Filed: 1973-03-13
Abstract: 1374203 Ultrasonic testing DEFENCE SECRETARY OF STATE FOR 13 March 1973 [12 April 1972] 16811/72 Heading H4D [Also in Division G1] Testing apparatus includes a detector receiving radiation transmitted through a specimen, an analogue device providing signals to be expected from a perfect specimen, means for providing relative movement between the specimen and detector, means for selecting a signal from the analogue device corresponding to the position of the detector and means for indicating any difference between the signal and the detector output. The analogue device 10 comprises a phenolic resin base 11a covered with a conductive layer 11b (graphite). A matrix of pins 17 projects through the base and contacts the layer. The pins are connected to an edge connector 18. A source of voltage 20 and chain of resistors 21 provides n voltage values at edge connector 22. The two connectors 18, 22 are interconnected by a board 19, wired according to the object under test. When in place, the potential distribution over the layer 11b represents the signal which should be received at detector 3 from transmitter 2 after passage through specimen 1. The transducers are moved by servomotors 4-7, which also move probe 12 via followers 13-16. The probe and detector outputs are compared by comparator 9. Ultrasonic or light pulses may be used with suitable transmitters and detectors, and stated uses are checking extrusions, the filling of solid fuel rocket motors or the correct printing of a pattern.

Abstract: 457,502. Plug couplings. BONSON, E. W., 3, Fox Court, Holborn, London. June 15, 1935, No. 17288. [Class 38 (i)] A socket member b carrying contact sockets d attached to supply leads through fuses g has means for securing the fuses to the socket-carrying part of the divided body of the member b so that when the part k is removed to give access to the fuses, the latter are not live. For this purpose the fuses pass through slots in a plate a that fit the body of the fuses but prevent the caps h from passing. The plate a is secured by a screw and is detached when it is desired to remove the fuses. Alternatively slots n, Fig. 9, for the fuses may be connected to a central enlargement o so that by pulling each fuse out of its clip e and moving it to the centre it can be removed without detaching the plate a. The lower fuse clips e are made in one with the sockets d and mounted on the plate a.

Title: Process for bleaching textile goods and fibrous substances of all kinds with hydrogen peroxide
IPC: D06L4/70
Filed: 1930-06-05
Abstract: A process for bleaching textile articles, &c. with hydrogen peroxide consists in impregnating the material with a solution of low concentration, preferably within the limits of concentration 0,05 to 5 parts by weight per 100 parts of solution, rendered alkaline for example with water-glass, pyro-phosphate, soda lye or ammonia, preferably within the limits of concentration of 0,5 to 5 parts per 100 parts of water, the material being then maintained at the requisite temperature to complete the bleaching while preventing evaporation and radiation and without substantial addition of liquor. This latter may be effected by tightly packing the impregnated article in a container and surrounding it externally with bleaching fluid; or it may be soaked in a cold or warm solution of the bleaching fluid and then tightly rolled up in an atmosphere of steam. To avoid undue catalytic action upon the hydrogen peroxide the article is preferably subject to a precleaning treatment.  In an example raw cotton was pretreated by impregnating it with a 0,2 per cent solution of hydrogen peroxide at 80 DEG  C., made alkaline with water-glass and caustic soda.  It was then tightly packed into a container and bleached for 4 hours.  After washing it was treated by a 0,3 per cent solution of hydrogen peroxide at 80 DEG  C., made alkaline with water-glass only, and tightly packed for 2-3 hours.  It was finally squeezed and washed.  The second bath may be subsequently used for a pretreating bath.

Abstract: 896,235. Packaging machines. PAPER SACKS Ltd. May 13, 1960 [May 22, 1959], No. 17459/59. Class 94(1). A device for placing groups of articles into bags or cartons comprises a rotatable platform on which the articles are assembled, the platform then being turned through 90 degrees and the group thrust into the container supported on a filling guide. The platform has four compartments defined by members 8 and is rotatable on a shaft 7. Articles are assembled against the members 8 and a fixed end guide 10 and the platform is indexed 90 degrees by an air motor 16 and linkage 21. The operation of the motor simultaneously swings back an alignment plate 11 on a rod 12 pivoted at 13 and causes the upper portion 5a of the filling guide to approach the lower portion 5b. A container is placed over the guide and the motor 16 again operates to open the guide and advance the plate 11 to level up the group of articles. A plunger 3 then forces the group into the container. During the filling operation a new group may be assembled in the next compartment.

Abstract: 238,502. Wiegand, E. L. March 11, 1924. Wire and ribbon resistances, embedded and encased.-A process of mal:ing a heating element of relatively thin cross-section and relatively large surface area consists in introducing into a receptacle a refractory-insulated resistance and closing the receptacle. The resistance 37 is introduced into a sheet-metal receptacle 35 containing refractory material 36 after which further refractory material is added and the partially formed element is then subjected to compression and dried. A cover plate 38 is then applied and the edges of the receptacle, are bent over to hold it in place. The cover plate may be perforated and may be applied before or after compression, after which the element may be bent to the required shape and subjected to further compression so that the perforations become filled with the refractory material, the element being then dried and baked by external heat or by energizing the resistance. Other forms of heating elements which may be formed by the process are described in Specification 221,180. The refractory material may consist of magnesium silicate, zirconium silicate, or aluminium oxide, or a mixture thereof, and a binding material such as clay. The resistance is preferably inserted in the receptacle by means described in Specification 221,894, [Class 87 (ii), Moulding plastic &c. substances]. Reference has been directed by the Comptroller to Specifications 14176/03, 140,738 and 181,940.

Thermionic generators. - A piezoelectric oscillator employing a screened-grid valve or valves, produces oscillations inde - pendent of the frequencies fixed by the inherent capacity effects existing between the valve electrodes. The piezo-electrode crystal 1, Figs. 1, 2 is connected between the control grid 18 and the filament 17, of valve 5, grid bias being supplied from a source 3, through a radio - frequency choke 2. Coupling between grid and plate circuits is by means of variable condenser 12, and the screen-grid 16 is positively biassed from a tapping 15 on the anode supply 6 which may be in series, Fig. 1, or in parallel, Fig. 2, with an oscillatory circuit comprising inductance 7, variable capacity 8 and ammeter 9. In the latter case a radio-frequency choke 13 is connected between the anode 19 and the anode supply 6, the latter in each case being shunted by a condenser 10, while a condenser 11 shunts the screen-grid supply. An inductive coupling through coil 14, Fig. 3, may be provided which opposes and limits the capacitative coupling produced by the condenser 12. A push-pull arrangement, Fig. 4, may be used in which the crystal 1 is connected between the valve grids 18, 18<1> of the two valves 4, 4<1>, a common grid battery 3 biasses both grids through radio-frequency chokes 2, 2<1>, a common anode supply 6 feeds both anodes 19, 19<1> through a common oscillatory circuit 7, 8, and tappings 15, 15' on the anode supply 6, bias the two screen grids 16, 16'.
