Abstract: 582,129. Valve circuits for wireless reception. SCOLES, G. J., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Sept. 8, 1941, No. 10141. [Class 40 (v)] A detector circuit of the cathode follower or infinite impedance type comprises a triode or screen grid valve with the input applied to the control grid and including a load resistance in the cathode circuit and a limiter diode connected to the cathode through a high resistance and having its cathode positively biassed. The Figure shows a detector V1 having load resistance R, R1 and having its cathode connected through resistance R2 to the anode of a diode V2, the cathode of which is biassed from potentiometer R3, R4.

Title: Improvements in or relating to electric selective signal-responsive devices
IPC: H02J13/00
Filed: 1942-07-22
Abstract: 555,398. Electric signalling systems. GENERAL ELECTRIC CO., Ltd., and SMART, N. C. July 22, 1942, No. 10220. [Class 40 (i)] In a system in which the contact chosen by a selector switch depends on the time interval between two signal impulses received over a power circuit, the first impulse, by operating a relay. R, starts the self-starting synchronous motor of the switch and, assuming that it has the prescribed minimum duration, causes-the changeover of cam springs CS. The motor then stips until the relapse of R on the termination of the impulse whereupon the switch is again driven. The second impulse stops the switch on the required terminal and causes operation of the selected device and the cessation of the impulse causes the switch to be driven back to normal. This arrangement prevents effective operation of the selector by stray impulses.

Title: Process of working a metal tube
IPC: B21C37/06
Filed: 1972-03-06
Abstract: 1388431 Making tubes R G JACKSON 6 March 1972 10284/72 Heading B3A A metal tube is worked by cold stretching the tube to reduce its internal diameter and then cold working the tube to effect further reduction in its internal diameter. After stretching the tube below its recrystallization temperature, the tube is drawn or its internal diameter expanded by a mandrel. The tube may be heat treated after drawing and heat treated below its recrystallization temperature after stretching and between drawing steps. The cycle of stretching and drawing operations may be repeated. The tube can be of Fe, Cu, Al, Zr, Ti, Ni, Co, Ag, Au, Pt and their alloys. In an example, a welded tube of 18% Cr, 8% Ni stainless steel is gripped at both ends and stretched to produce a 25% reduction in area. Subsequently, the tube is drawn in four steps, using a mandrel only in the first step and with no intermediate heat treatments, to produce a total reduction of area of 80% and a tensile strength of more than 200,000 p.s.i.

Filed: 1973-03-02
Abstract: 1426525 Vehicle steering linkage BAYERISCHE MOTOREN WERKE AG 2 March 1973 [2 March 1972] 10367/73 Heading B7H In a motor vehicle of the type having a steering linkage including track rods 5 for transmitting steering movements from a steering member in the vehicle frame to track arms 7 attached to stub axle carriers 6, the track rods 5 are each connected to a track arm 7 by a coupling member 8 of which the joints connecting the latter to the track rod 5 and track arm 7 are pure pivot joints turning about two pivot axes in such a manner that one axis I extends substantially horizontally in the longitudinal direction of the vehicle when there is no lock on the wheels 1 while the other axis II extends in a substantially vertical transverse plane at an angle of inclination # to the swivel axis 9, the point of intersection P 0  of axis II with the horizontal plane containing axis I lying on the outside of axis I, and the other end of the track rod 5 being connected to the steering member in a manner permitting rotation of the track rod 5 about a horizontal transverse axis III. The above described arrangement allows the maximum lock of the wheels 1 to be increased before the turning moment of the track rod 5 reaches zero. In a first embodiment (Figs. 1, 2) the coupling member 8 is pivoted to the track arm 7 about axis I and is pivoted to the upturned end of track rod 5 about axis II. The track rod 5 is connected to steering member 4, e.g. a steering rack, by a ball-and-socket joint 10 which permits rotation of the track rod 5 about axis III. In a modification (not shown) the track rod 5 has a down-turned end and the coupling member 8 is inverted. In a second embodiment (Fig. 4) the coupling member 8<SP>1</SP> is pivoted to the track arm about axis II and is pivoted to the track rod 13 about axis I. The track rod 13 is connected to the steering member (e.g. a central track rod 12 operated by steering mechanism 11) by a joint 15 which permits rotation about two axes 16 and 17. The axis 16 coincides with axis III<SP>1</SP> while a axis 17 allows the track rod 13 to follow the up and down movements of the wheel 1.

Abstract: 343,797. Spraying-apparatus. ELDER, D., 2535, Durant Avenue, Berkeley, California, U.S.A. April 1, 1930, No. 10371. [Class 69 (iii).] A sprinkler system of the kind in which a sprinkler head is arranged below the level of the ground and projected, therefrom by the pressure of the water is so arranged that the nozzle is closed in the retracted position and remains closed until fully projected when it is opened, but is again closed before being returned to the retracted position. AT-piece 2 mounted on a main 1 carries a tubular member 4, within which is slidably mounted a shouldered tubular member 8, a spring 14 being interposed between the shoulder 12 and an inturned flange 6 on the tube 4. Within the tube 8 is a rod 18 carrying at its upper end a valve 17 held against a seat 10 by a spring 21 slightly stronger than the spring 17. The spring 21 bears against an adjusting nut 20 on the rod 16 and an inturned shoulder in the tube 8. A helically grooved collar 19 centres the rod 18 and also gives a swirl to the water leaving the nozzle. In a modification the valve head is provided with a screwed slotted sleeve engaging the upper screwed end of the rod 18, the flange 14 is replaced by a centring pin, and the spring 21 engages a pin passing through the rod 18 which engages slots in the casing to prevent rotation. A strainer may be provided to prevent access of dirt &c. Specification 248,371, [Class 69 (iii), Spray-producers &c.], is referred to.

Title: An arrangement for the automatic control of the efficiency of transmitting systems, particularly for high frequency transmitting systems
IPC: H04B7/005
Filed: 1928-04-05
Abstract: 289,050. Siemens & Halske Akt.- Ges. April 21, 1927, [Convention date]. Duplex signalling; fading, preventing; automatic gain control. - Relates to means for preventing " singing " between the outgoing and incoming lines of a duplex circuit, where, as in a combined wired and wireless system, a part of the circuit has a fluctuating conductivity (due to fading effects). According to the invention provision is made to ensure that the circuit as a whole has a minimum overall attenuation bv utilizing a control current the frequency of which lies outside the normal range of signalling frequencies, and by applying such control current to regulate the overall amplification factor at a point along the transmission line which precedes the entry of the combined control and signalling currents on to the regulating apparatus, so that alteration of the amplification ratio influences both currents simultaneously. As shown in Fig. 2, a special control frequency, lying outside the normal speech frequencies, is imposed by a generator O upon the outgoing radiation. In the receiving circuit, this control frequency is diverted by filters S2, S3 into a branch relay R, where it controls a motor M which automatically adjusts the setting of a potentiometer P so as to ensure that the strength of the received signals is maintained below the point at which a regenerative action would occur. A constructional form of relay is shown in Fig. 3. If the signal voltage grows too strong, the relay R2 is closed, the relay R3 is simultaneously opened, and an electromagnetic clutch on the wheel V reverses the previous direction of the shaft T, which carries the adjustable tapping to the potentiometer P, Fig. 2. For weaker signals the relay R1 connects the differential wheel W to the driving motor M, so that the potentiometer setting fluctuates about a mean point determined by the sensitivity of the relay R2. In the alternative arrangement, the same effect is secured by using only one relay. The generator O, Fig. 2, can be used directly to calibrate the sensitivity of the receiving relay.
