Title: Improvements in or relating to multiplex television systems
IPC: H04N11/12
Filed: 1953-05-22
Abstract: 737,136. Television. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 22, 1953 [May 27, 1952], No. 14492/53. Drawings to Specification. Class 40 (3). In a colour television system in which brightness signals are modulated on to a main carrier and (two) colour signals are modulated on to (two) auxiliary carriers producing at least one complete overlapping side-band on each auxiliary carrier the spacing of the auxiliary carriers being an odd multiple of half the line scanning frequency, the frequency of the latter carriers k k 1 are n+- and m+-+- times the line 4 4 2 frequency where n and m are integers and k=1 or 2, depending respectively on whether a side-band of the main carrier overlaps both or one of the side-bands of the auxiliary carriers. This arrangement allows the main carrier to contain more information (e.g. such as required in " compatible " systems) than is possible if side-band overlapping does not occur but owing to the particular selection of frequency separation according to the invention cross-talk is minimized and interference is neutralized visually since such interference signals (in the side-bands of each auxiliary carrier due to each other auxiliary carrier) are of opposite phase in successive frames assuming each frame comprises an odd number of lines. Conventional frequency changer and filter circuits are employed in carrying out the invention.

Title: Motor-driven drill hammer
IPC: B25D17/00
Filed: 1976-04-12
Abstract: 1522745 Drill hammer ROBERT BOSCH GmbH 12 April 1976 [15 April 1975] 14887/76 Heading B4C [Also in Division B3] A motor driven drill hammer comprises a percussion mechanism 4 which receives reciprocating motion from a crank pin 27 of a crank disc 22 through a cushion of air to transmit hammer blows to a tool, and a gear train comprising gear wheels which transmit rotary motion to the mechanism 4 wherein the axes of the shafts 21, 24, 25, 26 of the gear trains are mutually parallel, the axis of the motor shaft 9, 21 and the reciprocating axis of the mechanism 4 lie in a central plane of the hammer and the axis of rotation of the disc 22 is located outside this central plane. The axes of the shafts are also perpendicular to the reciprocating axis of the mechanism 4. The motor pinion 21 meshes with teeth 22<SP>1</SP> of the crank disc 22 the teeth of which also mesh in turn, with teeth 25<SP>1</SP> of a two-step gear wheel. Teeth 2511 of this wheel mesh with teeth 26<SP>1</SP> of the gear wheel 26. The wheel 26 transmits rotary motion, via coupling and bevel members 43, 55 to a sleeve member 57 of the percussion mechanism 4. A cup-like member 35 receives a dolly 34, to which hammer blows are transmitted by an intermediate member 33, and is itself engaged within a slidable sleeve 61. The sleeve 61 and the sleeve member 57 have cooperating interengageable dogs 59, 60 which interengage when the sleeve 61 is moved towards the sleeve member 57 whereby rotary motion of the sleeve member 57 is transmitted via the sleeve 61 and cup-like member 35 to the percussion mechanism 4. The coupling 43 is a safety coupling and has driven and driving sleeves 46 and 44. The sleeve 46 has radially extending bores 48 through which balls 49 are urged to engage in associated recesses 51 in the sleeve 44. If the tool seizes in the material to be drilled the balls are forced inwards against the resistance of a spring cup 50 whereby the coupling 43 overrides and stops transmitting rotary motion.

