Title: Improvements in or relating to control means for electrical circuits
IPC: G05F1/32
Filed: 1943-06-29
Abstract: 569,600. Voltage and current regulation. HARMER, H. M. June 29, 1943, No. 10503. [Class 38 (iv)] A device of the saturable reactor type for controlling current in an A.C. circuit comprises equal inductances a-d connected as a bridge, across one diagonal of which a control current is applied whilst the circuit to be controlled is connected across the other diagonal. The control current may be D.C. or A.C. and, in the latter case, control may be effected by variation of either the amplitude or phase of the control current. The device is of particular application in the voltage stabilizing arrangements described in Specifications 493,362, 515,207, 521,314, 524,565 and 554,467. Fig. 2 shows such an arrangement in which the bridge a-d, forming a resonant circuit with a condenser C, is connected in series with the primary winding of a transformer 6 across a fluctuating input voltage e, e. A stabilized output voltage f, f is obtained from the terminals 1, 2 of the bridge and the secondary winding s of the transformer in series. A further transformer 5 having its primary connected across the input terminals and its secondary across the terminals 3, 4 of the bridge provides compensation for the fluctuating input voltage. Variation of output voltage with load is compensated by the secondary winding s which on low loads provides a voltage opposing that across the terminals 1, 2 of the bridge. The bucking effect of the winding s is first reduced to zero and finally becomes a boost as the load current is increased, due to the changing phase of the voltages across the bridge and primary winding of transformer 6. The inductances a-d may be provided with secondary windings for supplying additional load circuits.

Title: New polyethers
Inventor: ALLPORT DENNIS CHARLTON
IPC: C08G18/50
Filed: 1962-03-15
Abstract: Compounds having polyether chains terminated by primary amine groups are prepared by the reduction of the corresponding nitriles <FORM:0984510/C2/1> where R1 and R2 are hydrocarbon or halohydrocarbon groups, or one may be hydrogen, R3 and R4 are hydrogen, or one may be a methyl group, a and m are greater than 1, and X is the residue of a compound XHa having a hydrogen atoms reactive towards cyclic oxides. The reduction may be effected by any conventional nitrile-reducing agent, such as sodium amalgam/ethanol, but catalytic hydrogenation is preferred, platinum, nickel or, in particular, cobalt catalysts being suitable.  The hydrogenation may be effected in the liquid phase at 20-200 atmospheres and 70-150 DEG C., with or without diluents, such as methanol, ethanol, or dioxan, in the presence of excess ammonia. Instead of ammonia excess acetic anhydride may be used, in the presence of sodium acetate (optional), in which case the amine is recovered by hydrolysis, and pressures and temperatures as low as 50 p.s.i. and 50 DEG  C. may be sufficient. The examples describe the hydrogenation of a b -cyanoethyl polyoxypropylene of molecular weight about 1000, in the presence of Raney nickel in acetic anhydride sodium acetate, and the recovery of the product by treatment with sulphuric acid, then sodium hydroxide, before distilling, and the hydrogenation of the same nitrile, and of a cyanoethylated oxypropylated trimethyl propane, in the presence of cobalt on kieselguhr in ammonia/methanol.  Specification 984,372 is referred to.ALSO:Compounds having polyether chains terminated by primary amine groups are prepared by the reduction of the corresponding nitriles X[-(-CHR1-CHR2-O-)-mCHR3-CHR4 -CN]n where R1 and R2 are hydrocarbon or halohydrocarbon, or one may be hydrogen, R3 and R4 are hydrogen, or one may be a methyl group, a and m are greater than 1, and X is the polyvalent residue of a compound XHa having a hydrogen atoms reactive towards cyclic oxides.

Title: Thread-cutting mechanism for sewing machines
IPC: D05B73/12
Filed: 1939-04-06
Abstract: 509,592. Sewing-machines. FAIRWEATHER, W. C. (Singer Manufacturing Co.). April 6, 1939, No. 10739. [Class 112] In a sewing-machine having thread-cutting and thread-gripping means mounted on a carrier-lever, the cutting means is arranged to be adjustable independently of the gripping means so that its path of operation may be varied. The invention particularly relates, and is shown applied, to a buttonhole sewing-machine in which the work-clamp and stitch-forming devices are relatively movable, in the longitudinal direction of the buttonhole, between cutting and stitching positions and in which a loop of needle-thread is drawn out after stitching by the return of the parts to their initial positions, this loop then being severed close to the work and gripped close to the loop-retaining means ; the position of the gripping means is fixed by that of the loop retaining means, but the cutting point is determined by the position of the last stitch, which is variable according to the length of the buttonhole, and the cutting means therefore requires to be adjustable. In the arrangement shown, the cutting and gripping means are mounted on a carrier arm 27 actuated from a cam on the pattern shaft 18. The member 43 carrying the cutter-blades 24 has a slotted base member 44 formed with a rib fitting into a channel 53 in the carrier 27 so that it is located laterally, but slidable longitudinally. The member 39 carrying the gripper jaws 33, 34 has a channelled base 48 fitting over the part 44, and is secured to the carrier 27 by a bolt 46 which also clamps the member 43 in its adjusted position. One edge of the member 44 rests on a wedge 54 slidably adjustable on the carrier 27 so that the members 39, 43 can be tilted slightly to adjust the radius of action of the cutting and gripping devices. A spatulate guide plate 26 is secured to the fixed scissor blade 24 ; the pivoted blade 25 is actuated by a pin engaging a cam slot in a fixed member 57. The pivoted gripper jaw 34 is normally held open against a spring by a latch 36 on a rock-shaft carrying an arm 40 with a pin engaging fixed cam members 42 so that the jaw is released to close at the end of the upward movement of the carrier 27 and is closed (its tail being bevelled so that the latch can ride on to it) at the end of the return movement ; the turret carrying the lower stitch-forming devices and needle throat-plate 11 also carries a leather wiperblade which removes the waste-thread from the gripper during the return rotation of the turret after a buttonhole-sewing cycle.

