Title: Improvements in and relating to coin-testing devices
IPC: G07D5/04
Filed: 1931-10-13
Abstract: 385,689. Coin-freed apparatus. FISHBURN, J. E., 39, St. James' Street, London, and WEBB, C. F., 33, Kenton Park Avenue, Kenton Park, Middlesex. Oct. 13, 1931, No. 28465. [Class 27.] Testing coins.-A coin-testing device, particularly for coin-freed machines, comprises a balance 1, 2, Fig. 1, pivoted at 3 and provided with an adjustable counterweight 5, the arm 1 having a platform 8 which receives coins from a shoot 14. If the coin is of proper weight the arm 1 moves down until the platform 8 is in alignment with a shoot 16 into which a correct coin passes. If the surface of the coin is smooth and there is no rim, thereby providing insufficient friction, sufficient potential energy will be developed in the coin to cause it, as it moves with the balance, to slide off into a return shoot 15 located above the shoot 16. The platform 8 is attached to the arm 1 by a screw 9, Fig. 3, its inclination being adjusted by screws 11 and knife-edges 12. Pins 13 position a coin correctly on the platform so that a ring of steel balls 10 fit just inside the rim of the coin and engage frictionally with the surface of the coin. When the platform 8 is aligned with the shoot 16, a pair of extensions 17 of the shoot pass through slots in the platform and raise the coin so that it can slide off. In a modification, Fig. 6, a ring of hardened steel points 10a are provided which engage within the ring of lettering 18a on the coin.

Title: Adaptive delay line equaliser
IPC: H03H15/00
Filed: 1969-06-06
Abstract: 1,256,405. Adaptive transversal equalizer. INTERNATIONAL BUSINESS MACHINES CORP. 6 June, 1969 [13 Sept., 1968], No. 28639/69. Heading H4R. In an adaptive equalizer, particularly for use in a system in which data signals are transmitted with correlation between successive digits, e.g. where a "1" is transmitted over three digit periods as +A, O, - A and a "O" is transmitted as -A, O, +A, the multipliers of the equalizer are adjusted during transmission by signals derived from the output of the equalizer, as quantized output signals and as errors of the output signal from the quantizing level, which are multiplied together and time spaced multiples are combined to provide incrementing signals for the equalizer multipliers. As shown, Fig. 1, the equalizer comprises tapped delay line 103 with the outputs at the various tappings combined via attenuators 108 to 132 in summing amplifier 143 to provide the equalizer output. A threshold detector 144 connected to the output provides one output representing the sign of the output, i.e. if the output is +A or -A, a second output representing the sign of the error from the most likely value, and a third output if the most likely value is zero. The sign of error signal is fed to shift registers 146 and 147 to provide signals spaced in time by 10 digits, for signal sgn e k   +   2  and by 12 digits for sgn ek, which signals are fed to the multipliers 208 to 232 in the adapting circuit of the equalizer together with the sign of the output signal a k   +   12 , after it has been fed through the appropriate stages of the shift register 145. The  multipliers are also supplied with pulses from a clock 205 and include 2 stage shift registers to allow multiplication together of differently timed multiples of the input signal. The multiplier outputs from spaced stages are combined to provide inputs for the storage counters 238 to 262 which perform an integration function and control the up-down counters 268 to 292 to adjust the attenuators on the delay line taps. The adapting circuit provides a solution to the equation where e is the error in the equalizer output from the desired value, a is the desired equalizer output value and h j  = the system impulse response for j # 0 and h j  = h 0  - 1 for j = 0.

