Title: Improvements in or relating to apparatus for measuring ultra-high frequencies
IPC: G01R23/04
Filed: 1940-04-04
Abstract: 539,954. Frequency measurements. KHARBANDA, S. R. R., and PYE, Ltd. April 4, 1940, No. 6110. [Class 37] Signals from a standard ultra-high frequency oscillator and from an oscillator under test are fed to a mixer in the output circuit of which is connected a heterodyne indicator, and the output from a further variable frequency checking oscillator is also fed to the mixer and used to measure the heterodyne frequency produced by the two ultra-high frequency signals, calibrated means being provided for indicating the adjusted frequency of the checking oscillator. The standard oscillator SO, Fig. 1, is crystal controlled and is followed by frequency multipliers FM, the output of which together with the output from the oscillator TO under test is fed to a mixing circuit M comprising an acorn type triode or diode with either a tuned or an aperiodic input circuit. In the anode circuit of the mixing valve are inserted an amplifier and an indicating device I, which may be a telephone or a cathode-ray oscillograph. Connected through switches to the anode circuit of the mixing valve are a checking oscillator FCO, permanently tuned to 30 kilocycles per second, and a calibrated checking oscillator VCO, the tuning of which is variable from about 10 kilocycles to 8 megacycles per second in a number of steps. In order to measure frequency drift in the oscillator TO, this is adjusted to produce zero-beat with the nearest harmonic from the standard oscillator SO, e.g. the 600 megacycle per second harmonic. Drift of frequency produces a beat frequency in the anode circuit of the mixing valve. If this is greater than 10 kilocycles the oscillator VCO is adjusted until its output coincides with the beat frequency and the drift is read on the dial of the oscillator VCO. If the drift frequency is less than 10 kilocycles the fixed oscillator FCO is switched on together with the variable oscillator VCO. In order to determine which harmonic of the standard oscillator is being employed, a linear tuned element is very loosely coupled to the output of the final multiplier stage of the standard oscillator. The physical dimensions of the line then indicate the order of the frequency with sufficient accuracy to identify the harmonic. A tuned concentric line as shown in Fig. 2 may be employed. A plunger 20 is moved by an insulated handle 21, its position when resonance occurs being read on a scale 23 so as to indicate the order of the harmonic.

Abstract: 526,880. Garment presses. BRAITHWAITE & SON ENGINEERS, Ltd., I., BANKS, W., and O'BRIEN, T. H. Feb. 24, 1939, No. 6120. [Class 138 (ii)] In a swinging head press particularly as described in Specification 504,727 wherein the head is oscillated by a hydraulic cylinder operating through levers with a camming action, the cylinder and the pump supplying the power liquid are arranged in a closed circuit and the supply to the cylinder is controlled by an elecrically operated valve; a dashpot is also provided for controlling the final closing and opening movements of the press; two or more presses may be operated simultaneously or alternately by an electric control circuit having contacts necessitating the use of both hands of the operator until the press is almost closed. As shown the, or each, press has a head carried by arms 3 with cam shaped extensions A which are worked about a pivot 4 by an arm K which is connected by a link N to the arms 3 and by a link k to the piston rod J of a piston H in a cylinder H<SP>1</SP> connected in a closed circuit with an impeller pump B, Fig. 3, driven by a motor C and slide valves G<SP>1</SP>, G<SP>2</SP> which are opened by solenoids S<SP>1</SP>, S<SP>2</SP> in the case of two presses, one valve only being necessary in a single press installation. The arm K carries rollers L constrained to move in vertical guideways M and also rollers P which ride along concentric surfaces a of extensions A during the major part of the closing movement of the press and finally ride up the faces a' to give increased pressure in the closing movement. Two presses operated alternately are controlled by an electric circuit shown in Fig. 7 wherein depression of buttons C' and N<SP>1</SP>, spaced apart to require the use of both hands, closes switches C' and C' to complete a circuit to a soleniod S' which then actuates the valve G' to effect cleaning of the first press, the depresion of the button N' also opening a switch O<SP>2</SP> in the circuit of the second press to allow this to open or prevent its operation. When the first press is almost closed the circuit is maintained through a switch LS' mounted on the extensions A and the buttons C', N' can be released. The second press is operated by depressing buttons C' and M' which close switches C<SP>2</SP> and C<SP>6</SP> in the circuit of the solenoid S<SP>2</SP> actuating the valve G<SP>2</SP> of the second press, the button M' also opening a switch O' in the circuit of the solenoid S' so that the first press can open. As the head approaches fully closed and fully open positions its movement is checked ; on closing, a roller 13 on the arm 3 acts directly on a pivoted lever 6 engaging a dashpot 5a, and on opening, the roller 13 acts through a pivoted lever 7 to rock the lever 6. Reference has been directed by the Comptroller to Specification 504,727.

Abstract: 963,529. Programmed control of machine tools. BENDIX CORPORATION. Feb. 18,1963 [March 1, 1962], No. 6456/63. Heading G3N. In a numerical control system for a machine tool the set feed-rate is modified in dependence on the resolute of the co-ordinate displacements forming an increment of tool movement. As snown, a punched tape 10 passes through a tape reader and temporary storage 10 whereby the digital data,representative of desired increments of movements along coordinate axis DX,DY,DZ and the feed rate FR, is fed to a controller and active storage 14. Signals from the active storage T4 are fed to a decode and hold unit 34 deriving analogue voltage representations VDX, VDX, VDZ, VFR. The feed rate analogue signal VFR is fed through an acceleration deceleration network 36, comprising a by-pass filter, which eliminates any sharp discontinuities in the feed rate to control in direct ratio the pulse rate of a voltage-controlled pulse generator 26. The co-ordinate analogue signals VDX, VDX, VDZ are fed to a reactor magnitude circuit 38 which generates an analogue voltage VR representative of the geometric sum of the co-ordinate distances. The voltage VR is fed to the voltage-controlled pulse generator 26 to vary the pulse rate in an inverse ratio. The output pulse rate of the generator 26 being proportional to the ratio between the desired feed rate and the resultant path length of an increment. The rate controlled pulses are fed to the controller 14 which develops three pulse trains which are transmitted to the X, Y, Z servomechanism 16, 18, 20 to effect an increment of movement of a controlled device 22. In a modification, a pulse multiplier, as disclosed in Specification 848,647 is utilized to allow the controller and pulse generator to operate at a fraction of the rate at which pulses must be provided to the servomechanisms. In a further modification a transducer senses some factor of the cutting conditions of the controlled device, for example by means of a strain-gauge, and controls an adaptive factor summer between the decode and hold unit and the pulse generator to decrease the cut with increase in strain on the controlled device.
