Filed: 1972-12-19
Abstract: 1409540 Lamps COMPTEURS SCHLUMBERGER 19 Dec 1972 [23 Dec 1971] 58670/72 Heading F4R [Also in Division H5] An infra-red radiation emitter comprises a casing 26 with a flat infra-red transparent window 12, a sleeve 6 with a closed end 8, perpendicular to, and in contact with the window at a point so as to reduce conduction heat losses, the sleeve radiating in the infra-red when heated by an electrical resistance heating wire 2 wound on refractory tube 4, and means (conical depression 10, spring blade 22, centering block 16, cement 30, 28) for maintaining the window and sleeve in contact and for keeping the longitudinal axis of the sleeve from moving. The sleeve 6 and tube 4 are coaxial. Reflector 36 is of stainless steel. Window 12 is of silicon or germanium. By enclosing the heating wire within the radiation producer, the window is prevented from darkening due to sublimation from the heating wire. By immobilizing the radiation producer, a very stable radiation flux is emitted.

Abstract: 1329029 Self-heating depilatory COLGATEPALMOLIVE CO 10 Dec 1970 [19 Dec 1969] 58691/70 Heading A5B A self-heating depilatory composition comprises two parts which are held separately until required for use when they are mixed to form a depilating composition with the evolution of heat from an exothermic chemical reaction. In particular, one part may contain thioglycolic acid and the other an alkali such as sodium hydroxide which reacts exothermically therewith to form a salt such as sodium thioglycollate. A surfactant, e.g. a triethanolamine alkyl sulphonate and additional depilating agents may also be present. Preferably, the two parts of the composition are packaged in a twocompartment "aerosol" container from which they are dispensed by a compressed gas, e.g. a 1:7 propane: isobutane mixture, as a foam.

Title: One-way valve assembly
IPC: F16K15/14
Filed: 1979-05-29
Abstract: A valve assembly comprising a housing having a valve chamber, an inlet at one axial end of the valve chamber and an outlet at the opposite axial end of the valve chamber. A rib surrounds the inlet opening in the chamber. A valve element is mounted in the chamber comprising a generally disc-like body portion having a top face and a bottom face, and a plurality of pedestals depending from the bottom face. The top face of the valve element confronts the rib and the terminal ends of said legs abut the opposite axial end wall of the valve chamber. The axial height of the valve element is slightly greater than the axial depth of the valve chamber between the rib and opposite axial end wall so that a predetermined pressure at the inlet greater than pressure at the outlet is required to open the valve element. The peripheral wall of the valve chamber has at least one flow passage to permit flow from the inlet to the outlet when the valve element is lifted by a predetermined pressure at the inlet.

Title: Air treatment device
IPC: A61L9/00
Filed: 1980-01-22
Abstract: An air treatment device, primarily a deodoriser for use in a refrigerator, comprises a receptacle containing a predetermined charge of a treatment substance, such as activated charcoal comprising a hollow central body 1 having an annular peripheral flange 4, 4' at each end arranged to clip into a groove formed in a corresponding end cap or plate 2, 3 to hold the plates on the body 1. Two foil elements 7 and 7' with a high permeability to air, a high resistance to humidity, and capable of retaining particles of the order of a micron, are held between the end plates and the corresponding ends of the central body. Each end plate has apertures 6, 6' to allow air to permeate into and out of the body through the foils, the activated charcoal being retained in the body by the foils. The charge is such that it fills the body 1 to the horizontal median plane when the receptacle rests on its side, and in this way ensures the largest possible contact surface area between the air to be treated and the charge. <IMAGE>

Title: Method for the manufacture of a pole shoe for electrical machines
IPC: B21J5/08
Filed: 1980-03-05
Abstract: The present specification discloses a method for the manufacture of a pole shoe for electrical machines by the non-cutting shaping of a rolled- section blank. In known non-cutting methods the blank is fully subjected, during each shaping stage, to the forming forces simultaneously both in the region of the pole shoe core and in the region of the pole horns. The method of the present invention is performed by means of a progressive tool (1, 2,) (8, Figure 1, not shown) in two shaping stages, or in a device comprising two upsetting dies (24, 26). In the first shaping stage the core region (12) of the pole shoe is fully formed, and, in the second shaping stage, the pole horns (18, Figures 3,6, not shown) are fully formed by pressing. According to this method the forming of the core region (12) and the forming of the pole horns (18) are performed by separate applications of force, whereby the forming forces may be substantially reduced. <IMAGE>

Patent GB-2050730-A (GB)
Title: Television horizontal oscillator synchronizing phase detector
IPC: H04N5/12
Filed: 1980-05-08
Abstract: A phase-lock (AFPC) loop maintains a horizontal oscillator 450 in synchronism with horizontal synchronizing signals in the presence of noise and includes a phase detector (30). The oscillator 450 output signals exhibit successive transitions of first and second polarities. During the vertical synchronizing and equalizing pulse intervals, the frequency of the synchronizing signals applied to the AFPC phase detector is greater (doubled) than during the vertical scanning interval. The increase in frequency may decrease the AFPC loop gain or unsynchronize the loop. This effect is overcome by selectively controlling the coupling of the oscillator signals or of the synchronizing signals to the input terminals of the phase detector, or the coupling of the phase detector output to the oscillator control input, so that the phase detector controls the oscillator in response to synchronizing signals occurring in substantial time coincidence with only first polarity outputs of the coupled oscillator signals. The invention is of particular importance when the television is used with a video tape recorder. <IMAGE>
