Title: Folding rule
IPC: G01B3/06
Filed: 1978-05-31
Abstract: In this folding rule, the elastic element, by means of which two adjacent members (1, 2; 4, 5) connected by a bolt (3) are held together secure against rotation in their latched tight position, is arranged in the interior of one member (1, 2), instead of on the outside thereof, as previously. Consequently, only the head (7) of the bolt (3) remains visible on this outside or scale side, with the result that the pattern of the scale is much less impaired. The resilient element can be a leaf spring (6) which is situated in a groove-shaped recess (9) now provided on the inside of the outer cross-sectional part (1); however, it can also be formed by the outer cross-sectional part (1) itself, which is pressed into a cavity (8) when the two members are pivoted by means of the head (7) of the bolt (3). An arrangement with resilient tongues is also conceivable. <IMAGE>

Abstract: 1430953 Averaging UNION CARBIDE CORP 30 May 1973 [31 May 1972] 25806/73 Heading G4A The average value of each signal in a sequence  of binary coded signals repeated 2<SP>n</SP> times is derived by feeding each signal to an adder 116 (Fig. 2) where it is added to the sum of the corresponding signals in each preceding sequence, the adder output being fed to a serial store 110 connected to the adder input, the store being of such length that each stored sum is applied to the adder coincidently with the associated input signal in the next sequence, the final stored sum being shifted by n places to divide the accumulated data by 2<SP>n</SP>. The averaged data may be converted to binary coded decimal form and printed. As described the serial store is a shift register but a delay line or magnetic drum may be used. The apparatus is used for averaging signals from an analogue/digital converter (21, Fig. 1, not shown) receiving its input from a photomultiplier (13) measuring the light absorbence of liquid in cuvettes (9), via a logarithmic amplifier and a peak detector. The cuvettes are located in a ring member (4) fixed to a disc (1) controlling a timing function generator (20) which provides clocking pulses for the circuitry. In the embodiment described n = 3 and counter 100 counts the revolutions of the disc which has 30 cuvettes. The analogue/digital converter encodes to 12 bit binary form, the shift register having a length of 30 Î 15 bits, three 0 bits being added in the most significant position to the output of the converter in a reversible register. After eight revolutions of the disc, counter 118 is enabled by the output of revolution counter 100 to apply three shift pulses to the register 110 to effectively divide by 8 before the data is read out. The system may be used for the determination of glucose in blood serum. Copending Application 25805/73 is referred to.

Title: Improvements in and relating to devices for damping oscillations set up in structural members
IPC: F16F7/10
Filed: 1936-09-23
Abstract: 469,864. Vibrationdampers. JUNKERS FLUGZEUG - UND - MOTORENWERKE AKT.-GES. Sept. 23, 1936, No. 25840. Convention date, Sept. 23, 1935. [Class 108 (iii)] A vibration - damping device for a structural member comprises a deformable member which is mounted on the structural member preferably at the point of maximum vibration thereof so as to have a limited amount of free movement relatively thereto, vibration of the structural member causing the deformable member to strike the structural member or a part fixed thereto, so that the resulting frictional resistance of the deformable member during its deformation damps the vibrations. As shown in Fig. 1, the damping device, which is freely movable vertically in a casing 2 secured to the vibrating member 1, comprises two telescoping sleeves 4, 5, the sleeve 4 being embraced frictionally by an annular spring 8 held in the sleeve 5, and being connected to the sleeve 5 by a spring 6 adapted to resist extension and compression of the device. In operation vibrations are absorbed by the frictional engagement of the sleeve 4 and spring 8. In another form, the invention comprises a casing containing a freely-movable resilient member composed, e.g. of rubber. Fig. 3 shows a construction in which a resilient member 3, secured to an arm 11 pivoted to a plate 9 fixed to the member 1, is adapted to dissipate vibration of the member 1 by impact with the plate 9 and with a stop 12. A similar construction is shown applied to a vertical vibrating member and also mounted beneath a horizontal vibrating member, the arm 11 in the latter case being spring-connected to the plate 9. In another construction, Fig. 6, a resilient ring 3 is loosely mounted within a two-part casing 2 on a vibrating shaft 1. The damping device may also comprise a hollow flexible body containing a granular or very viscous substance such as sand &c. or a syrupy mass.

Title: Circuit for producing an alternating voltage proportioned to the absolute value of a variable input voltage
Inventor: COHEN CHARLES L
IPC: G05B1/02
Filed: 1959-07-28
Abstract: 900,228. Phase-sensitive circuits. ACF. INDUSTRIES Inc. July 28, 1959, No. 25840/59. Class 38 (4). [Also in Group XXXIII] A circuit for converting a variable amplitude A.C. input which may be either in phase or 180 degrees out of phase with a reference into an A.C. output whose amplitude varies with the input amplitude, but is always in phase with the reference consists of a full-wave rectifier bridge gated on alternate half-cycles by the reference voltage. The input signal is applied by a transformer 10 to a full-wave rectifier bridge 13, 14, 15, 16. A pair of equal resistors 25, 26 are connected across the output diagonal AB of the bridge. The output to an amplifier 28 is taken between the centre tap of the transformer 10 and the midpoint 27 of resistors 25, 26. The resistors 25, 26 also form, together with diodes 22, 23 a second bridge having AA as the output diagonal, the input diagonal 24, 27 being connected in series with resistor 29 across a further centre-tapped transformer (unreferenced) connected to the reference voltage source. The centre taps of both transformers are connected to earth. The reference voltage is always greater than the input signal. Thus on alternate half-cycles of the reference voltage, diode 22 passes current through resistors 25 and 29, and diode 23 passes current through resistors 26 and 29. All three resistors being of equal value, there is no resultant output voltage between the point 27 and the transformer centre tap in the absence of an input signal to the first bridge. The conduction of diode 22 blocks diodes 13 and 14 and the conduction of diode 23 blocks diodes 15 and 16. Thus during one half-cycle of the reference voltage, with 13 and 14 blocked, either 15 or 16 conducts to provide a half-wave output pulse of a fixed polarity regardless of the phase of the input signal and conversely on the other half-cycle of the reference. The circuit is stated to simulate rudder drag in an A.C.- operated flight trainer.
