Inventor: WHITTAKER WILLIAM
IPC: D07B9/00
Filed: 1969-07-17
Abstract: 1,269,134. Cable couplings. CCL SYSTEMS Ltd. 15 Oct., 1970 [17 July, 1969], No. 36067/ 69. Heading D1T. [Also in Division F2] In a clamping and anchoring device for high tensile rods and stranded cables, a'ductile metal body is provided with apertures, having hardened, serrated surfaces, to receive the rods or cables. The metal body is surface surface carburised, cooled and then machined so as to retain the carbon layer only at the serrated aperture surfaces. After heating the body is oil-quenched to raise the hardness of the serrated surfaces and to render the remaining surfaces ductile, to facilitate the cold pressing or swaging of the soft metal on to the rods or cables. In one embodiment, the element 3 is compressed to secure the rods and cables in the bores, 4, serrated at 5. The annulus, 6, when compressed, grips the element, 3, by the serrated surface, 9, and the rods in apertures 7, by the serrated surfaces 8.

Abstract: 510,428. Coin-freed apparatus. HARPER, P. S. Dec. 16, 1938, No. 36710. [Class 27] [Also in Group XVII] Coin-slit closing-devices; testing coins.-A coin-insertion device for preventing fraud in coin-freed machines and other coin receptacles comprises a pocket 1, Figs. 1 and 8, carried by an escutcheon plate 3 and provided with a slot 4 in its end wall through which the coin passes to the machine or receptacle. Guide slots 5 are provided in the top and bottom walls. A shutter 7 having inturned flanges 8 working in slots 9 in the pocket normally closes the slot 4. A coin inserted into engagement with the guideways 5 makes contact with inclined ramps 15 on the flanges 8 and pushes the shutter aside to uncover the slot 4 so that the coin can pass through. Small coins do not engage the ramps and cannot be inserted. In a modification, Fig. 7, the shutter has an extension 20 with a slot 21 which coincides with the slot 4 only if the coin is of proper diameter.

Abstract: 1350815 Program transfer system: card reader BURROUGHS CORP 9 Aug 1971 [21 Aug 1970] 37258/71 Headings G4A and G4M Programs on a card in the form of dark marks on a transparent base (Fig. 2, not shown) are transferred to a computer memory under the control of a keyboard. Each program is held in a sector of the card having four columns each holding nine bits and having a track holding clock pulses. The card is held on a rotary drum (Fig. 4) and the clock pulses are fed to a scale of 4 counter (Fig. 5, not shown) which feeds a 5 stage counter (Fig. 7, not shown). Keys on a keyboard 21 are pressed to select a program and produce a coded signal identifying the sector of the card holding the program. When the coded signal and the value of the 5 stage counter agree a comparator enables readout of the program into matrix bi-stable memory (Fig. 9, not shown) under the control of signals from the scale of 4 counter ensuring that each card column is fed to a different column in the matrix memory. Card reader.-The card is located and held in a cylinder by lugs and a strap engaging locating holes in the card. The cylinder is located on a shaft 46 and is rotated. Light from source 35 is detected by photo-cells 36 and fed to a gate feeding the computer memory. If the computer is processing a program a BUSY signal prevents addresses of new programs from the keyboard from being stored in register 22 (Fig. 3, not shown).

Abstract: 931,233. Acoustical thermometers. GENERAL DYNAMICS CORPORATION. Oct. 28, 1961 [Oct. 28, 1960; April 27, 1961], No. 38431/61. Class 40 (7). The temperature of a gas-filled acoustical cavity is evaluated from a measurement of the resonant frequency of such cavity. Fig. 1 shows one embodiment in which the cavity 11, positioned within a space 22 (which may be a furnace or atomic reactor) the temperature of which is to be measured, is connected to electro-acoustic transducers 18, 21 via respective coupling tubes 13, 15, the transducer 18 being coupled to a variable (audio) frequency oscillator 25 the frequency of which (in operation) is varied until the signal transmitted through the coupling tubes and the cavity and picked-up by transducer 21 produces (after amplification in 28) a maximum reading on an indicator 29 which may be an oscilloscope. The frequency f, as read on a frequency counter 26, at which this maximum occurs is then employed to evaluate the temperature T from the relationship T = K#<SP>2</SP> where K is a constant. The cavity and the coupling tubes are filled with an inert gas such as argon and the coupling tubes, which are sufficiently long to permit the transducers to be located remotely from the high temperature of space 22, are formed with periodic variations in their outer diameter to prevent a resonant condition in the wall material of the tubes from being established. Fig. 2 shows an alternative arrangement employing a single coupling tube 34 and transducer 36 which is fed from a variable frequency oscillator 42 in a relay 37, the latter being operated via a pulser 41 such that intermittent " bursts " each of about 10 cycles of the output of oscillator 42 are supplied to the transducer (and simultaneously to an oscilloscope 39) which, during intervening periods when relay 37 is open, supplies signals reflected by the cavity 31 to the oscilloscope. In the resonant condition the oscilloscope trace produced by the reflected signals decays to a minimum value (as acoustic power is absorbed by the cavity) and the frequency at which this occurs, as read on a frequency counter 43, is then utilized to evaluate the temperature of the furnace &c. 32 in which the cavity is positioned. In this embodiment the cavity (and coupling tube) is preferably filled with an inert gas such as helium. The invention may also be employed for low temperature measurement and a range of 20‹ to 2000‹ K is specified.
