Abstract: 1,228,842. Variable rate suspensions. REGIE NATIONALE DES USINES RENAULT, AND AUTOMOBILES PEUGEOT. 16 May, 1968 [17 May, 1967; 23 Nov., 1967; 24 Nov., 1967; 30 Jan., 1968], No. 23445/68. Heading B7D. A vehicle suspension comprises a supplementary spring which is maintained under stress in a state of unstable equilibrium when the suspension occupies its mean position and opposes the action of the main springing when the suspension departs from the mean position to provide a progressively increasing total spring rate, and a servo-mechanism which maintains correspondence between the equilibrium position of the supplementary spring and the mean position of the suspension when the load carried by the vehicle varies. Fig. 8 shows a supplementary spring compressed between two abutments, one connected by pivot means 5 to a casing 6 and the other connected by pivot means 4 to a lever 1 which is linked to a suspension member so as to oscillate about pivot means 2 as the suspension deflects. In the mean position the lever 1 is aligned with the pivot means 5, 2 but when the suspension deflects in either direction the spring exerts a turning moment on the lever 1. In order to align the pivot means 5, 2 with a new mean position of the lever 1 when the vehicle load varies, the casing 6 is rotated about the pivot means 2 by an electric motor 30 which drives a threaded shaft 28 engaged by a nut E on the casing 6. The motor 30 is controlled by switches sensitive to the suspension level or the alignment of the supplementary spring. Operation of the motor every time the suspension deflects during running is prevented by hydraulic damping means applied to the switches or by bimetallic thermal switches in the motor control circuit. The motor 30 may alternatively be controlled manually, departure of the supplementary spring from the equilibrium position being indicated to the driver by a warning lamp. In another embodiment, Fig. 16 (not shown), an hydraulic servomotor adjusts the equilibrium position of the supplementary spring. In Fig. 3 (not shown) a supplementary spring is connected to the lower of two transverse suspension arms independently mounting a steerable wheel. In Fig. 4 (not shown) a supplementary tension spring is connected to a longitudinally-extending suspension arm. In Fig. 6 (not shown) a single supplementary spring is connected between inward extensions of respective transverse links suspending a pair of steerable wheels, and in Fig. 7 (not shown) a supplementary spring is connected to the centre of an anti-roll bar.

Abstract: 1,250,480. Dry-cleaning. M. R. BURGER. 25 Nov., 1968 [7 March, 1968], No. 11187/68. Heading D1A. When, after the dry-cleaning of a batch of textiles, the bulk of the solvent has been removed as liquid, the remaining solvent is evaporated and removed from the cleaning chamber 100 after which it is in succession compressed, cooled and expanded and thus condensed. Solvent is supplied from tank 102 to chamber 100 to a level determined by one of the devices 104a or 104b, the textiles being held in a perforated rotary drum within chamber 100. The solvent is then circulated by pump 106 through filter 110, built up from powder before cleaning commences, chamber 100 and button trap 108. The flow is restricted to produce cooling either by valve V6 or an orifice at the pump outlet. After cleaning, chamber 100 is drained and further liquid is extracted by centrifuging. The solvent/air mixture in chamber 100 is then removed by compressor 114 which delivers it through heat exchanger 118 and expansion orifice 121 e.g. a length of narrow pipe ,to tank 102 or to a chamber leading to tank. 102 where the solvent condenses. The air returns to chamber 100 through heater 122. Heat exchanger 118 is a finned pipe coil air cooled by fan 126. Preceding orifice 121 is a valve 120 which does not open below a prearranged minimum pressure to ensure sufficient cooling. During solvent recovery, alternating centrifuging and low speed rotation may be repeated. Sludge from the filter 110 may be dumped in still 130 where the solvent is recovered. Monofluorotrichloromethane (CFCl 3 ) is preferred as solvent but monofluorodichloromethane (CHFCl 2 ) and trinuorotrichloroethane (CFCl 2 -CF 2 Cl) may be used.

