Patent GB-1181938-A (GB)
Title: Data-Processing Machines
Inventor: MUTZ G
IPC: B41J11/46
Filed: 1968-04-17
Abstract: 1,181,938. Statistical apparatus. KIENZLE APPARATE G.m.b.H. 17 April, 1968 [22 April, 1967], No. 18092/68. Heading G4M. An account sheet is transported to position the next vacant line in printer 104, 105 under the control of a counter which is preset to the complement of the line number and is counted up by pulses from a photo-cell LS3 detecting line-denoting marks on the sheet. The next vacant line number is recorded, together with other data on a magnetic strip on the sheet sensed by read head MK. The line number is up-dated as the sheet is ejected after printing or after keyboard initiated line-shift by one or more lines in the forward direction. When a sheet is placed on table 57, card levers and an associated photo-cell cause energization of solenoid KK to engage pressure rollers 50, 51 and start the drive so that the sheet enters the machine. Deflector 85a normally allows sheets to pass unhindered, but when in the operative position, directs sheets being ejected into receptacle 86, and prevents any other sheets from entering. Photocell LS2 detects the presence of a sheet to enable read head MK. Deflector 106 can be operated to direct sheets emerging from the reading station into receptacle 107 while at the same time preventing ejection of a sheet from the printing station. Drive to the feed rollers is through forward and reverse clutches, an electromagnetic brake being applied when neither clutch is energized. Reference has been directed by the Comptroller to Specification, 818,078.

Patent GB-531083-A (GB)
Title: Improvements in or relating to the collection and insertion into envelopes of pluralities of sheets, pamphlets, or the like
IPC: B43M3/04
Filed: 1939-06-22
Abstract: 531,083. Inserting sheets into envelopes. ROSE, A. G. and ROSE. BROS. (GAINSBOROUGH), Ltd. June 22, 1939, No. 18153. [Class 94 (i)] A machine for collecting bundles of sheets or " inserts " and inserting them in envelopes comprises means for withdrawing a batch of inserts one from each of a series of magazines and depositing them in superposed relationship to form a bundle on a conveyer, a feeler for detecting a failure to withdraw an insert from a magazine and for causing the rejection of the deficient bundle, and means for removing each bundle from the conveyer and passing it through a guiding-device into an envelope. The inserts are stored in a series of magazines 6 arranged adjacent to an intermittently moving conveyer 7 provided with pushers 11. A pusher stops momentarily adjacent to each magazine, and in this position an insert 17 is withdrawn from each magazine simultaneously and deposited in front of the pusher, by an oscillating suction nozzle 22. A gripper 34, which reciprocates along an horizontal guide 38, grips the insert and draws it to its correct position above the conveyer where a positioning member 39 descends and presses it down on to platform members 12, 13 between guides 18, 19. As each pusher 11 carries the completed bundle away from the last magazine, a member 61 pushes the bundle off the members 12, 13 through a mouthpiece 62 into an open envelope 63. The envelopes are stored in a magazine 102, Fig. 1, and are withdrawn by a suction nozzle and deposited by reciprocating grippers in a conveyer platform 101 arranged transversely to the conveyer 7. The envelope is carried along the conveyer by reciprocating pushers 110 to the mouthpiece 62, and during this movement, the flap of the envelope passes below a guide 137 which deflects it below the mouthpiece 62. A suction nozzle 138 lifts the upper portion of the envelope to open the mouth, whereupon the mouthpiece is moved until it just enters the envelope. The bundle is then pushed through the mouthpiece into the envelope by the member 61. A feeler device, consisting of rollers 151, 152, Fig. 3, closes on each insert as it leaves its magazine 6. If an insert is not withdrawn, the rollers allow contact points to touch and complete the electric circuit of a device that rejects the deficient bundle. A similar device is used in association with the envelope magazine.

Title: Improvements in and relating to controlling valve devices for fluid pressure systems
IPC: F16K31/42
Filed: 1930-06-13
Abstract: 356,809. Fluid-actuated valves. LE CLAIR, L. J., BRACKENBURY, A. G., and WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London. June 13, 1930, No. 18169. [Class 135.] A main slide or other valve 2, which establishes communication between a source of fluid pressure or vacuum and the operating cylinder for raising or lowering the pantagraph current collector in vacuum - braked electric rolling stock supplied by overhead electric conductors, is actuated by one of two vacuum. operated diaphragms 3, 7, the valve 2 remaining in the operated position independently of the fluid pressure and being returned by the other diaphragm. The diaphragms carry headed stems 10, 11 fitting loosely and with lost motion between lugs 12, 13 on the slide valve 2 which is held at either end of its stroke by a spring 24 engaging end inclines 25, 26 on a housing member. The diaphragm chambers 4, 8 may each be put into communication through a chamber 5 and inlet 30 with the source of vacuum by means of pilot valves 19, 27 respectively, operated by electromagnets 16, 17 under control of the driver. Atmospheric pressure exists in the slide valve chest 1 and the pantagraph cylinder, or other operated device, is connected at 31 to a chamber 6. In operation, to raise the pantagraph the solenoid 16 is energized thereby withdrawing the diaphragm 3 and moving the slide valve 2 to the right to put the pantagraph cylinder into communication with the vacuum source through chamber 6, port 18, a valve recess 20 and a restricted opening 21. The solenoid valve is then released, the chamber 4 venting to the valve chest 1 through a groove 23 in the diaphragm stem so that the diaphragm returns to its normal position leaving the slide valve 2 detained by the spring 24. The solenoid 17 is operated to bring the valve back to the position shown where the cylinder communicates with the atmosphere through a port 18<1>, for lowering the pantagraph. The pantagraph is raised more slowly than it is lowered by virtue of the restricted port 21. Manual operation is provided by a hand-lever 34 having depending lugs 37 engaging between the valve lugs 12, 13. After operating the valve, the lever is returned to the mid position by springs 39.

