Patent GB-1051788-A (GB)
IPC: G03B7/081
Abstract: 1,051,788. Camera shutters. AGFA A. G. March 11, 1965 [March 19, 1964], No.10398/65. Addition to 1, 051, 787. Heading G2A. A camera shutter comprises two spring biased blade rings 301, 302 for operating shutter blades 303 and is characterized in that the run down of ring 301 is continuously retarded by an escarpment mechanism 314, 316 and can be stopped to set the maximum aperture opened by the shutter blades by means of a projection 348 on the ring engaging a stop 347 on the aperture setting ring 337 whilst operation of the blade ring 302 can be variably delayed by an electromagnet 330 operating a lever 331 to engage projection 332 on the ring. The electrical circuit is completed by cam 335 engaging contacts 327 when the shutter is tensioned by lever 320 being moved against pin 324. For "bulb" exposures the setting ring 336 is turned to the appropriate point where pin 341 of a lever 342 engages in the wide part 340a of a slot in the setting ring. This allows a stop 354 on the lever to engage a projection 355 on the blade ring 302 to delay closing of the shutter until the tensioning lever 320 is released to allow pin 319 to move the lever 342 away from the ring. In an embodiment the run down of the second blade ring 302 is delayed mechanically by a lever, ratchet wheel and balance wheel arrangement instead of electrically and also the stop 347 is pivoted on the camera and engaged by a cam on the setting ring. In a further embodiment the projection 348 is engaged by a ratchet type lever and a switch in the electrical circuit can be operated, when taking flash exposures, to put a resistor in.parallel with the electromagnet instead of the condenser and resistor.

Abstract: 1,095,533. Electric tachometer. P. GOSSEN & CO. G.m.b.H. March 7, 1966 [Sept. 10, 1965], No.9796/66. Heading G1N. A tachometer for measuring the rotational speed of an I. C. engine comprises a measuring circuit connected in parallel with the make and break device 12, Fig. 2, of the engine, through a self-saturable choke 10 of high permeability and a resistance 11, an indication of the frequency of the voltage pulses across the make and break device and therefore of the ignition speed being given by the measuring circuit. When the ignition is switched on and the device 12 is open, current from the engine battery 14 flows into the measuring circuit, saturating choke 10 and charging a measuring capacitor 5 to a level dependent on current limiting Zener diodes 2, 3. At a time t 1 , the device 12 is closed, the current from the battery is effectively cut off and flows only through the sparking circuit. When this occurs the capacitor 5 discharges exponentially through a resistance 4 and the choke, so that the latter becomes unsaturated, Fig. 5 (not shown). At a subsequent time t 3  when the device 12 opens, sparking takes place and high frequency oscillations occur in the voltage across the device 12, Fig.4 (not shown). These oscillations are blocked by the choke due to its high inductive resistance, thereby protecting the measuring circuit from them. During the time t 3 -t 4 , while the oscillations are gradually dying away, the voltage across the device 12 gradually builds up resulting in the re-saturation of the choke and the re-charging of the capacitor. As this occurs a pulse is transmitted to the measuring circuit where it is detected by a moving coil meter 9. Finally at a subsequent time t 4 , the device 12 is again closed and the cycle of operations is repeated. As the meter 9 has a long time constant, it averages out the constant voltage pulses to give a reading which is indicative of the frequency of the pulses and therefore of the ignition speed.

Abstract: 1,228,449. Vehicle anti-theft device; locks. NISSAN JIDOSHA K.K. 13 Sept., 1968 [23 Sept., 1967; 5 April, 1968], No. 43581/68. Heading B7J. [Also in Divisions E2 and G4] A key-operated steering lock for a vehicle has an associated alarm circuit such that the opening of a vehicle door with the steering not locked, operates an alarm. In Fig. 4, a steering shaft 15 has a sleeve 17 welded on it with a slot 16. A locking bolt 10, engages with this slot by means of a key 56 operating a key cylinder 24 ganged with rotor 44. This rotor is contained within a hollow slider 28 (Fig. 7) and is associated with an engine switch 1. Rotor 44 has a diametric groove 50 along which slides a plunger 49 and a stop 53. Rotation of the rotor moves the slider up and down, at the stop position, the slider being acted on by the peripheral edge of the shoulder of the rotor, hence forcing spring 27 into compression. The slider is held by the key tip 58 engaging with stop 53 and when the key is removed the locking bolt 10 is urged by the spring into the slot 16. Alarm switch 4 is operated by a ball 11 which opens the switch when the ball engages recess 10a of the locking bolt. A further switch 3 (Fig. 3, not shown) closes upon the opening of a car door, thus completing the alarm circuit if the engine and alarm switches are both already closed. Engine switch 48 controls the ignition and start circuits whilst also determining the key positions at which an alarm can be sounded. The alarm may operate only in the garage or stop positions or, Fig. 15 (not shown), in all key positions.

Crates (not shown) are transferred from a vehicle platform 25 to a support 26 below the lower run of an endless conveyer 1. The latter comprises a central endless chain 3 retained in guides 2 and carrying blocks 19 at spaced intervals. The latter support either pushers 7, or cross members 4 which carry crate-engaging hooks 5 at each end. The hooks 5 are gravityurged to engage the crates on the lower run of the conveyer, but automatically fall out of engagement on the upper run. During passage along the latter, the crates are driven by the pushers and are supported on an upper pair of rails 14, 14. Members 28 (Figs. 1 and 3) hold the hooks 5 out of engagement with the crates until the latter reach a restraining device 27. This comprises vertically disposed rubber strips 27, 27 which restrain movement of the leading crate on the platform 26 until it is engaged and positively driven by, the hooks 5. At the opposite end of the conveyer, members 30 hold the hooks 5 in engagement with their associated crate associated until the latter has been brought up to the upper run of the conveyer. The crate is then centred laterally on the supporting rails 14, 14 by rubber blocks 33, 33, carried by frame members 32, 32. Guide members 6 carried by the chain 3 are then able to engage a positioning groove formed in the lower surface of the crate.
