IPC: H01F41/06
Filed: 1922-10-28
Abstract: 213,301. Gill, B. Oct. 28, 1922. Addition to 201,586. Coils, machines and apparatus for making.- In a coil-winding device as described in the parent Specification, an improved packing device is used for pressing on the coil sides before they are spread, and swinging coil end-guides and side-guides, movable towards each other, are employed. The packing device, Fig. 1, consists of a block 3 feathered at 5 on the winding guide 7 to which it may be locked. The block carries a presser 9, which may be screwed down on the coil by a screw 13, and a side. presser 19 controlled by a pin 15 and adjusting-screw 25. Fig. 2 shows the coil end-guides 48, 49 carried by bars 50, 52 which are mounted so as to swivel at 62 on the block 64 and so as to be adjustable for different coil widths by means of a nut 56. The block 64 slides freely on the longitudinal bar 30 and may be locked at any position thereon. The coil side-guides 7 are carried on bars 40 supported by rods 42 which slide in sleeves 44 in the members on the spreading screws 46 so that the sides of the coil, when clamped to the side-guides by means of the pressers, Fig. 1, may be moved towards each other. When the coil has been wound with the parts as in Fig. 2, the blocks 64 are undamped from the bar 30 and the side-guides are moved towards each other, the blocks 64 simultaneously moving inwards. The journals 62 are then unclamped and the bars 40 are moved oppositely, perpendicularly to the coiling plane, to spread the coil, the end guides meanwhile swinging in their supports. By setting one of the bars 40 substantially in line with the end guides 68. Fig. 3, a rhomboidal loop for an Eickemeyer coil mav be wound. The coil is formed. as shown in dotted lines, by moving one side guide towards the other after unclamping the blocks 64.

Title: Umbrella stick, walking stick or other like stick usable as a seat
IPC: A45B5/00
Filed: 1926-11-22
Abstract: 261,789. Trautmann, J. Nov. 21, 1925, [Convention date]. Stationary mixers with rotary stirrers.-Reacting substances, together with metals or other catalyzers in some cases, are brought into intimate contact by threshing. A catalyst may be applied as a coating to the threshing members and in some cases to the walls of the reaction chamber. The raw materials may also be dragged through the molten catalyst. Reference is made to the hydrogenation of carbon or oil and to the synthesis of oils from carbon monoxide and hydrogen, molten tin being used as a catalyst. In one construction, beaters e, Fig. 1, are pivotally mounted on arms on a rotary shaft passing through a closed chamber a surrounded by heating jackets b. Materials for the reaction are delivered under pressure by a pipe g so as to be carried by the beaters into the molten bath, which may be heated electrically. Solid and liquid products escape through pipes h, and gases through pipes j. In another construction, a number of discs mounted on a shaft are connected at their peripheries by bars parallel to the shaft, the molten material being partly broken up into a mist. Reaction substances pass through the chamber in a direction parallel to the shaft, and are deflected by corrugations on the roof of the chamber. The Specification as open to inspection under Sect. 91 (3) (a) describes also a chamber provided at top and bottom with rotating atomizers u, Fig. 5 (Cancelled). Reaction substances are driven by a blower or pump w from a vessel x to the reaction chamber. Solid products leave at t, and gases may escape or be drawn off through s. This subject-matter does not appear in the Specification as accepted.

Abstract: 676,424. Discharge apparatus. WESTERN ELECTRIC CO., Inc. Nov. 16, 1948 [Dec. 4, 1947; Aug. 14, 1948], No. 29781/48. Addition to 676,411. Drawings to Specification. Classes 39 (i) and 39 (iv). [Also in Group XL (b)] A solid insulating body is said to be made conducting by the impact of radiation (including X and y rays, a and # particles, electrons, protons and mesons) and is irradiated with light to prevent the formation of a space charge. The insulating body, preferably of diamond, is a single crystal having electrodes as disclosed in the parent Specification. It is suggested that electrons released from atoms may enter the field of foreign atoms or imperfections in the crystal and thus not be collected before the initiating impact is succeeded by another, thus resulting in an effect similar to voltage saturation. It is stated that irradiation with light avoids this effect. The wavelength of the light may be selected. The insulating materials may be purified silicon carbide or stibnite as well as those materials given in the parent Specification.

