Title: Device for automatically controlling the exposure of a camera
IPC: G03B7/28
Filed: 1976-07-12
Abstract: 1531888 Exposure control in cameras KONISHIROKU PHOTO INDUSTRY CO Ltd 12 July 1976 [21 July 1975] 28969/76 Heading G2A A camera has an array of photodiodes PD 1  PD 2  ... PDn located in or near the image plane, means for determining the maximum, minimum and average logarithmic outputs and means for controlling exposure time or aperture in dependance on one of said outputs. As shown, the photodiode outputs are logarithmically amplified to provide signals P 1 , P 2 ...P n . Circuits PH, VH and MH respectively store P max , P min  and P av  and amplifiers OP 1 , OP 2  respectively calculate P max -P min  and (P max + P min )/2. A comparator CP1 compares P max - P min  with a reference value #, and the following possibilities arise:  (i) P max -P min  # #. This means the speed of signals P 1  ... P n  is small, so a switch AS 3  is turned on and the signal P av  is used to control exposure. (ii) P max -P min  > #. This means that the spread is large and is provided by a light or dark subject against a dark or light background. To determine the nature of the background, a second comparator CP2 compares (P max  + P min )/2 with P av . If P av  is the smaller, the background is dark, a switch AS, is turned on and the signal P max  is used to control exposure. If P av  is the larger, switch AS2 is turned on and the signal P min  is used.

Title: Improvements in or relating to electric watthour meters
IPC: G01R11/36
Filed: 1959-08-25
Abstract: 921,357. Induction type supply meters. SANGAMO WESTON Ltd. Aug. 25, 1959 [Aug. 29, 1958], No. 29083/59. Class 37. In an electric watt-hour meter having a voltage electromagnet 2, 3, Fig. 1, and a current electromagnet 4, 5, flux lag compensating arrangements include a lag-band 7, the reactance of which is adjustable, mounted on the voltage electromagnet. The rectangular lag-band 8, 9, 10, Fig. 3, is anchored to the voltage leg 2, by a bolt 13 and a clamp-plate 14, and spaced from the laminations 11 by an insulator 15. Adjustment of the reactance is by the movement of barrels 27a, 27b within jaws of an iron member 19 which encircles side 9 of the lag-band, an insulator 20 being included within the jaws. The jaws 21 may be equally spaced, and the barrel portions staggered relative to the jaws such that each engages its respective jaw-parts to an extent different from the others. The manner in which phase compensation is effected is described with reference to equivalent circuits, Figs. 6 and 8 (not shown) and vector diagrams 7, 9, 10, 11 (not shown). A figure-eight loop 29 wound around the current electromagnets causes the current flux to lag the current, and is dimensioned to effect coarse compensation for excessive lag of the voltage flux.

