Abstract: 738,169. Yarn tensioning devices. BRITISH CELANESE, Ltd. Sept. 28, 1953 [Sept. 30. 1952], No. 24449/52. Classes 120(2) and 142(1). A yarn passes between a lower disc 14 and an upper disc 45 which tends to be rotated by the running yarn, the discs having a mating groove and rib 16, 17 so that the tension in the yarn lifts the upper disc ; the yarn engages a pulley 42 on a sleeve 40, causing it to rotate faster than the disc 45 so that a helical groove 48 co-operating with a pin 49 on the disc lifts the disc still further, whereby the greater the tension in the yarn, the less it is increased by the tension device. When the yarn stops moving, it is gripped by the upper disc dropping under its own weight, thereby maintaining tension in the yarn on the output side of the device.

Abstract: 1,062,645. Controlling aircraft. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. June 18, 1964 [June 20, 1963], No. 24605/63. Heading B7G. [Also in Division F2] The selector levers of an aircraft's control surface jacks (15, 16), Fig. 1 (not shown), are linked to pilot-operated cables (21, 22) by links (18, 19) each pivoted to the centre of a compensating beam 35, each end of which is connected via opposite handed bell crank quadrants 29, 30 to one of the cables (21, 22) such that opposite movement of the cables moves the compensating beam 35 bodily to operate the control surfaces whereas similar cable movement on expansion or wing flexing merely pivots beam 35 without inducing flap operation. The outer wing control surface (14) is also operated on opposite cable movement by a cable tensioner (25).

Abstract: 660,748. Automatic temperature control systems. PARSONS & CO., Ltd., C. A., ARKLESS, G. F., and VOYSEY, R. G. June 10, 1949, No. 24670. Class 38 (iv). In a heating system for fluid wherein temperature is maintained constant by a thermostat, part only of which is in thermal contact with the fluid, close control is achieved by the provision of an electric heater, in thermal association with the remainder of the thermostat, the heater being connected to the mains concurrently with the main heater of the fluid. The part of the thermostat in thermal relation with the fluid is journalled in a conduit, while the other part may be disposed in a space containing a medium at a lower temperature than the fluid. The thermostat may be of the type employing two dissimilar metals, or an expansible fluid in a container.

Title: Projection system
Inventor: CORNELL WILLIAM D
IPC: G03B21/00
Filed: 1970-05-21
Abstract: 1299647 Projection system BRUNSWICK CORP 21 May 1970 24750/70 Heading G2J A projection system, for example for displaying bowling scores, comprises a light source 13, a prism 11, means for directing light into the prism and means including a relay lens whose principal axis is inclined to the optical axis for projecting an image therefrom on to a viewing screen 25. To one surface 11a of the prism is secured a plate 12, which may carry on its surface 12a a permanent image of a scoresheet. There is provided means for impressing on this surface the score at a given time, so that light directed into the prism by paraboloidal mirror 14 and condenser lens 15 is reflected by the surface 12a so as to carry the image of the score but not of the impressing means. The plate 12 also serves to protect the prism against damage by such means. It is known that for the prism 11 to produce full depth of field correction with the image i' normal to the exiting rays, the angle B' is related to the angle A' by where X is the refractive index, but that this causes astigmatism in the final image on the screen 25. The angle B' of the prism 11 is therefore made substantially less than the value given by this formula, so that the image is at i, and the projection means is arranged to complete the depth of field correction without introducing astigmatism. Light from the prism is reflected by plane mirrors 16 and 17 and then the relay lens 18, whose principal axis is inclined to the optical axis of the system at this point by an angle equal to half the angle between the image i and the rays leaving the prism, renders the image normal to the system axis. The rays then travel through aperture 27 in lower housing 26, through a field lens 21 in aperture 29 in upper housing 28, and after reflection by mirrors 22 and 23 the image is projected on to the screen 25 by lens 24. The measurements of the system may be chosen so that condenser lens 15 focuses the filament of bulb 13 at the centre of lens 18, and field lens 21 focuses it at the centre of projection lens 24 so that an image of the filament does not appear on the screen.

Title: Potato Dough Extruder
Inventor: ILINES LAURENCE JAMES
IPC: A21C11/16
Filed: 1966-06-03
Abstract: 1,152,747. Extruding potato dough. L. J. ILINES. 3 June, 1966 [8 June, 1965; 15 Dec., 1965], No. 24802/66. Heading B5A. Chips are made by extruding a potato mix from a cylinder 15, supported by a framework 10, 11, 12a and 12b, through orifices 18, 17 in base-plate 10 and cutting the extrudate by reciprocating a frame 41 supporting horizontal wires (44), Fig. 2 (not shown), beneath the baseplate. Extrusion pressure is derived from a manually operated arm 39a via a rack and pinion operated ram 26 and a piston plate 21. To provide chips of equal length, i.e. a similar length of extrudate depending from each orifice prior to each cutting action, the orifices 56, Fig. 7, have widened mouths and the inclined angle decreases from a maximum A at the centre of plate 55 to a minimum B at the periphery of the plate. Furthermore, a preferred crosssectional shape of each orifice 56 is with inwardly bowed sides (57), Fig. 9 (not shown), and rounded corners (56a), it being stated that the cross-section of the extrudate "recovers" from this shape to one which is square. Modifications include the provision of an electric drive 45, 46, Fig. 1, and a geared manual drive (58-66), Figs. 10 and 11 (not shown), which also includes pins (67, 68) on shaft (60) co-operating with an indexing wheel (69) to automatically operate cutter frame (41) at equal time intervals. To facilitate removal of piston plate 21 from container 15 a pressure relief pad (81), Fig. 6 (not shown), e.g. of polyethylene, may be provided. Also the potato mix may be made in the container by initially placing a cover (78) over the orifices. In a second embodiment, Figs. 12 and 13 (not shown), an hydraulic cylinder (87) is employed connected to piston plate (88). An hydraulic pump (90) is actuated manually by means of a bundle (91) and the cylinder is retracted by springs (101) after actuation of a release mechanism (96) by pressing button (98). In this case the cutting device may comprise a resilient plastics sheet placed over die plate (112) and having microscopic holes which enlarge under pressure and contract when pressure is released. A separate piston plate (113) may be used instead of the pressure relief pad (81) of the first embodiment.

The spacers (23) may be filled with materials (24) of various density to balance the blade. The leading and trailing pre-shaped edge sections 21, 22 may be hollow or tubular and are electron beam welded to the hollow section. The root section of each blade may be formed by the thickened part (25), (26) of each plate 17, 18 or by a separate shaped root (25), Fig. 4 (not shown), welded to the hollow section.

A change-over contact assembly comprises a sliding contact element which is disengaged from respective fixed contact elements by at least one fixed cam adjacent the fixed contact element which acts on a follower secured to, or forming part of, the moving contact element to lift the latter before it reaches the end edge of the fixed contact element. As shown, a moving double-blade contact element has one leg 32 in continuous sliding connection with a fixed element 40, and a cam 44 is engaged by a follower 52 extending laterally from the other leg 30 to lift it off a contact surface 42 (extending laterally from a contact element 36) and on to a contact surface 38. A retractive push button switch using this contact arrangement (Figs. 5, 6 and 8, not shown) comprises an insulating cylindrical support (82) having axially extending. grooves (83) in its outer surface in which the fixed contact elements, such as 40, 36 and 38, are retained by an insulating cylindrical sleeve (90) fitted over the support and provided with axially extending slots (91) aligned with the grooves (83) to permit the moving contact elements 30, 32 to engage the fixed contact elements therethrough.