Title: Improvements in gunner's seats used in aircraft gun turrets
IPC: B64D7/02
Filed: 1943-11-06
Abstract: 579,670. Aircraft gun turrets. RICE, E. A. B., ROSE, A. G., CURTIS, S., NICHOLLS, K. H., and ROSE BROS. (GAINSBOROUGH), Ltd. Nov. 6, 1943, No. 18474. [Class 92 (i)] A gunner's seat for an aircraft gun turret has the gunner's parachute attached to it in such a manner as to form part of the seat, while at the same time being readily detachable. In the construction shown, the parachute 22 is connected to the back 19 of the gunner's seat by a safety strap 21 which is secured to one side of the seat by rivets and to the other side by press studs 25. The back 19 is pivoted at 23 to a bracket 24 on the rotatable platform 13 of the turret and is fitted with pivoted stays 27 connected by a rod which normally engage in notches 31 of a pair of spaced base-plates 32. The back may be folded back to a substantially horizontal position by lifting the rod out of the notches and letting it slide along tracks 34 between the base-plates and upper guide-plates 33. The seat 18 is mounted on a pillar 37 slidably mounted in a tubular support 38 attached to an extension of bracket 24. A spring-controlled hand lever 42 is pivoted to the pillar and carries on its arm 44 a pin 46 which protrudes through a slot in one side of the support and into one of a series of holes 48 in the other side. Thus, the seat, which is urged upwardly by a compression spring 41 as shown, may be adjusted to the required position. Specification 577,904 is referred to.
Patent GB-820501-A (GB)
Title: A winding machine
Inventor: ROTTER ERHARD FRANZ
IPC: B65H18/10
Filed: 1956-06-14
Abstract: 820,501. Expanding pulley gearing. POENSGEN G.m.b.H., GEB. June 14, 1956, No. 18498/56. Class 80 (2). [Also in Groups XVI and XXXV] An apparatus for winding strip material from one drum on to another has driving means comprising two driven members coupled to the shafts of the winding drums having infinitely variable contact circles, a driving member acting on the respective contact circles of the driven member, and an adjustable control means by which the sum of the squares of the respective contact circles diameters of the two driven members is maintained constant during winding in response to positive and negative deviations of the algebraic sum of the circumferential speeds of the winding drums from zero, thereby maintaining substantially constant tension in the material being wound. As shown, web material unwound from a shaft 32 is wound on a shaft 31. The shafts 31, 32 carry pairs of axially slidable conical pulleys 3, 3<SP>1</SP> and 4, 4<SP>1</SP> respectively keyed to these shafts. The pulleys are driven by a belt 7 driven at a constant predetermined linear speed through a pulley 8 by a variable speed motor, not shown. The distance apart of the pulleys of each pair determines the speeds of the shafts 31, 32 by adjustment of their effective contact circles with the belt 7. Variations in web tension, detected by a roller 13 on a spring-urged lever 15, causes corresponding variations of a sliding contact 19 of a rheostat 61. The rheostat is in circuit with three resistances 62, 63 and 64 connected to an amplifier 44. When the contact is in preset position the resistances 61, 62 balance the resistances 63, 64. Variations in web tension cause movement of the contact 19 thereby upsetting the balance whereupon current flows from the amplifier 44 to the motor 43. The motor 43 rotates a shaft carrying worms 41, 42 in the direction appropriate to the particular variation in web tension, i.e. an increase or decrease, thus rotating toothed discs 39, 40 carrying pins 35, 36. The pins 35, 36 engage slots in arms 33, 34, connected to the pulleys 3, 3<SP>1</SP> and 4, 4<SP>1</SP> which upon rotation of the discs 34, 40 adjust the distance apart of the pulleys. The discs 39 and 40 rotate in opposite directions, such that the pulleys 3 and 3<SP>1</SP> are moved apart when the pulleys 4 and 4<SP>1</SP> are moved together and vice versa, thereby increasing the speed of one shaft 31 or 32 and decreasing the speed of the other to maintain constant the tension and linear speed of the web being wound. In a modification (Fig. 3, not shown), the distance apart of pulleys is adjusted by arms engaging threaded shafts driven at appropriate speeds when it is required to adjust the speeds of the winding and unwinding drums.