[Class 73] A machine for applying adhesive binding strip to the edges and margins of sheet material, such as shoe insoles, comprises a fold forming device for binding the strip around the edge and intermittent means for feeding the work and pressing the bent over margins against the opposite faces. The machine is similar in general construction to. the edge folding machine described in Specification 208,217, [Class 42 (i)], and comprises a fixed frame plate 32, Fig. 9, formed with a groove for housing a slide 38 having a guide-way for the binding strip. The strip is held against backward movement by a detent 42 pivoted to the side which is furnished with a vertically adjustable, undercut block 54 and a thin plate 62 for taking different widths of strip. The folding-device, formed at one end of the frame plate 32 comprises upper and lower fingers 72, 74, and an abutment roll 76 which engages the edge of the work. The work is placed between gripping-members 86, 88, Fig. 10, having bevelled corners 90 and furnished with ribs 95, 97 which urge the work inwards towards the folding-device. The lower member 88 is mounted on the frame plate 32, the upper member 86 being carried on an arm of a bell-crank 96, Fig. 6, located in a groove in the frame plate 32 and operated to lift the upper member for introducing a piece of work by a treadleactuated link 106. The lever 96 also carries a deflector 130 the lower edge of which rests against the partially folded margin of the strip when the work is thin. The work is fed by mechanism similar to that of the Specification referred to and comprising an anvil 142 and a hammer 140 having a tiltable face plate. The former is mounted on an arm 144 clamped to a hollow shaft 146. The hammer arm 148 is pivoted to the anvil arm and is connected to a rod 152 passing through the hollow shaft 146. The rod 152 is oscillated axially to operate the hammer by a cam 182, Fig, 1, on a driven shaft 184 through a lever 186, link 188 and two pivoted arms 190, 192 connected by a yielding link 196. The arm 192 engages the end of the rod through a spring 200. The anvil arm 144 is oscillated to feed the work by a second cam 202 through a lever 204, rockshaft 206, link 208 and an arm 210 on the hollow shaft 146. The strip is severed by a knife 230 carried by an arm 232 operated by an arm 234, Fig. 6, connected by a pin 236 with the slide 38 so as to be operated therewith. The slide and knife are actuated by a treadle operating a rod 274 through a bellcrank 276, 278 and rod 286. The binding strip 40 is fed from a reel 322, Fig. 12, an adhesive strip 300 being fed from a reel 330 ; a separator or carrier strip for the adhesive strip is wound on to pick-up roll 350 carried by an arm 354 pivoted to an arm 356 clamped to a post on which the reel 330 is mounted.

Title: Process for the production of egg products
Inventor: SECK WILLI PHILIPP GUSTAV
IPC: A23J1/08
Filed: 1953-10-22
Abstract: Egg material such as fresh, preserved or dried whole egg or egg yolk, is extracted at a temperature not exceeding 50 DEG  C. with an organic solvent, e.g. ether or a light petroleum fraction, capable of dissolving fats and egg yolk oils and containing up to 5 per cent water by weight and the insoluble residue is separated from the resulting solution which may be treated to recover the fats and oils extracted.  The solvent in the case of dried egg material preferably contains 1 to 2 per cent water.  The egg material prior to extraction or the residue may be mixed with proteins not derived from egg without impairing the foaming qualities. According to an example, 100 kg. whole egg powder is stirred for 30 minutes with 150 l. petroleum ether and 3 l. water at 20 DEG  C., the mixture is then allowed to settle and the solvent removed by decantation.  125 l. petroleum ether with 1.5 l. water is added, stirred at room temperature for 15 minutes, allowed to settle and the solvent decanted.  After a third extraction using 125 l. petroleum ether and 1 l. water and decantion of the solvent, the contents of the extractor are heated under agitation to about 50 DEG  C. and the residual solvent is removed from the egg powder under reduced pressure.

Abstract: 536,295. Regulating; pumps. BUCHI, A. Nov. 6, 1939, No. 29465. Convention date, Sept. 1. [Classes 7 (ii) and 7 (vi)] In an engine having scavenging-air supplied by an exhaust-turbine driven blower 9 to a passage 14, the admission of the scavenging- air to the passage 24 leading to the usual inlet valve 25 is controlled by a separate valve 23 connected to a diaphragm 27, which is acted on at the left-hand side by the pressure of the scavenging-air and at the right-hand side by the pressure of the exhaust or the cylinder gases communicated by a pipe 35. Hand adjustment of the valve 23 is obtained by means of a screw 37 or a lever. The blower also supplies air to the carburetter 16, the mixture from which is controlled by a spring-closed valve 42. The fuel and the charging-air may be supplied by a separate engine-driven blower. In a gas engine, an engine-driven blower either,supplies air to the gas generator, or forces gas from the generator into the passage leading to the inlet valve. Flap check valves may be provided in both the charging-air and gas inlet passages, and both may also have controlling throttle valves. One separate scavenging-air valve may supply several cylinders. The invention may also be applied to liquid-fuel injection engines.
