Abstract: 1438801 Calendar timepieces A SCHILD SA 2 Oct 1973 [13 Oct 1972] 45945/73 Heading G3T A calendar watch has concentric day and date indicators 5, 2 driven by respective projections from members 19, 20 mounted on a hub 17 to which is fixed a cam disc 23, the tip 31 of a spring- biased lever 25 riding along the edge of cam 23 so that when it engages a sloping portion 29 of the cam edge it slides therealong to quickly rotate the cam 23 and hub 17 thereby indexing indicators 5, 2, their rotation being stopped by a projection 32 or lever 25 entering a notch 30 in the cam edge thus preventing double-indexing. Member 20 has a further projection 21 and hub 17 is mounted coaxially with a calendar wheel 16 which rotates once per day and which has an  arcuate slot 24 entered by catch 21, so that wheel 16 drives hub 17 when catch 21 engages the end of slot 24. Slot 24 also permits manual calendar correction at any time, including immediately after indexing. The spring 13 biasing the lever 25 is an integral part of an assembly plate 10 which is secured to a bottom plate 1 by screws 11 and which carries a first stud 26 constituting the axis of lever 25 and a second stud 15 constituting the axis of a wheel-and-pinion 14 interposed between the calendar wheel 16 and an hour wheel 3 of the watch movement.

Title: An improved fuel injection unit for internal combustion engines
IPC: F02M47/02
Filed: 1965-11-04
Abstract: 1,055,010. Fuel injectors. PNEUMODYNAMICS CORPORATION. Nov. 4, 1965 [Dec. 2, 1964], No.46810/65. Heading F1B. A fuel injector comprises a valve 34 the end of which slides within a flexible sleeve 62. Fuel under pressure supplied through a flexible tube 66 to the interior of sleeve 62 expands the sleeve forming an annular gap around the valve stem through which it flows to an accumulator space 100. When the pressure in pipe 66 drops, the pressure in space 100 closes sleeve 62 around the valve stem and forces valve 34 off its seat for injection to take place. Tube 66 is protected by a plastics sleeve 68; the tubes 66 for different injectors may be made the same length, any surplus as the distance of the injector from the pump varies being taken up by coiling it in a space 69. The end of the tube 66 is secured to the spigot of member 36 by adhesive and the sleeve 62 is crimped at 64 and secured by adhesive on the spigot 60. The injector body may be enclosed by a jacket 26 to protect it from the cooling water. In a modification a flange 112, Fig. 4 (not shown), on the valve has a conical face 114 which seals the open end of the flexible sleeve 116 at the end of the valve lift to prevent escape of fuel along the sleeve.

In apparatus for copying transparencies, the correct exposure required is assessed by measuring the light transmitted through the transparency by a photo-cell. As shown, the transparency is mounted in a movable frame 15 over an aperture 13 in the top face 12 of a housing 11. Below the aperture is a diffusing screen 14. The photo-cell is enclosed in a case 17 which can slide on rails 16 into and out of position over the aperture (see also Fig.1, not shown). The light source may be a single lamp but is preferably an assembly consisting of a flash tube 21 and a pair of small incandescent lamps 122 see also Fig. 3, not shown). These are carried on a support 19 which can be moved up and down vertical guide rods 23 by means outside the housing 11. This movement can be carried out, using the lamps 22 as a light source, until a predetermined reading is obtained by the photo-cell, as shown by a meter (35, Fig.1, not shown).

Title: Fuel systems for gas turbine engines
Inventor: WARNE EUGENE HAROLD
Filed: 1966-10-28
Abstract: 1,213,974. Gas turbine engine fuel systems. JOSEPH LUCAS (INDUSTRIES) Ltd. Jan.26, 1968 [Oct.28, 1966], No.48429/66. Heading FIG. A gas turbine engine fuel system comprises means defining a main passage for flow of fuel from a fuel pump to the engine, means defining a further relatively restricted passage for flow of fuel from the fuel pump to the engine, control apparatus in association with the further passage to vary the flow therethrough in accordance with changes in engine variables and thus the pressure at the downstream side thereof, and a pressure-responsive device with which both passages communicate, at positions upstream of respective restrictors in the passages and downstream of the control apparatus in the futher passage, the device being arranged to maintain equality of pressure at these positions. Fig. 1 shows a fuel system in which a passage 17 leading to a burner manifold is supplied with fuel by a swash-plate pump 10 via a main passage 14 and a further passage 15 connected in parallel with the main passage. The flow through the passage 15 is controlled by a combined acceleration control and metering device 16. The device 16 is of known type, comprising a throttle valve controlled in accordance with engine variables including compressor pressure conditons, engine speed and jet pipe temperature. The pressure drop across the device 16 is applied via passages 24, 25 to the servo-device 11 of the pump so as to control the pump delivery. The flow through the main passage 14 is controlled so as to bear a constant ratio to the flow through the passage 15, by means of a throttle valve 26 comprising a slidable piston 27 exposed at opposite sides to the pressures upstream of respective restrictions 29, 30 in the two passages, whereby these two pressures are equalized. Thus, the device 16 controls not only the minor flow through the relatively restricted passage 15 but also the major flow through the main passage 14. In a modification, the variable capacity swash-plate pump is replaced by a fixed-displacement jump such as a gear pump. The amount of fuel delivered by this pump in excess of the flow through the passages 14, 15 is in this case returned to the pump inlet by means of a by-pass valve controlled by the pressure drop across the device 16. This by-pass valve may additionally be controlled in accordance with engine speed by means of centrifugal weights. In this case, the device 16 disposed in the passage 15 comprises only a fuel metering portion and not also an acceleration control portion. In addition, the piston actuated throttle valve 26 is replaced by a diaphragm-actuated one.

[Also in Division A4] Treatment for burns or other dermatolergical lesions comprises immersing the patient in a bacteriostatic liquid for a time long enough to permit healing. A silicone fluid is used as this does not cause maceration of the tissues and is water-repellent, the preferred liquid being a dimethylsiloxane. The bath for the treatment comprises a rectangular tank 10 having one outlet 12 at its lowest point and a second outlet 13 controlled by a weir 16. These lead to a circulating pump 20 which passes part of its output through a pipe 22 to inlets 24, to cause turbulence, while the remainder passes through a pipe 23 to a bacterial filter 28, a deodorising tank 28a and a heat exchanger 29, for preventing undesired rise of temperature, and thence to inlets 30 near the upper part of the tank. The filter 28 is formed by depositing a cake of diatomaceous earth on a porous fabric layer through which the liquid passes and this is done by withdrawing part of the liquid through a pipe 41 to make a slurry in a tank 39 and then pumping this through to the filter chamber 28. In the deodoriser the liquid is passed through a perforated receptacle filled with activated charcoal. During treatment the patient is supported on a sling-like frame 31, which may be raised or lowered by hydraulic jacks 32, 33 and the frame may carry subsidiary supporting members mounted on a transverse pivot at the lowest point on the frame so that the shoulders or feet may be raised or lowered. In addition, in a modified form of the tank, see Fig. 2 (not shown) lateral extensions are provided to allow the arms to be extended sideways.
