Title: Improvements in or relating to vehicle door fastening devices
Inventor: JEAVONS PHILIP SWINGEWOOD
IPC: E05B65/32
Filed: 1964-06-12
Abstract: 1,108,435. Latches. WILMOT-BREEDEN Ltd. 11 June, 1965 [12 June. 1964], No. 24401/ 64. Heading E2A. A vehicle door fastening device comprises a "child safety" mechanism which, when the device is fitted is operable from inside the door when the door is closed to render an internal releasing mechanism of the device inoperative and a safety member by which the safety mechanism is cancelled which is inaccessible from inside the vehicle when the door is closed. As shown, in which the device is of the "zero torque" type. comprising a rotary stepped cam 4 and a cam plate 6 journalled in a plastics moulding 3, an external releasing mechanism comprises a slide 12 having a peg 13, for connection to an outside pushbutton, and a projection 14 for engagement with an arm 15 of the cam plate. An internal release mechanism comprises a lever 16 connected to remote control linkage 20. A safety lever 22 is connected to a locking linkage 24 of a remote sill control member 25 having a neutral position 26 from which it is movable against a spring 34 to a child safety position 26a and to a locking position 26b. An L-shaped slide 35 mounted on the moulding 3 includes a peg 36 engaging an indexing spring 37. and a peg 39 which engages a slot 40 on the lever 22. The arrangement is such that movement of member 25 to position 26b acts through link 32 to displace the slide 35 downwardly so that a flange 42 thereon engages a slot 43 in the slide 12 to block movement thereof by the external releasing means. Alternatively, movement of member 25' to position 26a turns lever 22 so that arm 52 thereof blocks an arm 53 of lever 16 and moves slide 35 upwardly to a position in which the head 48 of a spring-loaded push button 44 projecting from the closing edge of the door, is aligned with and enters a lower enlarged width portion of a slot 46 on the slide 35 to prevent return movement of the slide 35, lever 22 and linkage 24, to the neutral position until such time as the door is opened to permit thie push button to be depressed and the parts returned to the neutral position under the action of spring 34. In a modification, Fig. 4 (not shown), a flange 54 on lever 22 is replaced by a peg for co-operation with a modified surface of lever 16.

Abstract: 219,537. Malmsten, N. K. E. Oct. 1, 1923. Mills and apparatus.- Apparatus for disintegrating or mixing artificial fertilizers, or effecting both operations, comprises a rotatable member arranged beneath the bottom opening of a casing so that the material from the casing may drop down upon the member, the axis of rotation of which is substantially concentric with respect to the 'opening and the member being placed close to the opening so that lumps of material cannot pass therebetween; the main part of the member is located beneath the opening and closes the same so that the fertilizer can drop down thereupon at its centre as well as nearer its periphery and be thrown out between the edge of the member and the edge of the opening. The rotary member or disc 6, Fig. 2, is carried at the lower end of a vertical shaft 8 driven by an electric motor 3 and works beneath the open bottom of a casing 7 into which the material is fed through an aperture 9. The disc 6 is slightly larger than the end of the casing so that a narrow horizontal slot is formed therebetween, and a guard or baffle plate 11 may surround the disc. The disc may have ridges 13, Fig. 4, on its upper surface which are preferably inclined to the radius of the disc, and radially-extending recesses 14 may be provided between the ridges. Or a small disc 15, Fig. 5, forming a hub with forwardly-inclined arms 16 may be used. Fig. 6 shows a hub 15<1> with curved arms 16<1>, the concave sides of which face the direction of motion. A portable machine is shown, but the apparatus may be mounted on a stationary framework.

Abstract: 972,732. Covering cores by winding. SCHWERMASCHINENBAU ERNST THALMANN VEB. June 26, 1962, No. 24476/62. Heading B8G. A device 1, 2, 3 for wrapping tapes 5 on an electric cable, includes a ring 6 around the cable where the tapes are being laid on, said ring containing means 7 which, if one or more of the tapes break, moves against the wrapping to press it against the cable.

The means 7 may be a rubber tube, a plurality of bellows, or a plurality of piston and cylinder units. A further magnetic valve 19 may be used to actuate a brake cylinder 18 for stopping the taping machine 1 when the current is switched off and when one or more of the tapes break. The ring 6 is capable of axial movement so that it can move with the cable whilst the cable is stopping. The means 7 includes a safety valve that may be coupled to an acoustic instrument.

So that a squirrel cage induction motor 11, e.g. for a fan in an inaccessible position, or for traction, may have a characteristic similar to that of a D.C. series motor, it is supplied from an A.C. generator 12 whose field 13 is in series with a D.C. series motor 15 which drives it. The D.C. motor circuit may also include a resistor 19 (Fig. 1, not shown), such that the voltage drop across the circuit equals the back e.m.f. of the motor at the middle of its speed range, to ensure an approximately constant power output. As shown, this resistor is replaced by a constant speed negative booster 23. In addition, to a series field winding 21, the booster may have a winding 25 in series with a rectifier R2 and a battery B1 across the D.C. supply; the battery voltage is such that, if the supply voltage is at a minimum, no current flows through field winding 25, but if this voltage rises a current flows in a direction to cause the " booster " to deduct the additional voltage, so that the voltage at the motor terminals remains constant.

[Also in Division H1] A magnetic tape 30, carrying longitudinal field variation signal patterns is fed past a Hall head whose active parts are a thick layer 12 of InAs or InSb of P-type to which a transverse Hall control current is applied by contacts 16 and a thin, N- type layer 14 produced by doping one free of the layer 12 with Se or Te, to which output electrodes 22 are fastened and whose thickness forms the effective transducing "gap" length, due to the high resistivity of the P-layer 12 and the high electron mobility in the N-layer 14. The structure is encapsulated in epoxy resin (not shown) to support the leads. The doping may be done by any known process, but is preferably achieved by evaporating the doping material at 350C. on to the layer 12 for 20 minutes followed by a period at 500C. to cause interpenetration to about 5% of the total thickness of the structure.
