Title: Instrument for recording weights and modifications in weight
IPC: G01G7/04
Filed: 1952-10-28
Abstract: 727,171. Electric weighing machines. EYRAUD, I., and EYRAUD, C. Oct. 28, 1952 [Nov. 5, 1951; Dec. 14, 1951], No. 27105/52. Class 40 (1). [Also in Group XL (b)] In a weighing-machine wherein the weight of a body 12 (Fig. 1) is balanced by the electromagnetic force exerted by a solenoid 7 energized by a current determined by a photo-cell 5 whose light input is controlled by a screen 2 attached to the weighing beam, the moving system is such that its centre of gravity is located on the fulcrum 19 by adjusting the position of a weight 20, so that equilibrium is fully determined by the current in coil 7 and is independent of the angular disposition of the beam. The current in'coil 7 is proportional to the weight of the body 12 and is measured across a series resistor 8. It may be augmented by a current proportional to its rate of change derived from the amplifying circuit (not shown) to provide damping. The coil 7 is preferably shaped so that the force on a core 18 is independent of the position of the core in the coil. The core 18 may alternatively be a coil fed with a constant current or with the same current as the main coil 7.

Abstract: 355,058. Moulding caps for electric lamps and valves. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Severance, S. W. ; 653, North Street, and Kessler, J. W. ; 17, Hazelwood Terrace, both in Pittsfield, Massachusetts, U.S.A.) Sept. 11, 1930, No. 27158. Convention date, Sept. 11, 1929. [Class 87 (ii).] A moulded cap for a valve or lamp is produced in a multi-section mould by providing each contact pin with a head of over-size dimension, compressing the head between two sections of mould so as to reduce it to proper dimensions, and moulding the cap about the pins. As shown in Fig. 2, the head 5 of each contact pin 2 is formed with a conical top and with two flanges 7, the upper one of which is knurled. The pins are inserted in recesses 10 in a lower mould section 9 which is forced against an upper mould section 12 so that the conical heads are flattened and the lower flanges are forced into recesses in the section 9. The section 9 and an outer cylindrical section 15, which surrounds it loosely and rests on a platform 14, are lowered, moulding material such as phenolic condensation product is inserted and the sections raised so as to mould the material about the contacts, the mould being heated during this operation by the passage of steam through conduits 18 ; excess material is forced out at the top as shown in Fig. 5. The section 9 is again lowered, the outer section 15 being held by an obstruction, not shown, and the cap is removed by inserting knock-out pins in the recesses 10. The operations of flattening the heads and moulding may be carried out simultaneously. A number of caps may be made in a multiple mould.

Abstract: Gas generating charges capable on local heating of non-detonating decomposition comprise mixtures, including thermally vapourizable pesticides such as D.D.T. or g -hexachloro-cyclohexane, in compacted form whose other constituents comprise guanidine nitrate and a polynitro- or polynitroso-derivative of phenol or a hydroxy-, carboxy-, or methyl substitution derivative of a phenol, e.g., 2 : 4-dinitro-resorcinol, 2 : 4 : 6-trinitro-resorcinol, 2 : 4-dinitroso-resorcinol, 4 : 6-dinitro-ortho-cresol, 3 : 5-dinitro-catechol, 2:6-dinitro-para-cresol, or 3:5-dinitro-salicylic acid, in which mixtures the guanidine nitrate is in a preponderating proportion over the other constituents and the polynitro- or polynitroso-derivative is present in sufficient proportion to render the mixture capable of sustaining its own decomposition.  8-20 per cent of the weight of guanidine nitrate may be the proportion of polynitro- or polynitroso-derivative, or less if tartaric, maleic, citric or fumaric acids are present.  Vanadium pentoxide, say 0.2-1 per cent of the weight of guanidine nitrate, or a chemically equivalent compound such as ammonium vanadate, or a molybdenum compound such as molybdic acid may be included.  Condensable organic compounds in the gases may be removed by adding 0.25-1 per cent of a heat-resisting material having a large surface area such as asbestos fibre, or by passing the hot gases over heat-resisting catalytic solid surfaces, e.g., iron, steel, or platinum wire gauze, inserted in a central perforation in the compressed charge. Potassium nitrate, say 0.25-1 per cent and compounds to raise or lower the gas temperature, such as ammonium perchlorate or nitrate may be added. The ingredients may be mixed in a ball mill and the mixture may be in powder, granular, or compact form; if in compact form the composition may be provided with an adherent covering of heat-insulating material, e.g., asbestos sheet or paper, during pressing.  An example includes mineral oil. Specifications 21529/05, [Class 9], and 620,600 are referred to.

