Filed: 1965-05-08
Abstract: A conveyer system comprises a track 10, Fig. 4, supporting trolleys 11 movable in a direction A along the track by dogs 20, Fig. 2 (not shown), on an endless driving chain 19 engaging driving bars 21 on the trolleys, means 22, 23, 24 for disconnecting the trolleys from the driving chain to permit the former to be brought to rest at selected positions along the track, the invention being characterized in that each trolley has mounted thereon, for pivotal movement about an axis 30 transverse to the direction A, a cam member 27 having a convexedly curved cam face 31 adapted to frictionally engage the upwardly facing part 10c of the track, the cam face 31 in a circumferential direction opposite to the direction A being spaced by a progressively increasing distance from the pivot axis 30 so that at all times a curved portion of the cam contacts the track to the rear of the pivot axis, whereby forward movement of the trolley is not restrained by the cam member, while in the event of a trolley moving rearwardly (as shown in Fig. 4) the cam member rolls on the track (with a wedging action) and raises the rear end of the trolley to apply to the cam member a couple, derived from the weight of the trolley and its load, acting in a clockwise direction to resist the rearward trolley movement. The trolley has a plate-like body 12 supported on the track, which is of cruciform configuration in crosssection, Fig. 7 (not shown), by two pairs of wheels 15 and four guide wheels 17. Mounted on the body is a pivoted striker plate 23 which when engaged with a stop 24, Fig. 2 (not shown), on the track rotates a member 22 pivoted on the body to raise the associated driving dog from the driving bar 21. The trolley also has a tail member 26, 25, Fig. 2 (not shown), which when contacted by a following trolley rotates the striker plate of that trolley to disconnect the drive therefrom. Two cam members 27 are provided on each trolley and rotatably mounted on a shaft 28 projecting on opposite sides of the body. Each cam member is urged to the trackengaging position by a light flat spiral spring as described with reference to Fig. 8 (not shown) and the nature of the curve on the cam member is described with reference to Fig. 9 (not shown). Extreme rotation of the cam member causes a flat portion 31c thereof to engage the track and skid thereon. Reference has been directed by the Comptroller to Specification 1,047,621.

Title: Epoxy resin containing a curing catalyst mixture of a polymercaptan and a fused ringamine
IPC: C08G59/66

Title: Semiconductor devices having a field effect transistor structure
IPC: H01L29/40
Filed: 1967-05-13
Abstract: One electrode 7 of a junction-gate field effect transistor is shielded from the main bulk 2 of the semi-conductor body which comprises the gate region, by means of a shielding layer 13 which is electrically connected to the other electrode 6 of the transistor. In the embodiment shown the shielding layer 13 comprises an N-type surface region of the semi-conductor body connected to the N-type source (or drain) region 4 by a region 15. The shielding layer is isolated from the P-type bulk 2 of the body by the junction 14. The shielding layer may alternatively comprise a metal coating insulated from the body 2 by an insulating coating, e.g. of silicon oxide or silicon nitride, and connected to the electrode 6 by a conductor deposited on the insulating coating. In the form illustrated the electrodes 6, 7 are interdigitated and are connected to the source and drain regions through apertures in the insulation 3. The body 2 is of P-type silicon 61 carrying a relatively high resistivity N-type epitaxial layer 62. Diffusion of boron through a mask isolates the required N-type pattern, and a further diffusion of phosphorus between the source and drain regions converts some of the material there to P-type and thus restricts the thickness of the N-type channel. The electrodes 6, 7 are of vapour deposited aluminium selectively etched to the required shape. Alternatively the device may be manufactured simply by two diffusion steps into a substrate. The semi-conductor body may also be of germanium or an A III B V compound. Two independently connected gate regions may be provided, and the shielding layer may be connected to the electrode 6 outside the envelope which encloses the device.

Patent ES-355299-A1 (ES)
Title: Electromagnetic relays
IPC: H01H51/01
Filed: 1968-06-21
Abstract: An electromagnetic relay having separate operate and release windings is retained operated by a permanent magnet, and the latter is opposed on energization of the release winding which has a flux path parallel to that of the operate winding. The operate winding 7 is mounted on a core 3 which is slightly shorter than the combined core 2 and permanent magnet 4 parallel thereto. The armature 5 rocks on the yoke 1 and is biased away from the cores. On energization of the winding 7, in the direction shown, the armature 5 is attracted to the core 3 and moves to engage the magnet 4 which retains the armature after de-energization of the winding. The release winding 8 on the core 2 may be energized in opposition to the permanent magnet 4 to release the armature. When the armature is held in the attracted position, spurious energization of the winding 7 in either direction or of the winding 8 in reverse of its release direction will assist the permanent magnet in retaining the armature.

Title: Filtered socket for electronic circuit board
IPC: H01R13/7197
Filed: 1972-06-13
Abstract: A filtered socket decouples the pin of an electronic circuit device such as a transistor or a thin film amplifier. The tubular socket is constructed of a resilient metal with a pin receiving opening at one end and a resilient tail at the other end. A tubular filter is soldered onto the socket. This filter has a metal flange which is positioned against the plated through circuit in a hole on the circuit board.
