Title: Method of producing decorated glass-ceramic articles
IPC: C03C10/12
Filed: 1972-08-03
Abstract: 1368181 Coloured glass-ceramics CORNING GLASS WORKS 3 Aug 1972 [12 Aug 1971] 36239/72 Heading C1M Coloured glass-ceramic articles are produced by applying to an alkali metal-containing glass crystallizable at or above 1085‹ C. a composition consisting of (by weight) 5-15% of at least one silver compound, 5-15% elemental sulphur, and either (a) 45-90% of at least one transition metal compound, or (b) 40-80% of at least one transition metal compound and 5-10% of at least one binder, and heating to at least 1085‹ C. for sufficient time to crystallize and colorize the glass. The transition metal compound is a compound (preferably an oxide, chloride or sulphate) of Fe, Mn, Ni, V, Cr, Ti or Co (e.g. Fe2O3, Fe3O4, NiO, NiCl2, MnSo4, Cr2O3, TiO2 or Co3O4). Preferably the binder is bentonite, but it may be organic. The composition may be applied as a powder, or as an aqueous or alcohol slurry or paste by spraying or silk screening. Heating at 1100-1150‹ C. for at least 2 hours produces adequate coloration, e.g. to a depth of 50-200 Á. Alkali-metal ions in the crystallizable glass are thought to be exchanged for silver and transition metal ions, with a subsequent reduction of silver ions to silver. The crystallizable glass preferably contains Li ions, and crystallizes to form a #-spodumene phase. Examples of suitable compositions are given. After heating the colouring composition residue may be removed by washing, and the glass-ceramic polished mechanically.

Title: Improvements in or relating to windscreen wiper blades
IPC: B60S1/38
Filed: 1953-12-30
Abstract: 801,983. Windscreen cleaners. O'SHEI, W. E. Dec. 30, 1954 [Dec. 30, 1953], No. 36252/53. Addition to 748,759. Class 138(1). A modification of the windscreen wiper blade claimed in the parent Specification consists in the backing member, which extends towards the outer end of the blade, being made flexible at least partway along its length towards its outer end. In the embodiment shown in Fig. 1, channel-shaped metal backing members 1 and 7 are provided at the free edges of their side walls with inturned flanges which engage in wide grooves 3 in the sides of the squeegee element 4 so that the rear portion of the latter can move into and out of the backing members as it conforms to a curved windscreen in the manner described in the parent Specification. The backing member 1 which is most remote from an actuating shaft for the blade has a portion of its rigid channel removed adjacent its outer end so as to leave only two metal flanges 2 constituting flexible strips engaging in the grooves 3. A yoke member 5 is connected at its ends to the free ends of the strips and to the opposite end of the member 1, one or both of the connections permitting relative longitudinal movement between the yoke and the backing member. A bridge-piece 6 interconnects the yoke 5 and the backing member 7, the bridge-piece being connectible to a wiper arm. If desired both backing members may be formed part rigid channel section and part flexible strips and in this case each backing member will be provided with a yoke, the yokes being connected to the ends of a bridgepiece. In another form only one backing member is employed being formed for part of its length as a channel and for the remaining part as strips. The yoke and bridge-piece in this case are arranged in the manner shown in Fig. 1. In a further modification a channel-shaped backing member may be made flexible part-way along its length by notching its side walls, the parts of the walls between the notches forming fingers provided with inwardly extending flanges.

Abstract: 1,241,828. Electrode materials. RADIOTEKHNICHESKY INSTITUTE AKADEMII NAUK USSR. 1 Aug., 1968 [23 Aug., 1967], No. 36731/68. Addition to 1,061,061. Heading H1D. An electronic vacuum tube device for either continuous or pulsed operation includes an electrode provided with a protective coating against erosion effects and gas emission caused by electron bombardment and, between the electrode and protective coating an intermediate layer or region to ensure reliable adhesion and good thermal contact therebetween which has specified thermophysical properties which are essentially intermediate those of the electrode and the protective coating. The protective coating consists of at least one refractory material having a permissible heating temperature in vacuum above the melting point of copper, and the thickness thereof must be such that its thermal resistance to a thermal flow is as small as possible in comparison with the thermal resistance of a similar electrode without a coating or intermediate layer or region and does not exceed it, but is simultaneously sufficient to conduct away the mean thermal power at pulsed or continuous thermal loads exceeding by at least twice the maximum load which would be permissible for a similar electrode without a protective coating and intermediate layer or region. The electrode may be of copper and the protective coating material may comprise one or more of the metals Mo, Re, Nb, Ta or W, or carbides, borides, nitrides or silicides thereof. The material of the intermediate layer or region may comprise Fe, Au, Ni, Ti, Pt or Rh or the carbide of Mo or W. The intermediate layer or region may be a distinct layer of material different from either that of the protective coating or the electrode, or may be a partially diffuse layer, e.g. in which Pt is diffused into the copper electrode as well as the tungsten protective coating, such that there is a gradual and continuous change in the thermophysical properties between the electrode and the protective coating. Alternatively, the intermediate layer or region may be a diffuse region formed by the forced diffusion of ions of the protective coating material into the electrode material, e.g. by the galvanic application of tungsten or rhenium on to copper, or by driving tungsten ions into copper in a vacuum. Preferably, the thickness of the protective coating may be between 1 and 10 microns when the tube is operated continuously and between 5 and 200 microns when the tube is pulsed. The electrodes are preferably cooled, e.g. by air, oil, alcohol mixes or boiling or running water.

