Abstract: 597,336. Doors, windows, etc.; excluding draughts and preventing rattling. BROWN, T. May 3, 1945, No. 11214. [Class 20(iii)] A draught or weather excluding device for doors, windows, and the like comprises a resilient metallic strip anchored at one end and extending across the gap to be sealed, the strip having a thickness of from two to four thousanths of an inch. The strip may be of brass, copper, phosphor bronze, steel or tin plate. As shown in Fig. 1, the strip has plane surfaces 4, 5, but a curved or corrugated section may be provided. The attachment is by nails, or by drawing-pins 6 which may be attached to the strip by welding, soldering or the like. Alternatively, wood - penetrating tongues may be struck up from the strip. The strip may be welded or soldered to the outsides of the heads of the pins 6 or may be bent on itself to lie both over and under the heads of the pins 6, and the' outwardly directed part 5 of the strip may be omitted. The strip may be attached to a wooden member 12 secured, as shown in Fig. 5, to the bottom of a door 13, and in the case of worn floors or steps, the strip may be cut transversely to provide a number of independent excluders having varying degrees of accommodation to the irregular floor. In a modification, Fig. 10, the strip engages a V-groove 14 in the opening edge of a door 16 to serve as a catch and antirattle means. The edge of the strip may be extended at 18 to engage the face of the door to cushion the door against slamming. A V-section strip may be inserted with its apex directed parallel to the floor between the skirting and floor boards, and secured by a few widely spaced nails passing at right angles through the apex into the floor.

Title: Improvements in or relating to opening and closing arrangements for vehicle doors
IPC: E05F15/02
Filed: 1956-04-12
Abstract: 805,796. Door operating devices. HAGGLUND & SONER A. B. April 12, 1956 [April 12, 1955], No. 11231/56. Class 65(1) [Also in Grop XL(b)] The opening of the exit door of a driver operated bus is dependent upon the application of the vehicle brakes and closure occurs after a predetermined time interval unless delayed by sensing means influenced by the presence of a passenger near the doorway. A passenger wishing to alight operates one of the push buttons 3, energizing coil 5 having hold on contacts 7, and illuminating the signal plate 1 and control lamp 2. After application of the vehicle brakes the driver can operate push button 24 to energize coil 26 to effect closure of contacts 29, 28 to energize coil 31 to lock the brakes. Simultaneously the coil 10, in series with photo-electric cell 9, is energized to close contacts 11, 12 to energize coil 21 to effect opening of the door. The door, when fully open, opens contact 4, causing contacts 7 to open and contacts 6 to close, lighting the lamp 8 which illuminates the photo-cell 9. The consequently increased resistance of the cell causes contacts 12, 11 to open, and after a period predetermined by the setting of the throttle screw 19 in the damping device 14, the contacts 12, 13 close to energize the door closing solenoid 22. If during this period the beam of light from lamp 8 is interrupted by a passenger the contacts 12, 11 are again closed and the door opening solenoid is again energized. The brakes can be released by pushing the throttle pedal to close contact 25 to energize the brake release coil 32. The photocell device may be replaced by movable plates with mechanical contact means or the cell may be completed with an electronic relay circuit so as to obtain a sufficient feed for the coil 10.

Abstract: 1,140,173. Code translators. INTERNATIONAL STANDARD ELECTRIC CORP. 10 March, 1967 [15 March, 1966], No. 11303/67. Heading G4H. A translator for binary coded signals includes means to detect the binary condition of the most significant digit of the signal and means to complement the remaining digits of the signal if the most significant digit is a binary "1". In the embodiment described if the most significant digit fed from a source 22 is a "1" it is fed via AND gate 4 during a first time interval t1 to set a bi-stable device 2 to its "1" state, the bi-stable device priming a further AND gate 5. During a second time interval t2 when the second digit of the code is supplied to the apparatus a bistable device 3 is set to its "1" state so that AND gate 6 is disenabled and AND gate 7 is primed and the remaining digits are fed through an inverter 9 and the AND gate 7 to an OR gate 8. If however the first digit is a "0", AND gate 4 is disabled and an AND gate 6 is primed by the zero output from bi-stable device 3 to feed the signal from the source 22 to the OR gate 8.

