Title: Improvements in and relating to electric junction units for bus-bar duct systems
IPC: H02G5/06
Filed: 1950-02-10
Abstract: 680,830. Two-part couplings. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Feb. 10, 1950, No. 3481/50. Class 38 (i). A sectionalising feedunit for a bus-bar duct system comprises a tubular metal duct-section 14 on which is mounted a metal box 19 housing terminal blocks 23, 24, the terminals of which are connected to the busbars in the right- and lefthand sides of the duct respectively, an insulating plate being interposed between the two sets of bus-bars. In the case of a centre feed-unit, a single terminal block is mounted in the box and connected to bus-bars extending continuously through the duct-section. The feed-unit shown in Fig. 5 is for use at the end of a duct. A duct-section 38 carrying bus-bars 40 is brazed into a wall of a box 37 and the bus-bars connected to terminals 44 on a block 43 in said box. The slot at the base of the duct-section may be closed by a dust cap 46. The duct-section is connected to the main duct by double-ended jacks 42 fitting into the ends of the bus-bars which are tubular. Similar jacks are also used in the preceding embodiments. Fig. 9 shows another feed-unit for use at the end of a duct in which the terminal box 65 has a plate 66 riveted thereto, said plate having a cross-piece 67 with clamping screws 68 engaging the top of a duct section and a foot 70 with a cross-piece 71 adapted to be clamped to the base of the duct section by a screw 72. The plate is apertured for the passage of connections from the bus-bars to the box.

Title: Hand stropping machine for safety razor blades
IPC: B24D15/08
Filed: 1940-02-24
Abstract: 534,437. Stropping razor blades. ALLEN, W. G. Feb. 24, 1940, No. 3482. [Class 60] In a device for stropping safety razor blades the blade is located on a strip H having projections Q to engage the holes in the blade and is held thereon by a spring plate I with catch J. Lugs G on the strip pass through slots F in a cam plate E fitted with a handle. 'A pivot C carried by the lugs G passes through holes in lugs B carried by a curved frame A, the edges of which pass under lugs P and over lugs O on the plate E to connect the frame and plate so that the frame has a limited lateral movement due to the friction of the strop that passes under the pivot C and over the curved parts of the frame, This movement causes the lugs G to tilt the strip H and thus press the blade on to the strop.

Title: Temperature-sensitive electrical protective arrangements
IPC: H02H5/04
Filed: 1963-01-28
Abstract: 1,025,530. Protective arrangements. SIEMENS - SCHUCKERTWERKE A.G. Jan. 28, 1963 [Jan. 26, 1962; Aug. 3, 1962], No. 3519/63. Heading H2K. In a protective arrangement for electric machines &c. and employing a temperaturesensitive element 3 in a bridge circuit 3, 13, 14, 15, a relay 11 is released both if the element 13 is broken or shorted and if the temperature of the machine exceeds a predetermined value. Current normally flows through relay 11 by way of resistors 7, 10 and a diode 12 and the relay is held on. Under normal conditions, the bridge is balanced but with increasing temperature the resistance of element 3 alters, unbalancing the bridge so that a potential difference appears between points a, b which is applied by way of resistors 8, 9 and a bridge rectifier 6 to the relay 11 to oppose the standing current and eventually to release the relay. Diode 12 ensures that the current through relay 11 cannot reverse its direction. The element 3 may be of positive or negative temperature coefficient and may be in series or parallel with other resistors to alter its characteristics. The relay may be replaced by a transistor amplifier &c.

Title: Improvements in or relating to conveyors

Filed: 1939-02-02
Abstract: 524,607. Conveyers. MACDONALD, J., and G.W.B. ELECTRIC FURNACES, Ltd. Feb. 2, 1939, No. 3536. [Class 78 (i)] To charge and discharge a furnace or perform similar transporting operations, a frame 1 is hauled to-and-fro on a support by a chain 2 driven through reversing-gear from a motor 4. A wheeled lifting-frame 10 is mounted on and moves normally with the frame 1. As the latter reaches the end of its movement towards the left into the furnace 5, the frame 10 contacts with a stop and the continuing forward movement of the frame 1 then causes the wheels 11 to rise up the inclines 8 into the recesses 14, thus lifting the frame 10 and the load. On the backward run the raised frame 10 and frame 1 move together as a unit until the frame 10 is again arrested and rides down the inclines 8 again. To charge the furnace, the frame 1 initially is run backwards from the position shown in Fig. 1 so that the wheels 11 ride up the other inclines 9 and so raise the frame 10 to pick up a load at this point.

