Title: Improvements in combination steaming and pressing iron
IPC: D06F75/16
Filed: 1944-09-26
Abstract: 585,234. Hand-irons. DEHN, F. B. (Silex Co.). Sept. 26, 1944, No. 18378. [Class 138 (ii)] In a steaming iron having a two-way valve-15 by which the steam can be switched from the sole-plate ports 19 to an exhaust port 16 when dry ironing, steam which condenses in the exhaust port is directed to a reservoir 32 so as not to be carried by the steam jet over the work. As shown, the outer end of the port is closed by a disc 28 inwardly flanged at 30 round an outlet opening. Condensed steam collects round the flange and drains through a hole 31 in the disc to the reservoir 32, where it is re-evaporated by the heat of the iron, the reservoir being a recess in the body casting 6. An integral partition 20 divides the body into a water space 7 and a steam space 8 to which the steam passes through openings 21 in the partition. A baffle 26 spanning the openings prevents water entering the steam space.

IPC: B28B11/08
Filed: 1916-12-30
Abstract: 105,052. Scrivener, E. D. M., and Cooper, P. Dec. 30, 1916. Pressing plungers and dies; casting and moulding screw-threads.-In moulding porcelain or earthenware articles, such as insulators, two concentric members 8, 9 remain pressed against the ends of the article by springs 17, while the plungers, consisting of annular Darts 5, 6, are being withdrawn. The two concentric annular parts 5, 6 are carried by a member 4 connected by three vertical rods 3 to the head 1. The stems of members 8, 9 pass through the member 4 and are carried by a plate 12 screwed into a ring 14, which is rotated to compress the springs 17 before each stroke of the plunger. To withdraw the plunger, the ring 14 is partly unscrewed so that the collar 16 is raised above the head 1. and the plunger is lifted in the usual manner. The springs 17 hold the members 8, 9 in contact with the edges of the article until the member 4 strikes the plate 12, whereupon the withdrawal of the members 8, 9 commences. To provide a screwed recess in the article, a screw tap 19, held in position by a spring plunger 20, is used. When the press plunger is withdrawn, the tap 19 becomes disengaged from the plunger 20 and is subsequently unscrewed by hand or by mechanical means. For compressing the springs 17, the plate 12 may be replaced by a cam, lever, &c.

Patent GB-421786-A (GB)
Title: Improvements in superheterodyne receiving sets
IPC: H03G3/22
Filed: 1934-06-25
Abstract: 421,786. Valve circuits for wireless reception. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. June 25, 1934, No. 18732. Convention date, Aug. 3, 1933. [Class 40 (v)] Automatic volume control in a super-heterodyne receiver is obtained by varying the anode voltage of the local oscillator inversely to the variation in the amplitude of the received signal. This results in a variation of the amplitude of the local oscillations to maintain the amplitude of the intermediate frequency constant. A high-frequency amplifier HV is followed by a first detector D1 which receives local oscillations from a back coupled valve 12. The intermediate frequency oscillations are amplified at MV and detected by the diode section of the diode-triode D2. The rectified output across resistance 7 is fed to the grid of the triode section of the valve D2 for amplification and is also applied to the grid of a valve 19 through a low-frequency suppressing filter F. The anode current of valve 19 thus varies in accordance with the amplitude of the intermediate frequency oscillations, and since it is in parallel with the oscillator 12, the anode voltage of the oscillator varies inversely to the variations of the intermediate frequency. The bias of the amplifiers HV and MV may also be controlled by the potential across the resistance 7. According to the Specification as open to inspection under Sect. 91 the high-frequency oscillations may be rectified and applied to the grid or anode of the local oscillator, or the rectified intermediate frequency oscillations may be applied to the grid of the local oscillator. This subject-matter does not appear in the Specification as accepted.

Apparatus for assembling a split spring- retaining ring R in a groove 16 of a shaft or the like 15, such as for retaining a member 17 thereon, comprises means 13 for holding the shaft vertically, a mandrel 18 adapted to receive a ring and having a cylindrical body 18b and a frusto-conical lower end 18c, means 19, 20 for normally holding the mandrel spaced from but vertically aligned with the shaft, and a reciproeatory hollow plunger 34 adapted to be lowered over the mandrelto open the mandrel holding means 19, 20 and lower the mandrel on to thei shaft and, also to push the ring along the mandrel and expand it over the conical end 18c and into the groove 16. The rings are held in a vibrating hopper 12 from which they fall by gravity along a shoot 38 and are released individually on each stroke of the plunger by a finger 41 to drop through a hole 38 and over the nose 18a of the mandrel. The mandrel holding levers 19, 20 which are pivoted at 27, 28 and biased upwardly by springs 21, 22, engage in opposite longitudinal slots 25a, 26a of the mandrel. The plunger 34 has a resilient frustoconical end 34a with four longitudinal slots 36, 36a, 36b. Downward movement of the plunger causes its resilient lower end to engage a ring on the mandrel, and open the levers 19, 20, Fig. 2 (not shown). Spring-loaded blades 54, 55 engaging in the mandrel grooves 25a, 26a, prevent the mandrel from sticking to the plunger on its upstroke. The plunger is operated by a double-acting compressed air motor 30, 32 whose central valve is operated automatically by a solenoid controlled by a switch. Fig. 5 (not shown) actuated by a slide 60, carrying the shaft fixture 13, when it is moved by a hand or foot lever into position beneath the mandrel.