Title: Steroids
IPC: C07J1/00
Filed: 1967-03-10
Abstract: 1,180,584. Steroids. TAKEDA YAKUHIN KOGYO K.K. 10 March, 1967 [11 March, 1966; 12 March, 1966 (2); 29 April, 1966; 31 May, 1966; 15 Oct., 1966 (5)], No. 11383/67. Heading C2U. The invention comprises a compound having a gonapenta-, tetra- or tri-en-17α-ol nucleus, the nucleus being substituted with a hydrocarbon residue in the 13-position and a process for producing a compound having a 13-substitutedgona-1,3,5(10), 8, 14-pentaen-17α-ol nucleus which comprises: (1) reacting a compound having a 13-substituted 8,14-secogona-1,3,5(10),9- tetraene - 14,17 - dione nucleus with a " metallic complex " to produce a compound having a 13 - substituted - 17α - hydroxy - 8,14 - secogona- 1,3,5(10),9 - tetraene - 14 - one nucleus, the 13- substituent being a hydrocarbon residue; and (2) subjecting the product of step (1) to dehydration in the presence of an acid catalyst. As metallic complex in step (1) there may be used alkali metal boron hydrides, alkali metal aluminium hydrides and aluminium isopropoxide. The 17-hydroxy compounds thus obtained form a racemic mixture which may be resolved to obtain a (+) or (-) 13-substituted-17α- hydroxy - 8,14 - secogona - 1,3,5(10),9 - tetraene- 14-one compound which may be subjected to intramolecular cyclization e.g. in the presence of an acid catalyst to give compounds having a (-) 13-substituted-17α-hydroxy-gona-1,3,5(10), 8,14 pentaen-17-one nucleus which may be catalytically reduced e.g. with Raney nickel to the corresponding 13-substituted gona-1,3,5(10), 8 - tetraen - 17α - ols in which the hydrogen at 14-position is α-orientated. Further reduction of these compounds with an alkali metal in liquid ammonia at position 8 gives the corresponding 13 - substituted gona - 1,3,5(10)- trien-17α-ols which may be reduced in the aromatic ring to produce a 13-substituted-gona- 2,5(10) - dien - 17α - ol. Each of the last two products may be oxidized by e.g. Oppenhauer, to the 17-one compounds. These reactions are applicable to racemic mixtures or optical isomers.

IPC: G01G23/18
Filed: 1965-03-18
Abstract: 1,088,887. Measuring speed electrically. MERRICK SCALE MFG. CO. March 18, 1965, No. 11527/65. Heading G1N. Relates to the measurement of the speed of a shaft (which may be connected to a weigh belt conveyer) on which is fixed a wheel having a number of conductive teeth which are arranged to pass in proximity to windings 18, 19 (Fig. 3) of a pick-up coil 12. As a tooth approaches the coil, the "Q" thereof is lowered and a transistor 9, 10, 11 of a Hartley oscillator, including the pick-up coil, is blocked whereby oscillation ceases. Oscillations (e.g. at 400 Kcs) are restored as the tooth moves away from the coil. The transistor 9, 10, 11 output is fed to a detector 33 the output of which is a series of square waveform negative voltage pulses each occurring during the period when oscillations exist. The duration of the pulses is determined by the teeth spacing and the speed of the shaft. The detector output is applied to the base electrode of a transistor amplifier 32 which conducts and energizes a relay coil 40, when its base electrode receives a negative pulse and thereby the relay armature 43 is moved away from a contact 41 to a contact 42. The relay contacts 41, 42 are connected respectively to the primary windings 44, 46 of a saturable transformer, and as the relay armature changes over, current flows through each winding section in turn sufficient to saturate the transformer core in opposite directions alternately. The transformer secondary current is full wave rectified and the average D. C. value of the pulses is proportional to the repetition rate of the armature and hence of the shaft speed; and may be fed to an indicator or recorder. The speed representative signal may be combined with a signal from a weigher Fig. 2 (not shown) to indicate the load carried by a conveyer per unit time. An alarm may be provided to indicate overload.

