Title: Improvements in conveying mechanism for biscuit making or the like machines
IPC: A21B5/02
Filed: 1923-12-21
Abstract: 232,654. Vicars, T., and Vicars, E. L. Dec. 21, 1923. Sheet-cutting machines.-Cut biscuits &c. are delivered by a conveyer on to pans movable laterally of the direction of travel of the conveyer. The pans are stationary during delivery and the delivery conveyer is furnished with a knife which reciprocates the distance of a pan to deliver a complete panful of biscuits &c. As shown, the biscuits pass from a cutting conveyer 73 on to the delivery conveyer 26 via intermediate and distributing conveyers 60, 44, and are delivered on to pans carried by transverselymoving chains 32. The conveyers 60, 44 are driven continuously and the conveyer 26 is driven through segmental gears 19, 22 and 20, 23 so as to move forward at increased speed after receiving biscuits from the conveyer 44 and then remain stationary while the knife 29 is reciprecated to deliver the biscuits to a pan. The conveyers 60, 44 are also furnished with reciprocating knife edges, the conveyer 60 being arranged to deliver half a cut of biscuits to the conveyer 44. Motion is imparted to the various conveyers through gearing from the shaft 1 and the various knife edges are operated through lever mechanism.

Title: Improvements relating to electronic apparatus for counting electrical impulses
Inventor: CHURCHILL JOHN LESLIE WESTON
IPC: H03K25/00
Filed: 1952-12-18
Abstract: 737,807. Pulse counting circuits. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd. Jan. 11, 1954 [Dec. 18, 1952], No. 32145/52. Class 40 (6). In a pulse counting or frequency-dividing circuit a pulse is injected into a closed circulating loop each time that an input pulse is received and the circulating pulses are counted by an integrating storage circuit which delivers an output pulse each time that the pulses in the loop exceed a predetermined number. Figs. 1 and 2 show a pulse counting circuit in which each input pulse, Fig. 2A, triggers a pulse generator the output pulses from which circulate in a closed loop, Fig. 2B, via the delay memory, a gate and pulse generator circuits. A stepped voltage, Fig. 2C, is built up across capacitor C until when 10 pulses are circulating in the loop, e.g. in period T3-T4, the discriminator is triggered and an output pulse, Fig. 2D, is produced. At the end of each charging period, i.e. at times T2, T3, T4, &c. the discharge generator discharges capacitor C, the circuit being self-running as at each discharge a pulse is injected into the circulating loop which after once being circulated returns through the gate to re-trigger the discharge generator. When an output pulse is produced the gate circuit is closed for a long enough time to block the circulating pulses; the pulse which effects closure being applied via a gate delay circuit. The circuit is thus re-set to commence a further count. To prevent a circulating pulse and a discharge pulse from cancelling each other the pulse generator is temporarily cut off whilst a discharge pulse is generated.

Title: Improvements in or relating to steering gear for fluid borne vehicles
IPC: B63H25/28
Filed: 1939-12-14
Abstract: 555,441. Fluid-pressure servomotor-control systems. PAINE, H. SCOTT-, and THOMAS, D. R. Dec. 14, 1939, No. 32263. [Class 135] (Also in Groups XXXIII and XXIV] Steering-gear for a fluid borne vehicle or boat is provided with a changespeed gear between the actuating member or handwheel and the operated part such as the steering road wheel or rudder. A fluidpressure servomotor is also provided if necessary. In the construction shown the shaft 32, Figs. 2, 4, of the hand-wheel 33 drives a hollow concentric shaft 34 either directly, when a slidable clutch 44 engages clutch teeth 41 on the hollow shaft, or through a gear train 38, 39, 37, 36 when the clutch engages clutch teeth 40 on the gear 38. The clutch is shifted rapidly from one position to the other by means of a screw shaft 47 engaged by a nut 49 slidable but not rotatable within the boss 48 of a fork 46 controlling the clutch. Springs 51 normally keep the nut in a central position in the boss, and a spring detent 55 tends to keep the boss in one or other of the gear positions. When the shaft 47 is rotated to change the gear the nut is moved axially in the boss until one of the springs 51 is compressed sufficiently to overcome the spring detent and move the boss rapidly from one gear position to the other. The detent may be positively released when one of the springs has been compressed an appropriate amount. Three speeds may be provided in the changespeed gear instead of two. The final driven shaft 34 of the change-speed gear carries a sprocket wheel 35 connected by chain drives 12, 14, Fig. 1, and mechanism 15 to a rocking shaft 17 having an arm 18 which slides a valve 19 in a casing 23 having centring springs 24 for the valve. The valve has three ports, the middle port 21 being always open to a supply port 25, and the end ports 20, 22 being connected to the ends of a cylinder 4 the piston of which is connected by a rod 6 to the head 7 of the rudder 8 or other steerable part. The other end of he rudder head 7 is connected by a link 9 to the servomotor casing 23 to give a follow-up motion. If the servomotor fails the rudder is moved by hand-power acting through the valve 19, casing 23, and link 9, the first part of the motion compressing one of the springs 24. An indicator 60 shows the position of the rudder &c., this indicator being driven through a vertical shaft 59 driven by worm gear 57 from the tayshaft of the change-speed gear, this layshaft being always connected through a fixed gear-ratio to the rudder.

