Title: The conversion of a logarithmically dependent measure of a quantity to a linearly dependent measure of that quantity
IPC: H03M1/00
Filed: 1964-07-10
Abstract: 1,072,358. Selective signalling. WARNERLAMBERT PHARMACEUTICAL CO. July 10, 1964 [July 12, 1963], No. 28695/64. Heading G4H. [Also in Division G1] To obtain a quantitive measurement of a physical property of a material a function log (I R /I T ) varying according to the quantity may be measured by a speotrophotometer sensing reference and test samples and impressing the grids of reference and test cathode followers 14, 12 to provide reference and test signals I R , I r  on lines 16, 13 of a bridge circuit 18, which circuit includes a linear potentiometer 17 whereby the relative magnitudes of its two output signals from points 31, 32 can be varied, a detector 34 whereby they can be compared and a motor responsive to the detector 34 to drive the potentiometer to a position to make the outputs equal and so, through eccentric gears 24 between the potentiometer 17 and an indicator 23, to drive the indicator in substantially linear dependence on the quantity to be measured, a scale shift (from ( - 5 to +5) to (0 to 10)) being produced by including amplifiers 36, 37 whose amplification factors are in the ratio of one to the square root of ten. Fixed bridge resistors 26, 27, 28, 29 may be chosen to make the displacement of the potentiometer shaft 21 approximately linear with respect to log (I R /I T ), the eccentric gears 24 making the displacement of the indicator shaft 22 a nearer approximation to linearity and a final calibration of the scale removing any residual non-linearity. The balance position is quickly reached by allowing the reversible motor (43), Fig. 4 (not shown), to drive the potentiometer (17) rapidly through a pin (57) and an abutment (58) in one direction while a friction clutch (53, 54, 56) in a reduction gear train slips; if the balance position is overshot the motor reverses, breaking the forward pin-and-abutment drive connection and driving the potentiometer through the reduction gearing back to the final balance position. In order to record the value of the quantity automatically the indicator shaft may carry a coded plastics disc for co-operation with a group of photo-electric cells controlling relays operating the keys of an adding machine provided with printing mechanism, Figs. 6, 7 (not shown).

Abstract: 711,920. Price-indicating weighing apparatus. KRAUT, sen., W., KRAUT, jun., W., and KRAUT, E., [trading as BIZERBA WAAGENFABRIK W., KRAUT KOMMANDIT-GES.]. Dec. 7, 1951 [Dec. 18. 1950], No. 28798/51. Class 143 [Also in Group XXXIV] An object, which may carry the optical system of a price-indicating weighing- machine, is supported to slide up and down a vertical column 2 while maintaining strict parallelism of a datum line such as the axis of the optical system. The cylindrical column 2 is straddled by a pair of rollers 4, 5 at different levels, carried by a vertical plate 3 to which is secured a strap 21 carrying the reflector 20 of the optical system. This system comprises a mirror 22, a condenser 23, an obiective lens 24, and the reflector 20 giving a visible scale reading from a chart interposed between the lens 24 and the condenser 23. The chart is formed as a disc carrying multiple concentric price scales, and is turned about a horizonal axis, parallel to and above the optical axis, to an angular position determined by the weighed article. These members are carried on the arms 9, 10 of an E-shaped frame 12, the third arm 7 of which is pivoted to the plate 3 on a pin 8 which lies in the optical axis. The frame 12 is pivoted at 11 to a V-shaped member 15, 16 which is itself pivoted to posts 18. In this way, when the plate 3 is raised on the column to set the machine for a particular price per unit weight, the frames 12, 16 swing on their pivots, and the optical axis rises whilst maintaining parallelism with its original direction. The rollers 4, 5 are caused to grip the column by a spring 6 attached at one end to the plate 3 and at the other to the arm 7. The mirror 22 is attached to a bracket 26 secured to a casing rotatable on the condenser 23.

Title: Correcting telegraph repeater
IPC: H04L25/02
Filed: 1969-06-09
Abstract: 1,273,601. Telegraphy. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 9 June, 1969 [12 June, 1968], No. 28968/69. Heading H4P. In a telegraph repeater the received Start- Stop signals are sampled by two bit-rate clock pulse signals, 180 degree phase displaced, and two corresponding telegraph signals are regenerated, one or other signal being passed to the repeater output by gates controlled by the received signal and the clock pulses. In one embodiment, Fig. 1, incoming signals at 1 which have a Stop duration of two bits pass to a shift register A S -A O , controlled by sampling clock pulses T1, and to bi-stable F B , controlled by sampling pulses T2. The oscillator is started by the Stop-Start transition and is stopped when the Start bit reaches A O . It starts to emit pulses T1 after a delay of “ bit and pulses T2 after 1 bit. The regenerated signals G1, G2 have a relative displacement of ¢ bit and pass to gates P1, P2. The received signal also passes to a bi-stable circuit F C , together with pulses T2 and a signal P4 which has a duration of 1¢ bits and which is generated by a monostable MF which is triggered by pulse P3 during the Stop bit and at a preset time after the prior Stop- Start transition. Bi-stable F C  switches to enable gate P2 if a Stop-Start transition occurs during P4, and to enable gate P1 if a Stop bit and a pulse T2 co-exist during P4. As a result, the signal at output 11 has the Start and information bits of the correct duration but the Stop bit varies about the nominal duration. In a second embodiment, Fig. 2 (not shown), bi-stable F B  is fed from cell A S  rather than direct from input 1 as in Fig. 1, and monostable MF is triggered by the occurrence of the Start bit in cell A O . In a modification of Fig. 2, Fig. 4 (not shown), the signal from A O  is fed to MF via gates (12, 13) controlled by the outputs of bi-stable F C  and by T1 and T2. This ensures that no signal at output 11 has a Stop bit length less than 1¢ bits long.

