Patent GB-943680-A (GB)
Title: Ampoule applicator
IPC: A61M5/28
Filed: 1962-07-27
Abstract: 943,680. Hypodermic syringes. OTTO KONIGSLOW MANUFACTURING CO. July 27, 1962 [Aug. 7, 1961], No. 29016/62. Heading A5R. A surgical syringe for receiving and discharging the contents of an ampoule A comprises a plunger 7, a spring 31 for projecting the plunger, a lost motion connection 18, 19 between a spring compressing member 16 and the plunger and manually operable toggle means 22, 24 which retracts the plunger when moved in one direction and compresses the spring when moved in the opposite direction, a releasable latch 11 securing the plunger against projection when the spring is compressed. A collapsible ampoule A comprises a disc 40 having a central boss 41 and sealed to a flexible plastic cup 42, a metal disc 45 sealed in the cup carrying a hypodermic needle 41, the inner end of which is open to medicament in the ampoule. The ampoule is inserted laterally into the forward end of the syringe and is centred by engagement between the boss 41 and a notch 35 in a retaining plate 34. Toggle links 22, 24 are pivotal on the spring compressing member 16 and a pin 25 connected to the casing, respectively, one link 24 being integral with an operating handle 29. The spring compressing member has a slot 18 in which a pin 19 attached to the plunger is slidable, thus forming a lost-motion coupling. On pivoting the handle 29 away from the casing, the spring compressing member and the plunger are retracted until a spring-urged latching pin 11 in the plunger engages a hole in the side of the casing to lock the plunger in retracted position. To cock the syringe, the handle is returned to lie along the casing, thus causing the toggle linkage to pass through dead. centre position and move the spring compressing member forwardly to compress the spring. To make an injection the handle is then pressed against the side of the syringe so that a projection 30 presses the latching pin out of the hole in the casing to release the plunger. The plunger is then projected by the spring to collapse the ampoule and cause the needle to penetrate the boss 41 and the tissue.

Title: Television receiving systems
IPC: H04N7/10
Filed: 1945-11-03
Abstract: 606,532. Television distribution systems. KALLMANN, H. E. Nov. 3, 1945, No. 29226. Convention date, Oct. 6, 1943. Drawings to Specification. [Class 40 (iv)] An arrangement for distributing television programmes consists of a plurality of antennae each arranged for reception from a different transmitter connected to a common transmission line which feeds a plurality of receivers. The antennae which are of the directional type and tuned to the respective transmitter frequencies may be connected to the transmission line through an amplifier. Filter means are incorporated to prevent interaction between antennae and buffer amplifier to prevent interaction between receivers. In a modification permitting the use of a simplified type of receiver each antenna is connected to apparatus which separates and detects the sound signals which are then used to modulate a low local carrier frequency which is then sent to the line. For one particular programme the audiofrequencies may be sent direct to the line. If the sound signals are frequency-modulated, the usual limiter-discriminator-detector combination may be used to produce the audio-frequency used to modulate the local carrier. At the receiver, after passing through a buffer amplifier the respective sound and vision signals are selected by a pair of filters selectable by a switch from a number of such pairs of filters appropriate to the different programmes.

Title: Wired broadcasting systems
IPC: H04H60/44
Filed: 1975-07-04
Abstract: 1510117 Wired broadcasting systems COMMUNICATIONS PATENTS Ltd 4 July 1975 [4 July 1974] 29594/74 Heading H4R A programme selection button in a subscriber unit of a wired broadcast system is held in a latched position after depression and is only released in response to the receipt from a programme exchange of a digitally coded multibit interrogation signal unique to the subscriber unit, the unit responding to the interrogation signal to emit a signal to the exchange only if the selection button was in the latched position. The arrangement is used for billing purposes in a TV distribution system. To select a programme a latching button 9 is depressed to close contacts 3, 4 and 10. At the end of the programme the exchange applies a low D.C. or A.C. voltage to the programme wires 1, 2 to charge capacitors 12, 13, at each subscriber unit and then transmits in sequence address signals corresponding to each subscriber unit. The address is detected by a unit 19 which supplies an enable pulse to a thyristor 22 and an oscillator 20, the oscillator receiving a second enable input from capacitor 13 if switch 10 is closed to send a response tone to the exchange wires 1, 2. The enabled thyristor causes capacitor 12 to discharge through solenoid 11 to release the latched button 9. In a second embodiment (Fig. 2, not shown) a pair of signalling wires separate from the exchange programme wires is provided, and the oscillator 20 is replaced by an amplifier, the exchange sending after each interrogation signal a reply tone which is only amplified and returned to the exchange as the response tone if the button 9 has been depressed. The response tone may be supplied to the exchange wires throughout the release period of the button so that a faulty release mechanism can be detected at the exchange. The response tone may be a harmonic of the tone received by the amplifier. This may be achieved using a frequency multiplier.

Filed: 1936-10-31
Abstract: 478,845. Pipe joints. SMITH, H. P. Oct. 31, 1936, Nos. 29666/36 and 3957/37. [Class 99 (i)] In a spigot-and-socket pipe joint, the spigot is centralized and secured within the socket bv an elastic member which is applied to the spigot under tension so that its cross-section is reduced; the tension on the elastic member being relieved to effect expansion of the latter after insertion of the spigot into the socket. In the joint shown in Figs. 3 and 4, the elastic member is in the form of a ring b which is located on the spigot a, so as to form a cavity c<3> between itself and the inner end of the socket c, and is split by a tool inserted through a hole c<2> in the socket, the cavity c<3>, hole c<2> and the gap b<1> between the ends of the ring b preferably being filled with cement d. In a modification, two elastic rings are employed, the rings being either in contact with one another or else spaced to form a cement-receiving cavity. Fig. 11 shows a joint in which a length g of elastic material is lapped under tension around the spigot in one or more complete convolutions, the ends g<1>, g2 of the length being released after assembly of the parts. The elastic member may be in the form of a ring, Fig. 13, which is formed into two loops h<2>, h<3> by fixing together, e.g. by vulcanization, spaced parts h, h<1> thereof, the loop h<3> being stretched and applied to the spigot with the loop h<2> projecting outwards and the fixed parts h h<1> being released when the spigot has been inserted into the socket.

