Title: Improvements relating to electromagnetic switching relays
IPC: H01H50/40
Filed: 1957-08-22
Abstract: 818,577. Electromagnetic relays. UHER, E. Aug. 22, 1957 [Sept. 1, 1956 ; June 25, 1957], No. 26566/57. Class 38 (5). An electromagnetic relay particularly for the control of a car lighting dynamo and similar to that of Specification 704,412, [Group XXXV], has a magnetic shunt 33, 34 (Figs. 3 to 5) between the pole 9 and armature 35 and arranged so that a part 34 thereof, of a ferromagnetic alloy having a temperature-dependent permeability, lies outside the relay case 30, 32 so as to be subject to the external temperature, in order that the relay may operate at lower current and voltage values at higher ambients. The armature 35 has a contact 15 normally engaging a fixed contact 14 under the bias of the armature mounting spring 12. The combined effect of the voltage and current coils 6, 7 moves the armature so that first the contacts 14, 15 part and later the contact 15 engages a second fixed contact 16. The members 33, 34 pass through a rubber muff 37 in the relay cap 32 and are arranged with a constant gap z between the armature part 36 and part 34 in all armature positions, alternative arrangements being shown in Figs. 3 and 5. In Fig. 11 the part 34 of ferromagnetic alloy is fixed between two iron members 33, 40, the latter having a narrow neck y to saturate and limit the by-pass effect of the magnetic shunt path at higher operating values. The end of the member 40 is bent at 41 to be parallel with an upturned end 42 of the armature 35 and arranged so that the gap z is approximately constant as the armature is moved angularly. The end 42 may be parallel to the pole 9 with no upturned end to the armature (Fig. 14, not shown) but in this case the gap z is variable, or the end 42 may be perpendicular to the pole and co-operate with an armature end constructed similar to 36 in Fig. 5 (Fig. 15, not shown).

Abstract: 460,673. Valve amplifying circuits. BRIDGEWATER, T. H. Sept. 26, 1935, No. 26678. [Class 40 (v)] A tetrode valve amplifier for television signals &c. has an impedance connected in its screengrid circuit so designed in relation to the valve and its operating voltages that the output or anode voltage is substantially in phase with the input voltage. The input voltage 6 is applied between the control grid and the cathode, and the output is taken from terminals 11, 4 between anode and cathode. The screen-grid is connected to the high tension positive terminal 3 by a resistance 12, and to the cathode through a large condenser 13 in series with resistances 14, 15. The screen-grid voltage swings in phase opposition to the control-grid voltage, and predominates in its effect on the anode current, causing the anode voltage to vary in phase with the control grid. By reducing the resistance 15 or by shorting it by. a switch 16, the valve operates in the normal manner as a screen-grid amplifier. The amplifier may thus be used for giving " positive " or " negative " pictures in a television system.

