Title: Improvements in and relating to composite building units
Filed: 1948-05-19
Abstract: 651,542. Girders ; floors ; walls; building units. PERRY, A. R., and BUILDING TECHNIQUE, Ltd. May 19,1948, No. 13522. [Classes 20(iv) and 87(i)] Beamlike elements as for flooring or used on end for walling are made by moulding concrete &c. on flexible sheeting, e.g. impermeable paper or metal, or sheet material such as wallboard, supported upon and freely suspended from metal side plates which are connected by spacing members and constitute shuttering. Flooring units, e.g. 12-20 in. wide and up to 12 feet long, comprise side sections 1 of sheet steel with longitudinal dovetail grooves 2 and internal spacing rods, angles &c. 3, supporting impermeable paper sheeting 4 preferably in the form of a continuous band wrapped round the framing at one end of the unit and the two ends being tensioned at the other by a roller carried on an end mould member. Reinforcement, e.g. expanded or stamped sheet metal 14, may be laid on the paper and concrete is then applied to the level of the side sections on one side and when this has hardened to the other. To prevent the paper sagging, longitudinally arranged light metal ribbon may be stretched round the unit. A succession of units may be propelled to moulding, vibrating, levelling, and drying stations by the engagement in the grooves 2 of rollers supported on horizontal axes from longitudinal frames providing the runway. Asbestos board or other wallboard &c. may replace the paper support and may be gripped in grooves in the side sections so as to be outwardly cambered; or the spacing members may be cambered. Light metal corrugated or other sheeting may be used instead of paper. Keying apertures, stiffening ribs &c. may be provided in the side sections. In modifications the spacing rods are grouped and lapped with paper so as to delineate in section truncated triangles or rectangles, the gaps between them being filled with concrete to form struts between the two facings. In laying a floor the units are disposed side by side with a slight clearance between each pair and are locked together by clamps 41, 42, engaging in the grooves 2, and expanded as by a rod 44 having threads of opposite hand, or a single clamp with two dovetail projections may be rotated into locking position by a tommy bar. After insertion of a wallboard &c. fillet at the base of the clearance by means of a clip which engages grooves in the side sections concrete &c is filled in up to floor level.

Title: Improvements in or relating to the incorporation of exposure meters in photographic cameras for use with interchangeable lenses
IPC: G03B7/04
Filed: 1951-06-07
Abstract: 697,197. Photographic cameras combined with exposure meters. ZEISS IKON AKT.-GES. June 7, 1951 [June 7, 1950], No. 13550/51. Class 98 (i). [Also in Group XL (b)] A camera for use with two or more interchangeable lenses and incorporating an exposure meter includes means for taking into account the different speeds of said lenses in operation of the meter, said means comprising an adjustable member movable over a scale of lens speeds, movements of said member being transmitted independently of the lens diaphragm adjustment of the camera to the exposure meter through gearing adapted also to transmit to the meter setting movements for other exposure factors, e.g. exposure time or film sensitivity, so that the same sensitivity of the meter may be obtained whichever lens is in use since the light reaching the meter is the same for each lens. As shown, an aperture selecting wheel 3 is geared to the toothed rings 1, 6 of diaphragms for the camera objective and a photo-cell 7 which operates an electrical meter 8. A mark 10 carried by a disc 9 is brought into register with the meter pointer by adjustment of a shutter speed setting disc 14 which through a differential gear 13 rotates a worm 12 engaging the toothed edge of the disc 9. Allowance for film speed is made by adjustment of a disc 15 connected to the gear 13. To make allowance for different interchangeable lenses, a further differential gear 16 is provided between the worm 12 and the gear 13 and is adjustable by a lever 17 against a scale of f-numbers.

Title: Improvements in or relating to line timebase circuit arrangements
IPC: H04N3/233
Filed: 1964-04-02
Abstract: 1,043,623. Sawtooth circuits; cathode-ray tube circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES. April 2, 1964 [April 5, 1963], No. 13644/64. Headings H3P and H4T. In television apparatus for correcting trapezium distortion by amplitude modulation of the horizontal deflection current at the frequency of the vertical deflection wave, asymmetry of the raster is reduced by varying the magnification Q of the output circuit in the same sense as the amplitude modulation. Fig. 2 shows a horizontal deflection circuit in which the output valve 1 is controlled by waveform 2 so as to provide a sawtooth current in horizontal deflection coils 6, the amplitude of the deflection current being modulated by the vertical deflection waveform 12 which, after amplification by valves 11, 10, varies the voltage across the H.T. boosting capacitor 9. The magnitude of current in coil 6 at the end of each flyback is made equal and opposite to that at the beginning of the next flyback so as to reduce asymmetry in the raster. This is achieved by positive feedback of the flyback pulses to the grid of valve 25 which is connected to an auxiliary coil 7, the amplitude of flyback pulses being modulated at 22 by the vertical deflection wave 12. This has the effect of reducing the magnification of the resonant flyback circuit in accordance with the magnitude of the modulation. In Fig. 4 the modulation of horizontal deflection current in coil 6 is achieved by modulating the driving waveform 2 fed to the grid of the horizontal output valve 1. Waveform 2 is derived by charging a capacitor 30 from a cathode follower 29 controlled by a valve 27 the output of which is dependent upon the difference in the voltage across the H.T. boosting capacitor 9 and a voltage at the anode of valve 11, derived from the vertical deflection waveform 12. Capacitor 30 is discharged by a transistor 32, turned on by each horizontal synchronizing pulse 33. The low frequency (vertical) component of the waveform is extracted from the cathode of valve 1, used to modulate the flyback pulses at 22 and control the current of auxiliary valve 1<SP>1</SP> in such a way that the mean value of the combined anode current for valves 1, 1<SP>1</SP> is constant and hence an asymmetrical raster is avoided. In Fig. 5 (not shown) valve 1<SP>1</SP> is omitted and the output of modulator 22 fed to the grid of valve 1. In Fig. 3 (not shown) the modulation is achieved by the method shown in Fig. 4, whilst the asymmetry control is achieved by the method shown in Fig. 2. The valves may be replaced by transistors.

