Abstract: 819,335. Radio receiving circuits. STANDARD TELEPHONES & CABLES Ltd. Sept. 20, 1957 [Oct. 27, 1956], No. 29633/57. Classes 40 (5) and 40 (6). A superheterodyne receiver comprises a pentode H.F. amplifier R÷4 followed by a triode self-oscillating frequency-changer R÷5 to which I.F. regeneration is applied. The anode load of the H.F. amplifier comprises a resistance Ra in series with coil Lr which is back-coupled to tuned anode circuit Lo, C5 to generate the local oscillations. A condenser Ca is shunted across resistance Ra to enable oscillations to be generated at the higher frequencies. The circuit also includes resistance R2 which, in conjunction with condenser C6 and resistance R3 in the anode circuit of the valve gives I.F. regeneration. In a multi-band F.M./A.M. receiver (Fig. 6, not shown) the arrangement is used in S.W./ M.W./L.W. bands: the S.W. aerial coupling coil is permanently in circuit, releasing a switch contact which is used for short-circuiting part of the grid leak of the frequency-changer on this band. On the F.M. band the H.T. is removed from the frequency-changer and the pentode H.F. amplifier is switched to operate as an additional I.F. amplifier, a separate frequency-changer being used on this band. The Specification also describes a known arrangement (Fig. 1, not shown) comprising a pentode mixer with cathode injection of local oscillations from a separate triode oscillator, in which the pentode is combined with a diode which generates a grid bias for the valve from the local oscillations. There is also described another known arrangement (Fig. 2, not shown) comprising a triode mixer with cathode injection of local oscillations from a separate triode oscillator, in which the coupling coil by which local oscillations are injected into the cathode circuit is in series with a further coil coupled to the first I.F. circuit for I.F. regeneration.

Title: Improvements in or relating to steam engines
IPC: F01B17/04
Filed: 1932-10-25
Abstract: 402,585. Steam engines. SOHOLT, J. A., Box 3006, Bygdo Alle, Oslo, Norway. Oct. 25, 1932, No. 29881. Convention date, Oct. 28, 1931. [Classes 122 (ii) and 122 (iii).] A triple-expansion engine is provided with two high, 1, 4, two intermediate, 2, 5, and two low-pressure cylinders 3, 6, arranged as shown in Fig. 1, and connected to cranks inclined at 60‹. During forward running the steam from the H.P. cylinder passes directly to the M.P. cylinder, and from the M.P. cylinder to the L.P. cylinder. During reverse running, some of the steam passes from the H.P. first into an intermediate chest constituting part of the valve chest, and subsequently to the M.P. cylinder. During forward running, the ends of the H.P. cylinder exhaust to the opposite ends of the M.P. cylinders. The H.P. exhausts when the crank has moved 120‹. As the H.P. crank moves from 240‹ to 300‹ the steam flows directly from the H.P. cylinder through the M.P. cylinder to the L.P. cylinder. The exhausts from the H.P. and M.P. cylinders continue during 180‹. In reverse running, the discharge of steam from the H.P. does not open until the crank has moved 180‹. The steam first passes to the receiver, and then directly to the M.P. cylinder. Each cylinder has separate, cylindrical oscillating valves for forward and reverse. The valves 7, 8, 9, 10 are oscillated by adjustable linkage mechanism operated by an eccentric 41. They are moved longitudinally by screw-and-quadrant mechanism 50, 52 for reversal.

Title: Improvements in dual fuel engines
Inventor: BENZ WALTER
IPC: F02D19/10
Filed: 1960-08-30
Abstract: 940,892. Regulating. MOTEREN WERKE MANNHEIM A.G. Aug. 30, 1960, No. 29927/60. Heading F1B. In a dual fuel engine a centrifugal or other governor 19 controls the gas valve 12 and injection pump control rod 16 through a floating lever 22 which is also connected at 25 to a piston 27 controlled by the gas pressure in chamber 29 and air intake manifold pressure in chamber 30. During normal running on gas with pilot fuel injection, the gas pressure in chamber 29 moves piston 27 to the left and the governor 19 moves the gas valve 12 through rods 38, 40, over the normal gas supply range 0-100 on scale 40b. During this operation, the fuel pump rack 15 is held against the pilot fuel stop 18 and its governor operated rod 24 moves freely within the lost-motion space 33. If the gas supply fails or is insufficient for the load on the engine, the intake manifold pressure forces piston 27 to the right, whereby lever 22 moves rods 38 and 24 beyond the fully opened position of valve 12 so that rod 24 contacts rack 16 and increases the liquid fuel delivery to supplement or replace the gas supply. The gas pipe 36 has a constant pressure valve 43 therein which normally maintains the gas at a pressure slightly above the maximum air intake manifold pressure. A shut-off cock 50 in the gas supply pipe 48 is connected to the engine control lever 51 which regulates the speed setting of the governor. The cock 50 is closed in the shut-off position S of lever 51 and open in the normal running range A to B. Lever 51 is connected to pivot 21 of lever 22 and through a spring 56 to the governor setting lever 55. The air and gas supplies to the cylinder are controlled by coaxial mixing valves 3, 5, operated by rocker mechanism 9, the valve 5 being actuated by an abutment 7 on the stem of valve 3.

