Abstract: 1288260 Combine harvesters ROBERT BOSCH GmbH 31 Oct 1969 [2 Nov 1968] 53409/69 Heading A1F [Also in Division F2] In a drive for vehicles, e.g. combine harvesters, including a main hydrostatic transmission 19 for harvester travel, and a power takeoff to a conveyor 17 driven through a clutch 56 to deliver material to a threshing cylinder 16 driven directly by the main diesel engine 10, overload of the threshing cylinder 16 as indicated by a fall in engine speed is effective initially to downshift, the hydrostatic transmission to slow down the harvester and hence decrease the amount of material delivered by the conveyor to the threshing cylinder and if overload persists, to disengage the clutch 56 to prevent any material from being delivered to the thresher. As shown, the engine 10 has a fuel injection pump adjusted at 12, and the travel of the regulating rod 13 of the pump is limited by a manually adjustable stop 15. The hydrostatic transmission comprises a variable pump 18 and a motor 33, the pump being adjusted manually by a lever 20 through a lost-motion spring coupling 21, or by an automatic override servo 22. An engine-driven make-up pump 23 delivers apply-pressure to the clutch servo 57 through a valve 34, subjected at opposite ends to the pressure of the make-up pump from opposite sides of a restricted orifice valve 26, to pressure-drop across the valve 26 being normally sufficient to maintain the valve 34 depressed and the clutch 56 engaged. The valve 34 also normally cuts off pressure supply to the pump 18 adjusting servo 22. On overload of the threshing cylinder 16, the rod 13 abuts the stop 15 and the engine speed 10 falls, decreasing the pump 23 output and hence the pressure drop across valve 26. The control valve 34 begins to move up to connect pump 23 to the adjusting servo 22 to decrease pump 18 output and decrease the harvester speed and hence the amount of material being fed by conveyor 17. The manual lever 20 remains in its set position. If the overload persists, the valve 34 moves further up to cut-off fluid supply to clutch servo 57 to disengage the clutch 56 and stop conveyor 17. When the speed of the engine again rises, the clutch 56 is re-engaged, and the pump 18 output returned to its original setting by spring 21. Throttle valves 42, 52 in the return line from the servo 22 and the line from the bottom of valve 34 delay the return to normal operation of the pump 18 and the clutch 56, respectively, to prevent a renewed overload.

Title: Photographic camera with electro-magnetically controlled shutter
Inventor: NOACK ROLF
IPC: G03B9/58
Filed: 1966-11-30
Abstract: 1,136,437. Photographic camera. PENTACON DRESDEN, KAMERA UND KINOWERKE VEB. Nov.30, 1966, No.53546/66. Heading G2A. The invention relates to a photographic camera wherein on actuation of the shutter release, a blocking lever is pivoted preventing the shutter drive member completing its run down while the shutter blades are open, the blocking lever being moved by a striker lever activated after an interval by an electromagnetic timer device. As shown in Fig.1, the shutter release 23 is in the rest position with the shutter blade 4 closed. Depression of the release 23 closes a switch S1 to activate an electromagnet 33 linked to a timer device 34, and a projection 27 on the release pivots a cocking lever 12. An arm 14 of the cocking lever 12 pivots the drive lever 8 anti-clockwise over a drive pin 6 projecting through the shutter blades 4, and an arm 15 pivots a blocking lever 20. As the arm 14 slips past the drive lever 8, the lever 8 is rotated clockwise by a spring 41, thereby turning the pin 6 thus opening the blade 4, when a blocking pin 13 on the drive lever 8 is stopped by a pawl 19 on the blocking lever 20. After a time interval determined by the timer device 34, which may be linked to a photo-cell, the electromagnet 33 is deactivated and the striker lever 32 is pivoted by a spring 38 to strike an arm 31 of the blocking lever 20 to cause it to pivot, thereby moving the pawl 19 and releasing the driver lever 8 to complete the closing part of its run. For "B" exposures a lever 26 prevents movement of the striker lever 32. In an alternative embodiment, Fig. 4 (not shown), using a magnet of low power, the striker lever 32 is held by an armature lever which is attracted by the magnet after the determined time interval.