Title: Improvements in the manufacture of ethylene oxide
Filed: 1935-11-22
Abstract: In the manufacture of ethylene oxide by the oxidation of ethylene, and the removal of the oxide from the resultant gases by the use of active carbon as an adsorbent, the formation of ethylene glycol in the carbon owing to hydrolysis is minimized by subjecting it each time before use, after desorption by wet steam, hydrocarbon or halogenated hydrocarbon vapour, e.g. benzene or carbon tetrachloride, to drying by means of hot air or inert gas to such a degree that no appreciable amount of desorbed water is detectable in the effluent gas.  The flow of hot air or gas, e.g. at 120--250 DEG  C., is continued until the outflow temperature is substantially the same as the inflow temperature.  The hot carbon is then cooled before the next adsorption phase. Overheating of the carbon containing adsorbed ethylene oxide is prevented by the use of saturated steam for desorption or by the use of an adsorbing column tall in comparison with its diameter. Ethylene oxide is recovered from the product of adsorption by washing with a suitable solvent, or liquefaction, followed by fractionation.  Specification 431,966 is referred to.ALSO:In the manufacture of ethylene oxide by the oxidation of ethylene, and the removal of the oxide from the resultant gases by the use of active carbon as an adsorbent, the formation of ethylene glycol in the carbon owing to hydrolysis is minimized by subjecting it each time before use, after desorption by wet steam, hydrocarbon or halogenated hydrocarbon vapour, e.g. benzene or carbon tetrachloride, to drying by means of hot air or inert gas to such a degree that no appreciable amount of desorbed water is detectable in the effluent gas.

Title: Improvements in steering turntables for road trailer wagons
IPC: B62D7/02
Filed: 1947-12-11
Abstract: 635,646. Turnable forecarriages; vibrationdampers. DYSON, J., POLLARD, T. A., BARKER, S., and DYSON & CO., Ltd., R. A. Dec. 11, 1947, No. 32638. [Classes 108 (ii) and 108 (iii)] In a ball-bearing steering turntable for a road trailer wagon, normal ball-bearing action obtains between the race rings, which are then separated and rotatably free of each other, when the trailer is stationary, but when the trailer is being hauled, the rings make direct frictional contact. In the arrangement shown, upper and lower rings 1 and 6 which are secured by lugs 2 and 2a to cross-members of the trailer and a steering forecarriage respectively, are each formed with opposed ball-race grooves 10 and 11, the sectional curvature of which is greater in radius than that of balls 12 which are disposed between them. The grooves 10 and 11 are formed in an annular channel 13 and ridge 14 respectively, which are complementary in shape and between which there is clearance when the trailer is stationary. A locking ring 17 secured to the upper ring 1 is provided with an annular lip 18 which with ring 1 forms an annular side recess for a shoulder 15 formed by the periphery of the ridge 14. When the trailer is stationary, the rings assume a relatively concentric position, as shown, but when the trailer is being hauled, the rings are relatively displaced to effect a lifting and wedging action between the races 10 and 11 whereby the draught is transmitted by the direct contact of the vertical surfaces of the ridge 14 and the channel 13 and by the abutment of the lip 18 against the shoulder 15. The lugs 2 and 2a may each be replaced by an annular flange rolled integral with or welded to the rings 1 and 6. Also, only one of the grooves 10 or 11 may be greater in radius than that of the balls 12.

Filed: 1966-07-21
Abstract: 1,158,329. Backscatter gauge. INDUSTRIAL NUCLEONICS CORP. July 21, 1966 [July 22, 1965], No.32798/66. Heading G1A. In a backscatter gauge for determining the thickness, weight per unit area density of, or presence of a particular substance in, a layer 4 forming a cover on a layer 5 of a material having a different characteristic, the radiation source is arranged to produce collimated radiation at a very acute (almost grazing) angle to the surface of the cover layer 4 and a detector arrangement 47 views the backscattered radiation. One detector 32, having a collimator casing 34, is located to receive primarily radiation backscattered from cover layer 4 (from volume 16) and minimal backscattered radiation from backing layer 5. The other detector receives radiation backscattered from the backing layer 5 (volume 17). The sensitivity of the apparatus can thus be made independent of the nature or thickness of the backing layer 5, which in some cases may be liquid or gas. The source may be of y-radiation e.g. Cs 127 or alternatively a # or bremsstrahlung source, and the detectors ionization gauges or scintillation counters. The source and detector mountings are adjustable to obtain maximum response, but are fixed relative to one another and to the position of the surface of layer 4 during measurements. A scanning of the surface is obtained by movement of the sheet 15 or of the gauge itself. The detector outputs are submitted to a computer (37), which sums or takes the ratio of the signals, producing an indication on a meter (39) of the property of interest. Separate sources may be used for the detectors.
