Abstract: 1,272,441. Colour television tubes. GTE SYLVANIA Inc. 13 Aug., 1969 [13 Aug., 1968], No. 40436/69. Heading H1D. The shadow mask 20 of a colour television tube is supported from the envelope by a number of mounting members each comprising a bimetallic plate 32 having a portion 40 attached to the mask frame 23 and a second portion 42 attached to one end of a spring 34 the other end of which removably engages a stud 38 formed on the wall of the envelope. The plate 32 is formed with a corrugation 46. Of the two layers of metal comprising the plate, that having the higher temperature coefficient (e.g. a Ni, Cr, Fe alloy) lies on the outside of the corrugation so that the plate contracts as its temperature increases and the mask moves nearer to the screen of the tube. This movement maintains the alignment between the apertures in the mask and the phosphor elements on the screen. The corrugation 46 is tapered so that the wide end 50 contracts more than the narrow end 52 whereby the movement of the spring 34 is amplified.

Abstract: 1,126,573. Storable colloidal solutions. DEUTSCHE GOLDUND SILBER - SCHEIDEANSTALT. 23 Sept., 1965 [24 Sept., 1964], No. 40641/65. Heading C1A. Storable colloidal solutions of ultra-finelydivided oxides or mixed oxides are prepared by mechanically dispersing the oxide or mixed oxide in an aqueous solution of polyethylene imine (PEI) in the form of the free base or partially or wholly in the acid-combined form, the quantity of PEI being such as to provide a solution of minimum viscosity. The oxide or mixed oxide preferably contains pyrogenically obtained silica and the acid used to completely or partially neutralize the PEI content of the solution is preferably formic or acetic acid. The necessary acid is preferably added to a paste of PEI. The amount of PEI used increases with the increasing oxide concentration in the colloidal solution and with the increasing BET surface area of the oxide used. The amount necessary to achieve the desired minimum viscosity may be calculated on the basis that the quantity of PEI in grams used is one-half of the BET surface area in square metres for the free base used alone, and one tenth of said surface area for the PEI salt used alone.

Title: Computer-printer interlock apparatus
IPC: G06M3/06
Filed: 1960-11-28
Abstract: 892,412. Counters. GILBERT & BARKER MANUFACTURING CO. Nov. 28, 1960 [Dec. 23, 1959], No. 40783/60. Class 106 (1). [Also in Group XVIII] A petrol pump can print the cost of petrol dispensed and is provided with interlocks to prevent incorrect operation. Before the pump motor 13, Fig. 1, can be energized by movement of lever 12 from vertical position, the register wheels 19 of the computer must be set by zero by knob 18. If a ticket is printed, its first impression is of the zero setting and then the accumulated cost of the petrol dispensed. A gallons wheel shaft 20 drives the counter and printer wheels through a universal coupling and bevel gears in known manner. Printer operating handle 10 moves the printing wheels into contact with a ticket through chain 58 and sprocket 60, Fig. 3. It also turns cam 76 through half a revolution to the position shown in Fig. 6 so as to rock bell-crank 90 free of lever 92. Reset shaft 22 can then be operated to set the computer to zero. In this position the pump can be operated freely without using the printer. If, however, the printer is to be used, a ticket is inserted, the handle 10 is rotated, whereby zero is printed and the cam 76 turned to the position shown in Fig. 5, in which reset shaft is rendered inoperative. After the petrol has been delivered the handle 10 is again turned to print the cost on the ticket, zeroize the printer wheels, and rock bell-crank 90 to permit resetting of the computer. To prevent the attendant printing a ticket for less petrol than is delivered, an interlock, in the form of a finger 110 and locking cam 112, prevents operation of handle 10 until the pump has been shut off by lever 12 and shaft 24 moves to the right to withdraw the finger.

