Patent GB-880164-A (GB)
Title: Electrically operated apparatus for remote measuring
IPC: G01R17/08
Filed: 1959-08-24
Abstract: 880,164. Remote measuring-apparatus. FOXBORO CO. Aug. 24, 1959 [Sept. 12, 1958], No. 28927/59. Class 40(1). [Also in Group XL (c)] Signalling-apparatus attached via a line to a remote receiver comprises a transistor oscillator, a transducer for varying the amplitude of the oscillations in accordance with a physical variable, and a transistor amplifier A.C. coupled to the oscillator so that the average current flowing in the transistors is a measure of the value of the variable, the remote receiver containing the sole source of electrical energy for the apparatus and being connected to the remainder of the circuit only by a two-wire line. In the Figure a transistor 22 oscillates by virtue of the transformer coupling between its base and collector. The mutual inductance between the primary and secondary windings of the transformer is altered by a movable member 54 which is displaceable by a force representing a physical variable such as temperature or pressure. The transistor receives a constant bias from a Zener diode 42 and associated resistors so that the amplitude of oscillation is determined by the transformer coupling factor and hence by the value of the variable. The oscillations are passed on via a coupling capacitor 56 and tank circuit 58 to a Class B transistor amplifier 64, whose average collector current is thus proportional to the value of the variable. Linearity is improved by negative feedback through the circuit 84, 86, and in addition the transistor current energizes a motor 80 which acts mechanically on the member 54 and tends to restore it to its original position. Temperature compensation for transistor 22 is provided by a resistor 50. Transistor 64 needs no temperature compensation as the resistance of the inductor 59 is low. Diodes 48 and 70 prevent harmful reverse currents if the amplitude of oscillation becomes excessive. The transistor current is taken by a line 14 to a remote receiver which includes a meter or recorder 16 and the power supply 20. A capacitor 74 and filter circuit 78 keep the oscillations out of the line and prevents stray pick-up on the line from affecting the transistors.

Title: Improvements relating to fuel-injection arrangements for internal combustion engines
IPC: F02M57/02
Filed: 1951-12-10
Abstract: 714,610. Fuel-injection pumps. DAIMLERBENZ AKT.-GES. Dec. 10, 1951 [Dec. 8, 1950], No. 28938/51. Class 102, (1). [Also in Group XXVII] In a fuel injection unit comprising a coaxially arranged pump 14 and injector nozzle 17, the communication between the pump chamber 39 and a nozzle passage or space 40 controlled by a nozzle valve 43 is controlled by a spring plate 56 abutting against the end wall of the pump chamber. The pump body 10 has an extension 18 with fuel connections 19, 20, Fig. 2, leading to fuel delivery and return passages 25, 26, formed in the cylinder 13 and connected to the pump suction and spill ports 27, 28. The return passage 26 is also connected to the valve spring chamber 44 for removing the fuel leaking past the valve 43 where lift is limited by the valve spring abutment disc 15. The top edge 48 of the cylinder 13 is conical and engages a similarly shaped packing ring 47. A rivet 54 enters a slot 55 in the pump-actuating tappet 30 to prevent it falling out and also secures in position a flanged metal sheet 53 whose edges 51, 52, Fig. 2, are bent over to lock the screw connection nuts of the pipes 19, 20.

Title: Improvements in or relating to sound recording
IPC: G11B7/24
Filed: 1927-10-31
Abstract: 304,848. Mittell, B. E. G., Whitaker, A., and Gramophone Co., Ltd. Oct. 31, 1927. Optical records and apparatus.-Sound is recorded on transparent material such as celluloid by impressing by a smooth pointed stylus without removing any material, and such record is reproduced or duplicated by optical-electric means. If the blank is supported on a rigid support, an upstanding ridge is formed on each side of the sound groove, but if supported on a yielding support, the stylus depresses the blank below the trace into the support to form a bulge. Figs. 3 and 8 show means for reproducing a record 4 formed by depressing the trace into the support so as to form a bulge 6 on the back of the blank. The face of the blank is flooded with celluloid solution to fil up the trace, and the record if of disc form is rotated and traversed so that a parallel beam of light is 'directed through the bufge 6 and is focussed thereby on to, and transversely of, a slit 7 in a plate 8. The focussed beam which moves lengthwise of the slit 7 in accordance with the formation of the bulge 6 passes through a neutral tinted wedge 9, preferablv associated with a plain wedge 11 and falls with varying effect due. to the wedge, 9 on a photoelectric cell 10 which operates a sound emitter or an electromagnetic recorder for making a record. In reproducing a record with upstanding ridges on each side of the trace us produced by recording on a blank on a rigid support, the beam which is spread by the concave form of the trace is directed through a lens to focus it on the slit, and polarizers may be arranged in the path of the beam in front of and behind the slotted plate. Black lines may be produced on the record on each side of the trace by applying ink: this will not Bow into the polished indented trace, and a groove may be depressed between successive traces to limit the flow of the black lines in the other direction. A matt surface record facilitates the application of the black lines.