Filed: 1955-02-07
Abstract: A water-soluble carboxyl-group-containing synthetic polymer or a salt thereof is added to a system comprising an aqueous continuous phase and finely-divided heteropolar disperse phase to bring about agglomeration of the latter.  The additive may be a polymer or copolymer of acrylic, methacrylic, crotonic or maleic acid. Examples: the sedimentation and filtration rates of calcium carbonate, formed in a state of fine division by reacting sodium or potassium carbonate with slaked lime in the production of dilute lyes, are increased and reduced respectively by adding a solution of the sodium salt of a copolymer of methacrylic acid and methacrylic acid methylester; the precipitation of strontium hydroxide or carbonate from aqueous suspensions thereof is accelerated by the addition of the Na salt of a copolymer of methacrylic acid and the methyl ester thereof; the sedimentation rate of dicalcium phosphate produced by reaction of mono-calcium phosphate with slaked lime is increased by addition of a copolymer of methacrylic acid and methacrylic acid ethylglycolester in the form of its Na-NH4 salt; the sedimentation rate of lithopone pigment produced by reaction of zinc sulphate with barium sulphide is increased by adding the sodium salt of a copolymer of methacrylic acid and of methacrylic acid methylester; aqueous suspensions of fuller's earth are separated by addition of polymer salts.  Specification 725,460 is referred to.ALSO:A water-soluble carboxyl-group-containing synthetic polymer or a salt thereof is added to a system comprising an aqueous continuous phase and a finely-divided heteropolar solid disperse phase to bring about agglomeration of the latter.

Filed: 1940-02-26
Abstract: 538,389. Tuning wireless receivers. PHILIPS LAMPS, Ltd. Feb. 26, 1940, No. 3574. Convention date, Feb. 28, 1939. [Class 37] A plurality of tuning dials arranged rectilinearly are traversed by the same pointer, the control members being designed to cause the main tuning member and the pointer to move slowly over the required frequency band and the tuning,member to move more rapidly.from one frequency band to another. In the arrangement, Fig. 1, the pointer 38 is moved over three dials 47 by an endless band 39 driven by a drum 35 with a smaller drum 34 over which a cord passes from a spring 37 to a point 36 on a lever 30. This lever is pivoted at its ends to members 52, 42 adjustable by push buttons 54 and a knob 43 ; and a point 33 on the lever is connected by a cord 32 to the sliding member of a tuning condenser 31. The frequency band is selected by setting the left end of the lever 30 to one of the points 40, 50, 60 by the appropriate push button 54. This moves the tuning condenser 31 rapidly to the desired band. Tuning within the selected band is then performed slowly by the knob 43. In another arrangement, Fig. 2 (not shown), a single operating knob operates a rack carrying the pointer and three transverse rods of different lengths co-operating in succession with a cam on the movable electrode of the tuning condenser. The Specification as open to inspection under Sect. 91 comprises also : (1) arrangements for tuning the input and output circuits of a mixing valve, each circuit having three condensers selected by a switch, and a variable condenser or a variable inductance ; (2) arrangements of aligned and superimposed rectilinear dials illuminated by separate lamps according to the frequency .band selected ; (3) an arrangement in which a tuning circuit includes five adjustable condensers selected by a switch in parallel with a combination of a main variable tuning condenser in series with fixed condensers selected by a switch, the two switches being coupled together and operated automatically when a pointer connected to the main tuning condenser passes from one dial to another of a set of rectilinearly disposed dials, the pointer co-operating with five contact strips connected to a relay through a five-point switch to operate a motor one switching step at a time ; and (4) various minor modifications of the arrangements described above.
