Title: Lens diaphragm adjustment
IPC: G03B9/07
Filed: 1955-02-07
Abstract: 765,309. Lens mounts; photographic cameras. OPTISCHE WERKE C. A. STEINHEIL SOHNE GES. Feb. 7, 1955 [March 4, 1954], No. 3600/55. Classes 97(1) and 98(1) A camera having helical lens focusing and an iris diaphragm is provided with a diaphragm adjusting device having an abutment adjustable in the path of a moving part of the diaphragm for presetting the aperture, and a drive transmission mechanism including a shaft parallel to the axis of the lens mounting and contained in the mounting and including a yielding coupling, the transmission mechanism extending from the shutter release lever to the movable part of the diaphragm in all positions of the focusing means. As shown, the drive from the shutter release lever moves pin 6 on diaphragm adjusting ring 5 into contact with a stop 4 positioned by the pre-setting ring 2. Forked lug 42 on ring 28 engages pin 6 and the ring is driven by a pinion 26 on shaft 23. The lost motion between lever 15 and toothed segment 19, when the rotation of shaft 23 is prevented by the engagement of pin 6 with stop 4, is taken up by twisting helical spring 18 about pivot 17. Pinions 21, 22 and 24 provide a drive transmission to shaft 23 having a step-up ratio. The shutter is operated when plunger 35 actuated by arm 30 on lever 15 strikes trigger 36. Focusing is effected by ring 38 through interior and exterior screw-threads 9 and 10 and lug 13 slides in groove 12 so that the objective 1 does not turn, the length of pinion 22 being such that the transmission between it and pinion 24 is maintained in all focusing positions. Alternatively, shaft 23 may be telescopic. The objective 1 is secured by ring 41.

Abstract: 562,664. Controlling ; spray carburetters. FJELD, K. T. March 5, 1943, No. 3617. [Classes 7 (iii) and 7 (vi)] Fuel supply to a nozzle 18 in the induction manifold is controlled by a valve 17 actuated conjointly through a lever 21 and cam 12 by a means such as a centrifugal governor (not shown) which displaces the cam axially and a capsule 24 which rotates the cam through a , rack 11 and pinion 10 and is enclosed in a casing 22 communicating with the induction manifold by a pipe 23, the capsule containing a second capsule 31 having its interior open to the atmosphere -or to exhaust back pressure, the capsule in this latter case having a size in relation to the outer capsule 24 substantially that of the compression ratio of the engine. A pipe coil 30 in the capsule 24 and communicating with the manifold may effect a temperature correction. The cam 12 and valve 17 may be replaced by a sleeve valve having axial and rotational movements or by two concentric cylinders, one actuated by the speed governor and'the other by the bellows. The device may be applied to cylinders receiving fuel by direct injection.

Abstract: 1422752 Laminating apparatus and method ASAHI GLASS CO Ltd 25 Jan 1974 [25 Jan 1973] 03689/74 Heading B5N An apparatus for effecting preliminary bonding of assemblies 10 each comprising a plurality of glass plates with an interlayer of bonding material between the or each two adjacent plates, comprises a driven conveyer 41 carrying a plurality of durable bags 1, means arranged at a loading station 40 adjacent one end of the conveyer for loading an assembly into each bag, means for closing each bag after loading, means for evacuating each bag after closing, means arranged at an unloading station 53 adjacent the other end of the conveyer and downstream from the loading station for opening each bag arriving at the unloading station, means arranged at the unloading station for unloading the assembly from the open bag, and heating means disposed between the ends of the conveyer for heating each bag and the assembly loaded therein during passage of the bag from the loading to the unloading station. In the drawings, the bag 1, made of a flexible, airtight sheet material, has loops 4 through which a rod 6 is inserted, the rod having a greater length than the width of the bag opening and sewing to keep the bag closed. The conveyer 41 carries a plurality of posts 42, to each respective pair of which a bag is mounted by holders 15. In operation of the apparatus, as a bag 1 moves anti-clockwise through the loading station 40, a vertically and horizontally movable hook 50 moves in to engage the projecting end of rod 6 and gradually lifts the rod to open the bag. As the posts 42 reach a horizontal position, conveyer 41 is optionally stopped and the bag is loaded with an assembly 10 by intermittently operated loading conveyer 22 mounted on fork 21 which is traversable on wheels 24 to and from the bag. When away from the bag, conveyer 22 is adjacent feed conveyer 31 along which an assembly 10 is fed on to conveyer 22 which traverses to the left and enters the bag. Conveyer 22 is then operated to load the assembly into the bag, conveyer 41 then being restarted, disengaging rod 6 from hook 50 and closing the bag. A plurality of vacuum pumps 43 are mounted on the conveyer 41 and are connected to the ports 8 of the bags. 1. After each bag in turn is evacuated, the pump 43 is disconnected from the bag and the vacuum established in the bag is maintained by auxiliary vacuum pump 44 connected to the auxiliary port of the bag. The conveyer 41 transports the evacuated bags through a heating chamber 51, via a cooling device 52 and on to unloading station 53 at which hook 54 engages with and lifts rod 6 to open the bag and destroy the vacuum, the means for unloading being similar to the loading means.

Abstract: 1375593 Information retrieval E FUJIMURA 27 Jan 1972 3908/72 Addition to 1197429 Headings G4A and G4C The information retrieval system of the Specification 1,197,429 is modified in that random access memory 901 is accessed by addresses defined by a single co-ordinate z. An inquiry data code I q , representing, in the embodiment described, data relating to a telephone subscriber whose number is required, is initially compared in comparator 912 with the contents K 1  of the memory 901 at address z = 1, these contents being read out together with a column number n representing the address in the main file at which telephone numbers associated with the contents K 1  are stored. In dependence on whether I q  is less than or greater than K 1  the next address is derived from either calculator 904 or 905 forming 2z and 2z + 1 respectively so that new contents K2 or K3 are read out for comparison. At equality of I q  and K z  an OR gate 909 is enabled to read out the associated address n to access the main file. If, after the largest value of z has been read out, I q  is greater than K z  a generator 910 adds 1 to the number n read out from the register 901 so that the main file is accessed at the address n + 1.

Abstract: 1492721 Hydraulic shock absorbers A G BLAZQUEZ 4 Feb 1976 [22 Feb 1975 18 Dec 1975] 04298/76 Heading F2S In an hydraulic shock absorber, Fig. 1, oil flows from a cylinder 7 containing a piston (not shown) to an oil reservoir outside the cylinder through passages 18, 19 and past a one-way valve member 17 unless an electromagnet 3 is de-energized causing a member 1 to be released to block access to the passages 18, 19 whereby the oil is forced to flow through passages 9-15 and past a one-way valve member 14 which is set to open at a higher pressure than the valve member 17, the damping characteristic of the shock absorber thus being altered. In the Fig. 1 embodiment the member 1 is urged into blocking relationship with the passages 18, 19 by a spring 2 when the electromagnet 3 is de-energized. The valve member 14 is biased into its closed condition by a spring 11  bearing against a nut 8 secured to a stud 10 to which the valve member 14 is attached. The spring 11 also biases a valve member 12 to close passages 13, which passages serve for return of oil from the reservoir to the cylinder 7. In the modified embodiment shown in Fig. 3 oil flows to the reservoir through ducts 30, 32 and passages 28 closed by a one-way valve member 35 unless, as shown, the electromagnet 3 is deenergized so that a member 27 blocks the passages 28 and the oil is forced to flow through passages 29 closed not only by the valve member 35 but also by a further member 36. Oil is returned to the cylinder 7 through passages 32 and a one-way valve member 33.
