feed path, and giving an increased circumference of the rollers to take up stretch. Adjustable guides 36 are provided to position the yarn on the rollers at desired axially spaced paths.