Title: Improvements in heat transfers
IPC: B44C1/17
Filed: 1937-05-18
Abstract: A vinyl resin is used as the basis of a transfer ink adapted to be released from a paper base and rendered adhesive by the application of heat and pressure so as to produce a tough flexible marking on articles which have to resist abrasion and distortion such as tennis balls, conveyer belts &c.  In order to regulate the fusibility, cellulose derivatives or the like, or plasticizers such as butyl phosphate, tricresyl phosphate, triphenyl phosphate, or butyl phthalate may be added.  To facilitate stripping of the backing after application to the article to be decorated, there may be added a lubricant which is not completely dissolved in the composition when cold, e.g. an oil or wax, a soap such as magnesium oleate or triethanolamine stearate, oleate, or linoleate, or a fatty acid such as stearic or oleic acid; also a smooth impervious paper such as glassine is used.  Dyes, pigments, &c. metallic powders may also be added.

Title: Improvements relating to data storage devices
Inventor: FROGGATT ROBERT JUSTIN
IPC: G11C11/06
Filed: 1957-04-30
Abstract: 893,351. Circuits employing bi-stable magnetic elements. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 25, 1958 [April 30, 1957], No. 13793/57. Class 40 (9). [Also in Group XIX] A data store comprises control circuits, energized in a predetermined sequence, for controlling the input and output of data signals relative to each storage location, switchable devices, associated with the storage locations, for registering the operations of the control circuits, and means responsive to the switchable devices for indicating the full or empty condition of the store. The magnetic core matrix store shown acts as a buffer between a computer and a tape or other input/output devices. Words entered in parallel on lines 1-3 are written in successive rows under control of a write distributer comprising cores 6-9, and the rows are read out in parallel to lines 25-27 successively under control of a read distributer comprising cores 17-20. The write and read control output lines from the distributers are so connected, via windings on the matrix cores, to windings on indicator cores 28-31 that as a row is written in, current through a circuit including matrix windings such as 50a, 51a, 52a for the first row, tends to drive a pair of indicator cores, one to a first state and the other two a second state, and as a row is read the same pair of cores tend to be driven to the opposite states. The initial states of the indicator cores are such that for writing an output pulse is normally obtained at 32 which through a circuit, similar to that described in Specification 893,355, including condenser 33 and transistor 34, inhibits the setting of a core 36 by a " write " pulse from terminal 5. When however, the last row is written in, the corresponding two indicator cores (30 and 31) are both in such states as to be switched over by the driving current, the outputs at 32 then cancelling each other out. Core 36 is therefore set to indicate that the store is " full." This condition is detected at 40 in response to a pulse at winding 39, the core being reset to the " full " state by feed-back through transistor 37. Similarly, during reading, the setting of core 41, by a " read " pulse from terminal 4, is inhibited until the last row is read when the core is set to indicate that the store is " empty." When one of the cores 36, 41 has been set, cross-coupling between the cores inhibits the setting of the other in response to the first " read " or " write " pulse.

[Class 461 A rotary filter, particulary for dewaxing mineral oil, comprises a drum 15 mounted to rotate in a vat 13, the periphery of the drum being built up of segments separated by partitions to form filter chambers beneath a cloth wrapped round the drum. Each chamber is connected by a pipe such as 20 extending radially to the hollow journal 10 and then longitudinally to a valve plate 16 which abuts against a stationary plate 17. The valve plate consists of an outer annular plate 22, an inner circular offset plate 23 and a connecting ring 23a. The face plate 17, which is held against the valve plate by means of tie-rods 24, comprises a circular piece 25 with flanges 26, 27 forming an annular chamber 28. The plate 17 carries plugs 35, each threaded on an adjustable valve stem 36. By turning the stem, the plug 35 may be moved to open communication between a pipe 20 and the chamber 28. The plug is less than half the width of the chamber 28, so that when one plug is completely closed to shut off communication between the chamber 28 and the pipe 20, while adjacent plugs are completely open, there is still a communicating space in the chamber 28 around the closed plug 35. An adjustable plug is provided for each pipe 20 except for a permanently positioned plug 42 covering an extent corresponding to three filter segments. This plug has a bore 43 connected to means for blowing gas for the purpose' of removing filter cake. Face plate 17 is provided with lugs 48 having slots 49 to receive the tie-rods 24 so that the plate may be adjusted with respect to the valve plate 16. In operation of the filter, the tank 13 is partly tilled with wax slurry and suction is provided on connections 32, 33 leading respectively to tanks for receiving oil filtrate and wash filtrate. With the plugs 35 open, wax cake will be built up on the filter olements as the drum 15 rotates, the oil filtrate being drawn off through the pipe 32. As the tilter surface emerges from the wax slurry it is washed by solvent, by means (not shown), and dried by suction through the pipe 33. Thereafter the cake is discharged by blowback gas through bore 43, the cake falling into a trough 45 and being conveyed to a spout 47.