Title: Improvements in and relating to safety guards of metal-working presses and like heavy slow-acting machines
IPC: F16P3/08
Filed: 1940-06-22
Abstract: 541,573. Locks ; catches. PRESTON, P. June 22, 1940, No. 10746. [Class 44] [Also in Group XXIV] Consists in safety guard means for presses and like heavy slow - acting machines, wherein the guard and the machine control means are provided with separate locks operable by a single key which can be removed from either lock only when the guard is closed and locked and the controller is " off " and locked. The guard, e.g. a collapsable gate 11 gives access through opening 12 to the working zone. A controller, in the form of a lever 15, Fig. 2, is attached to stems 14 of valves in a chest 13. A quadrant plate 17 on the lever has a recess 18 which can be entered by a pin 19 on a lever 20 when the controller 15 is in mid-position and the press inactive. The lever 20 is pivoted at 21 and carries a hooked beak 23 adapted to enter a lock 24. The guard also has a hooked beak 27 adapted to enter a lock 25, Fig. 1. These locks are actuated by a single key and are so constructed that they can only be inserted in or withdrawn from the locks when the latter are in the locking condition. The case 28, Fig. 4, of the lock encloses a rotatable tumbler 29 with a hooked part 31 adapted to enter a recess in the beak 27 of the gate 11. The tumbler which may be acted upon by a return spring 30, has a shoulder 32 which, in the unlocking position is in line with the beak 27 so that when the gate is closed the beak forces the tumbler to rotate counter-clockwise into the position shown to cause the hook 31 to engage the recess in and lock the beak. A shoulder 33 on the tumbler is adapted, in the locking position to be engaged by a detent 35 loaded by spring 36. A second shoulder 34 is adapted to engage a stop 34A. The detent, which is pivoted, has a triangular or polygonal bore adapted to be entered by a similarly shaped key, the lock case having a similarly shaped key-hole 38. Upon inserting the key and turning it clockwise, the detent is retracted and the gate may be withdrawn at the same time turning the tumbler 29 clockwise. The polygonal holes only register, and therefore the key can only be inserted and withdrawn, when the tumbler is in locking position. The locks 24, 25 are both of this type. In modifications, the lever 20(1) carries a stirrup controlling the movement of a clutch-operating pedal and (2) has a projection adapted to enter a recess in a valve-controlling hand-wheel. According to the Provisional Specification, a press unit comprises a main press component and an auxiliary component, the power-operated element of which must be moved to a non-obstructive position before the operator can gain access to the main press. Separate locks are applied to the controllers of both components.

Title: Improvements in or relating to cigarette making machinery
IPC: A24C5/34
Filed: 1931-04-13
Abstract: 375,463. Weighing-apparatus fitted to cigarette-making machines. MOLINS, W. E., BEST, C., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. April 13, 1931, No. 10798. [Class 143.] In means whereby the feed of tobacco to a cigarette-making machine is automatically varied by mechanism connected to a weighing- apparatus arranged to receive a definite number of cigarettes automatically selected at intervals from the output of the machine, the finished cigarettes are delivered alternately on to two parts 3a, 3b of a conveyer 3 by deflectors 17, 19, and means are provided whereby the flap 19 is raised at intervals about its pivot 19a from the dotted to the full-line position in Fig. 3, so that, for example, fifty cigarettes are lifted by a conveyer chain 14 up a slope 20 to a scalepan 6. The weight is indicated at 8, 9, and adjusts a member 11 engaged by a feeler 10, which is connected to the feed control in the manner described in Specification 327,098, [Class 130, Tobacco]. The flap 19 is raised by linkwork 29, 31, 32 connecting the pivot 19a to a lever 28, 26, between which and a member 23 oscillated by a connecting-rod 22, a lever 27 is inserted at the desired intervals of weighing. Before weighing is to commence, the lever 27 is above the member 23, which therefore oscillates without affecting the lever 26 and the flap 19. At the required time, however, the lever 27 is pressed by a spring down a step on a rotating face-cam 34, so as to become effective between the members 23, 26, raising the flap 19. The lever 27, and therefore the flap, is held in the position to which it is moved by the member 23, by a spring catch 40. After fifty cigarettes have been delivered into the scale-pan, the lever 27 is depressed into a second step on the cam 34, releasing the flap, and is then swung to the right about a pivot 42 by a cam 36 engaging an arm 43. The lever 27 is then beneath a pawl 46, but is raised into engagement therewith by another face-cam 35. When the desired interval of time has passed for another weighing, the pawl 46 is disengaged by a cam 44. This cam is formed with groups of projections at different heights, so that by adjusting the cam axially by means of a screw 48, the time interval between successive weighings can be altered. The device may be put out of action by turning a knob 52 which rotates a cam 54 to move the cam 44 out of the range of the pawl 46. After each weighing operation, the scale-pan is tilted to empty the cigarettes on to the conveyer 3, by an arm 13, Fig. 1, connected to an arm 50, Fig. 2, actuated by a cam 49. In a modification, the chain conveyer 14 is replaced by rotating pocketed discs, and the flap 19 is raised by a cam formed as a fusee or screw-thread. Instead of being collected from the cutting-mechanism, the batches of cigarettes to be weighed may be collected later from the conveyer 3 ; or they may continue in their straight path from the continuousrod cutting-mechanism instead of being deflected on to the delivery belt.