Title: Improvements in transfer mechanism for cigar making machines
IPC: A24C3/00
Filed: 1931-09-24
Abstract: 380,944. Cigar-making machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(International Cigar Machinery Co. ; 5520, 2nd Avenue, Brooklyn, New York, U.S.A.) Sept. 24, 1931, No. 26696. [Class 130.] Cigar-bunches and cigars 'are transferred, between mould, wrapping, and re-rolling mechanisms, by a swinging arm movable between the mechanisms which arm carries (1) two grippers in adjacent relation, (2) a gripper shifting device which moves the grippers in unison upon the swinging arm to bring one or other of them into an operative position and (3) a gripper opening and closing device operable upon that gripper which has been brought into the operative position. The grippers are formed by a finger 52, fixed on a shaft 51 carried by a swinging arm 49, and by two movable fingers 53, 54 loosely mounted on the shaft 51. A spring 55 normally forces the fingers 53, 54 towards the finger 52, and each of them is separable from the finger 52 by a gripper opening and closing device formed as a cam finger 57 which is moved between rollers 56 carried on extensions of the fingers. The cam finger 57 is carried by an oscillating arm 63 on the swinging arm 49. The gripper shifting device is formed by an oscillating arm on the swinging arm, having a cam slot 58 which guides a crank pin 59 carried by the shaft 50. In operation, starting from the position shown in full lines in Fig. 1, the fingers 52, 54 are gripping a moulded bunch which has been lifted out of the mould 12 by a finger 14. The arm 49 is then raised vertically, and the oscillating arm which carries the cam slot 58 engages a stop 62<1> and swings the fingers into the position shown in dotted lines in Fig. 1 where the fingers 52, 53 are in the operative position. The arm 49 then swings towards the re-rolling mechanism, Fig. 4, and is lowered until a projection 66<1> engages the lever 63 and forces the cam finger 57 between the fingers 52, 53 to release the cigar carried from the wrapping mechanism, Fig. 6. The arm 49 is then raised vertically and is swung towards the wrapping mechanism, and during this movement a projection 69 on it engages a pivoted plate 71 and positions a stop 73 beneath the lever 63. The wrapping rollers 148, 148a separate and a rest 76 carries a cigar towards the transfer mechanism. As the arm 49 descends the stop 73 engages the lever 63 to withdraw the finger 57 and causes the fingers 52, 53 to grip a wrapped cigar. The arm 49 is raised vertically and the cam 58 swung by a fixed stop (not shown) to bring the fingers 52, 54 carrying the moulded bunch into an operative position. As the arm 49 rises it disengages the pivoted plate 71 which is moved by a spring to position a stop 75 beneath the lever 63 so that when the arm 49 is lowered a second time over the wrapping mechanism the finger 57 opens the fingers 52, 54 and releases the bunch. The arm 49 is then raised and swung back to the moulding mechanism where it is lowered and the finger 57 removed from the fingers 52, 54 by a stop 60a.

Title: Improvements relating to last slice or end piece holders as used in connection with slicing machines
IPC: B26D7/01
Filed: 1929-09-03
Abstract: 337,518. Berkel & Parnall's Slicing Machine Manufacturing Co., Ltd., and Thomas, H. Sept. 3, 1929. Cutting slices in succession. - A last slice holder for a slicing-machine has a substance positioning face which is adjustable relatively to the gripping elements so that the thickness of the last slice can be regulated. As shown in Fig. 1, the face plate 10 is movable from the full line position, in which a thick last slice is left, to the dotted line position in which a thin last slice results. The plate 10 is carried by pins 20 slidable in the frame of the holder. Springs 22 tend to move the plate 10 towards the shafts 15 of the gripping prongs which are arranged and operated in known manner. The movement of the plate is effected by a handle 31 on a shaft 24 carrying eccentrics 25 which press against levers 26 interconnected with similar levers, all of which gear against the back of the plate 10 and move it in opposition to the springs 22. To prevent the springs 22 from pushing the mechanism back when the handle 31 is released, the eccentrics 25 engage recesses in the levers 26 which are thereby locked, or alternatively, the eccentrics and the parts of the levers 26 engaged thereby are toothed and interengaged so that the plate 10 is locked in any adjusted position. In a modification, the face plate 10 and a similar back cover plate are flanged and placed together to form a substantially enclosed casing which is slidable on a stationary supporting frame interposed between the face and back plates. The sliding of the casing, and consequently the adjustment of the face plate, is effected by the rotation of a shaft journaled in the frame and having eccentric members which engage members secured to the slidable casing. The prong carrying shafts are journaled in the fixed frame and are operated by a pivoted handle carrying a toothed segment which meshes with a pinion on one of the shafts carrying intermeshing pinions. The back plate of the casing is secured by a pivoted bolt and is easily removalble. In a variation of this construction, the sliding of the casing is effected by eccentrics on a vertical shaft journaled in the fixed frame, engaging and operating toggle levers pivoted between the front and back plates. The front and back plates are removable and means are provided for ensuring that all parts are correctly positioned when the plates are replaced. An interfering device prevents the adjustment of the face plate whilst the substance is gripped by the, prongs. The face plate need not have a continuous surface, but may consist of a number of strips, and the back plate may be dispensed with. Specifications 337,531 and 337,572 are referred to.