A gauging device has two probes 138, 140 extending through the slot 164 of a housing 10, the probes being supported on an elevator member 50 which is pivoted to a linkage system at 70. The probes are relatively movable by rotation of a screw shaft 196, operated by a handle 202. The elevator member 50 is balanced by spring-loaded shafts 42, 44 mounted by ball bearings, one shaft 42 being longer than the other to provide vertical and horizontal stability of the elevator member. Probe 138 is mounted on a block 158 supported by reed springs 166, 168 to provide a frictionless movement. Probe 140 is mounted on a block 162 slotted to receive rods 184, 186 extending longitudinally on either side of shaft 196. A sleeve 220 mounted on shaft 216 includes a flange 214 which engages block 162 to deform openings 190, 192 to clamp rods 184, 186 against the block. A dial indicator 236 is mounted with its plunger 244 engaging block 158 and probe 138, and the end of the plunger engaging rod 226 which is connected with block 176, rods 184, 186, block 162 and probe 140. In use, the probes are positioned by the reference blocks, and slightly biased towards each other by springs 166, 180, 182 to achieve a zero setting on the indicator 236. A workpiece is then placed over the probes, causing movement of one of the probes relative to the other, thus moving the plunger 244 of the dial indicator.

In a signal storing system of the kind in which the storing is effected at a different frequency from the reading, storing is interrupted during the times of occurrence of output signals picked off from the signal store. In a cathode-ray tube system the upper beam shown is used for reading and the lower beam for writing, the frequency of writing being six times that of reading . Signals to be stored are applied as negative pulses to terminal 14 and via tube 8 and condenser 7 to the control grid 6 of the writing beam. The output signal plate 10 of the C.R.T. feeds amplifier 11 and output terminal 12. An output pulse is also fed to the control grid of tube 16 which generates a negative pulse to suppress incoming positive pulses for the duration of said output pulse.

Abstract: 1,031,466. Semi-conductor controlled rectifier inverter circuits. JOSEPH LUCAS (INDUSTRIES) Ltd. Nov. 2, 1962 [Nov. 22, 1961], No. 41736/61. Heading H3T. An inverter circuit comprises two semiconductor controlled switchable rectifiers 7, 8 connected across a D.C. supply applied to terminals 2, 3 through the appropriate portions of a tapped first winding 5 of a saturable core 4, the ends of a second tapped winding 6 being connected via a pair of capacitors 9, 10-to the gate electrodes of rectifiers 7, 8 respectively and the arrangement being such that when the core is magnetized in one direction one of the rectifiers is switched on and the other switched off but when the core is saturated the conductivities of the rectifiers are reversed and the core is magnetized in the opposite direction so that an A.C. signal is produced in an output winding. In order to start the inverter the gate electrode of rectifier 7 is connected to terminal 2 through resistor 14 and capacitor 13, thus rendering rectifier 7 conducting and resulting in current flowing through a first portion of winding 5. The resultant voltages developed across the parts of windings 5, 6 keep rectifier 8 switched off until core 4 is saturated when a negative pulse is supplied through capacitor 9 to switch off rectifier 7 and similarly a positive pulse passes through capacitor 10 to switch on rectifier 8. The current now flows through rectifier 8 and a second portion of winding 5 until core 4 is magnetized in the opposite direction when the conductivities of the rectifiers are again reversed and the cycle is repeated. The output is taken from a secondary winding 15 of transformer 16, or an output winding surrounding winding 5.

Protein fibres, e.g. wool or silk are dyed in a continuous process comprising the steps of impregnating a sliver of the fibres with a solution of dye in formic acid, the formic acid constituting at least 70% by weight of the dyeing liquor, nipping the impregnated fibres to reduce the liquor:fibre ratio to 2:1 to 6:1, feeding the fibres to a conveyor allowing the fibres to remain thereon until dye uptake has occurred and washing and drying the dyed material. The dye is preferably at 40-80C., contains 70-80% formic acid and the preferred liquor:fibre ratio is between 4:1 and 4.5:1. The dye liquor is preferably applied by spraying and the washing accomplished in formic acid baths of decreasing concentrations, e.g. 15%, 5% and 1.5% and finally a water or dilute alkali bath. The dyes may be reactive, acid milling, acid levelling and 1:1-prematallised dyes; chrome blacks may be obtained by chroming at the 1.5% formic acid wash stage.
