Title: X-ray exposure timing apparatus
IPC: H05G1/60
Filed: 1974-01-18
Abstract: 1453358 Automatic control SIEMENS AG 18 Jan 1974 [19 Jan 1973] 2520/74 Heading G3N X-ray exposure timing apparatus comprises computing circuitry operable selectively appropriate to a plurality of different exposure programmes employing a given x-ray tube and provide indication that the apparatus can be used to repeat a selected programme. As shown, a preferred exposure programme for an x-ray diagnostic installation is selected by a function key 1-3 which activates a relay A-C, having contacts a-c. The relay A selects through contacts a1-a5 desired power, voltage, image frequency and take-time, and through a contact a6 selects a resistor 18, simulating anode heating, for charging a capacitor 17, and a resistor 21, simulating anode cooling, for discharging the capacitor. The take-time is initially indicated on a device 6 and set in a switch 8; the exposure commencing with the depression of a key 10, which zeros the device 6, and opens an AND-gate 12 to allow the capacitor 17 to charge. At the end of the taketime the switch 8, through a line 9, terminates the exposure and through an OR-gate 16, switches a transistor 27 to initiate the discharge of the capacitor 17. When the discharge reaches a threshold valve of a triggering member 28 a signal is sent over a line 29 to cause device 6 to again indicate the take-time. The opening of key 10, before the end of the take-time, causes the transistor 17 to be switched through a inverter 15 and the OR-gate 16.

Title: Improvements in refrigeration systems
Inventor: MARLO ANGELO THOMAS
IPC: F25B1/00
Filed: 1963-01-21
Abstract: 991,339. Refrigerating. MARLO COIL CO. Jan. 21, 1963, No. 2557/63. Heading F4H. In a compression refrigeration system having a condenser and liquid receiver, means are provided for heating the refrigerant in the receiver when the pressure therein falls below a predetermined level. As shown, the receiver 40 is heated by hot gaseous refrigerant which is forced to flow in a line 34, part of which is disposed in receiver 40, when a valve 32 in the compressor discharge line closes in response to a fall in pressure in the receiver. A check valve 38 is located between the condenser 36 and the receiver so that when the pressure in the receiver begins to rise, due to the heat supplied by pipe 34, this valve closes causing liquid refrigerant to back up in the condenser and thus increasing the condenser pressure. Eventually the latter increases sufficiently to cause valve 38 to open and normal operation is resumed, the valve 32 having been opened when the receiver pressure reached a predetermined value. In a modification (Fig. 1, not shown) the valve 32 and the line 34 are omitted and an electric heater, which is controlled by a pressure responsive switch, is provided in the receiver.

Title: Inertia electric switch
IPC: H01H35/14
Filed: 1959-01-26
Abstract: 852,008. Inertia switches; switches, partly magnetic. CLURMAN, S. P. Jan. 26, 1959, No. 2757/59. Class 38 (5). An inertia switch adjustable to respond to a range of accelerations comprises a magnetic electrically conductive ball 19 normally seated in a recess 18 in an electrode 13 pressed into an insulating sleeve 11 inside a casing 10 having apertures for connecting leads to electrode 13 and to an annular electrode 12 respectively. The electrodes 12 and 13 and casing 10 are of non-magnetic electrically conductive material such as brass, copper or aluminium. A cylindrical permanent magnet 22 or equivalent electromagnet is carried on a threaded plug member 20 which may be screwed axially by a tool inserted in slot 21 to adjust the distance of the magnet 22 from ball 19. Acceleration perpendicular to the axis of the magnet, and sufficient to overcome the restraining effect thereof, causes ball 19 to bridge electrodes 12 and 13. When the acceleration ceases the magnet 22 restores the ball to the original position shown. Instead of a special electrode 12 the top part of the casing may be insulated from the lower part (Fig. 3, not shown) and the ball serves to interconnect the two parts when accelerated. In this case leads are not necessary as the switch may be held in a conventional spring clip fuse holder. Figs. 4 to 7 (not shown) illustrate two embodiments wherein the ball is surrounded by an annular member of magnetizable material such that after acceleration it is held in the operated condition by magnetic attraction and a spring-loaded plunger has to be depressed to restore the ball to the central position. In the embodiment of Fig. 4 (not shown) the ball normally bridges a gap between two semi-circular plates which form its seat, and when subjected to acceleration the circuit is opened. In another embodiment (Figs. 8 to 10, not shown) the magnet comprises a hollow cylinder with its axis horizontal and acceleration in the direction of this axis causes a ball to follow a helical path and a time delay, dependent upon the pitch and number of turns of this helix, is thus introduced between the acceleration and switch closure. It is stated that the magnet causes the ball to return along the helical path when the acceleration ceases. Whilst a helical path is preferred any other suitable tortuous path may be provided. In the earlier embodiments the recess 18 forming the seat for ball 19 need not be conical but may have different slopes to provide differing sensitivities to accelerations in different directions, or the possible movement of the ball may be limited to one particular direction.