Abstract: 838,713. Flexible laminates. DORNBUSCH, P., [trading as DORNBUSCH & CO.]. April 10, 1957 [April 23, 1956], No. 11732/57. Class 140. [Also in Group XVI] A composite web comprising a fabric, paper, or other fibrous backing carrying a polyvinyl chloride or other plastics layer of open lattice or like construction, for example as in Fig. 1a is made by pressing the plastics material into the recesses of an engraved roller, maintaining the contacting surface of the material at softening temperature, as by heating the roller, heating the exposed surface of the material, for example by radiant heat, to fusion temperature, and applying the backing to it by means which press the backing into the recesses of the roller. As shown in Fig. 1 plastics material extruded from a nozzle 4 is applied by a roller 3 to a roller 1 engraved with a lattice pattern, surplus material being removed by rollers 5, 5<SP>1</SP>. Rollers 1, 3 are heated to soften the material and maintain its surface in contact with roller 1 at softening temperature; its outer surface is heated to fusion temperature by infra-red heaters 6 on a pivoted and adjustable arm 16. A web 8, of fabric, paper or like backing material is fed from a roll 7 by a roller 9 between the roller 1 and a roller 10 which presses the backing against the lattice web formed by the roller 1 at all points of the lattice. The composite web then passes through an oven 12. The roller 10 may have a hard facing 10i of parchment paper embossed with a relief pattern which is complementary to but shallower than, for example, half the depth of, that in roller 1 so that the web 8 is pressed partly into the recesses in the latter. Alternatively the roller 10 may be faced with synthetic rubber sufficiently resilient to enter the recesses at the pressure point. The roller 9 may apply a polyester or other adhesive to the web 8 to assist bonding of the webs. A roller may be provided above roller 10 to flatten and if desired apply a finish to the lattice web, and, when the lattice produced is a close one, an additional roller may apply a silicone composition to prevent the meshes from closing entirely during flattening.

Abstract: 222,792. Woosnam, A., (Hulse Manufacturing Co.). June 1, 1923. Embossing. - An embossing-press, more particularly for use in forming embossed advertising, display, &c. cards by punching characters from coloured paper and forcing them into a cardboard backing, comprises a fixed platen and a cam-operated bed movable towards and away from the platen, means being provided for adjusting the cam and bed bodily toward or away from the platen so that the desired depth of penetration of the type into the cardboard can be obtained. The body portion of the press consists of a metal casing of rectangular form attached at its bottom wall 5 to a pedestal 1 by bolts 9 entering key-hole slots in the casting. Between the side walls 11, 12 of the casting is mounted the movable bed 14 which is pressed downwardly by springs 17 and between which and the operating cam 18 are situated a set of anti-friction rollers 38 and a horizontally movable thrust-plate 36. The ends of the rollers 38 are held in retainers 47 which, together with the plate 36, are pressed in a direction opposite to that in which the cam tends to move them by a spring 53. A similar arrangement of a thrust-plate 37 and anti-friction rollers 46 separates the cam from two adjustable wedges 39, forced apart by a spring 42 and sliding on inclined grooves on the bottom wall 5 of the main casing, the wedges serving to lift the cam and bed bodily toward the fixed platen 10 constituted by the top wall of the casting. The cam 18 is formed with two parallel flat faces 19, 20 joined by two arcuate faces 27, 28 one of which is eccentric to and the other of which is concentric with the axis of the cam shaft, so that the bed is quickly lifted into engagement with the platen by the first part of the stroke of the cam and large leverage is obtained during the latter part of the stroke to force the type into the cardboard. Vertical movement of the cam is allowed by forming cylindrical parts 21, 22 near the ends thereof, which engage with vertical slots in the main casting. An operating handle 25 is attached to the end of the cam shaft and is provided with a stop 31 engaging a groove 34 in the side of the main casting so that the cam is given only the necessary amount of oscillation. The cardboard, embossing-type, and coloured paper are held on a carriage preferably constructed as described in Specification 222,539.
