Abstract: 1516836 Shock absorber base valve assemblies; valves JONAS WOODHEAD Ltd 18 Aug 1975 [22 Aug 1974] 37012/74 Headings F2S and F2V The base valve assembly of an hydraulic shock absorber comprises a valve body 32 having a flow passage 36, and a bodily movable annular valve closure member 40 which is resiliently biased to close the flow passage and is guided by an integral projection 46 on the valve body. Flow in the opposite direction through the base valve assembly is via passages 52 in the projection 46, an annular space around a central pin 50, and a sleeve valve member 54. The valve body 32 and the projection 46 are formed as a single sintered component. A member 48 secured to the projection 46 provides an abutment for an annular spring 42 biasing the valve member 40. The spring 42 is a flat ring bent about a diameter.

Title: Improvements in or relating to polyethylene film
Inventor: FIELDS CHARLES MARION
IPC: C08L23/06
Filed: 1959-11-02
Abstract: Polyethylene film having a tendency to cling to smooth surfaces is made by uniformly blending high or low pressure polyethylene with from 5 to 20% by weight of paraffin oil or liquid petrolatum (B.P. range 150- to 300 DEG  C.) and then extruding as a film.  In an example polyethylene powder is fluxed at 210 to 230 DEG  F. and mixed with mineral oil in a heated Banbury mixer.  The mix is set up in slabs, is comminuted, ground or pelleted and is then extruded to give film which may range from 1/4 to 20 mils thick.  The extruder may have a slot opening or may be of the type giving an enlarged and elongated bubble which is subsequently cut to a film. The film may be used in packaging or wrapping applications.

[Also in Groups XIX, XX and XXXVIII] A device for accurate measurement of lengths or angles or speeds, or for checking uniformity of rotation comprises a magnetic tape or layer upon which has been recorded a trace of uniformly varying intensity, a pickup head being arranged to respond to the variations as these are presented in succession to it by relative unidirectional movement between the tape and head. The impulses received are passed to a counter to give a measure of such movement. If the movement is inadequate to operate the head the latter may be oscillated or rotated relative to the tape (see Group XXVIII). The device may be used for controlling movement of parts of machine tools as by producing a machine stopping signal after a given count has been reached. Reference has been directed by the Comptroller to Specification 791,902.

Abstract: 927,743. Variable speed friction gearing; toothed gearing. AVCO CORPORATION. Oct. 25, 1961 [March 21, 1961], No. 38179/61. Classes 80 (1) and 80 (2). In a toroidal disc transmission having opposed coaxial disc with an adjustable roller between them, the roller mounting means is supported in slots in the legs of a yoke member such that the roller precesses as it is steered by the yoke member. An input shaft 14 carries two driving discs 10, 12, the disc 10 being axially located on the shaft and the disc 12 being axially loaded by a spring 68 to provide driving connection for two pairs of rollers 20 and 26 between the driving discs and an idler disc 16. The rollers 20 are rotatably mounted on part spherical members 106 mounted in contoured portions of yokes 80 which are rotatable, to steer the rollers, about a pivot 82 by arms 92 engaged by a pin 98 in a control rod 96. The spherical members 106 are located in the yokes 80 by spaced pins 110, 112 engaging slots 114 in the yoke legs with relative freedom, the slots being disposed at an angle to the axis of the shaft 14 to cause the rollers to process when the yokes are rotated. The rollers 26 are carried on two arms of a cruciform member 36, the other arms of which are rigid with a fork member 32 formed on the driven shaft 34. The epicyclic gearing formed by the discs 10, 16 and rollers 26 produces variable speed forward or reverse rotation of the output shaft according to the adjustment of the rollers 20.