Abstract: 825,720. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. June 4, 1958 [June 14, 1957], No. 18783/57. Class 40 (4). Stations located in coal mines and connected to an automatic exchange are enabled to call an attendant in the event of an emergency by means of keys connected between an additional common wire and one of the normal line wires. A partyline serving a number of magneto stations is shown connected through a coupling unit MTCU, as disclosed in Specification 515,805, for preventing the transmission of unsafe voltages, to a partyline relay set PLRS, calls to the exchange being made by a prolonged burst of ringing current to bring about the operation of relay SW (not shown). In the case of individual lines the set PLRS would be omitted. Except brief periods while relay contacts change over wire L1 is connected to positive potential whether the line is idle or busy, and thus provides a signalling circuit in conjunction with common wire D by means of keys such as PBA. When a key is operated, relay PX responds and relays PY, PZA energize for a period of about 75 milliseconds during which the short-circuit is removed from relay EC of each underground line. Relay EC of the calling line pulls up, locks, lights lamp LP1 and closes an alarm circuit. The attendant plugs into jack JKA and thus directs the calling line from the exchange to his set. A priority call may be made to any line by plugging in and throwing key KR to permit ringing of bells such as PCBA connected between common wire C and wire L2.

Title: Improved circulating fuel nuclear reactor
IPC: G21C1/24
Filed: 1962-05-15
Abstract: 948,115. Nuclear reactors. UNITED STATES ATOMIC ENERGY COMMISSION. May 15,1962 [May 17, 1961], No. 18609/62. Heading G6C. In a circulating fuel nuclear reactor having at least one cylindrical fluid fuel channel passing through the core, means are provided at the entrance to each fuel channel for imparting a tangential velocity component to the fluid fuel passing through it so as to modify the axial velocity profile of the fuel, and orifice means are disposed at the exit of each channel to provide an axial flow pattern similar to that created at the entrance to preserve the established velocity relationship generated in the fuel. The reactor shown in Fig. 1 comprises a moderator 21 provided with a number of channels 22 through which fuel is circulated by means of a pump 29. A vane element 27 is disposed between the pump and the inlet to each channel to impart a tangential velocity to the fuel. By suitable design of the angle of the vanes it is possible to match the velocity distribution to the volume heat distribution so that the radial temperature distribution in the fuel is approximately constant; by over compensating, the fuel can be made to cool the walls of the channel. At the upper end of each channel is an exit orifice element 26 perforated with a distribution and size of perforation providing an axial flow pattern similar to that which exists in the fuel channel. As an alternative the element 26 may be replaced by a vane element similar to element 27. After passing through element 26 the fuel flows through tubes 37 back to the pump inlet, the tube 37 forming a heat exchanger with a surrounding conduit 41 through which a secondary coolant flows. Removal of fission gas may be effected by providing a fube 44 connecting with a central orifice 46 in an exit element 26 and leading through a heat exchanger to an expansion chamber 47, from which fission products and/or purging gases are withdrawn through vent 48 whilst entrained fuel is returned through vent 49 to a header 39.

In a connection between two wires or cables, such as a wire 1 and a lead-in wire 3 of a capless lamp 4, the wire 1 is secured in one end of a sleeve 2 having a flattened portion with a hole 5 therein through which the wire 3 is threaded or bent into contact with the sleeve. The assembly is then drawn into an aperture 7 in a supporting body 6 of, for example, ceramic or hard rubber, so that the walls of the aperture press together the wire 3 and the sleeve. Alternatively, the sleeve 2 may be omitted, the end of wire 1 in this case being flattened and provided with a hole. In the case of a stranded cable, the strands are first soldered or welded together. More than one connection may be accommodated in the body 6 as shown in Fig. 5. The mouths of apertures 7 are formed with lips 9 past which the connections are forced so that the lips retain them in the body 6 which in this case is necessarily of semi-flexible material.

Title: Method and devices for the systematic study of the suspension of vehicles
IPC: G01M17/04
Filed: 1953-07-07
Abstract: 745,561. Testing road vehicle suspensions. FEDERSPIEL, J. M. July 7, 1953 [July 25, 1952], No. 18849/53. Class 108 (2). [Also in Groups XIX and XXIV] A method of studying the working characteristics of a suspension system of a vehicle consists in transmitting to at least one of the wheels of the vehicle a substantially vertical oscillating movement having a sinusoidal function of the time, of known amplitude and frequency, in sensing the movement transmitted by the suspension to various points on the vehicle, and in comparing the transmitted movements and the incident movement, preferably after they have been recorded. In Fig. 2 reciprocating movement by a member f is transmitted to a vehicle wheel e. This movement and the movements transmitted to the axle i, body j and dummy k are all recorded on a drum n through levers g1, g2, g3 and g4 respectively. A timebase curve is traced by a tuning fork p. By comparing the curves obtained at a given frequency of vibration, the qualities of the suspension for that frequency may be analysed. In a test bed arrangement, Fig. 14, cams G2 and G4 are used to oscillate the vehicle wheels. The inner face of each cam is circular in crosssection whilst the outer face conforms to any desired configuration, for example the curve H in Fig. 5. The cross section of each cam is a smooth transition between the two profiles. Each cam is movable by toggle means 19 along a rotatable splined shaft 16 so that the amplitude of oscillation transmitted by each cam to its tyre can be adjusted by displacing the cam along its shaft. As shown in Fig. 14, the cams are positioned to give maximum amplitude of displacement. Associated with each cam is a differential controlled by a hand wheel 32 for adjusting the relative phase relationships between the cams. The -cams under the rear wheels of the car may be rotated by the car itself, the cams under the front wheels being geared to those under the rear wheels.