Abstract: 1381183 Making structural metal panels; joining by rolling; welding by pressure; working at specified temperatures IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd 6 March 1973 [30 March 1972] 15017/72 Headings B3A B3M B3R and B3V [Also in Division E1] A method of making a structural metal panel comprises providing an assembly of a first sheet 11 and a plurality of individual narrow second sheets 13 of metal, the second sheets having the property of superplasticity, disposing the second sheets on the first sheet after coating stripes 12 of stop-weld material upon either the first sheet or the second sheets, bonding the sheets together at the uncoated regions, applying fluid pressure between the sheets at the coated regions to expand the second sheets superplastically away from the first sheet to form hollow reinforcing sections 16. The first sheet 11 and the second sheets 13 are of titanium alloy and the sheets 13 are located with their centres over the stop-weld stripes 12. A similar assembly 11a, 13a is placed on the assembly 11, 13 with the formed sheets 13 nesting between the formed sheets 13a. The edges 15, 15a are welded together, e.g. by electron beam welding. The assemblies are passed between rolls to bond the second sheets to the first sheets, a separating layer 14 preventing bonding together of the assemblies. The assemblies are separated by shearing off the edges 15, 15a, and each is then placed in a die having a complementary shape to that of the finished panel. The die is heated to 950 C. and gas, e.g. argon, is injected along the path of each stripe 12. The sheets of each assembly may alternatively be bonded together statically between the platens of a press. The panels may be used in the construction of highspeed aircraft.

Title: Improvements in voltage and current regulated power supplies
IPC: G05F1/38
Filed: 1960-04-29
Abstract: 884,485. Automatic voltage and current control systems. STANDARD TELEPHONES & CABLES Ltd. April 29, 1960 [April 30, 1959], No. 15204/60. Class 38 (4). The voltage-sensitive bridge circuit 10 of a voltage and current regulated power supply includes a zener diode Zn for providing a substantially constant reference voltage on one arm of the bridge. The collector current, preferably amplified, of a transistor Tr1, passes through a control winding L1 of means supplying a D.C. voltage Ei. An arm R5 of a currentregulator bridge 11 carries the output line current Io and a transistor Tr2 is biased beyond cut-off when the Io is less than overload current a-b, Fig. 4. If input voltage Ei tends to fall from the pre-set value Eo, point 4 becomes. negative with respect to point 3 and the voltage Ei is increased as a result of the increased collector current of Tr1. Means L1 controls the voltage Ei and may comprise the control winding of a saturable reactor or the field winding of a motor driving tapping means on a transformer or potentiometer. The bridge 10 also compensates for the drop across R5 with increasing current. After point b, Fig. 4, the increased drop across R5 causes Tr2 to begin to draw current through R1, R2 of bridge 10, and the collector current through L1 is reduced or cutoff and voltage Ei is reduced. The voltage EO is now controlled by Io until, at point c, Fig. 4, Tr2 is driven to full collector current and R6 is shorted out. Tr2 has substantially no effect if the current Io is increased above the value Io1 and thereafter the voltage bridge 10 holds the output voltage at the new lower value Eo2. The slope of the portion bc may be varied bc1, bc2 by altering R7 and consequently R5. The temperature gradient of the controlled voltage Eo may be varied by selection of components with suitable temperature characteristics for Zn, R5 or R6. For the control of the temperature gradient of the current Io, part or all of R1 or R2 may be temperature dependent.

Filed: 1926-06-17
Abstract: 253,929. Kraus, C. E. June 18, 1925, [Convention date]. Compositions containing aluminous and alkaline eaths.-Olay, kaolin, bentonite, and the like, to which may be added diaspone, bauxite, or like materials to produce a composition containing 12 per cent or upwards of alumina, is heated to a temperature insufficient to drive off all the water of crystallization, mixed with materials containing alkaline earths such as limestones, calcium oxide or hydroxide, gypsum, Portland cement, marl, made into a slurry, and digested with sulphuric acid. For some purposes the slurry may be roasted without additional alkaline earth, but usually further alkaline earth is added, producing further reaction, and the product is burnt with or without the addition of more alkaline earth, to make a cement. With a bigh percentage of sulphates, a temperature of 250-450 F. gives a quick-setting product; where a high percentage of calcium hydroxide is present, a temperature of 400-600 F. is preferred. The reaction is accelerated by adding alkali to the aluminous earth before heating. Numerous examples are given in the Specification. Specification 18145/92 is referred to.