IPC: G03C7/06
Abstract: 385,680. Filters for lenticular-screen colour photography. KELLER-DORIAN COLORFILM CORPORATION, 522, 5th Avenue, New York, U.S.A. Sept. 29, 1931, No. 27155. Convention date, Dec. 15, 1930. [Class 98 (ii).] The juxtaposed colour-elements of a selecting- filter used in the lenticular-screen process of colour photography are made of transparent plates of rigid material unaffected by light, such as glass or quartz, coloured in the mass, and the elements differ in thickness either to allow them to transmit the same percentage of light of their respective colours or, in taking photographs, to compensate for the sensitiveness of the photographic emulsions for the different colours. When the filter is employed with oblique rays, transparent compensating plates are superimposed on the elements to render uniform the thickness of the filter as a whole. One or both sides of the filter may be protected by a transparent plate as of glass. The middle coloured element may have a smaller area than the others to compensate for loss of light due to the obliquity of the rays proceeding from the outer colour elements of the screen to the lenticular elements of the film. The elements may be cemented together, or be provided in known manner with overlapping bevelled edges to prevent the passage of white light between them. Fig. 1 shows a filter intended for use with parallel rays, comprising red, green and blue elements 4, 5, 6 of different thickness held in position in a ring 1 by a stepped ring 7 secured by a screwed retaining ring 11, the adjacent edges of the elements being bevelled. A modification is also described in which non-bevelled elements are cemented to a glass plate. Fig. 5 shows a filter for taking photographs, comprising coloured elements 14, 15, 16 of different thickness with compensating transparent plates 23, 24 for rendering the thickness of the filter uniform, and cemented-on cover plates 20, 21 of glass, the whole being held in a mounting-ring 21a by a screwed retaining ring 21b. A similar form is described for use in a projector. Data are given for constructing the two last-mentioned forms of filter from special Corning and Schott glasses. Reference is made in the Specification to selecting-filters of gelatin coloured in the mass ; to a method of protecting such filters from the humidity of the air by coating the edges with a layer of paraffin; and to filters made of glass coloured on the surface only.

Title: Temperature-controlled gas humidifier for a medical ventilator

Abstract: 1294808 Humidifier for respiratory apparatus PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 Aug 1971 38979/71 Heading A5T [Also in Divisions B1 and G3] A gas humidifier for a medical ventilator comprises a "gas-over-hot-water" vaporisation chamber 1, means 5 for heating water contained in said chamber, an electrical temperature-sensing device 11 located near the patient end of a gas supply line 6 arranged for feeding humidified respiratory gas from the chamber to said patient, and water heater controlling means 12 operable upon the temperature sensed by said sensing device whereby said temperature is maintained at a predetermined level. Operation. Respiratory gas is passed from inlet 2 over the hot water in the chamber and thence to outlet 3 after having picked up water vapour. The gas is then fed via the flexible supply line 6 to the inspiratory gas inlet 7 of a Y-piece 8 and thence to a facemask or tracked tube via connection 9. The temperature-sensor 11 is located in the Y-piece 8. The sensor, preferably a thermistor, is electrically connected to a comparison device 12 via a plug and socket 13 which enable the facemask and supply line to be removed from the vaporisation chamber if necessary. A temperature-setting control device 14 is connected to the input of the comparison device 12, the output of the latter device being fed to a switching control unit 15 used for controlling a heater power supply switching arrangement 16 which comprises a triac in the supply path of the heater power supply to heater 5. The comparison device, preferably a differential amplifier, compares the temperature-sensing and temperature-setting signals and gives an output if the temperature sensed by sensor 11 is lower than that of the setting control device 14. If the temperatures are equal then no output signal is given and the switching control 15 no longer provides triggering pulses to the triac 16, and hence the current supply to the heating element 5 is switched off. In order to protect the patient a fault detector 18 is connected to the sensor leads at 19. If a fault is detected, detector 18 inhibits switching control 15 via lead 21 and prevents operation of the heating element. Also, a water temperature detector 22, such as a bimetallic switch, senses overheating in the chamber and causes operation of the detector 18.