Title: Sensing circuits
IPC: H01L33/00
Filed: 1975-05-02
Abstract: 1510320 Transistor amplifier SONY CORP 2 May 1975 [10 May 1974] 18511/75 Heading H3T A sensing circuit comprises a bipolar transistor 10 with an extra gate region 4G, of the same conductivity type as the base, embedded in the emitter region within the minority carrier diffusion distance from the emitter-base junction (Fig. 3, not shown). The conductivity types of the regions may be reversed. A varying resistance sensing element 15 is connected between gate and emitter, forming with the internal base-gate resistance a potential divider controlling by alteration of resistance 15 the gate potential over the range from base to emitter potentials. This in turn swings the operating mode from high gain-high collector current when the gate is at base potential to low gain-low collector current when at emitter potential (Fig. 7, not shown). By variation of the setting of base current by bias control 20, the condition for maximum sensitivity of collector current to resistance 15 change may be selected. The sensing device may respond, e.g. to temperature, magnetic field or light. A trigger circuit to switch at a selected level of the sensed parameter, or with interposed differentiating circuit to switch within a selected range, may be connected to output terminal 22.

Title: Process and device for the extraction of liquid
IPC: A23L19/15
Filed: 1959-06-01
Abstract: 881,969. Filters ; presses for separating liquids from solids; filter media. RITTER, J. June 1, 1959 [June 2, 1958; April 28, 1959], No. 18523/59; Class 46. [Also in Group XIII] In Fig. 1, material 4 to be filtered and pressed is conveyed at 2 to a moving band 3 of foamed rubber or foamed plastic or other porous and resilient medium which is drawn over a perforate sheet 5 between rotating rollers 8, 9. Prior to compression therebetween, filtration takes place through the band into a container 6. The band and material are compressed, whereupon liquid is squeezed out of band 3 and flows into container 6. On re-expansion of band 3 beyond the nip of the rollers the residue 4a of the material is pressed into contact with roller 8 and removed therefrom in particulate form by a brush roller 11. A second treatment of this material, like the first, may follow. In Fig. 3, concentric perforate cages 21 to 21<SP>11</SP> are provided each having a band of foam material 22 within it and attached, or not, to it. Here, it is the filtrate which is successively treated by bands and pairs of rollers after the first. In Fig. 5, only some of the unfiltered material is fed at 102 on the band 111; the remainder is fed at 113 on to a second band 106 moving counterclockwise. First filtrate from band 106 falls into a tank 117, communicating with main filtrate tank 113. Filtrate from above band 106 in the region between pre-pressing rollers 114, 115 and main rollers 104, 105 is discharged at 116 into tank 113. The main rollers are closer together than the pre-pressing rollers. In Fig. 6 the uppermost and lowermost bands are driven clockwise and the middle band counter-clockwise. Material introduced at A is thrice prepressed before reaching the main pressing rollers 124, 119<SP>1</SP> in the first run, the residue passing at B to the second run. Filtrates are collected in troughs 129 to 129<SP>11</SP>. Other modifications. In Fig. 4 (not shown), the second band 106 covers roller 104 only, parts 114, 116 and 117 being dispensed with. In this case the residue sticks to bands 106, 111 beyond the nip of the rollers and is removed therefrom by two other non-contacting rollers respectively. Each of the two last-mentioned rollers has associated with it a brush roller to remove the residue in particulate form. In another form, endless bands are dispensed with, the (stationary) filter medium being disposed on a circular disc over which a taper roller moves along with the material under treatment. Alternatively the filter medium may move. In all cases the pressing elements may be heated.

Filed: 1946-06-20
Abstract: 628,877. Knitting- machines. BENTLEY ENGINEERING CO., Ltd., and KENT, A. W. June 20, 1946, No. 18562. [Class 74 (ii)] [Also in Group IX] A cylinder and dial machine having a number of yarn feeding positions is provided with a yarn feeding device for each position and toothed change-speed gearing for each device driven from a common gear. As described, each device is driven from the drive for the dial which rotates a pinion 8 carrying a series of crown wheels 9 .... 12. A pinion 6 is slidably keyed on a shaft 5, supporting one of the furnishing members 1, and engages any one of the gear wheels 9 . . . 12 to effect a change in the speed of rotation of the shaft. The furnishing members 1, 2 may be intermeshing tapered gear wheels, one of which is mounted on a bracket 15 adapted to be swung to move the wheel out of mesh with the other. A swing- ing damper 28, provided with an eye 3 and a dropper 4, is mounted above the wheels 1, 2 and a second dropper 25 is pivoted below the wheels. The second dropper engages a strut 27 maintaining a lever 20 pivoted on the shaft 21 of the wheel 2 in a raised position. A ratchet wheel 23 is mounted to rotate with the wheel 1. The yarn is guided by the eye 3 between the wheels 1, 2 to the eye of the second dropper 25 from which it passes to the first dropper 4 and to the machine. As the tension of the yarn varies the dropper 4 is moved accordingly and rotates the damper 28 to vary the position of the yarn between the wheels. If a yarn breaks between the wheels and the machine, the dropper 25 drops to release strut 27, permitting the lever 20 to engage the rotating ratchet 23 so that the wheels are forced apart to release the yarn and to allow a stop motion engageable with the yarn above the wheels to operate and stop the machine.