Title: Improvements in or relating to telephone systems
IPC: H04M19/06
Filed: 1932-10-25
Abstract: 403,508. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and PUCKETTE, C. C., c/o General Electric Co., Stoke, Coventry. Oct. 25, 1932, No. 29836. [Class 40 (iv).] In an arrangement in which current is supplied to a sub-exchange over a junction from the main exchange either normally or in exceptional circumstances, the comparatively heavy current necessary for driving switches is obtained by the use of a motor connected to the junction and provided with a flywheel or other energy-storing device so as to act for short periods as a generator. The motor is preferably of a high-speed permanent-magnet type having a low resistance armature. In Fig. 1, current is received over the junction 4, 5 or over a single wire with an earth return. The switches are connected to leads 2, while the various relays are connected to leads 3. As long as the sub-exchange is in use, relay X is operative and connects current to the motor M, which by virtue of the stored energy in its flywheel acts as a generator when the switches draw current from leads 2 and maintains the voltage for a sufficient time for their operation. Alternatively, the motor M may be started only when impulsing is about to take place. In Fig. 2, the current is normally obtained from the local A.C. supply 12, relay Y being operated thereby. Upon failure of the supply however, relay Y falls back and current is received over the last-choice junction 6, 7, which is marked busy at both ends, and lamp AL is lighted at the main exchange. The motor M is started, and acts as a generator when comparatively heavy current is required as in Fig. 1. If desired, the current from the main exchange may be received over several junctions in parallel. The arrangement may be employed to supplement a local battery in the event of failure of the charging plant or excessive discharge of the battery. Specification 388,935 is referred to.

Title: Improvements relating to hydraulic drive for vehicles such as industrial trucks
Inventor: QUAYLE GEORGE FRANCIS
IPC: F16H61/40
Filed: 1955-10-20
Abstract: 796,230. Hydraulic transmission of power. YALE & TOWNE MANUFACTURING CO. Oct. 20, 1955, No. 29984/55. Class 69 (2). In an hydraulic transmission for a vehicle, pumps 10, 11 supply a motor M through a reversing valve 32, and the pressure developed by the pumps is applied to the valve to tend to move it into a position for cutting off flow to the motor. During normal working the pumps 10, 11 deliver to a passage 21 and thence, according to which side of the neutral position (shown) that the valve 32 is displaced, through a line 49 or 50 to the motor. In neutral position the liquid passes through ports 41 and a bore 42 in the valve to the inlet line 13 of the pumps. A passage 56 in communication with line 50 applies the pressure in this line to a shoulder 53 of the valve. Similarly a passage 55 communicating with line 49 directs pressure to a shoulder 54. The valve is displaced from neutral by a manually operated treadle 57 acting through a spring 65, and on the occurrence of an overload the pressure in the delivery line 49 or 50 acts upon the shoulder 54 or 53 to move the valve to neutral against the pressure of the spring 65. Normally the plunp 11 delivers to the passage 21 through a lightly loaded check valve 25. If the pressure in passage 21 increases, due, for example, to the vehicle going up hill, this pressure acts on the left-hand end of a valve sleeve 18, and moves it to the right against a spring 28, to by-pass the delivery of the pump 11. Check valve 25 then closes so that pump 10 alone supplies the motor. The valve sleeve 18 is actuated at half the pressure required to close the valve 32. Coasting.-If motor M over-runs, additional liquid is drawn from a reservoir through a check valve 72 or 73 to the supply line 49 or 50. Braking.-If the valve 32 is moved to neutral, the blocking of the exhaust line brakes the motor. The pressure in the exhaust line, acting on the associated shoulder of the valve, tends to displace it from neutral against the pressure of spring 65, thus limiting the pressure in the exhaust line and determining the maximum braking pressure.
