Title: Improvements in or relating to machines for making metal filters
IPC: B21F27/18
Filed: 1940-04-05
Abstract: 537,063. Making filters ; grids. MOTOR IMPROVEMENTS, Inc. April 5, 1940, No. 6214. Convention date, Oct. 11, 1939. [Classes 83 (ii) and 83 (iv)] Coiling : die-rolling. A machine for making metal filters of the kind consisting of a cylindrical grill-like frame containing a metal ribbon helically coiled with its turns spaced apart by projections, comprises a stationary cylindrical block in which is journalled a a shaft round which rotates and slides a head carrying the frame, and means for guiding the ribbon within the frame so that its outer edge is in contact with the inner surface of the frame. The frame F is secured by bolts 55 to the reduced end of a head 33, which is rotatably mounted in a frame 45 provided with driving pulleys 46, 47 and longitudinally movable on shafts 30 and 14. Wire W is passed between conical rolls 22, 21 which flatten it into ribbon form and impart a curvature about an axis perpendicular to the wide faces as described in Specification 385,755. The roll 21 also has indentations 23 so as to produce spacing projections on one side of the ribbon. The ribbon is then conducted through a guide tube 53 and is passed through a slot 41 in a recessed stationary cylindrical block 16 and then the end is secured by a screw 54 in a slot 33a in the head 33. The shaft 14 carries a hub 34 on which a pair of spring-pressed semi-circular blocks 37 are mounted so as to engage the inner edge of the ribbon, and press the outer edge against the frame F, the shaft being driven preferably at a slightly greater speed than the head 33. The shaft 14 is driven at constant speed by a belt 26 from a shaft 13 and transmission 27 from a shaft 28 which is belt driven from the main shaft 17. The head 33 is driven by a belt 48 from the shaft 30 which is keyed to the pulley 46 and is driven through the infinitely variable transmission 27, which may be adjusted by a lever 32 to ensure that the ribbon is coiled at the same rate as it is delivered from the rolls 22,21. The building up of the helix causes movement to the right of the head 33 and frame 45, such motion being opposed by weights. When the frame F is filled with the helix the machine is stopped, both ends of the helix are soldered &c. to the frame and the ribbon cut. The ribbon is disconnected from the head by loosening the set screw 54 and the bolts 55 are then loosened, and after disengaging the bracket 44 the head 33 is moved out of the frame and then out of alignment with the head 16 so that the finished filter may be removed.

Title: Combination tabulating and card punching machine
Inventor: HOOL HUNTER EARICK
IPC: G06C11/08
Filed: 1958-02-26
Abstract: 821,214. Statistical apparatus. ROYAL. McBEE CORPORATION. Feb. 26,1958, No. 6300/58. Class 106 (1). [Also in Group VIII] A tabulating-machine of the kind having a keyboard and reciprocating racks 29, Fig. 3, for controlling the wheels of an accumulator mechanism, also comprises a card-sensing mechanism consisting of a reciprocating carriage 41 having a slot 53 for the card 54, a plurality of sensing-pins 57-60 which are displaced or not when the carriage is reciprocated according to the punched data in the card, and calibrated spacers connected to the sensing-pins adapted through a coupling slider 85 to control the movement of the racks 29 operating the accumulator wheels in accordance with the data sensed, and a card punch consisting of a second reciprocating carriage 109 with a slot 115 for a blank card, a plurality of punches adapted to perforate the card when the carriage is reciprocated and projections 137, 138 on the slider 85 to activate the punches in accordance with the data sensed to punch the same data into the blank. The two carriages are operated successively on rotation of a main shaft of the machine by pairs of cams on the shaft, one pair connected to each carriage by follower links on each side of the machine. Sensing.-The spacers are mounted on four arms 64-67 pivotally connected to the sensing pins. They have sizes proportional to values 1, 2, 4 and 7, these being the significance of the four punch positions in each column. A column with value " 5 " punched in it has holes in the first and third position. The 1 and 4 spacers are therefore retracted so that when slider 85 is raised as shown in Fig. 4 it can rise 5 units before being stopped by the abutment between lug 101 and the remaining spacers. This movement transmitted to rack 29 by lever 95 sets the associated accumulator wheel forward by five digits and sets printing mechanism to print " five " on the recording tape. The card has twelve columns, ten being for different denominations, one for a carry over and the last for special control purposes, e.g. for making subtractive, non-add entries. Punching.-The carriage 109 reciprocates to bring the card carried against twelve columns of four punches 123. If a hole is to be punched the corresponding punch is prevented from sliding back by an actuator which is governed by abutments 137, 138 on the slider 85. Coded projections 136 on the actuators engage the abutments according to the position of the sliders to punch the appropriate holes in the card. On taking a total the sliders 85 are actuated from the accumulator to punch the value accumulated into the card. The sliders may likewise be set by using the keyboard.

