Patent GB-647105-A (GB)
Title: Improvements relating to the colouration of sheet materials
Inventor: ALLAN JOHN
IPC: B41M1/30
Filed: 1948-05-10
Abstract: Sheets of a thermoplastic cellulose derivative are coloured by locally applying a dye soluble in the sheet-material unaccompanied by any substance insoluble in the material, simultaneously or subsequently heating the surface to be coloured to a temperature above the flow-point of the sheet material, and while it is at such temperature applying pressure by means of a polished metal plate. The dye may be applied by (1) first printing the design on to a textile fabric (e.g. cellulose acetate or cotton) in the normal way, washing and drying, and laying the fabric on to the thermoplastic sheet; paper is less suitable than textile fabrics, but other cellulose esters and linear polymers such as nylon may be used; (2) printing the design (e.g. by a screen) on to a polished metal plate, drying and applying this to the sheet; the dye is applied to the plate in the form of a lacquer (e.g. of the cellulose acetate type) all the components of which are soluble in the sheet-material; or (3) silk-screen printing directly on to the sheet and drying.  The process is applicable to rigid transparent or translucent sheets and to thin flexible films and foils.  The material may be cellulose acetate or other ester derived from one or more fatty acids of two to four carbon atoms, or may be ethyl or benzyl cellulose.  Suitable dyes are those of the azo, nitro - diarylamine and amino - anthraquinone series which have affinity for the sheet-material. Further Further effects which may be obtained are: (1) increased brightness of colour by roughening the uncoloured surface of the sheet, e.g. by pressing it against a hot plate engraved with a fine pattern; this plate may be the lower surface of the assembly used to provide heat and pressure for transfer of the colour; (2) dull areas by transferring on to the sheet alongside the areas coloured by the dye a pigment of high refractive index, e.g. titanium dioxide; this may be printed directly on to the sheet in the form of a lacquer, or printed first on to a fabric in the same manner as the dye; (3) an embossed effect derived from the fabric when this is used as transfer means for the dye.  Examples show the process applied to cellulose acetate.  According to the Provisional Specification, the process is applicable to sheets of other thermoplastic polymers, e.g. polymerized monoolefinic compounds such as polyvinyl-chloride-acetate, polyethyl acrylate and polymethyl methacrylate, and linear condensation polymers such as nylon.

Title: Improvements in or relating to cooling systems for internal combustion engines
IPC: F01P7/16
Filed: 1961-04-10
Abstract: 948,086. Temperature-responsive actuating- elements. INTERNATIONAL HARVESTER CO. April 10,1961 [July 22, 1960], No. 12811/61. Heading G1D. [ Also in Divisions F2 and F4] A valve (not shown) which directs I.C. engine coolant liquid through a cooler or through a bypass according to its temperature, is controlled by a thermally sensitive element which as shown includes a wax pellet 58 extending into a chamber 40 through which the coolant passes. On say an increase in coolant temperature, consequent expansion of the wax pellet 58 moves a piston 62 and a rod 70 to swing a lever 80 about a pivot 83, this movement being resisted by a tension spring 94 (Fig. 2 not shown). Movement of the lever 80 acts through links to move the valve. In the operation of the element expansion of the pellet presses against a flexible diaphragm 60 which transmits movement through a resilient member 60a to the piston 62 and hence to rod 70. The piston is slidable in a guide member 64 which is flanged, the flange being held between washers 44, 44<SP>1</SP> as shown. A light return spring 65 ensures that the piston assembly is held in contact with the diaphragm 60 at all times.