Abstract: 1433495 Automatic control CINCINNATI MILACRON Inc 21 June 1974 [25 June 1973]  30094/73 Heading G3N In a numerical control system having, in respect of each controlled axis, a source e.g. 11 or 12 of clockpulses of frequency Fc and successive counters 13, 15 which divide the clock frequency by integers M, N to produce a command waveform of frequency Fc/M.N, the first stage 16 of the second counter 15 comprising an add/delete circuit which receives command pulses from an interpolator unit 17 and correspondingly adds or deletes one pulse at the input of the second counter to shift the phase of the command waveform by Œ2#/N, and the command waveform being fed to one side of a phase discriminator 21 which also receives a feedback signal on line 22 from an electro-mechanical system coupled to a controlled member e.g. a tool slide and generates a corresponding error signal to correct the slide position via a servo 23 to reduce the error to zero, a setting unit 33 allows the value of N to be varied to give different resolutions for the same electrical pitch. Suitable selection of parameters Fc, M and N allows inch or metric increments of movement of the slide to be obtained with a single inch resolver 25. As described the three parameters are varied together to keep the command frequency Fc/M.N constant. The slide is driven by an inch leadscrew 24, or a metric leadscrew may be used with suitable gearing 26, 27 between the screw and the resolver 25. The latter is energized by quadrature signals at the command frequency, derived via a further counter 29 set to divide by the same value of N as the counter 15. Normally inoperative dividers 20, 32 allows the electrical pitch to be multiplied by eight if desired. The manner of adjusting M and N is described Fig. 2, (not shown).

Abstract: 390,760. Adjusting wireless apparatus. BAMBRIDGE, F. E. A., 5, Argyle Road, Whitstable, Kent. Oct. 27, 1932, No. 30172. [Class 37.] In order to facilitate tuning to any one of a number of predetermined wave lengths, a single detent is mounted for manual movement relatively to a number of selector plates on the tuning shaft, so that rotation of the shaft will be arrested at a position corresponding to a predetermined wave length. A number of selector discs 1 are adjustably mounted on a spindle 2 coupled to the shaft 2a of the usual tuning means. The discs 1 are, with the exception of the end disc 1a, formed with notches 4 with which a detent 5, Fig. 2, is adapted to co-operate. The detent 5 comprises a leaf spring secured to a carriage 6 slidable along a rectangular bar 7 by means of a handle 8. The bar 7 is pivoted in bearings 9, but is prevented from rocking except in the zero position of the spindle 2 by the engagement of an arm 11 with a cam 12. The handle 8 projects through a slot 13 in the casing, which slot is comb-shaped with a tooth corresponding to each of the discs 1. Each disc 1 is adjusted on the spindle 2 so that engagement of the detent 5 with the notch in the disc occurs when the spindle is adjusted to tune in a certain station. The disc is fixed by means of a set screw 3. The name of the station is indicated on a scale opposite a pointer 17 carried by the handle 8. When it is desired to tune in a station the spindle 2 is rotated to the zero position and the handle 8 is rocked so as to become disengaged from the comb teeth and is moved along the bar 7 until it is opposite the desired disc 1, the pointer 17 indicating the desired station. The spindle 2 is then rotated unti the detent 5 engages the notch in the selected disc. When the detent 5 engages the disc 1a that has no notch, tuning to any wavelength may be effected, a graduated scale on the end disc 1 being visible through an aperture in the casing. The selector discs need not necessarily be arranged side by side, nor need they constitute the movable part of the device.
