Title: Gas-heated appliance
IPC: F23N5/20
Filed: 1979-08-01
Abstract: The appliance comprises a gas burner (12) for heating e.g. water in a heat exchanger (15), with the exhaust gases being force vented by a fan (17) driven by a motor (41) and the gas supply controlled by a signal representing heat demand by a solenoid value (11). A control circuit (Fig. 2, not shown) is provided comprising relays R1, R2 by which the split coils (42, 43) of the motor (41) can be switched into series connection or one (42) can be disconnected. The relays are operated by a threshold circuit (50) recessing the heat demand signal so that when the burner is operating at 2/3 rds its rated output, the fan speed is reduced thereby reducing exhaust (and thus air intake) to match the reduced operation of the burner. <IMAGE>

Patent GB-2030064-A (GB)
Title: Forging turbine blade tips
IPC: B21J9/08
Filed: 1979-09-03
Abstract: A worn titanium blade for a gas turbine engine has metal displaced at its aerofoil tip, so that the aerofoil can be dressed to restore it to length. The titanium is not amenable to cold forging, or to being entirely heated, a forge is therefore provided which has dies which contact only the immediate area containing the metal to be displaced. The dies are heatable so as to heat the said area by conduction and powered so as to apply suitable pressure in a way which brings about isothermal displacement of the titanium.
Patent GB-793983-A (GB)
IPC: H04W88/02
Abstract: 793,983. Radio signalling. GENERAL ELECTRIC CO. Dec. 30, 1955 [Jan. 26, 1955], No. 37452/55. Class 40 (5). In a radio communication system in which a particular one out of several radio receivers is rendered operative by transmitting two different calling tones in successive pulses, the receiver is only rendered receptive to the second of the two signals upon the cessation of the first. The output of the discriminator 4 of the receiver (an F.M. system is assumed) is connected to a frequency selective amplifier 9 tuned to the first tone frequency and also to a similar amplifier 10 tuned to the second tone frequency. Amplifier 10 is normally cut off by bias applied to the cathode of valve 64 from a potential divider 67. The grid of valve 64 is coupled to the anode of a normally conducting control valve 53. On receipt of the first tone signal, the output of amplifier 9 charges a capacitor 58 in the grid circuit of valve 53 which passes grid current. Upon the cessation of the first signal, the valve 53 is cut off by the charge on capacitor 58. This raises the grid voltage of valve 64 and so enables amplifier 10 to pass the second tone signal. The output of amplifier 10 is rectified to control a relay 14 and connect the loudspeaker 6 to the receiver. This remains connected for the duration of the message by unspecified means.

Title: Adsorbent material
IPC: A62B17/00
Filed: 1980-03-14
Abstract: A material for protection against chemicals and short-term heating effects is made up of an air-permeable flexible base or support layer for adsorber particles, more specially, porous ones, which are placed on support columns or hairs on at least one side of the support layer. In a process for making the material, the adhesive composition is put on to the base or support material at separate points or dots in a viscous form and then the adsorber grains are placed on top of the composition. Then, by the action of centrifugal force or otherwise, the adsorber grains are moved upwards, away from the support layer, pulling out hairs or columns of the adhesive composition, which are then changed into a solid condition.

Title: Flowline connector seal plate
IPC: F16L39/00
Filed: 1980-10-01
Abstract: A flangeless, disc-like seal plate is disclosed for insertion between opposing flowline hubs for sealingly connecting, blocking or rerouting fluid flow between various fluid carrying lines within said flowline hubs. For connecting flow lines, straight throughbores 70, 72 within the seal plate are provided with V-seals 90 in channels on said seal plate around the throughbores, as well as O-ring seals 170, 172 around said V-seals and another O-ring near the periphery of the disc itself.

For connecting hydraulic control lines, the seal plate is equipped with transverse channels interconnecting various throughbores but may also be provided with blind ports for totally blocking off certain control lines at the plate. Within said throughbores, fluid diverter plugs are inserted which are either equipped with protruding caps for opening up corresponding check valves housed within hub lines or flush plugs such that said check valves remain closed after clamp-up. Through this arrangement various lines may either be blocked, be fluidly connected, or have their fluid flow rerouted internally without rearranging the alignment between the lines within the flowline bundle. <IMAGE>
Patent GB-2062325-A (GB)
Title: Gaming and amusement machines
IPC: G01P13/04
Filed: 1980-10-09
Abstract: A fruit machine having means sensing the positions in which symbol carriers (R) stop can accommodate rotation of the carriers in either direction. Associated with each carrier, two photo-electric cells (P1, P2) are each arranged to receive pulses of light from a light source through one of two series of apertures (S) in a disc (D) which rotates with the carrier (R). The apertures are formed so that the cells (P1, P2) generate two trains of electrical pulses of the same frequency but out of synchronism. The pulses are fed as an activating signal to a counter which changes its state in step with rotation of the carrier. Since the trains are out of synchronism, the signal is asymmetrical in time so that reversal of the rotation of the carrier causes a different signal to be sent to the counter. The two signals cause adjustment of the counter by an increment and a decrement, respectively. <IMAGE>

Title: Through-feed cylindrical thread rolling dies
IPC: B21H3/04
Filed: 1980-11-19
Abstract: A generally cylindrical through- feed thread rolling die (11, 12) has a tapered lead-in portion (13), a cylindrical dwell portion (17), and a tapered exit portion (19). A uniform spacing exists between the crests (22) of the thread forms (23) throughout the length of the die. The spacing between the roots of the die is uniform except at the junctions (16, 18) between the dwell portion and the two tapered end portions, where a larger spacing exists between the roots of adjacent thread forms. Because the crest spacing on the thread forms of the die is uniformly maintained throughout the length of the die, excessive pressures do not exist at the junctions (16, 18) between the dwell portion and the two end tapers, and drunken threads on the workpiece (10) being rolled are virtually eliminated. <IMAGE>

Patent GB-2091196-A (GB)
Title: Apparatus for sequential displacement of a carrier
IPC: B65G47/90
Filed: 1981-01-17
Abstract: A carrier (2) is required to be moved through a series of set positions for various operations to be performed on a workpiece on the carrier. The carrier may be on or part of a rotatable arm (1) or guided on a track, and it is connected by a cable (8) to a fixed but adjustable point. It is also urged by biasing means such as a spring (11) towards a start position, which keeps the cable taut. The other set positions are determined by devices which alter the cable path between the carrier and the fixed point, creating or accentuating bends or bights in the cable, which thus pulls the carrier against the bias. These devices may be rams (17, 18, 22) or solenoids which move pulleys (13, 14) around which the cable is led. <IMAGE>