Title: Apparatus and method for automatic application of adhesive tape
IPC: B65B51/06
Filed: 1960-02-23
Abstract: 867,698. Applying adhesive tape. CELLOPHANE INVESTMENT CO. Ltd. Feb. 23, 1960 [Nov. 27, 1959], No. 6345/60. Class 73. An apparatus (and a method) for applying adhesive tape to three sides of rectangular boxes advances the boxes intermittently spaced apart a distance sufficient to provide a length of tape to apply to two of the sides, applies tape to one side, grips the tape between the boxes at two points and cuts it between them, and applies the cut ends to a further side of each of two boxes. The boxes, 1 to 13, are advanced along on the rails 73, 74 of a track 70, 71, 72 by dogs 20, 21, 22, on a bar 17 which reciprocates lengthwise and vertically. Tape 58 is joined to a tear-strip 62 at 59 and is applied to one side of a box 2 by a roller 65. Each of the two grippers 87, 89 comprises a flap carrier 102 pivoted on a pin 104 on a support 100. A flap 106 with suction holes 112 grips the intervening run of the tape whilst a cam operated knife 80 cuts it. The flaps 106 then swing out across the track and apply the cut ends of the tape to the front of a box 3 and rear of a box 4 simultaneously, slight movement of the flap relative to the carrier keeping the tape in tension. The knife 80 does not cut the tape exactly centrally and also slits it along a short distance on either side of the rip-strip at the longer end, so that the tab tape end projects out on the fourth side of the box after the short adhesive margins on either side of it have been pressed down by a roller 135. The taped boxes are diverted by pushers 138, 139 past rollers 136, 137 which perfect application of the tape. The gripper 5, bar 17 and knife 80 operate from cams on a single shaft driven by an electric motor which drives the pushers 138, 139 (Fig. 1 not shown) synchronously with them.

IPC: G01L3/16
Filed: 1941-05-17
Abstract: 548,368. Dynamometers. ASHWORTH, ROSS & CO., Ltd., and MILLS, R. A. May 17, 1941, No. 6372. [Class 106 (ii)] A force transmission mechanism comprises a pair of lever systems arranged in separate housings and means external to the housings for interconnecting the lever systems so as to admit of transmission of the load to one or other of the load indicating devices associated with each housing. The torque arm of the dynamometer is provided with a plate 1 to which is bolted a yoke 2 having knife edges 2a, 2b co-operating with bearing links 3, 7 and a lever 4 supported on a base bracket 5. The link 7 has a knife edge connection 8a with an intermediate lever 8 supported on a pedestal 9 and communicating through a bearing link 10 and a lever 11 with a connecting rod 14 of a load indicating device (not shown). The lever 11 is supported on a bearing block 12 that is adjustable by means of a cam 15 and manipulative lever 16. In the position shown the lever 11 is free to transmit motion to the indicating device. To prevent transmission the lever 16 is rotated to lower the lever 11 so as to place stops 11c thereon on to angle brackets 17. In accordance with the present invention an intermediate lever 8 is extended through the side of the housing 6 and is formed with a jaw extension 8c adapted to be connected through a bearing link 18 with the intermediate lever 19 of a similar lever system in the housing 21. With the link 18 in the position shown and the lever 11 lowered the torque applied to the plate 1 will be transmitted to the indicating device associated with the connecting rod 22. In the alternative position of the link 18 when it engages the knife edges 19a, 8e the intermediate lever 19 serves to transmit movement from the torque arm in the housing 21 to the connecting rod 14 of the other indicating device.

