Patent GB-1473731-A (GB)
Title: Method of making electrical connections
IPC: H01R4/02
Filed: 1974-07-30
Abstract: 1473731 Making electrical connections FIAT SpA 30 July 1974 [21 Sept 1973] 33650/74 Heading B3A [Also in Division H2] A method of connecting a terminal 16 to an insulated wire f4 of a cable 10 having a plurality of wires f1-fn, the wires being held together by an outer insulating cover, comprises baring one end of the wire f4, removing a part of the outer cover at a point intermediate its length, placing a conductive element which is to form the terminal adjacent the wires of the cable at this point, surrounding a part of the element and the wires with a hardenable, conductive liquid, applying a voltage across the wire f4 and the element which is increased until it breaks down the insulation of the wire causing perforations to be formed in it so that the conductive liquid contacts the core of the wire f4, and subsequently hardening the conductive liquid. The hardenable, conductive liquid may be a resin containing silver and graphite or a tin-based solder. The voltage is applied by a battery 24 through resistors 26, 30 and it increases until the breakdown of the wire insulation occurs whereupon a capacitor 28 discharges and the voltage falls rapidly.

Title: Improved electric motor control system

IPC: H02P7/298
Filed: 1966-07-27
Abstract: 1,125,310. Control of D.C. motors. ALLISCHALMERS MFG. CO. 27 July, 1966 [2 Aug., 1965], No. 33728/66. Heading H2J. When the average current supplied from battery 11 to series motor 10 through pulse width-modulated switch 20 has a high value, the average voltage developed across the switch is sufficient to render transistor 47 conductive, whereby transistor 48 is switched off and relay 51 is de-energized to open contacts 51c in parallel with field winding 13. As the motor current decreases below a.first pre-selected level and the voltage across the switch is reduced, the transistors 47, 48 are respectively turned off-and-on so that the field winding 13 is shunted by resistor 15. While the transistor 48 is conductive, it requires a higher voltage than before to turn the transistor 47 on again. The resistor 15 is thus disconnected from the field winding 13 only if the motor current exceeds a second preselected level which is higher than the first.

Abstract: 509,382. Controlling hydraulic accumulators; indicating liquid-level. SCHLOEMANN AKT.- GES. Nov. 23, 1938, No. 34080. Convention date, Nov. 24, 1937. [Class 69 (ii)] [Also in Groups XVIII and XXXVII] Control means for a compressed air loaded hydraulic accumulator 1 comprises a float 5 in a tube 4 communicating at the top and bottom with the accumulator, the float acting as an armature for an electromagnet 6 slidably mounted outside the tube and having a projection 7 which actuates contacts 8 in the control circuits consequent upon movement of the column of liquid in the tube 4 in accordance with variations in the liquid level in the accumulator. The member 6 carries a pointer 10 co-operating with a scale 11 for indicating the liquid level in the accumulator, and is counterbalanced by a weight 14. The member 5 may be such that it does not float, in which case the weight 14 is arranged to counterbalance partially the combined weight of the members 5, 6; if the circuit to the electromagnet 6 becomes interrupted, the member 5 falls to the bottom of the tube; a pulley B is automatically clutched to the pulley A of the counterweighting system, and a weight D rotates the pulley to cause the member 6 to move to the bottom of the tube, so that electromagnetic coupling of the members 5, 6 is ensured when the electromagnet is re-energised. In a modification, the single armature co-operates with a number of electromagnets, each having a limited travel, and arranged to actuate individual switches. Specification 477,553 is referred to.

Abstract: 956,159. Refuse receptacle holders. CARTEM ENGINEERING Ltd. Sept. 26, 1962 [Sept. 26, 1961; Oct. 18, 1961], Nos. 34431/61 and 37355/61. Heading B8C. A holder for a paper sack for refuse comprises a bracket member which is mounted to a support such as a wall, a frame which is inserted into the mouth of a receptacle and means providing a connection between these two members, the arrangement being such that connection between the frame member and the bracket member firmly clamps the sack in position.  In one embodiment the bracket member consists of a metal strip 1 having bent endportions 2, and a ledge 7 affixed to the front. The frame member consists of a U-shaped metal strip 4 (hinged at 6 to the bracket member) and a bar portion 4a fixed to the strip 4 by lugs 8 and located immediately above the ledge 7. The holder may also be fitted with a lid 9. To use the holder, the lid is first raised and then the frame member so that the bar 4a moves sufficiently away from the ledge 7. The mouth of the sack is then passed upwardly around the outside of the frame member and folded over inwardly and both are then lowered, so that when the bar 4a comes into contact with the ledge 7 again, the sack is clamped therebetween as shown in Fig. 2. The sack is also clamped by the lugs 8 acting against the bracket member 1, and a hinge 10 may also be fitted on the frame member 4 to secure the sack at the front. In a second embodiment, the frame member consists of a complete rectangular detachable loop, the lugs 8a equivalent to the lugs 8, being fitted with downwardly extending hooks 12, Fig. 5, which engage the strip 1. In operation the frame is detached, a sack mouth is passed upwardly around and over as in the first embodiment and the frame member is re-attached causing the hooks to pierce the sack before it is clamped. In further variations (not shown), the frame may be of U-shape, the front portion being omitted, or of elliptical or other shape. The bracket member may extend downwards to hold the sack clear of the wall &c. and to provide storage space for spare sacks.

Pivoted-sliding windows. -A horizontally - sliding window, of the kind in which the sash when slid open can be turned inwards for cleaning, has a keyoperated bolt adapted to prevent the movement of the sash to the cleaning position. The sash c, Fig. 1, is guided, as it slides to the right to open the window, by means of a stud d at the top and studs e, pintles f, and bolts g at the top and bottom which engage in channels formed by flanges h on the fixed window frame a. In the open position of the sash, the stud d comes opposite a notch in the flange h and at the same time the studs e come opposite segmental slots j, shown in plan in Fig. 5, in guide-brackets k, and the pintles f engage in slotted eyes l in the said brackets. In this open position, therefore, the sash is free to swing inwards about the pintles f when the bolts g have been released from their engagement behind the flange h. The releasing means consists of a follower o, Fig. 9, in which a keyhole n is formed linked by a rigid link p to the bolt g. In a modification, the locking means may be provided on the sash c or the frame a to provide, when in the operative position, an abutment limiting the sliding movement of the sash so that the projections and notches do not mutually register.
