Abstract: 1,223,106. Processing barrels. ELECTROCHEMICAL DEVELOPMENTS Ltd. April 10, 1968 [May 9, 1967], No.21522/67. Headings C7B and C7E. A processing barrel (e.g. for pickling, cleaning or electrolytic plating) is shown in cross-section in Fig.2. It comprises axially extending panels 11 arranged with adjacent axially extending margins radially spaced apart and connected by wall members forming concave channels 10. When the barrel is rotated anti-clockwise articles within the barrel, such as nuts and bolts, are lifted from a lower region and then dropped from an upper region. With clockwise rotation the articles are not lifted. The barrel is of perforated material such as stainless steel, Monel metal ("Monel" is a Registered Trade Mark) or synthetic plastics material and in use is immersed in the processing liquid. Electrodes (not shown) extend from the barrel's ends. As illustrated in Fig. 1 (not shown) the barrel tapers from one end (2) to the other 3 and has an opening (7) in the end (2) closed by a door (9). Articles are removed from the barrel by inserting a trough through the opening and along the barrel's axis and rotating the barrel anti-clockwise so that articles are lifted and then fall into the trough.

Title: A variable torque internal combustion engine
IPC: F02B69/06
Filed: 1927-08-17
Abstract: 287,774. Seiliger, M. Aug. 17 1927. Regulating delivery bye-passes; stroke, varying. -In order to vary the torque inversely as the speed in engines using liquid-fuel injection, the air and fuel supplies per unit time are maintained constant, so that more air and fuel are supplied per cycle as the speed decreases, and in addition for speeds below half-maximum, the working of the engine is changed over from the four-stroke to the two-stroke cycle. The fuel pump m may be driven by a separate motor to maintain the supply constant, or it may be driven by the engine and have its stroke varied by an adjustable cam y, Fig. 3. A governor n, by opening a bye-pass valve o in the fuel supply, limits the maximum speed at which the engine may run, and the amount of this speed is varied by adjusting the belt and cone-pulley drive q, r for the governor. The stroke of the engine-driven fuel pump x, Fig. 3. is varied so as to maintain a constant supply per unit time by hand or governor adjustment axially of the cam y, which is formed with an incline y<1> for increasing the stroke as the speed decreases with four-stroke working, and with two opposed inclines y<2>, y<3> for increasing the stroke during two-stroke working.

Title: Rotation/translation independent feature extraction means
IPC: G06K9/46
Filed: 1969-04-30
Abstract: 1,216,458. Pattern recognition. BENDIX CORP. 30 April, 1969 [28 May, 1968], 'No. 21983/69. Heading G4R. An orientation-independent pattern feature extractor, for automatic pattern recognition, rotates an image of the pattern on an image slicer input face divided into parallel slices for linearly integrating the light flux incident upon each slice, voltages non-linearly related to the flux incident on each slice being summed and memorized at N predetermined rotational positions during the rotation, the memorized voltages being fed to N electrical adders via an NXN matrix of electrical weights. Each slice feeds the light it receives via optical fibres to a respective photo-cell, the photo-cell outputs being squared then summed. The summer output is routed to respective capacitor memories at particular times in synchronism with the image rotation (which is achieved with a dove prism or 3-prism rotator). Each memory feeds each of a set of further-summers through a respective weighted resistor, each memory using an identical -set of resistors but the connections from the latter to the further summers being cyclically permuted in going from one memory to the next. A maximum selector passes the highest of the further summer outputs to a thresholder and identifies the further summer it came from.