Title: Improvements relating to gas blast circuit breakers
Inventor: YOUNG AUSTIN FREDERICK BRABANT
IPC: H01H33/70
Filed: 1952-03-13
Abstract: 718,985. Gas-blast switches. REYROLLE & CO., Ltd., A. March 13, 1953 [March 13, 1952] No. 6548/52. Class 38(5) A gas-blast circuit-breaker having synchronizing means for ensuring initiation of the arc at a predetermined instant in relation to a current zero, is of the type in which the arc is transferred from the moving contact to a stationary arcing electrode before quenching so that " current chopping " in the case of small magnetizing currents is avoided. The circuit-breaker has a blast passage C with a nozzle C<SP>1</SP> serving as an arcing electrode, a fixed contact D and a laterally moving contact E. In operation, a polarized highspeed primary relay K connects secondary relays L, M alternately on successive half cycles to a tripping line A<SP>1</SP>. When the line A<SP>1</SP> is energized by a tripping signal from a source A, the secondary relay L, or M, which is selected at the moment the signal occurs, is energized and is held in over contacts L<SP>1</SP> or M<SP>1</SP>. At the same time a solenoid B is energized to open a blast valve and admit compressed gas to the circuit-breaker. At the end of the half cycle in which the tripping signal is initiated, the relay K changes over its contacts K<SP>1</SP>, K<SP>2</SP> to energize the other secondary relay. L or M and a circuit is then completed through contacts L<SP>2</SP>, M<SP>2</SP> to a delay relay N. When the relay N closes its contacts, a solenoid J is energized to move a detent H and unlock a lever G. The compressed gas in the passage C is now able to move a piston F and open the contacts D, E. The time of delay of the relay N would be so adjusted that the total time elapsing from the first current zero after the initiation of the tripping signal to the instant at which the are has travelled to the nozzle C\ is equal to one cycle. Should the synchronizing control fail to unlock the piston F, a piston R, supplied through a constriction R<SP>2</SP>, is able to turn the detent H through a lost motion connection R<SP>3</SP>.

Abstract: 698,205. Regulating fluid Now. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 4, 1952 [March 20, 1951], No. 6614/51. Class 135 Apparatus for regulating the flow of a gas, e.g. hydrogen fluoride, generated from the liquid or solid state consists of a container 2 for the liquid or solid substance, a water bath 3 with electric heating elements 1 and a thermostat 4, and a conduit 8 leading from the container to an orifice 10 which operates in a " choked " condition, i.e. the gas is at sonic velocity at the throat of the orifice. As the flow rate through such an orifice is independent of conditions downstream of the orifice it can be determined solely by upstream conditions, i.e. by the setting of the thermostat, and the use of a calibration chart. In the case of hydrogen fluoride, the orifice plate 9 and the conduits 8, 12, 22 are of nickel and are lagged, and as the flow rate through the orifice is independent of the temperature of the gas only if the latter is completely dissociated to the monomolecular state, an electric heating element 17 is wound round the conduit 8 to superheat the gas to ensure complete dissociation. A copper block 19 soldered to the conduit 12 upstream of the orifice is drilled to receive a thermometer 20 for indicating that the gas is at a temperature at which it is completely dissociated. A filter 14 is fitted upstream of the orifice.

Abstract: 1,183,701. Converting. PLESSEY CO. Ltd. 28 April, 1967 [15 Feb., 1966], No. 6620/66. Heading H2F. [Also in Division G3] A power converter comprises: a pair of input terminals arranged to have an alternating current signal Vac applied thereto; a filter including an inductor L1 connected in series between the input and output thereof, one end of the inductor being connected to one of said input terminals; a further pair of terminals having a capacitor Cr connected thereacross; and switching means comprising solid state switching devices Q1, Q2 each having a switching signal applied to a control electrode thereof, for selectively applying the filtered signal afforded by the other end of the inductor to the further pair of terminals, the magnitude and polarity of the signal appearing across the further pair of terminals being dependent upon the phase difference between said alternating current signal and the switching signal applied to the switching means to effect switching thereof. In one embodiment, Fig. 15, the switching signals for the devices Q1, Q2 are derived from an oscillator formed by saturable transformer T2 and transistors Q3, Q4. In order to regulate the D.C. power developed across capacitor Cr, the voltage and current are sensed by resistors R2, R3 which apply signals to comparator circuits Q6, Q7 -and Q8, Q10 which provides a control signal to vary the frequency of the oscillator. A further control dependent on the A.C. is also applied to transistors Q1, Q2 via transformer T3. The converter circuit may be modified by employing two pair of opposite conductivity transistors, Fig. 10 (not shown) or to use thyristors Figs. 13, 16, 17 (not shown). In the last mentioned circuit the firing point control is provided by a magnetic amplifier. Ripple is reduced by means of an amplifier, Fig. 20 (not shown) which senses the ripple component present at the D.C. part and provides a corresponding antiphase signal which is connected in series with the reservoir capacitor.