Title: Improvements in electric systems for automatically signalling hits on targets to a distant point
IPC: F41J5/04
Filed: 1934-10-10
Abstract: 432,156. Electric signalling systems. URBAN, K., 1235, U Plzenky, Prague. Oct. 10, 1934, No. 29034. [Class 40 (i)] In an electric signalling system for reproducing at the firing point the hits on a target, the target is divided into a number of areas which are mounted with means for varying the frequency of a current transmitted to the firing point to operate an indicator. As shown in Fig. 2, each section of a recoil target is adapted to operate a spring-controlled plunger 9 which closes contacts 13, 15 in the grid circuit of a valve 20. This circuit contains an electromagnet 18 which co-operates with a tuning fork of characteristic frequency, the fork being associated with an electromagnet 18<1> in the anode circuit so as to produce sustained oscillations which are transmitted through an amplifier to frequency meter 8 at the firing point. The return of the contact 13 is delayed by a dash-pot 19 in order that the signalling current may persist for an appreciable period. Fig. 3 shows a modification employing two valve oscillators 21, 26 adapted to produce heterodyne beats to select a particular glow discharge indicator 28 in response to the selective switching in of a tuning condenser 23 by a relay 24 upon the actuation of a particular part of the target. The constant frequency oscillator 21 may be stabilized by a tuning fork or piezo-electric crystal. Instead of a recoil target, a pierceable target may be employed, selection being accomplished by the bullet which, when piercing the target, makes temporary connection between a common contact sheet and a plurality of insulated sectional sheets. In a further modification a combined pierceable or recoil target may be employed.

Automatic exchange-apparatus. -A squirrel-cage, Fig. 1, the rods of which are insulated, for example by enamelling, except at a helical series of exposed points, can be rotated to connect a fixed pair of incoming wipers to any one of a number of fixed pairs of outgoing wipers. The incoming wipers 5, 6, Fig. 2, make contact respectively with the out-turned and inturned ends of alternate rods 7, 8. The different pairs of outgoing wipers, such as 9, 10, Fig. 3, are disposed at different levels of the cage, the wipers of the series 9 at any moment engaging the same rod 7 as the wiper 5 and the wipers of the series 10 engaging the same rod 8 as the wiper 6. The cage is rotated by power through a friction clutch, either continuously, when hunting for an idle line, or, when serving as a numerical selector, under control of an impulse-operated escapement, which permits it to move through twice the distance between two neighbouring rods at each impulse. When the selector is to be such that connection can be made through any of a number of pairs of incoming wipers, a corresponding number of cages are mounted on the same shaft, as shown in Fig. 4. The power shaft 11, common to a whole frame of selectors, drives frictionally a lay shaft 41, which can be coupled by an electromagnetically-lifted idler wheel 51 to a shaft carrying a bevel gear 49, which drives the seJector shaft 3. An escapement 58, operated by a solenoid 55, co-operates with pins on the bevel-gear 49 to control the rotation of the selector, slip taking place at the idler wheel when the gear 49 is looked. The selector shaft may be in detachable sections, one for each cage. According to the Provisional Specification, the bars 7, 8 may be insulated by rubber sleeves and may protrude through or be laced through holes in the sleeves at the required contact points.

Abstract: 426,770. Continuously casting composite strip. ARNOLD, C., 11, Southampton Buildings, Chancery Lane, London.-(Cleveland Graphite Bronze Co. ; 880, East 72nd Street, Cleveland, Ohio, U.S.A.) Oct. 13, 1934, No. 29377. [Class 83 (i)] A method of making composite bearing metal elements or strips comprises supporting a strip of metal within a cavity in a permanent mould, passing such mould through a chamber having a heating zone, filling out the cavity of the mould with molten bearing metal, and chilling the mould prior to withdrawing it from the chamber. The permanent moulds 4 may be passed continuously from left to right, Fig. 1, through the passage 5 in a heat resisting chamber 1 cross-sectional views of which, Figs. 2, 4 and 7, are numbered similarly to the section lines. The passage 5 at the left, Fig. 1, is made to surround completely three sides of the mould but opens out toward the right to provide clearance spaces 8, 9 through which molten bearing metal flows from the inlet 13 to pre-heat the moulds, this metal passes up through the opening 10 and along the trough 11 from which it is drained by the outlet 14 ; the passage for the moulds is closed at the top by a heat-resisting strip 6 which rests on the top of the moulds. The inlet 13 also supplies metals to the mould cavity which passes through the openings 22, 23 and out through the openings 24 in the top of the mould. At the right of the chamber the moulds are only supported top and bottom, Fig. 7, this enables cooling water to be sprayed against the sides by nozzles 20 ; waste metal which may adhere to the ouside of the moulds is discharged through outlets 25. The moulds are adapted to cast the composite bearing metal in sections of the requisite length, Fig. 12; the metal insert, Fig. 11, which may have flanged or plain edges is of steel and may be given a coating of bearing metal on one or both sides. The insert may be preliminarily prepared to receive the bearing metal such as by being pickled, washed, fluxed and tinned. A passage 38, Fig. 12, in the moulds gives communication between the mould cavity being chilled and the still heated moulds providing extra metal to the chilled mould as the metal therein contracts.
