IPC: H01J47/08
Filed: 1952-05-08
Abstract: 746,172. Geiger counters. TEXACO DEVELOPMENT CORPORATION. May 8,1952, No. 11640/52. Addition to 612,899. Class 39 (1). In a radiation detector as described in the parent Specification, comprising a plurality of substantially parallel cathode plates 11 of substantially equal area, spaced apart from one another, each plate being formed with one or more apertures 12, said apertures being disposed in alignment, and an anode wire 13 extending through each series of aligned apertures and insulated from said plates, the number n of apertures in each plate is made approximately equal to the value 4A/#S<SP>2</SP>K<SP>2</SP> where A is the area of one of said plates measured in square inches, S is the spacing between adjacent plates and is between 1/8 and 3/16 inch, and K is a factor having a value in the range of from 4 to 8. The diameter of each aperture is preferably at least twice the value of S. The formula gives the optimum relationship between the number of apertures and hence of anode wires and the plate area to obtain a reasonably uniform field distribution as well as a satisfactory plate area, and shows that the number of apertures n is also approximately equal to the area A of each plate measured in square inches.

Abstract: 1423510 Arc limiting DELTA CONTROLS Ltd 1 March 1973 [13 March 1972] 11695/72 Heading H1N [Also in Division H2] An overload protective device comprises current sensing means 10, 14 providing a signal when the load current exceeds a predetermined value, semi-conductor current limiting means 8 to limit the load current in response to the signal and an electromagnetic relay arrangement to break the circuit in response to the signal. As shown, when the current through a resistor 10 exceeds the predetermined value, an amplifier 14 provides the signal to the bases of transistors 18, 23. These transistors now conduct, the transistor 18 causing the current limiting transistor 8 to limit the current and the transistor 23 energising the coil 6 of a relay which opens contacts 4 in the load circuit and opens contacts 26 to hold the transistor 23 on by a bias due to resistors 28, 30, so that the relay coil remains energised.

Abstract: 500,326. Coin-freed article-delivery apparatus. HORNBRUCH, O. April 22, 1938, No. 12149. Convention date, Feb. 22. [Class 27] Coin action, weight.-The bottom article of a pile in a magazine 21 rests in a tray 10, Fig. 1, hinged at 23 and held up by a hook 8 engaging a pin 28 on the tray. A coin inserted through a shoot 12 drops on a bucket 35 on one end of a coin-lever 11 tilting this against the action of a spring 33 and freeing its other end from a pin 22 on a depending lever 6. The lever 6 is pivoted at 24 and, when released, is pulled by a spring 15 to engage a screwed stop 27 on the hook R which is rocked to release the tray 10. The tray swings down as shown in Fig. 5, to allow the bottom article to slide off to a delivery shoot. The next. article is supported by a curved abutment on the inner edge of the tray and by a gripper 16 adjustably mounted on a depending arm carried by a rockable spindle 17, which has another arm 4 constantly pulled towards the articles in the pile by a spring 13. The lever 6, when released, by a pin 7 actuates also the arm 18 of a mercury switch to start an electric motor which drives a shaft 1 carrying a cam 2. The cam raises the tray 10, and a lever 9 pivoted at 29 to the tray engages an inclined abutment 25 on the lever 6 to return this lever to its initial position, where it is again held by the coin-lever 11. A pin 3 on the cam engages the arm 4 to press back momentarily the gripper 16 and release the next article, the gripper then springing back again and pushing this article which is now the bottom one into the tray as shown in Fig. 4, and supporting the next one.

A machine for armouring electric cables has endless belt means, for pushing the cable, at the entry end of the machine and endless belt means, for pulling the cable, at the exit end, the two endless belt means being actuated by common driving means. The rear end of lead-sheathed cable 1 and the forward end of similar cable 1A from a reel 8 are cleanly cut by circular saws 12 and are brought together and are secured temporarily end-to-end by a strip of adhesive tape. The cable is fed forward by endless belts 9 driven through a clutch 11 from a main shaft 35 and is withdrawn from the machine after armouring by endless belts 30, driven from the shaft 35, to be wound on a reel 33. When the temporary connection passes the belts 30, the pushing belts 9 may be declutched and the connection removed by a saw 32. The cable passes through sprinkling-tanks 13, 17, 20, 24 and 27, to coat the cable, e.g. with pitch, and heads 16, 19, 22 and 26 rotated by the shaft 35, to wind on to the cable, in succession, paper tapes 3A, 3B, cord 4A, 4B, steel strip 5A, 5B, from large reels 23A, 23B of strip welded endto-end, and cord 6A, 6B.

Title: Improvements in or relating to electric motor control systems
IPC: B60L7/04
Filed: 1946-04-24
Abstract: 611,172. Control of D.C. motors. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. April 24, 1946, No. 12350. Convention date, Sept. 19, 1944. [Class 38 (iii)] Dynamic braking is automatically applied to an electrically-propelled vehicle on failure of the supply by a normally closed switch which is opened by the application of supply voltage before actuation of one motor controller from its " off " position. Supply of current to the motors is dependent upon the opening of this switch and after emergency braking current cannot be restored to the motors until the controller has been returned to its " off " position. The operation of one overload relay does not cause dynamic braking. The invention is described as applied to an electric trolley vehicle. In the Figure, when switch CS is closed, the supply voltage energizes a magnet coil to open the normally-closed contacts S in the dynamic braking circuit and to close contacts S1. Movement of controller C will now energize-through contacts S1-a coil to close contacts M and auxiliary contacts M1; the former connect motors 10 and 11 to the supply, the latter parallel contacts closed only on the first step of the controller. Failure of the supply causes contacts S1-and hence contacts M-to open; contacts S close to connect the motors 10 and 11 in two closed circuits through braking resistance BR, each motor energizing the series field of the other. Contacts M cannot be reclosed until, on restoration of the supply, contacts S1 reclose and, because contacts M1 are open, until the controller is returned to its first position. The overload magnet causes contacts M to open, without affecting contacts S, and also closes the circuit of a coil for maintaining itself until the controller is brought to the " off " position.

A dough moulding machine comprises two rollers 3, 4 ; a converging, band 5 to receive pieces of dough flattened between the rollers and shaping means which comprises two plates 7, side by side, secured at their discharge ends to a rod 8 which is supported in eccentric bearings, each plate being biased by a spring 10 towards the band 5, and a broad plate which may be detachably fixed to the plates 7, disposed between them and the band, the latter being of a width corresponding to the combined widths of the plates. The plates 7 are thus coupled together when the machine is to be used for moulding twisted loaves. requiring the full width of the conveying, band. For pointed rolls, requiring only half the width, the plates 7 are not coupled and a partition 13 is located at the inlet to the machine and two dough pieces are fed both sides of it simultaneously. When the plates 7 are uncoupled two cloths 11 hang from a rod 12 between the plates and the conveyer band 5. When the said broad plate is secured to the plates to couple them together it is placed between the cloths and the conveyer band and a cloth is hung from the rod 12 against the broad plate. The plates 7 may be slightly curved in transverse section.

Title: Process for the preparation of silage
IPC: A23K30/15
Filed: 1977-03-25
Abstract: Silage is prepared using calcium formate as silaging auxiliary, the starting concentration of calcium formate being 1-5% by weight. In the aforementioned starting concentration, calcium formate is extremely effective as silaging auxiliary and the formation of butyric acid is completely suppressed; however the lactic acid fermentation is not impaired but promoted. The silage prepared with the aid of calcium formate is, despite the high starting concentration, physiologically harmless. The calcium formate is primarily used as such, but can also be mixed with other substances which either themselves have an effect as a silaging auxiliary or are inert.
