Filed: 1954-12-10
Abstract: 757,875. Bending, storing and transporting glass. PITTSBURGH PLATE GLASS CO. Dec. 10, 1954, No. 35833/54. Drawings to Specification. Class 56 [Also in Groups VIII and XVII] Relates to the application to glass sheets of a thin coating of protective material, particularly finely divided mica, (a) in the manufacture of curved laminated windshields, and (b) in the stacking or transport of glass sheets. In the manufacture of windshields wherein two plane glass sheets are passed, in facial contact with one another, through a bending lehr whereby they are given identical curvatures, the curved sheets being then separated and a plastic inner layer inserted after which three layers are bonded together, a layer of finely divided mica is deposited on that face of one of the glass sheets which will eventually be inside. Apparatus for depositing the mica from a cloud and for removing excess mica is described. The mica layer is deposited before the sheets pass to the bending lehr and prevents the sheets sticking together. It is uneccessary to remove the mica before laminating. For stacking or transporting glass sheets finely divided mica is deposited as in the previously mentioned application and serves as a separator between the sheets to prevent damage or deterioration.
Patent GB-1148559-A (GB)
Title: Improvements in typewriters and the like
IPC: B41J11/27
Filed: 1967-08-04
Abstract: 1,148,559. Typewriters &c. INTERNATIONAL STANDARD ELECTRIC CORP. 4 Aug., 1967 [6 Aug., 1966], No. 35858/67. Heading B6F. A platen 2 for a typewriter or the like has at each end radial pins 4 for engaging perforations in paper being fed through the machine, each pin being urged radially outwards by a spring 5 and having a transverse bolt 4a engaging cam tracks on the inner edges of two plates 6, 8, which are relatively adjustable circumferentially so that the cam tracks control the retraction and projection of the pins as the platen rotates. The cam tracks on the plates 6, 8 are identical and each comprises a circular part which, if engaged by a bolt 4a, holds the associated pin 4 in retracted position and a part which extends outwardly so as to allow the pins to move to projected position. The latter part is contained within the angle α, Fig. 3a, i.e. approximately over the range in which the paper 12 contacts the platen, and the plate 6 is held by a bar 7 engaging a fork 6a thereon so that the extended part of its track is in this position. The plate 8 can be held in one of two circumferential positions by a latch 9 engaging one of two recesses 8a. In one position of plate 8, the two cam tracks coincide so that the pins 4 are projected over the range α, whilst in the other position the pins remain retracted. If the operating range α is less than 90 degrees, the plate 8 may have more than two positions to which it could be set. The part of each bolt 4a engaging the plate 8 is slightly larger than the other part so that if the catch 9 is released the plate 8 may be rotated by rotating the platen because of the friction between the bolts 4a and the plate 8.

Title: A method of and means for retaining sheet-like articles in suspension during treatment thereof
IPC: C03B35/14
Filed: 1962-09-21
Abstract: Sheets of glass are supported during treatment, e.g. in an annealing lehr, on a cushion of gas and the depth of the cushion is maintained by controlling the upward escape of gas at the sides of the cushion. This is effected by the use of battens 9, 10 which are adjustable to vary the width of the gap between them and the edges of the glass sheet.  The current of gas can be heated to assist in the treatment and a supplementary gas cushion may be provided <FORM:1029305/C1/1> above the sheet to assist in maintaining the sheet at the correct height; alternatively, a suction may be applied above the glass sheet to draw off heated gas for recirculation.  Pusher fingers 16 on endless chains may be provided for moving the sheets, or the legs supporting the treatment chamber at the exit end can be made shorter than those at the inlet end to provide a declivity towards the exit.

Classes 75(4) A daylight lighting fitting for colour comparison purposes of the kind comprising a combination of two or more electric lamps, such as low pressure mercury vapour fluorescent electric discharge lamps combined with tungsten filament lamps, is provided with means for generating ultra-violet radiation so that of the resultant total radiation of wavelengths between 3200A and 7000A, at least 5 per cent comprises wavelengths between 3200A and 4000A. The ultra-violet radiation may be obtained from a phosphor coating of barium strontium disilicate actuated by lead in the fluorescent lamps which provide part of the visible light. As shown the fitting comprises two filament lamps 4, 5 combined, in a trough reflector 1 closed by a diffusing glass 3, with two low-pressure mercury vapour fluorescent discharge lamps 6, 7 which have magnesium tungstate coatings. Two additional low pressure mercury vapour fluorescent discharge lamps 8, 9, having coatings of barium strontium disilicate activated by lead, provide the desired ultra-violet component in the range 3200Š to 4000A, each lamp 8, 9 being surrounded by a filter 10, 11 respectively to absorb the visible radiation from the lamps. The internal surface 12 of the trough is made diffusely reflecting for wavelengths down to 3200A. Fig. 2 shows the control circuit of the fitting, the pair of filament lamps 4, 5, which may be 75 watt 240 volt, being connected in parallel with each other, and in series with a 100 ohm, variable resistance 14 for control of the contribution of the filament lamps. Each pair of discharge lamps 6, 7 and 8, 9, are connected in series with each other and with a ballast choke 17, 22 respectively, each lamp having its electrodes connected through a thermal starterswitch of the resistance heated type. Fig. 3 shows, by the full line A, the spectral energy distribution of the resultant light, curve B showing that of overcast daylight. The curve A<SP>11</SP> shows the ultra-violet contribution of lamps 8, 9 which produces the distortion of curve A into closer approximation with curve B, the line A<SP>1</SP> showing the distribution which would result in the absence of lamps 8, 9.

Title: Improvements relating to apparatus for determination of moisture content, particularly in clay material
IPC: G01N5/04
Filed: 1957-11-21
Abstract: 894,553. Determining moisture content of substances. STEDHAM, M. E. C. Feb. 20, 1959 [Nov. 21, 1957], No. 36302/57. Class 97(3). [Also in Group XVIII] In a method of determining moisture content of clay or other materials in which a quantity of the material is weighed, heated to drive off the moisture, and then weighed again, the weighing, heating and the calculation of moisture content are accomplished automatically. As shown, Fig. 1, clay in a container inside a heater 9, is supported by a balance arm 7, the sequence of operation is looked after by a time switch Fig. 5 which in its first position connects up a motor 15 which via differential gear 18 drives a shaft 14 to tension spring 11 to balance wet clay in the weighing container. The balance position is recognised with the aid of a mask and a pair of photocells or phototransistors or otherwise. In the next position of the time switch, the weight of the loaded container is taken by a support, a heater surrounding the container is switched on and a motor 10 which rotates the container within the heater is energized. After a further period, the support is withdrawn and a motor 19 via the other input of the differential gear drives shaft 14 to rebalance the now dry clay. Motor 19 also drives a potentiometer X the position of which thus represents the weight of moisture driven off and shaft 14 drives a potentiometer Y the position of which now represents dry weight. These potentiometers are associated for a short time on the completion of the second weighing with a recording meter so as to show moisture as a percentage of dry weight. The container is then discharged and the potentiometers are driven to their home position under control of limit switches. It may be arranged that the paper of the recording meter is driven only when the meter is actuated.