Title: Improvements in or relating to the preparation of organic phosphates
IPC: C07F9/12
Filed: 1948-01-30
Abstract: Monoalkyl and monoalkoxyethyl diaryl phosphate esters having the general formula <FORM:0656471/IV (b)/1> in which R is a phenyl or cresyl residue and R1 is an alkyl radical containing at least 6 but not more than 12 carbon atoms or an alkoxyethyl group in which the alkyl substituent has at least 4 but not more than 12 carbon atoms, are prepared by reacting one molecular proportion of phosphorus oxychloride with substantially one molecular proportion of an aliphatic alcohol having at least 6 but not more than 12 carbon atoms or an alkoxyethylene glycol in which the alkyl substituent has at least 4 but not more than 12 carbon atoms and reacting the alkyl or alkoxyethyl phosphoryl dichloride thus produced with an alkali metal salt of phenol or a cresol.  The products are plasticizers for polyvinyl chloride and vinyl chloride copolymers, in connection with which reference is made to Specification 656,510, [Group IV (a)].  In examples: (1) 2-ethyl hexyl diphenyl phosphate is prepared by adding ethyl-hexanol to cooled phosphorus oxychloride with stirring, evolved hydrogen chloride being removed continuously by vacuum applied to the reaction vessel and the resulting ethyl-hexyl phosphoryl dichloride is added to an aqueous solution of sodium phenate; in like manner (2) 2-ethyl hexyl dicresyl phosphate, (3) lauryl diphenyl phosphate and (4) 2-methyl pentoxyethyl dicresyl phosphate are prepared.  Other esters mentioned include n-hexyl diphenyl and dicresyl phosphates, n-octyl diphenyl and dicresyl phosphates, n-decyl diphenyl phosphate, n-butoxyethyl diphenyl phosphate, lauroxyethyl diphenyl and dicresyl phosphates and a mixture of alkyl diphenyl or dicresyl phosphates in which the alkyl residues are obtained from a mixture of aliphatic alcohols derived from coconut oil of which substantially 60 per cent of the alkyl radicals contain at least 8 and not more than 12 carbon atoms.  The Specification as open to inspection under Sect. 91 describes a preparation of the above-mentioned esters which comprises reacting phosphorus oxychloride with the alcohol or alkoxy ethylene glycol and an alkali metal phenolate or cresylate.  This subject-matter does not appear in the Specification as accepted.
Patent GB-568563-A (GB)
Title: Improvements in and relating to the cracking of heavy oil vapours
IPC: C10G9/42
Filed: 1940-02-15
Abstract: Heavy oils boiling above 300 DEG  C. are cracked by passing the vaporised oil, diluted with not less than 1 per cent and not more than 10 per cent by weight of inert gaseous diluents and with not more than 3 per cent of an oxidising agent, e.g. steam or carbon dioxide through a tube the reacting surfaces of which are oxidised or coated with iron oxide and which is maintained at a temperature of at least 600 DEG  C.  A hydrocarbon diluent is preferably used which will be converted under the reaction conditions, e.g. ethylene which is converted to propylene or light paraffins which are converted to higher olefines.  Oil vapours (b.p. 300 DEG  C. upwards) containing .5 per cent by weight of steam are mixed with ethylene and the mixture is passed at the rate of .2 litres per minute through an oxidised iron tube 10 inches long and 1 inch in diameter, 40 per cent of the product obtained boiled below 200 DEG  C.

Title: Improved racing game
Inventor: LACK WILLIAM THOMAS
IPC: A63F9/14
Filed: 1958-01-29
Abstract: 881,084. Magnetic race games. TOOGOOD & JONES Ltd. April 29, 1959 [Jan. 29, 1958], No. 2916/58. Class 132(2) Models 14 representing racers, e.g. horses are drawn along the upper surface of a non-magnetic sheet 10 by magnets 30 each mounted in a block 29 fixed to an endless cord, band or chain 28 trained over pulleys or sprockets 24 disposed beneath sheet 10 and adapted to be rotated by handles 25. The pulleys 24 are mounted on spindles 23 carried by a second sheet 15 so spaced from sheet 10 that blocks 29 fit between them and are guided round the pulleys at the ends of the track. The upper surface of sheet 10 is marked as a race track with start and finish. Tn the form shown in Figs. 4 and 5, the magnetic axes of the magnet in the model and the magnet 30 lie along the length of the track so that the model tends to keep its direction. One or other of the magnets can be replaced by magnetic material. At intervals along the track thin transverse strips 39 on the sheet 10 have tapered .edges and simulate jumps which must be negotiated at the right speed lest the magnet 30 run ahead of the model. Strips 39 carry pairs of fences 40 forming lanes 41 one in the path of each model as it proceeds in one direction only. One fence of each pair 40 is so disposed that it would be fouled by the model which must therefore be diverted slightly from its usual path to go through the lane 41. This is effected by a pin 44 lying between the runs of cord 28 and adapted to be swung by handle 47 to one side to move the cord and magnet 30 slightly transversely at the appropriate point. The motion of handles 25 may be transmitted to pulleys 24 by flexible cables. In a modified form, Fig. 9, the model has its lower surface formed with a leading curved part 51a fitted with a vertical magnet 52 and separated from a lagging part also having a vertical magnet 53 by an obtuse angled part 51b. Magnets 52, 53 have opposite poles downwards. The track has vertical transverse strips 50 of varying heights representing fences. As the magnet 30 advances, part 51a hits strip 50 and after further motion of magnet 30 the lagging pole thereof will repel magnet 52 to lift the front of the model over the strip 50 which comes to rest in the angle 51b. The magnet 30 is then moved back slightly, attraction causing the model to tip forwards, and then the magnet can be moved forward again to pull the model off strip 50 and continue progress. The apparatus may have a glass cover and be coin freed. According to the Provisional Specification, magnets 30 may be advanced electrically or maybe replaced by free magnets manipulated by hand beneath sheet 10.

