Abstract: 1,001,915. Frequency generating circuits. COMMUNICATIONS PATENTS Ltd. March 26, 1964, No. 12848/64. Heading H3F. Apparatus for producing at least two frequency stabilized oscillations comprises a source 12, Fig. 1, of harmonics of stable frequency, a plurality of filters 13-23 each adapted to pass a different one of the said harmonics, and switching means 43; 44 for selecting at least two of the harmonics and supplying corresponding output terminals 46, 49 respectively, one of which, i.e. 49, is supplied via a frequency divider 48, the ratio of division in which is greater than the frequency ratio between the highest and lowest of the harmonic frequencies passed by the filters. As shown, source 12 is driven from a crystal-controlled oscillator 10 via frequencydivider 11.

Title: Improvements in or relating to hydraulic jacking systems for vehicles
IPC: B60S9/12
Filed: 1947-05-13
Abstract: 623,523. Hydraulic machines and intensifiers. ZWICKY, J. F. May 13, 1947, No. 12908. [Class 69 (ii)] [Also in Groups XXX, XXXI and XXXII] An attachment for a hydraulic jacking system for a vehicle comprises one or more hydraulicallyoperated sprags or like holding means adapted to be pivotally mounted on the axle, chassis or other suitable part of the vehicle and which operate at a pressure lower than the lifting pressure of the jacks, and a non-return valve on the inlet side of the sprags. A common hydraulic system may be provided to operate the sprags and the jacks, giving a low pressure supply for the sprags to contact the ground without them effecting any lifting influence, and a high pressure supply for the jacks. The sprags may be mounted singly or in pairs. As shown, the sprags 28 are mounted in pairs on a trunnion plate 33 capable of a self-centring action in the longitudinal plane of the vehicle. The members of a pair of sprags may be so mounted that they diverge from a plane at right angles to their axis of pivotal movement. High and low pressure cylinders 8, 9 are connected in tandem by a connecting rod 11 and operated by a lever 10. Fluid is supplied to the inlet side 14 of the low pressure cylinder 9 by a conduit 13 from a supply tank 12. Low pressure fluid is delivered from the cylinder 9 to the inlet side 18 of the high pressure cylinder 8, to a manifold or distributing device 16, and to a conduit 35, including a non-return valve 40, leading to the cylinder 32 of the sprag 28. The outlet 19 of the high pressure cylinder 8 is connected by a conduit 20 to the manifold 16 which is connected by conduits 17 to the vehicle jacks 4 of known type. On operation of the lever 10 the system is charged with low pressure fluid and the shanks 30 of the sprags 28 and the rams 5 of the jacks 4 engage the ground. Further operation of the lever 12 to lift the vehicle causes a back pressure caused by the ground resistance to the rams 5 to operate on the low pressure inlet side of the manifold 16 through a passage 25 to close a spring-loaded valve 23 and the low pressure fluid then opens a spring-loaded relief valve 22 which short-circuits the supply of the low pressure fluid for the manifold 16 and the jacks 4 back to the tank 12. High pressure fluid then operates the rams 5, lifting the vehicle clear of the ground. To lower the vehicle, a valve 39 is opened to allow both high and low pressure fluid to pass back to the supply tank 12.

In a railway ballast-distributing machine 1 travelling on a track 7, ballast left lying on the track, e.g. after a ballast-cleaning or compacting operation, is picked up and redistributed, preferably in controllable amounts, by a rear unit 14 comprising a conveyer 13 fed by a transverse conveyer 12 and rotary ballastremover 10, the remover 10 having elastic radial members contacting at least the tops of the sleepers 8. The unit 14 shown is vertically adjustable, and incorporates baffles 11 and oppositely-moving transverse conveyers 12 feeding central conveyer 13. The ballast bed is profiled by a vertically-adjustable front scraper 4 and by outer strippers 14'. As shown in Fig. 1 the conveyer 13 lifts the ballast to a vertically-adjustable hopper 15, where it may be cleaned, and from which it is distributed on to the sides of the track through flapcontrolled openings 15". In modifications. Fig. 4, the conveyer 13 discharges through a regulator 16 on to transverse conveyers 17 feeding long or short longitudinal distributing conveyers pivoted at 18' and depositing the ballast either behind or in front of the remover 10. Alternatively ballast may be discharged from the front ends of the conveyers 18 and be distributed by a plough beneath the conveyer 13. In further modifications the conveyer 13 distributes the ballast through a plough, scraper, or chutes. Reference has been directed by the Comptroller to Specification 1,051,247.

Abstract: 646,492. Valve relay circuits ; automatic gain control. TELEPHONE MANUFACTURING CO., Ltd. May 28, 1945, Nos. 13303 and 21238. [Classes 40 (v) and 40 (vi)] In a circuit for detecting impulsive trains of carrier waves, distortion is minimized by applying an automatic bias potential to compensate for changes in input level, and providing means directly operated by the signal, whereby the potential is sustained between impulses. A detector V operating relay R is provided with fixed bias E o  and in addition with automatic bias by means of condenser C whose discharge path includes a bridge network of non-linear resistances W. The output of the valve V comprises rectified signal and also an amplified component of carrier frequency which is applied over transformer T1 to the terminals b, b1 and causes the bridge to present a low resistance across terminals a, a1 ; this enables the condenser C to charge rapidly and develop a bias voltage proportional to the signal amplitude. When the signal ceases, the voltage across terminals b, bl disappears and the bridge presents a high resistance to the discharge of the condenser. The transformer T1 may be tuned to a particular frequency and may alternatively be inserted in the input circuit of the valve V ; the controlling voltage may also be provided by means of an auxiliary valve.

The gases from a bulleted cartridge 12 are led to the supplementary barrel 13 by a passage 15. The rifle barrel 2 is screw-threaded into a sleeve 7 rigidly secured to the fixed cartridge chamber 1 and is longitudinally displaceable by rotation thereof to vary the width of the gap 16 between the end of the barrel and the fixed chamber. By this means, the amount of gas deviated into the barrel 13 can be regulated. The means for rotating the barrel comprises a spurwheel 8 integral therewith which meshes with a toothed sleeve 9 loosely mounted on the barrel 13. A beaded ring 10 integral with the sleeve 9 facilitates the manual rotation thereof. In the rearmost position of the barrel, the gap 16 is eliminated and the weapon may be used as an ordinary firearm.

Abstract: 1517231 Counting by weighing NATIONAL CONTROLS Inc 2 April 1976 13520/76 Addition to 1517220 Heading G1W A group of articles is "counted" by first weighing a sample of a known number of the articles, storing a digital representation of this, weighing the group, and calculating the number of articles in the group. The weighing is done by a load platform (14) connected by a central stalk to a straingauge load cell 13 arranged to be insensitive to lop-sidedness of the load and the electric signals obtained digitized by a dual ramp A-to-D converter 79. A microprocessor performs the storing and calculating, the weight and number of articles in the group being displayed and printed. The weights used for the calculation are averages of 16 consecutive conversions from 79 which must all lie within certain limits of the average to be accepted. A tare facility is provided. If the load is below a certain level, the load platform is assumed to be empty and an automatic zero drift correction routine is initiated in which the zero error is iteratively stepped to zero. If the sample size is too small for accurate calculation, the count indicator shows ADD as a warning. The sample size is selectable, e.g. 8, 16, 32 or 64.
