Abstract: 219,012. Broussouse, F. L. July 12, 1923, [Convention date]. Laminar springs. - The oscillations of a laminar spring are damped by friction which is produced in the spring by means of strong tension created in parts of the laminae by forming them at some point in their length with a curvature independent of the curvature of the principal part of the laminae. The ends 5 of the subsidiary laminae 3 are given a curvature opposite to the main curvature of the laminae as shown in the left-hand side of Fig. 1, and are then clamped to the adjacent lamina by straps 7 as shown on the right-hand side of that Figure. The straps may comprise upper and lower members 11, 10, Fig. 4, welded or otherwise secured together, the upper member 11 carrying an adjusting screw by which the tension of the spring may be regulated. Instead of bending the end of the laminae outwards, they may be bent inwards to a curvature greater than that of the main portions of laminae.

Filed: 1962-05-04
Abstract: 942,219. Digital electrical calculating apparatus. MULLARD Ltd. May 4,1962, No. 17243/62. Heading G4A. By gating output pulses on a selective basis from the stages of a cascade counter and stopping the input when a further counter has attained a predetermined state various arithmetical processes may be effected. The non- carry pulses from the stages of a cascade scaler Zf, Fig. 1, are connected to X gates which are set to represent a multiplicand X<SP>1</SP>. A multiplier Z<SP>1</SP> is set up on a counter Z fed by the output of Zf. When Z reaches the predetermined count it cuts off the input at S and the number registered in A is the product. Division is effected in Fig. 2 where A controls S, the answer Z<SP>1</SP> being equal to A<SP>1</SP>/X<SP>1</SP>.   The operation A<SP>1</SP> = X<SP>1</SP>/Y<SP>1</SP>B<SP>1</SP> can be effected by the circuit of Fig. 3. Square root. The output of scaler Zf is divided by 2 and applied to Xs which is arranged in reverse order. The first cycle of Zf produces no outputs since all the Xg gates are at 0. Successive cycles of Zf will cause the application to counter A of 1,3, 5, 7 &c. pulses. The sum at any point of this series is a square so that if a number A<SP>1</SP> is set up in counter A gate S is operated when Xs carries its square root. A modification (Fig. 8, not shown) computes wages in sterling.

Filed: 1929-06-06
Abstract: 334,930. Kamdron, R. J., and Stavrakov, G. A. Nov. 2, 1928, [Convention date]. Ship's course signals.-In apparatus for signalling ships' courses wherein the magnitude of the interval between two similar sound signals (or two electric impulses) is used to denote the angle to be signalled, means are provided for accurately determining both this interval and the actual duration of the signal. The transmitting device is controlled by setting a pointer 18 on a compass card 45. This actuates through a pinion 16 a rack 14 whereby a friction disc 13 is moved along a cone 19 to a position which results in the core spindle 22 being driven from a motor 3 at a particular speed corresponding to the position of the pointer 18. A pin 24 on a disc 23 secured to the spindle 22 is thus caused periodically to lift a switch blade 29 from the position 40 to the position 41 so as to release its rack end 28 from an eccentric pinion 34 and restore the parts to the position indicated by full lines. In this position a pinion 36 driven at a constant speed engages the rack 28 and draws the bar 29 through a pivoted guide until its end 37 engages the bevelled end 38 of a member 42 positioned by a knob 44 so as to give the desired signal duration, the switch 30 remaining closed during this period. The switch may control a solenoid actuating a whistle. A change-speed gear 7 - - 10 is interposed between the motor 3 and friction drive 13, 19. Blank intervals of thirty and sixty seconds may be added to the interval between successive signals for fast and slow moving vessels respectively. Fig. 3 shows the dial for interpreting the received signals. A time dial 46 providing an entire circle for one minute is used in connection with the usual stop, recording dial and fly-back mechanism. Concentric with this is the usual compass card 47, which is surrounded by a complete circle divided into 360 degrees of angular movement, while an outer semi-circle 49 is also divided into 360 degrees. Determination of distance may be effected by producing simultaneously a wireless and a sound signal and noting with an ordinarys' ships chronograph the time lag between the two signals.

Abstract: 1,014,602. Selective signalling. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 24, 1962 [May 15, 1961], No. 17603/61. Heading G4H. In a digital-to-analogue converter using a Shannon-Rack decoder the digital signals from a number of locations are combined prior to feeding the decoder. In the embodiment described, there are seven inputs, IN1-IN7, each comprising a serial five-unit binary number, the least significant digit arriving first. The word elements are gated to current generators CG1-CG7 which give a unit current if the corresponding input is in its one state. The currents are combined and used to trigger a Shannon-Rack form of decoder which, after all seven five-unit signals have been received, gives an output dependent on the sum of the input signals. This output is stored in a " positive " store. Negative numbers are indicated by the addition of a sign bit to the inverse of the number. Each sign bit causes a signal weighted thirty-one units to be added to a " negative " store. To obtain the resultant analogue signal the contents of the stores are added. If required, the individual inputs can be weighted by weighting the generators CG and the thirty-one-unit generators.
