Title: Camera
IPC: G03B17/00
Filed: 1976-12-02
Abstract: 1528426 Camera mechanism FRANKE & HEIDECKE GmbH [trading as ROLLEI-WERKE FRANKE & HEIDECKE] 2 Dec 1976 [17 Feb 1976] 50285/76 Heading G2A A camera has a selector which selects between (a) normal connection between film advance and shutter tensioning, (b) multiple exposure by disabling this connection, and (c) rewind, the camera having a coupling which can be shifted axially to effect said disabling, in which the action of the shutter release displaces the coupling back to its original position. As shown, the selector 30 can be turned so that a nose 37 on a spring-loaded slide 38 engages in one of three recesses 34, 35, 36. In the basic position, which is (a) above, the nose engages in recess 34. On actuating the winding lever 1, a pawl 2 is brought from the rest position of Fig. 2 into engagement with a toothed wheel 4, which is fast with a gear 6. This engages and rotates a gear 7, and hence a gear 18. Gear 18 is mounted slidably on a shaft 23, and is spring-urged into engagement with a pin 19 fixed on the shaft. Thus gear 18 drives shaft 23 and hence a feed sprocket roller 20 fast with the shaft. Gear 6 also has a clutch engagement with a gear 8, which drives via the transmission gear 16, a gear bushing 17, and hence a film take-up spool (not shown). For multiple exposure, the selector 30 is set so that the nose 37 engages in recess 35. This causes a rocker arm 24 to displace the clutch downwards, so that gear 7 is brought out of engagement with gear 6. Gear 7 also disengages a flange 21 to bring gear 18 clear of pin 19, so that the drive to sprocket roller 7 is disabled. The shutter can now be tensioned by means of lever 1 without advancing the film, so that a second exposure may be superimposed on the first by pressing the shutter release 41. At the same time this causes the slide 38 to be retracted, so disengaging nose 37 from recess 35. The parts of the mechanism now return to the initial or "normal" position. For rewind, selector 30 is set so that nose 37 can engage in recess 36. The clutch is displaced again by a smaller amount, which disengages gears 6, 7, but leaves the mechanism free for rewind.

Abstract: 1534700 Valves DANFOSS AS 10 Dec 1975 [16 Dec 1974] 50624/75 Heading F2V [Also in Division F4] In a thermostatic expansion valve 1, e.g. for controlling fluid flow from the condenser to the evaporator of a refrigeration system, a closure member 6, actuated by a diaphragm 14 in a chamber 17 which is connected to a temperature sensor via a capillary 18, is biased to the closed position by a spring 9 and, in use, by the pressure of fluid in the inlet 3 such that fluid flow through the valve is substantially independent of changes in the inlet pressure. As shown, a bellows 19 forms an enclosed chamber 22 separating the valve stem 7 from the diaphragm 14; the chamber 22 being in communication with the inlet 3 via a passage 24 or by the clearance between the valve stem and the guide. A chamber 23, formed between the bellows 19 and the diaphragm 14, can communicate with the outlet 5 or, via a separate inlet (30), Fig. 2, (not shown), with an evaporator outlet, to make the valve substantially independent of outlet pressure.

Title: Magnetic film store
IPC: G11C11/06
Filed: 1965-12-03
Abstract: 1,107,029. Magnetic storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. 3 Dec., 1965 [30 Dec., 1964], No. 51342/65. Heading H3B. [Also in Division H1] A magnetic store comprises two separated magnetic films, one superposed over the other, a non-magnetic conductive circuit interposed between the two films, and a sense conductor passing in succession through a pair of registering apertures formed one in each film. Each storage cell, Fig. 1, and Fig. 2 (not shown), comprises a substrate 12, a first conductive layer 16, a first strip of magnetic material 18, a second electrically conductive layer 20 acting as a word drive line and a second magnetic strip 22, the strips being in the form of strip portions between which there is disposed a circular portion having a diameter greater than the width forming a toroid about an aperture 30. In order to write information into the store a positive word pulse is applied to the word line 20 from a driver 32 to produce a magnetic field in the first and second magnetic strips 18, 22 perpendicular to the direction of flow of word current and a positive or negative bit current, Fig. 3 (not shown), depending on the value of bit to be stored, is passed through the bit/sense line 36 extending through the aligned apertures 30 of the substrate and strips. This latter current produces a magnetic field circumferentially in a clockwise or counterclockwise direction about the apertures in the magnetic strips depending on the bit stored. In a reading operation a word pulse current is applied to the word strip 20 which induces a positive or negative voltage in the bit/sense line 36 depending on whether a 1 or 0 is stored, the value of the word pulse being such as not to cause irreversible flux changes and destruction of the stored information. A plurality of the above cells may be employed in a matrix, Fig. 4. In an alternative arrangement of the strips, the strips may have a uniform width with apertures disposed therein along the length thereof. In order to reduce stray interbit coupling the magnetic material between the circular portions of the cells may be reduced or eliminated.