Title: Improvements in or relating to micro-wave radio scanning arrangements
Inventor: RAMSAY JOHN FORREST
IPC: H01Q3/14
Filed: 1950-11-10
Abstract: 695,031. Directive radio systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 4, 1951 [Nov. 10, 1950], No. 27568/50. Class 40 (vii). A micro-wave radio scanning arrangement comprises a series of angularly spaced primary elements, means for driving said elements simultaneously along circular paths arcs of which traverse the focal surface of a lens or mirror to be scanned and have the same centre, a common feed guide, and a wave-guide switch arranged to connect the elements successively to the guide during the periods that its arc of movement is traversing the area to be scanned. For scanning an approximately rectangular area a disc 5 may be mounted for rotation on an axle 3 carried in a bearing 2 mounted on a supporting structure 1, the disc carrying equiangularly spaced horns 6 arranged on a spiral path on the disc and arranged so that they traverse the focal surface of a lens or mirror (not shown). If there are 8 horns, 6 (Fig. 2), an area Y corresponding approximately to a rectangle X will be scanned in 8 lines. The horns 7 are connected to the rotating part 8 of a rim-shaped wave-guide switch which is completed by the fixed part 9. The parts 8 and 9 are separated by a small gap, leakage being prevented by " ditches " 13. The feed guide 10 is teed into the part 9 of the switch guide and stubs 11 arranged so that power is fed to or from the system only in the direction shown by the arrow H. The guides 7 connecting the horns 6 and rotating switch part 8 are each followed by similar stubs 12 on their sides distant from the feed direction so that only the horn nearest to and anticlockwise from the feed guide is connected thereto electrically. To compensate for sector distortion the feed points may be unequally spaced round the ring 8 as indicated. The invention may be limited to line scanning with all the horns equidistant from the axis of rotation of the disc and a flat horn suitably distorted at its input end to fit the arc swept out by the horns 6 used between the said horns and the lens or reflector. In another line-scanning variation the disc is arranged parallel to the flat horn which will then not require distortion. The energy path length of the system varies during the scanning of each horn from a maximum at the beginning to a minimum at the end of each scan. This may be compensated for by means of a second ring switch coaxial with the first and arranged to introduce oppositely varying path lengths. Two spirals of horns on the disc 5 may be used to give interlaced scanning.

Abstract: 840,734. Brake shoes. DAMIRON, P. Sept. 10, 1956, No. 27630/56. Class 103 (1). In a brake shoe comprising a body 4 and a chamber 15 formed within the body adapted to receive and hold a fluid therein, one wall 17 of the chamber constitutes the friction bearing surface and consists of a thin, flexible heatconducting material and the chamber 15 is connected to a source of fluid under pressure. The brake shoes 4 and 5 of the internal shoedrum brake arrangement shown in Fig. 1 are formed of two fabricated metal sections 18 and 19 welded together to form a cavity 21. Stretched across the opening of the cavity 21 is a thin flexible heat-conducting strip 17 gripped and folded under edges of the sections 18 and 19. A plastic lining 22 ensures that the chamber 15 is fluid-tight. Cooling fluid such as water or glycol is circulated through the chamber 15 in each brake shoe through inlets 23, 24 from a pump (not shown) and from the chamber in each brake shoe through outlets 29, 30 leading to the cooling fluid reservoir and heat exchanger (not shown). Inlet check valves 25, 26 permit entry of cooling fluid only when the pressure in the inlet conduits 23 and 24 exceeds a predetermined value and outlet check valves 27, 28 permit flow of fluid from the chambers 15 only when the pressure therein exceeds a predetermined value. A modification is disclosed in Fig. 5 in which the wall forming the friction bearing surface of the shoe is flush with the ends of the brake shoe body at the end of the cavity. Reference has been directed by the Comptroller to Specification 775,052.