Abstract: 1,259,253. Controlled frictional igniter. L.A.R.B. DE LA ROCHE. 26 Aug., 1970, No. 40965/70. Heading F4F. A frictional igniter comprises a knurled wheel 8 bearing on a metalliferous compound or flint 10, the wheel being rotatably connected to a helical torsion spring 12 which is pretensioned by a setting knob (3) with pawls 26 and engaging teeth 24 forming ratchet means, is releasable by actuation of a trip lever 5, and is controlled by means limiting the rotation of the wheel at each actuation to a predetermined value sufficient to produce a plurality of sparks. Knurled wheel 8 is fixed to a rod 7 encased in sheath 6 and casing 4, and is rigidly coupled with members 15 and 16 and radial blades 30a, 30b, 30c which are engageable with abutment members 33 and 34 on lever 5. The lever 5 has a resilient blade 35 and normally member 34 prevents blade 30a and hence rod 7 from rotating (as in Fig. 4), but on depression of lever 5, the blades and rod 7 are urged by spring 12 to rotate in the direction of arrow 42 one-third of a revolution until blade 30c abuts member 33, thus producing a shower of sparks. On releasing lever 5, blade 35 resets the device so that it can be reused many subsequent times before spring 12 becomes untensioned, necessitating operation of the rotary setting knob (3). A cam-operated presser lever 45 with pivot-pin 46 and lever 52 normally presses flint 10 against wheel 8 but, on rotation of lever 52, is released and allows the flint to be replaced

Abstract: 1,259,263. Gas blast circuit breakers. BROWN BOVERI & CO. Ltd. 16 Feb., 1970 [18 Feb., 1969], No. 7281/70. Heading H1N. A gas blast circuit-breaker comprises a highpressure gas chamber 6 having gas blast outlets 2d controlled by a slidable cylinder 7 with corresponding peripheral orifices 7a and operated by an insulated push-rod 8. The highpressure gas released enters an upper chamber 2b and hence causes a drive piston 11 to move downwards and so operate a mechanical linkage 12a, 12b, 12c. Movable nozzle contact 5 is released from fixed contact 4 and toggle linkage 13 assumes a second set position. The piston 11 moves within an apertured cylinder 10 movable by the piston within a compartment formed in the housing 2. Four axially spaced lateral ports 9 are provided in the wall of the compartment to correspond with cylinder ports 9<SP>1</SP> in one of the cylinder positions. Upward movement of the push-rod 8 from the open circuit-breaker position of Fig. 1b (not shown) provides a highpressure blast to the lower face of the piston 11 through the lowest port 9 causing the breaker contacts to close. The lower part of the housing 2 is maintained at a low pressure by a compressor, as with the nozzle contact open the high-pressure blast passes through the nozzle and tends to prevent a pressure differential occurring across the piston. A compressor, which may be both pressure and temperature controlled, may return gas from the lower pressure zone to the high pressure chamber.

Abstract: 1,265,986. Superconductor lasers. GEORGETOWN UNIVERSITY. 25 Sept., 1969 [30 Sept., 1968], No. 47277/69. Headings H1C and H1K. A superconductor radiation source comprises a tunnel junction in the form of a thin insulating layer between a normal metal and a superconductor. Single electrons tunnel from the normal metal into the high uncondensed energy level in the superconductor and decay to a lower condensed energy level emitting radiation, the superconductor being shaped and dimensioned to form a resonant cavity for the radiation. Dual particle tunnelling directly to the low condensed energy level, which inhibits lasing action, is reduced to an insignificant level by means of a 5  oxide layer. As shown, Fig. 1, a normal metal rod 12 is provided with a tapered end portion 14 which is tipped with a thin (5 ) layer of insulating material. A superconductor rod 18 having a reduced end section 16 is arranged in contact with the oxide layer to form a tunnel junction. The rods 12 and 18 pass through insulators 28, 24 in a hollow metal radiation collecting sphere 20 having a quartz window 30 through which the radiation emerges. The rods may also be mounted in a waveguide, Fig. 2 (not shown), and one wall of the waveguide may replace the normal metal rod, Fig. 3 (not shown). The surface of the superconductor adjacent to the junction is roughened by etching or pitting to prevent emission of phonons and the dimensions are selected to be multiples of half the wavelength of the radiation and requirements for their minimum values which depend on the apparent refractive index of the superconductor are given. The surface of the superconductor reflects a very high proportion of the radiation due to the high apparent refractive index so that no mirrors are required to achieve lasing at wavelengths in the far infra-red and microwave region. A sphere containing the radiation emitting junction may be mounted in a cryostat from which the radiation is extracted by means of a tube containing windows of germanium or quartz separated by a vacuum, or by means of a light pipe or waveguide. The superconductor material may be Ta or Nb and the rod may be produced by turning on a lathe followed by etching and anodizing. The junction may be formed by bonding the normal metal and superconductor rods under pressure and the junction shape may be a point contact or a strip. The insulator may be applied to the normal metal or to the superconductor and may be electrodeposited as can be the normal metal and the superconductor material. The wavelength of the radiation may be adjusted or modulated by varying the current or by changing the temperature of the junction. Other frequency bands may be covered by utilizing a frequency multiplier.