Title: Improvements in ultrasonic delay lines
Inventor: RANKIN ALEXANDER BRYCE CALDER
IPC: G01B17/02
Filed: 1953-05-07
Abstract: 770,397. Ultrasonic inspection devices. KELVIN & HUGHES, Ltd. May 5, 1954 [May 7, 1953], No. 12825/53. Class 118 (2) [Also in Groups XXXIX and XL (b)] Ultrasonic apparatus for measuring, e.g. the thickness of a body 45, Fig. 10, comprises a transmitter 20 of ultrasonic electric energy, input and output transducers 43, 44 in contact with the body 45 and connected respectively to the transmitter 20 and an indicating device 21, e.g. a C.R. tube, a time-delay device 9 being connected to the transmitter and indicating device in parallel with the transducers 43, 44. A further electrical connection, not shown, between the transmitter 20 and indicating device 21 enables an input pulse to be recorded in the indicating device, this recorded pulse serving as the zero of a time scale. The positions of the two reflected pulses in the time scale may then be compared and the unknown dimension of the body 45 calculated from the known time delay in the delay line 9. This line comprises an input probe 10 which contacts the surface of a wave-transmitting body 13, the materials of the probe and the body being so chosen that the velocity C 1  of longitudinal waves in the probe is less than the velocity C 2  of transverse waves in the body, the angle of incidence of waves directed into the body from, e.g. a piezo-electric crystal 16 being slightly greater than sin<SP>-1</SP>C 1 /C 2 . The transducer 16 is arranged on the sloping face 15 of the body 10 at a distance a from the junction of the orthogonal faces 14, 17. The mode of transmission employed is that known as Rayleigh waves, the delay time t being given by t=2a/C 1 +x/C 2  where x is the path length. Since 2a/C 1  is never zero there is a lower limit to the time delay. The material of the probe may be " Perspex " (Registered Trade Mark) and that of the body 13 steel or, if a higher transmission velocity is required, beryllium. If copper is used the probe may be of lead or liquid in a container (Fig. 4, not shown). The input probe 10 may also be used as a pick-up for waves reflected from the end of the body 13, the transmitter and indicating device being connected to the probe through a transmit-receive switch 40, Fig. 9. Alternatively, a second probe 11 may be used to pick up either a direct or reflected wave. The under surface of the body 13 is preferably serrated. In order to adjust the delay time the probe 11, Fig. 3, may be attached to a block 24 threaded upon a lead screw 23. A spring 26 holds the probe in a longitudinal groove 25 in the body 13. In a modification, the body 13 is bent into a circular or helical shape (Figs. 6, 7, not shown) in order to save space.

Class 73 In a labelling machine wipers acting on a bottle. placed on a rest are arranged to contact the label over a maximum area during the wiping action and to move clear for the return movement. Arcuate wipers 16 having a resilient lining 17 are carried by a pivoted mounting 15 in arms 8 mounted on a common pivot 9 of a slide movable vertically. Rollers 20 on pins 19 of the arms 8 are held by a spring 28 against either a stationary cam track 21, Fig. 5, or an auxiliary cam track 22, Fig. 1. In operation with a bottle 5 placed on an adjustable support 6, the slide rises from the position shown in Fig. 1, until an actuating member 31 disengages a latch 26 to allow the spring 28 to force in the auxiliary cam tracks 22 until the rollers 20 engage the fixed tracks 21, Fig. 5, the arms 8 moving in so that the wipers engage the bottle and as the slide descends the wipers wipe round the bottle to the position shown in Fig. 5.. Further descent of the slide causes the rollers 20 to enter recesses 30 in extensions 29 of the auxiliary cam tracks 22 thus forcing them apart until the catch 26 re-engages, thus the wipers move clear of the bottle for the return of the slide to the position of Fig. 1, with the rollers 20 engaging the auxiliary cam tracks 22.

Abstract: 252,383. Allgemeine Elektricitõts- Ges. May 20, 1925, [Convention date]. Drawings to Specification. Controlling heating systems; systems depending on static transformers.-In electrical heating or welding machines employing transformers. which may work at a high flux-density, the initial current-rush on switching in is reduced by momentarily including a resistance in the circuit. The arrangement applies particularly to arrangements including an overload cut-out which is liable to open under the current-rush. The resistance may be associated with a " preliminary " contact on the foot-operated switch or with the cut-out contacts. It may be permanently connected so as to be short-circuited by the closure of the cut-out contacts. In a modification the resistance is arranged in parallel with the cut-out coil so that the current rush cannot pass therethrough. The resistance may in certain cases be an impedance and may be constituted in part or wholly by a retaining coil on the cut-out. The resistance may be switched in by stages.
