Filed: 1952-01-30
Abstract: 701,622. Voice-frequency receivers. STANDARD TELEPHONES & CABLES, Ltd. Jan. 30, 1952, No. 2548/52. Class 40 (4) In a V.F. receiver including a limiter and a guard circuit which is substantially ineffective at the signalling frequency and odd harmonics thereof, a negative guarding potential is associated with a standing positive bias and fed back to reduce the signal amplifier gain in the presence of other frequencies. A signal applied at "4 wire in " is amplified in a valve V1, the anode circuit of which comprises a hybrid arrangement T3, T2 in which the anode impedance of valve V1 (preferably high) is balanced by a resistor R1 and a condenser C1 so that signals, e.g. noise, picked up in the outgoing line are not effectively coupled to the final receiving stage through secondaries c and d. The limiter comprises rectifiers W1 and W2 and resistors R3 and R4 which form a potentiometer across the H.T. supply. Harmonics produced in limiting are led to earth by a condenser C4. The anode circuit of valve V2 includes a transformer T5 tuned to the signalling frequency for energizing the signalling relay REL1 and a broadly tuned guard circuit shunted by a series-resonant circuit to suppress the signal frequency. The rectified guard circuit output across condenser C2 is modified by the standing positive potential across a resistance R8 and fed back as a-ve bias to the control grid of valve V2. The bias is prevented from becoming + ve by a rectifier W3. In a modified arrangement, Fig. 2 (not shown), the limiter is incorporated in the input circuit to valve V2.

Title: Alternating current electric circuit-breaker
IPC: H01H33/92
Filed: 1954-06-28
Abstract: 749.211 Oil-break switches. NAAMLOOZE VENNOOTSCHAP FABRIEK VAN ELECTRISCHE APPARATEN VORRHEEN F. HAZEMEIJER & CO. Jan. 28, 1954 [Feb. 2, 1953; Feb. 27, 1953; Feb. 28. 1953], No. 2620/54. Class 38(5) In a liquid-filled circuit-breaker wherein the arc is extinguished by cross-blasting in a chamber 17, the moving contact rod 2 carries at its rear end an insulating sleeve :7 which slides over a fixed rod 8. The contact 2 is actuated by a driving member 11 pivotally connected to a cap 14 embracing the end of the contact and acting on a flange 5 on the contact through a compression spring 16. Thus, when on closing of the breaker, the contacts engage, the member 11 continues to move the cap 14 against the spring 16, and on opening the breaker,. the contacts are separated quickly when a flange 15 on the cap engages the flange 5 after the lost motion between cap 14 and the contact has been absorbed. Damping of contact 2 during closing is effected by the liquid in cap 14, which can only escape through a hole 21, and on opening, by the liquid in sleeve 7 which is forced by the rod 8 through a constricted passage 19 in the contact (through which it enters sleeve 7) and also assists in the extinction of the arc. As a result, the arc is not drawn out too quickly past the vents 18 in chamber 17 in order to give the cross-blast time to effect extinction. A variable opening speed of contact 2 is achieved by the modification shown in Fig. 3 wherein an enlarged head 33 on a projection 34 on rod 8 is arranged to .pass through a constriction 31 in the passage 19 on opening of the contacts. After an initial quick movement of contact 2 the head 33 restricts the passage of liquid through constriction 31 and thereby slows the contact. After the head has passed through the constriction the contact speed again increases. A similar effect is produced by the arrangement shown in Fig. 4 wherein the initial movement of contact 2 causes a spring plunger 42 to be depressed by the liquid, thereby closing apertures 45 in the plunger. When the contact has slowed sufficiently, the plunger rises and allows liquid to flow through apertures 45 with a resulting increase in speed. of the contact. Fig. 7 shows a modification of the embodiment shown in Fig. 1 wherein the sleeve 7 and contact are apertured at 22 to allow liquid to enter the sleeve when the contacts are closed, the cap 14 in this position uncovering said apertures.

Title: Improvements in or relating to the manufacture of bags or containers from paper or any desired flexible material
IPC: B31B3/32
Filed: 1920-01-28
Abstract: 164,071. Drysdale, H. Jan. 28, 1920. Paper bags, making.-Paper bags of tubular or polygonal shape are made by winding a blank on a revolving mandrel and simultaneously carrying the mandrel and the blank past stationary folders which form the bottom of the bag. As shown in Figs. 1 and 1<a>, the mandrel h is journaled in a carriage c which slides on a guide b secured to the bed-plate a of the machine. The mandrel also carries a pinion i which engages a rack secured to the bed-plate, so that the mandrel is revolved as the carriage is moved along the guide b. A folder l, consisting of a plate with a number of teeth or fingers l<1> is secured to the bed-plate parallel with guide b. Thus a blank fed to the mandrel and secured to it, when in the position shown in Fig. 1, will be wound on the mandrel as the carriage moves along the bed, and the fingers will engage and fold down the end projecting out of the blank and form the bottom of the bag. A roller f, journaled on the carriage parallel with the mandrel, holds the blank in contact with the mandrel during its travel. A presser-foot f<1>, pivoted at one end to the carriage, closes on the joint of the bag at the end of the operation and holds it secure until it is removed from the mandrel. In the construction shown, the carriage is reciprocated along the bed by treadle gear, but it may be actuated by an other mechanism. The machine may be made also with two bed-plates, carriages, &c., arranged one above the other, so that two containers of different sizes can be produced at the same time. Fig. 5 shows in front elevation a rotary machine in which two sets of mandrels 19, journaled on spiders 18 which rotate on horizontal shafts 13, are carried in a circular path past stationary folders 31 and are rotated by a gear wheel fixed behind the spiders 18. The blanks, previously gummed, are fed by a reciprocating feed table 55<a> to the mandrel at position C where it is gripped and held against the mandrel by a pressure block 21 mounted on rods which slide in guides on the spider. The paper is pressed against the mandrel as it rotates by a roller 62 carried by an arm 33 which oscillates about the shaft 13. After the bottom is formed, the folds are pressed against the end of the mandrel by a pressure-lever 33 mounted alongside the mandrel and actuated by a rack connected with the pressure block 21. The finished bags are removed from the mandrels at position F. Lined bags may be made by feeding a lining-paper with the blank, and creasing mechanism may be applied to the machine for forming side creases in the bag.
