Title: Device for electrically stunning butchers beasts in particular pigs
IPC: A22B3/06
Filed: 1978-05-16
Abstract: The apparatus has two continuous conveyor belts (1, 2) which operate synchronously with and parallel to one another and are arranged in a V-shape, and has a floor (3) which is inclined downwards in the direction of movement of the belts so that the pigs lose their footing and are clamped tight between the belts (1, 2). Electrodes (5, 6) which extend between the conveyor belts and are pivotable about horizontal shafts (7, 8) are arranged in a frame in such a way that they are able to come into contact with the head at two points, one of which is situated below the other, to permit the flow of a control current. The current pulse to stun the animal is then emitted. The stunning process achieved in this manner is more effective and uniform than manual stunning using hand tongs. <IMAGE>

Title: Improvements in or relating to apparatus for regulating a forced-flow, once-through boiler
Inventor: BACHL HERBERT
IPC: F22B35/10
Filed: 1956-06-27
Abstract: 793,341. Forced-flow steam boilers; controlling superheat. SIEMENS-SCHUCKERTWERKE AKT.-GES. June 27, 1956, No. 19943/56. Classes 123(2) and 123(3) A forced-flow, once-through steam-boiler comprising an evaporating section from which steam flows through successive superheaters 1, 2 to a turbine 4 driving a generator G is regulated under sharplychanging loads by variation of the firing rate and of the settings of the main feedwater valve 9, of a valve E1 which controls the amount of water injected into the boiler tubing at a point e1 between the superheaters 1, 2 and a valve E2 which controls the amount of water inpected at e2 between the evaporating section and the superheater 1. The setting of the valve E2 is controlled according to changes in boiler load, whilst valve E1 is controlled through a regulator device f according to changes in steam temperature measured at points t2, t3 located respectively before and after the superheater 2. If, for example, the demand on the generator G suddenly increases, the main turbine regulator h causes a valve 3 to open to admit more steam to the turbine. Impulses r, x representative of steam pressure variation and generator output respectively are transmitted through a boiler load setting device g to regulating devices, a, b, c which respectively effect appropriate increases in the amounts of air, feedwater and fuel fed to the boiler. To satisfy the demand for extra steam during the time when the increased supply is traversing the evaporating tubes, and thus to avoid a temporary drop in pressure at the boiler outlet, the load setting device g also causes the valve E2 to open further to admit an increased quantity of water to the superheater 1 wherein it evaporates by adsorption of heat from the tube system to supply the extra steam required. The resulting reduction in steam temperature is offset by the closing of the valve E1 to reduce the amount of water injected at the point e1. When the increased quantity of feed- - water has advanced to the injection point e2, a time delay element Z3 cancels the control order to the valve E2 and the boiler operates normally at the higher load.

Title: Automatic cameras
IPC: G03B9/58
Filed: 1964-05-15
Abstract: 1,072,361. Automatic shutter control. COPAL KABUSHIKI KAISHA. May 15, 1964 [May 17, 1963], No.20305/64. Heading G2A. In a camera shutter in which the exposure time is controlled by an electronic circuit including a photo-conductor exposed to the ambient illumination, the diaphragm is opened to a predetermined aperture during the first part of the movement of the shutter release, the remainder of the said movement triggering the exposure; if the illumination is sufficiently bright, the shutter is actuated before the diaphragm has fully opened, and an exposure is made at that aperture. Fig. 1 shows the shutter in the cocked position, Fig. 2 (not shown) being a rear view. Coupled to the release bar 1 is a disc (3), which is itself coupled to two plates 4, 5 having similar but opposed apertures 4a, 5a. Thus when disc (3) is actuated by bar 1, the plates slide in mutually opposite directions, so varying the amount of light allowed to pass through an aperture 2b to the photo-conductor Rx, Fig. 3 (not shown). A ring 10, reading against a scale 9, sets the diaphragm to a desired value. The diaphragm is adjusted by a ring (12), coupled to disc (3) by a lever (6), ring (12) having three coupling pins (12a), (12b), 12c. Clockwise movement of the diaphragm in Fig. 2 is stopped when pin (12b) abuts against a projection (10a) of ring (10). The shutter is cocked by winding a driving disc 22 anticlockwise (Fig.1), the disc being moved clockwise by a spring when the shutter is released. Fig. 3 (not shown) is the controlling circuit, in which two electromagnets M1 and M2 are controlled by the transistor circuit shown. Initially, point A is positive with respect to point B, magnet M2 is energized, and magnet M1 is not. Release lever 17 is freed to rotate clockwise by release bar 1, and, via a lever train, a first shutteractuating disc 19 rotates clockwise to open the shutter. The exposure period is determined by the capacitor (C) (Fig. 3), in circuit with the photo-resistor (Rx). When the polarities of points A and B are reversed after a delay time depending on the amount of light falling on (Rx), magnet M2 is de-energized, so that it no longer attracts a lever 24 which is spring-biased away from it. Through a chain of inter-engaging levers 24, 25, 27, the driving disc 22 is released and rotates a second shutter-actuating disc 21 (coaxial with the first disc 19) to close the shutter blades. If, however, the illumination is so bright that the photo-conductor resistance falls to an extent such that point A becomes negative with respect to point B before the diaphragm has fully opened, the magnet M1 is energized. This attracts a lever 30 which causes a hook 31a at the end of a lever 31 to latch into teeth 14b of a plate 14, the plate being coupled to a diaphragm-adjusting ring (12) by means of a pin 12c. The ring (12) is thus prevented from opening any further. Fig. 4 (not shown), having a corresponding control circuit Fig. 5 (not shown) has a modified arrangement of the plate 14 as associated with magnet M1.
