Title: Differential thermostat
IPC: G01K5/62
Filed: 1926-04-30
Abstract: 251,981. Dubois, R. May 5, 1925, [Convention date]. Arc lamps.-An apparatus for controlling the position of the crater of an electric arc relatively to the focus of the lens of an optical projector comprises at least two bimetallic strips which operate to make or break an electric circuit when subjected to heat radiations of unequal intensity. A bimetallic strip 1 is mounted in a holder 6 pivoted at 7 and provided with a vertical extension to engage with a screw 9 for adjusting the position of the strip. A second bimetallic strip 2 is mounted on an insulated screw 10, and an electric current flows through the two strips in series when in contact. The strip 2 carries a curved member 3, and the two contacts 4, 5 are adapted to separate when the strip 1 is heated by radiation. Alternatively, the contacts 4, 5 may be adapted to complete the circuit in these circumstances. In a modification, Fig. 3, three strips 12, 13, 14 are arranged edge to edge, and are provided with contact studs as in Fig. 4, which are adapted to contact by lateral movement. In Fig. 3, the thermostat is placed so that the arc 11<2> represents the correct position of the projected beam. An advancement or withdrawal corresponding to the arcs 11<3>. 11<1> results in a differential heating of the thermostat, and adjustment of the arc.

Filed: 1961-03-29
Abstract: 955,733. Rackets. J. R. LACOSTE. March 29, 1961 [March 30, 1960], No. 11598/61. Heading A6D. In a tubular metal frame for a tennis or like racket of dumb-bell cross-section, the strings are attached to loops extending round the frame. As shown, the loops may be formed by winding a piano wire 17 spirally round the frame, the turns of the wire being located by a notched spacer strip 18. The strings are looped round the turns of wire 17 in the inner groove corresponding to the groove 8. The strip 18 may form part of the completed racket or may be removed. In a modification (Figs. 9 and 10, not shown), the strings are attached to an intermediate sinuous wire member which is bound to the inner periphery of the frame 5 by wire 17. Instead of being in spiral form, the wire may be applied to the frame in half hitches (Fig. 11, not shown). In other forms (Figs. 12-14, not shown), the wire is replaced by metallic rings which may be located by tubular or notched spacers. Metallic rings formed with inward projections (Fig. 15, not shown), are spaced by means of blobs of plastic on solder in groove 8. The frame may be made of hard chromium plated steel tube. Specification 955,732 is referred to.

Abstract: 701,730. Hydraulic shock absorbers. CHRYSLER CORPORATION. May 9, 1952 [May 29. 1951], No. 11767/52. Class 108(3) . An hydraulic damper comprises a piston E having a notch-like orifice H providing restricted flow in each direction between upper and lower cylinder chambers F and G defined by the piston E and a valve 69 providing free flow on rebound from the reservoir D to the chamber G and restricted flow by virtue of a notch-like orifice J in the opposite direction, the liquid flow resisting characteristics of the orifices H and J being so proportioned relative to each other that on the compression stroke passage of liquid is sufficient to maintain the chamber F full of liquid. The piston has six axial passages 57 which provide no restriction to liquid flow and open into an annular channel 53. A resilient disc 24 seats on the upper face of the piston and is formed with notches 23, Fig. 4, which connects the channel 53: with the chamber F. Sufficient pressure in chamber G results in lifting of the disc 23 against the action of resilient discs 51, 52 which may be prestressed. The orifice J is provided by a notched disc 72, Fig. 5, carried by the valve 69. The orifices H and J may alternatively be provided by notches formed in the seating on the upper piston face and the seating of the valve 69, Fig. 6 (not shown). The notches. in this case have sloping walls, Figs. 9, 10 (not shown), and are formed by a coinpressing operation. The channel 53 may be omitted and in this case the disc 24 is of spoked formation. The ratio of the areas. of the orifices H and J is preferably equal to the ratio of the area of the chamber F to the area of the piston rod 28. The area of orifice H may vary between .27 per cent to .4 per cent of the area of chamber F. Dimensions of a shock absorber suitable for a vehicle front suspension and curves relating to performance characteristics are given. Specification 687,049 is referred to.

Title: Improvements in or relating to frequency modulated carrierwave receivers
IPC: H03G3/34
Filed: 1964-03-25
Abstract: 988,507. Radio receiving circuits. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. March 25, 1964 [March 30, 1963], No. 12537/64. Heading H3Q. In a frequency modulation receiver a control voltage, e.g. for muting purposes or control of motor tuning, is derived from a supersonic pilot tone which is frequency modulated upon the incoming signal within the receiver itself. The local oscillator 4 is frequency modulated with the frequency fs derived from a source 10, this frequency being separated from the output of the discriminator 6 by means of a filter 8. In one embodiment (Fig. 1, not shown), this is then fed directly to the control stage 9. To prevent incorrect operation during tuning, on one or other of the side " flanks " of the transmission, the output from filter 8 may be passed over phase-shifter 11 to a phase-sensitive rectifier 12 which receives its second input from the source 10, so that control stage 9 is only operated at the correct tuning point. In a further embodiment (Fig. 3, not shown), the pilot frequency is generated by self-oscillation in the receiver, the source 10 being omitted and a feedback loop provided by connecting the output of filter 8 over a phase-shifting circuit to frequency-modulate the local oscillator 4.

[Also in Division C1] In the deposition of layers of semi-conducting or insulating material from the gas phase on to heated semi-conductor crystals uniform layer thickness is achieved by passing a reaction gas which decomposes thermally to give the deposited material over the surface of the substrate during a first period of time in one direction and then during a second period of time in the opposite direction, the two periods being substantially equal in length and the operating conditions, other than the direction of gas flow, being substantially the same in both. Multiple flow reversals may be effected. Suitable apparatus for the process includes an elongated reaction vessel 3 with a feed pipe at each end, each pipe being connected through valves both to the gas supply 7 and to exhaust, and with means for heating a plurality of substrate wafers I, e.g. an electrically conducting plate 2 which is itself heated inductively.

Filed: 1957-04-18
Abstract: Phosphoric acid is produced by reacting phosphate rock with sulphuric acid waste liquor in an amount not exceeding that required for complete reaction, separating the solid residue, and concentrating the phosphoric acid solution.  Ground phosphate rock is reacted with liquor from steel pickling, or waste acid from the treatment of titanium ores in the production of Ti, at about 80 DEG C. and phosphoric acid is filtered hot from the CaSO4 residue, and allowed to cool to deposit crystals of acid iron phosphate, FeH4(PO4)2.  Th FeH4(PO4)2 is separated from the mother liquor, which is combined with the aqueous liquor from washing the CaSO4 residue, and the combined acid solution is concentrated.  Alternatively, the CaSO4 residue may be washed with waste liquor, which is recycled to phosphate rock treatment.
