Title: Improved process of and apparatus for forming ovals
IPC: B24B9/10
Filed: 1930-02-08
Abstract: 336,919. Laffineur, E., and Collin, L. Feb. 16, 1929, [Convention date]. Moulding-machines.-In a device for forming ovals such as an ellipsograph, or a machine for tracing, cutting, moulding, or plastering oval frames or for bevel grinding the edges of oval glass plates, the work axis d is rotated about a fixed point x in a circle having a radius e d equal to a quarter of the difference between the major and minor axes of the desired ellipse a, the work at the same time being rotated on its axis in the reverse direction z at half the speed of the first mentioned movement x. In this way every point on the ellipse a passes through a point b where a tool may be located. In one form of apparatus, Figs. 7 and 9 for bevelling glass plates a sleeve 4 driven from a shaft 5 is connected by a coupling 10 to an upper sleeve 8 having a flange 11, and pins 13, 24 on a plate 14 pass respectively through a hole 13<1> and slot 12 in the flange. The plate 14 carries the work holder 16 on which the glass is secured either by clamps or by suction applied to the passage 18. An internal gear 15 rotatably mounted on the plate 14 drives a pinion 22 engaging a pinion 21 mounted on the pin 13 and engaging a central fixed wheel 3. The gearing is such that the plate 14 is driven at twice the speed of the ring 15 and in the reverse direction. The plate 14 is adjusted by means of the slot 12 so that its centre and thus also the work centre d is eccentric to the fixed point e at the centre of the wheel 3, the eccentricity being equal to a quarter of the difference between the major and minor axes of the desired ellipse. In order to maintain the peripheral speed of the work past the grinding-wheel approximately constant the shaft 5 is driven at a variable speed by means of the gearing shown in Fig. 10. The driving shaft 29 carries a pinion 28 engaging a wheel 26 carried by an adjustable link 30. The shaft 5 is driven by a pin 27 engaging in a slotted crank 25 and by varying the eccentricity of the wheel 26 with respect to the shaft 5 the speed of this latter shaft is varied in the required manner. This mechanism may be employed to drive a number of machines arranged in series, the driving wheel 7, Fig. 7, being connected to a second shaft such as 5 mounted in a bearing 34.

Title: Improvements in or relating to high frequency direction finding systems
Inventor: BAIN WILLIAM CRANNA
IPC: G01S1/02
Filed: 1956-02-15
Abstract: 853,662. Aerials; radio direction-finders. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 15, 1957 [Feb. 15, 1956], No. 4769/56. Class 40(7). A radio direction-finder comprises fifteen or more static aerials arranged in a circle of 5 to 10 wavelengths diameter and phase modulation of the received signals in a frequency changer energized from a phase-modulated oscillator such that all received signals are brought to a common phase at one point on a circular time base to indicate bearing. If there are n aerials in the ring and the amplitude and phase of the k th. aerial output are E k , # k  the apparatus carries out the summation where # k  is a phase delay made to vary as R cos (# o  t - 2k #/n), R being an adjustable parameter and # o  the angular frequency of phase modulation of the delay. It is demonstrated that # o  t corresponds to azimuth, and the maximum value of voltage V 2  as displayed on a circular time base of angular frequency # o  gives the bearing of the received signal. A signal of frequency # o /2# (25 c/s.) from oscillator AO and a quadrature signal from phase shifter PSI are multiplied by factor R in attenuator AT whose outputs are fed to the modulating units of each aerial. The 25 c/s. cosine and sine components are multiplied by cos (2 k#/n) and sin (2k#/n respectively in units Nc, Ns and their outputs are added in unit AD1 the output of which (R cos{# o  t-2k #/n}) is fed to balanced modulator BAM the other input to which is a signal f 1  from oscillator O. A phase quadrature signal of frequency f 1  is added to the balanced modulator output in unit AD2 whose output is frequency multiplied to give a phase modulated signal input to frequency changer FC2. The k th. aerial output after frequency changing in unit FC1 fed also from local oscillator RO is taken to the other input to frequency changer FC2 the output of which is added to similar outputs derived from the other aerials of the ring in unit AD3. After linear detection an output voltage, which is V 2 , is taken to time base circuits CTB1, CTB2 to afford the bearing display on cathoderay tube (CRT) CRTC. A linear time base occupying a fraction of the circle of azimuth is provided for CRTF for more accurate measurement. Alternatively the CRT's may be fed from a phase sensitive detector PSD whose inputs are from amplifier 1A1 and adjustable phase shifter PS3; the phase shifter input comprises the signal from a centre aerial CA after successive frequency changing by inputs from oscillator RO and the frequency multiplied output of phase shifter PS2. To cover a wide frequency range three concentric rings of aerials are provided. Each aerial is a short vertical unipole. In order to align the system, a test signal is transmitted from the central aerial CA and each of the channels from the aerials in the ring are adjusted on this signal to give voltages of the same phase and amplitude at AD3.

Filed: 1944-03-15
Abstract: 592,346. Radar. STANDARD TELEPHONES & CABLES, Ltd. March 15, 1944, No. 4872. Convention date, Jan. 4, 1943. [Class 40 (v)] The receiver in a radar or other radio pulse system is blocked, during the sending of a pulse, by means of low-potential bias derived from current in an inductance or other energystoring element by which the emission is initiated, and the blocking bias begins before and lasts throughout the sending of the pulse, its intensity and duration being adjustable. The sending oscillator comprises valves 42, 44 which oscillate when a,pulse of anode voltage is applied to them through the inductance 26: The pulse-generator comprises a valve 22 whose grid circuit is coupled at 28 to the inductance 26. The receiver (not shown) functions while a charge, which biasses the grid 24 below cutoff is leaking from condenser 29 through resistance 31, and no current flows in the inductance 26. At the end of this period the valve 22 opens and current builds up through the inductance 26 and the anode 23, and so long as current is flowing, a blocking bias, whose magnitude and duration can be adjusted by means of the potentiometer 30 and timeconstant circuit 36, 38 respectively, is applied to the receiver through the lead 40. Meanwhile, the grid is made positive through the coupling 26, 28 and grid current flows. When the saturation current of the valve is reached and the rate of change of the current in inductance 26 is reversed, the grid 24 becomes negative, the valve cuts off, the charge left, by grid current on the condenser 29 produces a large negative grid bias and a sharp peak of positive anode voltage is applied to the oscillator 42, 44, so as to generate a pulse which reaches a maximum voltage and minimum width if the impedance elements in the pulse-generator 14 conform to a critical relation given in the Specification.

Title: Process for the production of metal aluminium hydrides
IPC: C01B6/00
Filed: 1961-02-09
Abstract: A metal aluminium hydride is produced by grinding Al in an inert medium to form an active surface thereon and reacting the Al with a hydride of Na, Li or K with H2 under pressure in a solvent in which the hydride will be formed with the production of heat.  The Na, Li or K hydride may be ground with the Al in the inert medium, e.g. diethyl ether, a polyglycol diether or tetrahydrofuran, and subjected to a hydrogen pressure of 30-200 kg./cm.2 at 30-200 DEG  C. Finely-ground metal may be used in place of the metal hydride and the starting material may contain a salt, e.g. halide, of Na, Li or K. The hydride produced may be separated from the solvent and ground with the above salt in a solvent which is a non-solvent for the metal aluminium hydride but a solvent for the aluminium hydride of the other metal.  The Al may be cast or alloyed with Si and Pb free.