Title: Process for obtaining synthesis gas and mechanical energy
IPC: C09C1/48
Filed: 1956-09-28
Abstract: 807.051. Actuating materials; systems of working. DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT VORM ROESSLER. Sept. 28, 1956 [Oct. 1, 1955], No. 29727/56. Class 7(2) [Also in Group XII] In a process of obtaining mechanical energy and synthesis gas and carbon black from the operation of an internal combustion engine, the engine is operated with gaseous or vaporous hydrocarbons in admixture with amounts of oxygen which are insufficient for complete combustion and in admixture with steam water or higher hydrocarbons or hydrocarbon oils. Approximately 0.05 to 15 per cent of the hydrocarbon contained in the reaction mixture may be converted into carbon black. The higher hydrocarbons may be added to the reaction mixture either before or after its introduction into the engine. Suitable higher hydrocarbons are heavy mineral oil fractions or tar oils, which can be either vaporized in the reaction mixture before its introduction into the engine or sprayed into the combustion chamber of the engine before or just after ignition. The steam can be added as such to the reaction mixture or the reaction mixture or one of its constituents can be saturated with steam in a saturator by sprinkling with water of suitable temperature. In this form of the invention, it is advantageous to use the heated cooling water of the internal combustion passed in counter current to the reaction mixture, whereby the reaction mixture is saturated with water and the cool reaction mixture lowers the temperature of the cooling water not absorbed by the reaction mixture and the water can be recycled to the cooling system. Where water is added this can either by vaporized in the reaction mixture before introduction into the engine, or can be sprayed into the combustion chamber. The injection of the water can take place prior to or just after ignition. The injection of water into the combustion chamber can offer particular advantages if at the same time the exhaust valve or the exhaust port of the engine cylinder is already opened, while the inlet valve or the inlet port is still closed. Various additional measures can be used separately or together for further promoting the formation of carbon black. The carbon black formation can be promoted by reducing the oxygen concentration in the reaction mixture. Furthermore, the reaction mixture can be diluted with gases and vapours which are such as not to participate in the reaction. Finally, by intensified cooling, the reaction temperature can be lowered and this also increases the formation of carbon black. The formation of carbon black can be further promoted by diluting the reaction mixture, for example by recycling some of the synthesis gas to the engine. Carbon dioxide is a particularly suitable diluent gas. Carbon dioxide can either be added as such to the reaction mixture or the mixture or one of the constituents can be sprinkled with water which contains carbon dioxide and which is practically always available in plants where synthesis gas is used.

Abstract: 1,176,355. Telecine equipment. COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT. 28 June, 1967 [28 June, 1966], No. 29919/67. Heading H4F. The Specification, describes telecine equipment of the type wherein a raster of flying spot tube T is focused by lens L 1  on a frame of a film F being scanned, the vertical scanning being aided by the movement of the film in the direction F shown, and the following raster, interlaced with the first, is focused by lens L 2  on said frame of film, now moved to the lower position F 2 . When the tube T is moved along the axis to T<SP>1</SP> say, Fig. 2, the positions of the focused frames F<SP>1</SP> 1  and F<SP>1</SP> 2  also move, and the focused frames, as projected on the moving film, no longer interlace. To overcome this and fix the positions F 1  and F 2 , the invention proposes the lateral movement of the lens L 1  and L 2  synchronously with the movement of the tube T. To enable this, the lenses L 1  and L 2  are supported by a cam C, Fig. 4, moving with the tube T, such that movement of the tube T towards the film causes the lenses to draw together and vice versa. Alternatively, the cam C may support only one lens, the other being fixed. The cam surfaces are ideally hyperbolic, but for small movements of the tube T may be tangents to the average point of said ideal hyperola.

[Also in Group XVII] A web 8, Figs. 2, 4 and 11, is led from a supply roll 40 over a tensioning roller 51, carried by a pivoted arm 50 operating a brake 42 acting on a drum on the roll spindle 34, and then between a guide plate 54 and a spring-loaded pressure plate 55 pivoted at 56 to an H-shaped carrier 59 bolted to the machine casing. The plate 55 carries a swivel mounting for a pair of idler rollers 64 which co-operate with gapped rollers 74 mounted on a main cam shaft 27 to effect an intermittent downward feed of the web, the plates 54, 55 being slotted to enable the rollers to contact each other. The pressure between the plates is relieved by the engagement of the peripheries of the rollers 74 with the rollers 64, but at the end of each feeding movement the web is clamped between the plates, this action being assisted by a dimple 109 formed on the plate 54. The leading end portion 77 of each roller 74 is of spiral form so that the length of web fed may be varied by adjustment of the position of the. guide plate 54, this being effected by an eccentric cam rotatable by a knob 81. The cam shaft 27 is driven through a fibre gear 29 and overload clutch 84, 85. After a length of web has been fed it is severed from the supply to form a wrapper by a movable guillotine blade 94.