In an automatic control system for a planetary change-speed gear of the type described in Specification 1,039,600, wherein line pressure for operating ratio establishing clutches and brakes 4 ... 7 is controlled by a main pressure regulator valve 103 subject to throttle variable (TV) pressure modulation and biased by a pressure 158 supplied through a " cut-back " valve 1.09 loaded by output speed responsive governor pressure 164 to reduce line pressure above a predetermined output speed, the cutback valve 109 is additionally loaded in the Low (L) range of a manual selector valve 106 by line pressure 153 which opposes the governor pressure 164 and moves the cut-back valve pool 132 le ft to cut off the supply 158 to the regulator valve 103 which re-establishes unreduced line pressure. In the L-range the selector valve 106 also supplies line pressure 153 to a pressure intensifying valve 186 which acts through a spring 120 on the regulator valve 103 to additionally boost line pressure. Fluid system components.-An engine driven pump 101 supplies pressure liquid to the regulator valve 103 which controls main line pressure 144 and admission of regulated pressure to a torque converter 3 and to front and rear lubricating ducts 180, 184. An engine manifold depression servo 174 controls a primary throttle valve 114 supplying TV pressure 159 to a secondary throttle valve 111. The reduced secondary TV pressure 160 from the valve 111 is fed to the intensifier valve 186 to obtain TV pressure modulation of the regulator valve 103 and to a throttle pressure intensifying valve 115. The valve 115 supplies boosted TV pressure 161 to 1-2 and 2-3 shift valves 107, 108. The valves 107, 108 are automatically shifted in response to opposing boosted TV pressure 161 and output governor pressure 164 which latter is supplied by first and second governor valves 112, 113 rotating with the gear output shaft. A pressurereducing valve 104 is provided between the cut-back valve 109 and regulator loading supply 158. The selector valve 106 has the usual P, R, N, D, L positions. In the low L range a normal 2-1 downshift is permitted but a 1-2 upshift is prevented by supplying additional loading pressure 154 to the 1-2 shift valve 107 in first ratio. A solenoidoperated " kickdown " valve 134 supplies additional loading pressure 156 to both shift valves 107, 108 when the accelerator pedal is over-depressed. Parking brake.-When a selector lever 70, Fig. 2, is moved to the Park P position it acts through a linkage 69, 68, 66, 72, 65 and a cam 64 to move the pawl 61 into engagement with a gear 30 on the gear output shaft. Reference has been directed by the Comptroller to Specification 1,039,600.

IPC: F23D3/40
Filed: 1968-11-06
Abstract: 1,271,370. Fluid fuel burners. BRITISH PETROLEUM CO. Ltd. 7 Oct., 1969 [6 Nov., 1968], No. 52543/68. Heading F4T. A burner for fluid fuels (gas or liquid) comprises a plurality of combustion air tubes 11 which pass through a fuel chamber divided into a fuel inlet zone 14 adapted to distribute fuel across the burner and a fuel outlet zone which is packed with a metal sponge 12 through which, in use, fuel flows into a combustion zone where it burns with air which flows into the combustion zone via the combustion air tubes 11. As shown in Fig. 4, the fuel inlet zone 14 is formed in the spaces between the combustion air tubes 11 in the lower half of the burner and the metal sponge 12, which has a pore size of 0À1-0À5 mm. average diameter, is contained in the spaces between the combustion air tubes 12 in the top half of the burner. In the alternative embodiment, Fig. 7, the fuel inlet zone is packed with a metal sponge 12b which has a pore size of 0À5-2 mm. average diameter and whose resistance to fluid flow is less than that of the metal sponge 12a in the fuel outlet zone. The walls of the fuel chamber and the walls of the combustion air tubes are sealed by impervious coatings 16, 17, 18, 15 applied to the appropriate walls of the two sponges 12a and 12b. The combustion air tubes are all cylindrical with parallel longitudinal axes and the bore of each has a cross-sectional area of 0À1-1À0 cm.<SP>2</SP> where it opens into the combustion zone; the bores account for at least 25%, and preferably at least 50%, of the surface area of the fuel outlet zone adjacent to the combustion zone. When the burner is used with gaseous fuel, the fuel passes through the inlet zone 14 which has a low resistance to gas flow into the metal sponge 12 which has a high resistance to flow which encourages even flow distribution into the combustion zone where the gas burnes with a blue flame with air issuing from the combustion air tubes 11. When the burner is used with liquid fuel, the inlet zone 14 is flooded and the fuel which must partially submerge the metal sponge 12 is drawn up the sponge by capillary action, is vaporized and burns with air from the combustion air tubes 11 in the combustion zone; the thermal conductivity of the metal sponge 12 assists in this vaporization. The rate of fuel flow may be adjusted by control mechanisms. The burner may include the provision of one or more pilot tubes. Further, any tendency for the burner to burn fuel rich at its outer periphery may be counted by the provision of a metal plate therearound or as illustrated in Fig. 5 (not shown) by the provision of extra combustion air tubes (21) in the vicinity of the outer periphery. Reference has been directed by the Comptroller to Specification 1,227,524.