In the electric motor control system, as shown, the power circuits are in heavy lines, and the control circuits in light lines, subsidiary numerals 1, 2 and 3 respectively denoting features associated with the main disc-driving motors 23, 24 and the motor 133. AH is a manual switch for changing from manual to completely automatic control, and HH a manual starting and stopping switch., On starting, rise of a float 120 in the pulp supply system causes starting contactors S1, S2 of motors 23, 24 to close, and subsequently running contactors N1, N2 are closed, and, through a time-relay MQ &c. contactors of the motor 133 which moves one disc towards the other, during the latter part of which movement, a valve 47 is turned to direct pulp into the machine, and thus close by pulp pressure, a switch 124, the time relay MQ opening an interlock IQ. The motor 133 is stopped by stalling under working pressure, whereupon a relay T3 opens the circuit of the motor 133, or failing this, or as an alternative, at a predetermined disc clearance, the motor is stopped by opening a contact LS3F by a cam 145 turned through reduction gearing by the motor 133. The stalling torque is controlled by using the required tapping of an auto-transformer AT. If the switch 121 is opened by the float 120 falling, contactors N1, N2 open, the reverse circuit for the pilot motor 133 is completed, and during the first part of the disc separating movement the valve 47 rotates into the position shown, byepassing the pulp supply from the refiner, and opening the switch 124, the disc separation continuing until the motor 133 is stopped by the cam 145, or failing which, it stalls against pressure of a spring, whereupon a thermal overload relay OL3 opens the pilot motor circuit. If the switch 121 fails to operate when the pulp supply fails, the pressure switch 124 opens to produce the same results. Stoppage of either main motor 23, 24 by its thermal overload relay OL1, OL2 also starts the pilot motor to separate the discs &c.

Title: Improvements relating to the sorting of signals recorded on a magnetisable signal carrier
IPC: G06F7/24
Filed: 1950-06-23
Abstract: 786,030. Sorting digital data. DIRKS, G. June 23, 1950 [Oct. 1, 1948], No. 37211/54. Divided out of 786,021. Class 106 (1). Information items, each consisting of a group of signals, recorded on a first magnetizable track, are sorted by transferring each group selectively, in accordance with the value of a signal within the group, to one of a plurality of magnetic recording means co-operating with a like plurality of secondary magnetic tracks. Alternatively, each item from the first track may be recorded on all the secondary tracks simultaneously, all but the appropriate recording being erased immediately afterwards. In a first embodiment eleven tapes are fed between two sets of reels (Fig. 1, not shown), by step-by-step feeding means of the type described in Specification 786,031. The information to be sorted is recorded on a first tape in successive areas or " unities " each equivalent to an eighty-column record card, one " unity " being dealt with at each step. The value of a digit in a control column of the unity selected by an adjustable inductive selector determines to which of the ten secondary tapes the whole information contained in that unity shall be transferred. The selected secondary tape is fed forward by one step during this operation. When all subsequent unities on the first tape have been dealt with similarly, the contents of each secondary tape are re-recorded on the first tape in their proper order and a second sorting phase takes place under control of another control column of each unity in a manner analogous to the sorting of record caids. As shown in Fig. 9, during movement of the first tape 9<SP>10</SP> relative to sensing heads 3<SP>0</SP> ... 3<SP>e</SP> the information contained in one unity is transferred to all the ten sorting tapes 9<SP>0</SP>, 9<SP>1</SP>, 9<SP>2</SP> ... &c. as they move relatively to the sets of recording heads 22<SP>0-e</SP>, 23<SP>0-e</SP> ... &c. By the end of this movement the control digit will have been selected under the control of an inductive selector 14, moving in synchronism with the tape movement, and that one of the tubes 34<SP>0</SP> ... 34<SP>9</SP> will be ignited which corresponds to the value of the control digit. This tube suppresses a high-frequency erasing signal at the heads of the selected tape; the erasing signal is, however, applied to all the other recording heads during their return movement; moreover, the selected tape is fed forward during this action. In a modification (Fig. 10, not shown), a cathode-ray tube distributer of the type described in Specification 786,051 is employed. In another embodiment the sorting control digit is sensed first and recorded on an electronic tube or on the tape itself for use in the next sorting stage. Specification 786,034 also is referred to.