Title: Improvements in or relating to the prevention and elimination of marine fouling on ships' hulls and other marine structures
Inventor: TURNER ROY VICTOR
IPC: C23F13/02
Filed: 1965-07-08
Abstract: 1,147,754. Preventing fouling of marine structures; electrolysis; alloys. VICKERS Ltd. and CATHODIC & ELECTROLYTIC ENGS. CO. Ltd. July 6, 1966 [July 8, 1965], No.29085/65. Headings C7A, C7B and C7E. Fouling of a surface of a marine structure is prevented or eliminated by treating the surface with water electrolyzed using an anode and cathode electrically insulated from the surface, the anode providing during electrolysis ions of materials toxic to marine growths such as algae, bacteriological slime, mussels, barnacles or other animal growth, and comprising by weight at least “% As, ¢% Sb, or in the case of both arsenic and antimony together “% of each of As and Sb. The bulk of the anode may be of Cu, Fe or Al. For anodes of Cu, the toxic metal content by weight is “ to 2% As, ¢ to 6% Sb, or “ to 2% As together with ¢ to 3% Sb. For anodes of Fe, the toxic metal content by weight is “ to 2% As, ¢ to 6% Sb, or “ to 2% As together with ¢ to 4% Sb. For anodes of Al, the toxic metal content by weight is “ to 3% As, ¢ to 10% Sb, or “ to 2% As together with ¢ to 6% Sb. Typically there may be used in combination a Cu-As anode and an Al anode insulated from each other and the current to each separately controlled. If desired the two anodes may be in the form of a unitary structure but insulated from each other. Electrolysis e.g. of seawater may be effected ina container remote from the surface to be protected or in the medium in which the surface to be protected is immersed, the electrodes being disposed to ensure a passage of the toxic ions over the surface to be protected. If a separate container is used for electrolysis the container may form the cathode so the sea water electrolyzed may be heated. Examples are given of preventing fouling of ship hulls.

The cylinder, pump and valve assembly is mounted between front and rear plates joining the upper ends of the press columns. Specification 766,050 is referred to.
Patent GB-1177608-A (GB)
Title: Apparatus for Performing Division.
IPC: G06F7/535
Filed: 1968-06-20
Abstract: 1,177,608. Dividers; data storage. INTERNATIONAL BUSINESS MACHINES CORP 20 June, 1968 [19 July, 1967], No. 29364/68. Headings G4A and G4C. Division of a multi-order dividend by a predetermined divisor is done by concurrently generating a plurality of intermediate remainders relating to respective orders, combining each dividend order with the next higher order intermediate remainder and dividing the result by the predetermined divisor. Figs. 12A, 12B show division of an octal number by a fixed divisor equal to 3. Each quotient digit is generated in a respective circuit 130, 132 which divides its input by 3 and discards the remainder. In the case of the highest order digit, this input is the highest order dividend digit (circuit 130) but in the other cases (circuits 132) it is a two-digit octal number formed by the corresponding dividend digit (as low-order digit) concatenated with a one-digit intermediate remainder obtained from higher order dividend digits as shown using circuits 134, 126, 128. Each circuit 134 casts out threes from a corresponding dividend digit. Each circuit 126 subtracts its left input from its upper input and casts out threes from the result (i.e. is a modulo-3 subtractor), and each circuit 128 adds its two inputs and casts out threes from the result (i.e. is a modulo-3 adder). Each octal digit is binary-coded so the dividend is also binary. Similar circuits are described for a radix 10, divisor 7 division, radix 8, divisor 7, radix 10, divisor 5, and radix 16, divisor 5 (the 16 is binary-coded so the dividend is also binary radix). Each circuit corresponding to 126, 128 in effect multiplies its left input by (R modulo D)<SP>Y</SP> modulo D, the least positive or negative value being used, where D is the divisor, R the radix and Y the number of orders the input has traversed from its generation point. The resulting product is added to the upper input and the result, modulo the divisor, is the circuit output. In some embodiments, the quantity "R modulo D" is one in which case the multiplication stage is dispensed with, or even zero in which case circuits corresponding to 126, 128 are completely absent. The above embodiments may be preceded by a shift register permitting a preliminary further division by a power of 2 by shifting. Data storage.-In a memory system having a plurality of data words per memory word, the divider above may be used to divide the data word address, the quotient being used to address the memory word and the remainder to select the data word from the memory word.
