Title: Machine for producing axially open rivets and double pointed tacks
IPC: B21K1/58
Filed: 1951-07-11
Abstract: 691,890. Punching. LAFLEUR, A. G. July 11, 1951 [July 12, 1950], No. 16433/51. Class 83 (iv). [Also in Group XXX] In a machine for making axially open rivets and double - pointed tacks, starting from a solid rivet having a cylindrical body and a projecting head, the feeding of the solid rivet and the ejection of the finished article are performed downwardly and vertically and the punch reciprocates horizontally in an axial plane of the rivet while this is held with its axis vertical. Solid rivets are fed from a rotary table 1 down a guideway 2, from which they are transferred in succession to a lower guideway 4 by aT-section slider 3, Fig. 9, reciprocated by an arm 8 to which it is connected by a spring 9. The lower guideway comprises a fixed plate 6 and a plate 7 fixed to and movable with the slider 3, such that as the slider moves to pick up a rivet from the guideway 2 the adjacent edges of the plates 6, 7 are in contact. Should a rivet jam in the guideway 4, the plate 7 and slider 3 are prevented from moving forward to pick up the next rivet from the guideway 2, and the reciprocating movement of the arm 8 is taken up in the spring 9. The end of the guideway, Fig. 12, is shaped to present the rivet with its axis vertical to spring-loaded jaws 11, through which it is then pushed by a plunger 18 into holding dies 34, 53, the plunger being vertically reciprocated from a cam groove 28, Fig. 15, through a double-arm lever 25, 26 and toggle joint 22, the cam groove being designed to cause the plunger to maintain pressure on the rivet during punching. A pin 24 in the system breaks in the event of jamming. The fixed die 34, Fig. 16, is adjustably positioned by a screw 33 and held by a wedge 35 in a carrier 31 adjustably positioned by a screw 32. The movable die 53 is secured by a wedge 38 to a carrier 37 reciprocated from a cam on a shaft 58 through a lever 39 and an adjustable link 44, 45. The punch 36 on a slider 48 is reciprocated horizontally from an eccentric 49 on the shaft 58 through an adjustable connection 56. An extractor arm 54 on the carrier 37 releases any finished work-piece held in the die 34, as the dies open after punching to enable the punch to be retracted without jamming, and a stationary extractor 52 releases work-pieces which adhere to the movable die 53.

Title: Improvements in or relating to thermionic valve circuits
IPC: G01R23/09
Filed: 1944-09-01
Abstract: 585,478. Valve amplifying and pulse counting circuits. STANDARD TELEPHONES & CABLES, Ltd., and WESTON, J. D. Sept. 1, 1944, No. 16723. [Class 40 (v)] [Also in Group XXXVI] In a circuit employing a valve 1 having at least two grids, a gas-filled valve 2 is arranged between the cathode resistance R3 and the screen resistance R5, the valves being chosen so that R5+r=Á R3, where r is the effective resistance of the gas-filled valve and Á is the amplification factor of the valve. A waveform, the frequency of which is to be measured or a train of pulses to be counted is applied to the grid of valve 11, Fig. 2. The voltage from the anode is fed over a coupling condenser, to a high resistance 20 across which a bias voltage is developed due to resistances R5, 19 connected to the H.T. supply. The grid of valve 1 is normally tied to earth by rectifier 18 conducting, but upon the signal from valve 11 exceeding the bias voltage across resistance 20, the rectifier ceases to conduct. The signal from valve 11 is arranged to be of a sufficiently large amplitude to cut off valve 1, whereupon the anode. potential rises to the supply voltage. Condenser 21 charges through the bridge rectifier 22 to give an indication on meter 23. When the waveform reverses, or the pulse ceases, and valve 1 conducts, condenser 21 discharges through the opposite half of the r,ectifier 22. Assuming condenser 21 charges and discharges substantially completely to the two potential levels, the indications of meter 23 are proportional to the frequency of the signal applied to valve 11. In a modification, Fig. 3, a voltage is developed across resistances 28, 29 and applied to valve 31 to decrease the current giving an indication on meter 23. Resistances 32, 34 and condensers 33, 36 provide smoothing, condenser 30 acting as a blocking condenser. Meter 23 may be in the cathode circuit of valve 31. Specification 510,941 is referred to.

Title: Improvements relating to automatic weighing machines
Inventor: HEAUME FRANCIS HERBERT DU
IPC: G01G19/22
Filed: 1951-07-18
Abstract: 706,931. Weighing-apparatus. SIMON, Ltd., H. July 7, 1952 [July 18, 1951], No. 17025/51. Class 143 In a battery of automatic weighing machines for proportionately blending cereal grain or like material, the discharge gate switches are connected in series with a current supply, when all the batches are made up to the correct weight, through one of two alternative circuit paths containing path-setting change-over switches each switched to its other position by the opening of the discharge gate of a weigher, the arrangement being such that the batches are simultaneously discharged and only if previously all the batch discharge gates had actually opened. The whole mechanism therefore stops in the event of any failure of any one of the discharge gates to open. As shown, Fig. 7, switches b are closed on completion of each weighment (by the descent of a weigh hopper under gravity releasing a catch permitting a fixed lever 1a, Fig. 4, to fall and the mercury switch b thereon to close) so that circuits are completed from a source of current through the switches b, one position of double-pole change-over switches 20 and discharge gate latch release electromagnets a. A parallel connected coil 21 actuates an electromagnetic counter counting the number of discharge operations. On each discharge gate opening the levers 1a are again raised to re-open the switches b and through levers 8, 9 and a spring- controlled pawl and ratchet 10, 12 to rotate by one step a hill and valley wheel 14 which alternately raises and lowers a counterweight lever 18 carrying two differently inclined mercury switches c, d forming the alternately closed path setting switches 20. The weigh hopper 6a, Fig. 2, is connected through linkage with a pivoted. feedgate frame 6 which cuts off the feed on a weighment being completed and raises a catch 5a pivoted to the framework so that a formerly retained lever 3.pivoted at 3b to the framework is allowed to fall and with it the lever 1a so that the mercury switch b on it closes. The electromagnets are then energized so that the discharge gate latch is released and the discharge gate 4 opens. A roller 4a on a lever 4b connected to the discharge door consequently engages a roller 3a on the lever 3 raising it and the lever 1a so that the switch 6 and the electromagnets are deenergized and a catch 5 is allowed to fall so that its nose contacts the bottom roller 3a of the lever 3, maintaining it and the lever 1a in raised position when the discharge door again closes. On the discharge being completed the weigh hopper 6a rises and the catch 5a falls to retain the levers 3, 1a in raised position. In a modification the switches b are in series with the switches 20 but not located between opposite legs of the switches.