Abstract: 683,479. Travelling-wave tubes. SYLVANIA ELECTRIC PRODUCTS, Inc. Nov. 11, 1949 [Nov. 13. 1948], 28983/49. Class 39(i) [Also in Group XL(b)] In a travelling wave amplifier with an input probe, output probe and a helix therebetween metal discs sealed through the envelope are used to provide electrical connection to the probes and mechanical support for the helix. In a modification there may be two or more helices. In one form, Fig. 1, the helix 20 is connected to discs 28, 34 via probes 16, 18 and short circuited matching coaxial stubs 38, 44 and is held accurately straight and axial by three hard glass rods 22 having low loss which fit into notches in the discs 30, 32. The stub outer conductors 40 fit slidingly into cylindrical flanges of the discs 28, 34 and are formed with shoulders 42<SP>1</SP> to limit their tendency to sliding displacement caused by the tensioned helix 20. Discs 28, 34 limit any longitudinal displacement of rods 22. Outside the envelope the copper discs are spun over reinforcing rings 36 and attached to input and cutput rectangular waveguides 24, 26. A further disc (not shown) sealed through the envelope may be provided for mechanical support of the helix at a point between the input and output guides, but since no external contact is required the spun over portion and ring 36 may be omitted. In forming the disc seals the discs are held in axial alignment by jigs and the sealing procedure is carried out as described in Specification 630,136. The probes and inner conductors of the stubs may alternatively be separate members connected electrically and mechanically to one another. The envelope 10 is of soft glass and a magnetic coil between the input and output probes focuses the beam. Lumped attenuators are provided at one or more points along the helix to suppress reflections. In a modification, Figs. 3, 4 (not shown) the helix is supported by four low loss ceramic rods which in turn are held at their centre portions by a metal shield surrounding the helix and at their ends by the inner and outer stub conductors. The shield is carried at either end by discs corresponding to 30, 32, Fig. 1. Axial displacement of the rods is prevented by eyelets at the shorted ends of the stubs. Prior art arrangements in which the helix is supported by ceramic or quartz rods or glass dimples in the envelope are referred to. The Specification as open to inspection under Sect. 91, states that the stubs have a length of #/4 as compared with prior art open ended <SP>#</SP>/ 2  stubs. In the form of Figs. 3 and 4, (not shown) the internal tube parts may be constructed to allow for differential thermal expansion. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to condensing gases by direct contact with immiscible cooling liquids
IPC: B01D5/00
Filed: 1951-12-14
Abstract: <PICT:0704580/III/1> In order to effect substantially total condensation of vapours which contain both readily condensable fractions and less readily condensable fractions, the vapours are introduced into the base of a direct contact condenser which is supplied at the top with a cooling liquid that is immiscible with the vapours; both the cooling liquid and the condensate of the readily condensable fractions of the vapours are withdrawn from the base of the condenser, the condensate of the readily condensable fractions is introduced into the top of the condenser wherein it acts as a condensing and absorbing liquid for the less readily condensable fraction, and the total condensate required as product is accumulated in, and withdrawn from, an intermediate section of the condenser. Water may be used as cooling liquid for the condensation of the vapours, containing gasoline together with C4 and lighter hydrocarbons, obtained as overhead in the fractionation of the products of the catalytic cracking of gas oil.  The vapours are introduced through inlet 4 into the bottom of tower 1, which is filled with disc and donut packing.  Water is supplied to the tower through inlet 5.  A mixture of water and the condensed heavier components (C5 and above) of the hydrocarbon-feed is withdrawn from the tower through line 6, and is allowed to separate into two layers in drum 7.  Water is withdrawn through line 8.  The condensed naphtha is withdrawn from drum 7 through line 9, and is pumped into the top of the tower. The liquid which accumulates in annular ring 2 comprises a mixture of water and the naphtha together with C4 and C3 hydrocarbons.  The mixture is withdrawn through line 3 into drum 10, where it separates into two layers.  The water withdrawn from the lower portion of drum 10 through line 12 is returned to the tower below ring 2.  The upper liquid layer in drum 10 is the required condensate, and this is withdrawn through line 11.  In some cases it is desirable to introduce a portion of this condensate into the lower section of the tower through line 32.  The gases withdrawn from the top of the tower through line 13 comprise C2 hydrocarbons, methane and hydrogen.  In another embodiment, the condensed heavier fraction, withdrawn from the base of the condenser, is cooled, by counter-current direct contact with another flow of water, before it is introduced into the top of the condenser.

Abstract: 627,406. Moulding artificial teeth. LEADER, S. A. Oct. 2, 1946, No. 29414. [Class 87 (ii)] [Also in Groups VI and XVIII] Several thermoplastic or thermosetting synthetic resin powders each of different colour, and each contained in a separate tube 17 are successively fed, under gravity, through a hopper 10, a chamber 4, and canal 6 into mould cavities 7, in a two-part mould 2, 3 described in Specification 627,464, whilst vibrating the mould. After filling, the mould is heatedto moulding temperature, and pressure is applied by a plunger acting on the material in the chamber 4. A blending effect between adjacent layers of colour is obtained by means of the vibration. The moulds may travel on a conveyer through a heating tunnel to heat the moulds prior to filling or to heat the moulds for the moulding operation. A lubricant such as cetyl alcohol, stearic acid or silicone grease may be used to facilitate removal of the moulded teeth. The hopper or the mould may be rotated. The two parts of the mould are held together by cam clamps 8. In a modification (Figs. 4 and 5 not shown), the mould is provided with several separate filling chambers, canals and mould cavities, the mould being split in two parts about a vertical plane through the cavities. Pressure is applied to the material by a ram having several plungers corresponding to the chambers or by passing the mould step by step beneath a plunger while the mould is held together between rollers. The resins used may be polymethyl methacrylate, polystyrene, polymerised allyl methacrylate, or phenol-formaldehyde. The feeding device consists of a tube 17 having a false bottom 20, with an opening 21, and a hemispherical bottom 18, with an opening 19. The tube normally rests against an adjustment screw 22, in which position material flows through the opening 21 into the bottom 18, until the level of the opening 21 is reached. Then, when the material is required, the tube is tilted to allow the material to flow out through the opening 19.