Title: Crimped voluminous yarns containing composite polyester filaments and a process for the production thereof
IPC: D01D5/30
Filed: 1965-12-17
Abstract: 1,093,170. Voluminous composite polyester yarns. SOCIETE DE LA VISCOSE SUISSE. Dec. 17, 1965 [Dec. 18, 1964], No. 53701/65. Heading B5B. [Also in Division D1] Yarns consisting wholly of side - by - side composite polyester filaments having a capacity for crimping or becoming voluminous spontaneously, or partly of such composite filaments and partly of unitary polyester filaments, are produced by melt spinning simultaneously through each of some or each of all of the orifices of a spinneret two polyesters of identical chemical composition and the same or different mean molecular weights to form composite filaments the components of which, before the filaments are stretched, differ in double refraction by at least 0À002, stretching them at a temperature of at least 65‹ C., and subsequently relaxing the tension on the yarns. In the case of yarns consisting of both composite and unitary or homogeneous filaments, some of the polyester melts are separately extruded through different spinneret orifices to form unitary filaments, which are collected in a bundle with the composite filaments to form the yarn. When the yarns consist exclusively of composite filaments they may be heat set while free from tension after having undergone spontaneous crimping. Yarns containing both composite and unitary filaments may be stabilized after relaxation of the stretching tension by twisting and/or heat-setting under tension. The polyesters constituting the composite filaments preferably differ in their reduced viscosity by at least 0À1. Fibre-forming saturated polyesters having a melting point above 100‹ C. may be used for the production of the yarns, including polyethylene terephthalate, poly - (1,4 - dihydroxymethylcyclohexane terephthalate), copolyesters of terephthalic acid, isophthalic acid and ethylene glycol, and also polyester ethers. A melt spinning head 1 for the production of yarns of composite filaments (Figs. 1 and 2) is subdivided internally into two chambers 2 and 3 supplied with molten polyesters P1 and P2, each by means of a titre pump. The two melts flow through the openings 4 and 5 into the chambers 6 and 7. Along the edge 9 of tapering partition 8 the two melts P1 and P2 unite and flow without mixing jointly through the spinneret orifices 10. Figs. 5 and 6 illustrate a melt spinning head 14 for the production of yarns consisting of both composite and unitary filaments. The melts P1 and P2 flow from the two ante-chambers 15 and 16 through a number of openings 17 and 18 into chambers 19 and 20 separated by the partition 21 tapering downwardly to an edge 22 and extending almost as far as the inlets of the spinneret orifices 23. The two melts P1 and P2 flow together from the chamber 19 and 20 through the spinneret orifices 23 and form separate composite filaments. Only the melt P1 flows out of the spinneret orifices 24, and only the melt P2 out of orifices 25, unitary filaments being thereby formed.

IPC: F23D14/32
Filed: 1967-11-27
Abstract: 1,220,828. Burners. BRITISH INSULATED CALLENDER'S CABLES Ltd. 26 Feb., 1969 [27 Nov., 1967], No. 53886/67. Heading F4T. A torch for flame heating a metal workpiece, e.g. jointing an oil-filled electric cable, welding, brazing, soldering, cutting, is connected through a valve assembly to a source of combustible gas, e.g. acetylene or propane and to a source of fire-extinguishing fluid so that in one operating position of the valve combustible gas only flows through the torch and in another operating position of the valve only fireextinguishing fluid is supplied through the torch. In a preferred embodiment, Fig. 1, the torch comprises a cylindrical body 1 terminating in a burner nozzle 31, a tube 3 for passage of fire-extinghishing fluid secured to and extending alongside body 1, its discharge end 34 encircling the nozzle 31 and having orifices 32 directed towards the same location as the end 33 of the nozzle 31, and a valve housing 4 secured to the body 1 and the tube 3. A plunger 6 is slidable in a bore 7 in the housing 4 and carries valve closure members 23 and 24 co-operating with seatings 21 and 22 in chambers 8 and 9 respectively, provided at either end of bore 7 and separated by an 0-ring seal 11 on the plunger 6. A spring 26 between the member 24 and an end cap 27 closing chamber 9 biases the valve assembly to the position shown in which fuel gas from a supply line 15 may pass through a handle 16 on the housing 4, and through the inlet and outlet ports 14 and 12 respectively of valve 21, 23 to the body 1. Depression of plunger 6 closes the valve 21, 23 and opens valve 22, 24 to permit fire-extinguishing fluid to flow through inlet 18 and outlet 17 to tube 3. In an alternative arrangement, the spring 26 biases the plunger 6 in the opposite manner to give a " dead man's handle " with a normal position allowing flow of fire-extinguishing fluid. Alternatively a spring-loaded ball or button in the torch body or plunger may co-operate with a depression in the other part to enable the plunger to be locked in a position permitting flow of fire-extinguishing fluid. The valve assembly may be located in the supply lines to the torch. The two supply pipes for gas and extinguisher may be replaced by a composite tube having formed therein at least two passages. In another embodiment the torch is of conventional form and the valve is a two-way valve so that either gas or extinguishing fluid pass through the same passage. In operation, a fluid-operated valve in the gas supply line is maintained open by the pressure in the extinguishing fluid supply line Fig. 2 (not shown). The extinguishing fluid may be a gas giving an inert atmosphere, e.g. carbon dioxide, nitrogen, or a flame-inhibiting material, e.g. bromo-chloro-di-fluoro-methane, methyl bromide, chlorobromomethane, freon, carbon tetrachloride, and a cartridge of such fluid may be carried by the torch.

Filed: 1972-11-24
Abstract: 1376480 Semi-conductor devices SIEMENS AG 24 Nov 1972 [3 March 1972] 54484/72 Heading H1K The emitter electrode 5 of a thyristor shorts the emitter region 1 to the base region 2 at a location adjacent a further region 11 of the same conductivity type as the emitter region 1, which region 11 is shorted to the base region 2 by the control electrode 6, and is located between the control electrode 6 and the emitter region 1. In the blocking direction the presence of the region 11 avoids destructive avalanche break-down of the emitter junction 8, while in the conducting direction it ensures that most of the firing current from electrode 6 passes through the emitter region 1 rather than passing directly to the emitter electrode 5. The invention is particularly useful in thyristors having a central relatively low resistivity zone 10 of the second base region 3. There may be a plurality of the regions 11 symmetrically disposed about the circular base electrode 6 and projecting into corresponding recesses in the inner periphery of the annular emitter region 1. The emitter region 1 may be an auxiliary emitter located within a larger annular main emitter region (22), Fig. 5 (not shown). In this case outward projections (18) of the auxiliary emitter region (1), corresponding to the regions (11), extend towards portions of the main emitter region (20) shorted to the base region (2).