Title: Improvements in locks or latches
IPC: E05B21/00
Filed: 1952-11-04
Abstract: 740,700. Locks and latches. ASH, J., ROGERS, A., and ROGERS, A. L. Nov.-4, 1953 [Nov. 4, 1952], No. 27697/52. Class 44. A lock or latch has guides between which the body portion of a lock or latch bolt 5 is slidably supported and guided, the guides being projections 4, 6 on a separate liner or mounting plate or member 1 fitted in the case 2. The invention is shown applied to a lock and the projections 4, 6 are formed as flanges on the plate 1. Slidably mounted between the plate 1 and the rear face of the case 2 is a sliding tumbler 8 the liner plate having projections 9 which bear on the rear face of the case to allow space for the tumbler. The tumbler has a flange 10 which projects through a slot 3 in the plate 1, a flange 11 which projects through a slot 12 in the plate 1 and a flange 13 which projects upwardly adjacent the flange 6 to the side of the plate 1. The bolt 5 has a cut-away control part 5b, arranged so that a flange 15 is formed at its tail end, and a recess 17 at its head end. This cut-away part of the bolt straddles the flange 10 of the tumbler and a cut-away part of the flange 6 of the liner plate. A double S-shaped spring 16 engages a wall of the casing, the flange 11 and the recess 17 so that the tumbler is urged downwardly and the bolt to its latching position. In the unlocked condition the inner face of the flange 15 on the bolt abuts the flange 13 on the tumbler and thus the projection of the bolt from the case is limited. In this condition the bolt can be retracted by a clockwise rotation of a key to engage the front of a projection 5a on the bolt. A pin 18 for the key projects through a hole in the plate 1, its head bearing on the case 2. 'The bolt is projected further from the casing for locking and to do this the key is rotated anti-clockwise to first raise the tumbler 8 so as to free its flange 13 from the bolt flange 15. This frees the bolt which moves outwardly until its flange 15 engages the cut-away part of the flange 6; the flange 13 on the tumbler can thus move behind the flange 15 of the bolt so that the bolt is locked. Movement of the tumbler is limited by its flange 11 engaging the base of the slot 12 on the plate 1. The flanges 4, 6 are the height of the lock case and are engaged to hold the plate 1 in position by a cover-plate for the lock. This cover-plate also slidably engages the bolt to hold it in position.

[Also in Division F4] In a gas-fired water heating apparatus having a control arrangement for the burners including time delay control valves (see Division F4), each such valve has a body part 41 divided by an intermediate wall 44 into an inlet chamber 45 and an outlet chamber 46 connected by an opening 54 in wall 44 having a valve seat 55 normally closed by a valve plate 56 lightly biased by a spring 57. Control diaphragms 58, 62 are mounted on the body 41 in spaced relation and are connected to the valve stem 65, the chamber 69 between upper diaphragm 62 and valve cover 63 being connected to chambers 72, 74 by an opening 71 having a restricted orifice 85 and an opening 73 respectively, the latter having a flap-valve 82. Chambers 72, 74 which are disposed in a boss 75 are closed by a top plate 78 and are connected by a passage 76, the chamber 74 having a control inlet 77 connected to the gas supply via a solenoid operated valve 22. When valve 22 is opened to supply gas to the burners the gas enters inlet chamber 74 but is prevented from entering opening 73 by the closed flap valve 82 and passes via passage 76 to chamber 72 where the orifice 85 delays its passage into chamber 69. After the time delay the pressure in chamber 69 becomes sufficient to overcome the pressure exerted on diaphragm 58 and lower the valve plate 56. When the control pressure is cut off the gas within chamber 69 is rapidly vented through flap valve 82 and the valve closes.

Abstract: 1426830 Automatic frequency control PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 12 June 1973 [15 June 1972] 27827/73 Heading H3A In a television receiver Fig. 1, the separated out field sync. pulses are fed to one input of coincidence detector 20 for comparison therein with the output of twice line frequency oscillator 11 as divided down by 625 (number of lines in frame) by divider 15. Lack of coincidence lasting more than a predetermined time (as determined by integrator 21 and level detector 22) causes the divider 15, to change its division factor to 633 and produce a train of pulses which hunt past the field sync. pulses at detector 20 until a coincidence is detected. The division factor of divider 15 is then changed back to 625. The change of the division factor is commanded via a memory 25 such that with a weak signal erroneous action due to interference pulses is avoided.