Title: Improvements in dipole antenna systems
IPC: H01Q9/16
Filed: 1945-02-06
Abstract: 592,760. Aerials. STANDARD TELEPHONES & CABLES, Ltd., and WILLOUGHBY, E. O. Feb. 6, 1945, No. 3047. [Class 40 (v)] A broadband dipole antenna system, especially for use on aircraft, comprises two conducting elements to each of which one conductor of a feeder is connected, each element being electrically unbalanced with respect to earth about its feed point, the elements overlapping along the whole of their lengths so that the system is electrically balanced with respect to earth about a point intermediate of its ends. The ends of the overlapping elements are joined so that their oppositely disposed edges constitute short-circuited transmission lines, the design being such that the reactance changes at frequencies differing from the resonance frequency are substantially equal and opposite to the changes of the series resonant circuit formed by the equivalent overall dipole across the feeder. The antenna, Figs. la, 1b and 1c, comprises a conducting member 1 of streamlined cross-section with a Z-shaped slot 2 extending longitudinally as shown on both sides. The member 1 thus slotted comprises two overlapping elements consisting of the portions 4 5 and 6, 7 respectively, joined by end portions 8 and 9 respectively. The element 4, 5 is connected to the outer conductor 10 and the element 6, 7 to the inner conductor 11 of a coaxial feeder, the outer conductor 10 forming a support. By this arrangement the portion 4, 8 of the element 4, 5 has a greater capacity to earth than the portion 5 on the opposite side of the feed point and similarly the portion 6, 9 of the element 6, 7 has a greater capacity to earth than the portion 7, the effective dipole being formed by the difference of the capacities to earth of the elements on each side of the antenna. In the arrangements of Figs. 2a, 2b, 2c (not shown), the antenna is formed of a tubular member of streamlined cross-section closed at its ends and divided by central transverse slots into two portions. One portion is divided along its upper surface by two longitudinal slots leaving a central tongue and the other portion is similarly divided along its under-surface by .slots leaving a tongue. In a further arrangement, Figs. 3a, 3b, 3c (not shown), the antenna is in the form of a cylindrical member closed at its ends by conducting discs, the member being slotted in the same way as in Figs. 2a, 2b, 2c. The lengths of the shortcircuited transmission lines constituted by the longitudinal slots in the various embodiments may be designed of such length as to be antiresonant at the mid-band operating frequencies If the transmission lines are less than #/4 at the mid-band frequencies, a condenser may be provided as illustrated in Fig. 4 (not shown). The capacity of this condenser may be varied by a control extending outside the antenna. Alternatively, these slot transmission lines may be shortened electrically by filling the tubular members and slots with suitable dielectric material.

Measuring-apparatus.-Into the cooling-water supply circulation system of a compressor or in. ternal-combustion engine, a flap or valve &c. is disposed so as to be balanced by the normal water pressure against the action of a weight &c., and, on failure of the pressure, automatically rotates a spindle fitted with an external weighted lever, spring, &c., to indicate the failure audibly or visibly. As shown in Fig. 1, a flap-valve &c. c, located in an extension of the water-supply pipe, is mounted on a spindle weighted on one side and carrying a lever supporting a block j of insulating- material on the other. When the supply fails and the valve rises under the action of the weight, the block j closes a switch k, m, which may be in the circuit of an electric bell or light. In place of, or in addition to, the switch, trip-gear may be used, comprising a tail-piece q on the valve spindle, adapted to strike the pin of a pawl s and thus free a lever u on the spindle of a cock disposed on a pipe supplying compressed air to a whistle y; the cock is thereupon opened by a spring w. Alternatively, the spindle of this cock may be operated directly from the spindle of the flap valve. In place of a flap valve, a disk-valve may be employed, the spindle of which carries a block adapted to open or close a switch.
