Title: Improvements in or relating to radio relay systems
IPC: H04H20/67
Filed: 1937-08-26
Abstract: 485,353. Wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 26, 1937, No. 23424. Convention date, Sept. 25, 1936. [Class 40 (v)] In a two-way radio re peater system in which one transmitter and two receivers are employed at each repeater station, and one transmitter and one receiver at each terminal station, a different modulating frequency band is used for transmission in each direction. The terminal station TS1 comprises a transmitter T1 and antenna A1 operating on a, wavelength #1, signal bearing modulation frequency F1 from a generator G1 being applied through the mixing circuit M1. The receiver TR1 coupled to antenna RA1 passes only modulation of frequency F2 (which is used for the reverse direction of transmission) through fitter P1 and the mixer M1 to a recorder or loudspeaker 1. The repeater station RS2 comprises a transmitter T2 operating on wavelength #2 and an antenna A2 directive towards antenna RA1 and an antenna RA3 on the next and similar repeater station RS3. Receivers R2 and RR2 with antenna, RA2, RRA2, are tuned respectively to the waves from A1 and A3 on repeater station RS3. Filters P2, PP2, pass the signal bearing modulation frequencies F1, F2 to the mixing circuit M2, which consists of a five winding transformer, from which they are modulated on to the new carrier A2. The mixing circuit has 'also connected to it a recorder 2 and a generator G2 capable of producing frequencies F1 or F2 or both for initiation of signals at the station for transmission in one or both directions. The system operates in both directions by virtue of the fact that all the antennµ which are directionally receptive from one direction are connected to receivers which pass only the correct modulation frequency for that direction, and interference is avoided.

Filed: 1929-08-01
Abstract: 333,382. Ungerer, K. F. Aug. 1, 1929. Cold-rolling ; straightening. - A sheet metal plate is straightened and, if necessary, rolled by passing it between an upper frame e and a lower frame b of rolls, the rolls being thin but supported by stationary top and bottom surfaces d<1>, a<1>, along which they roll as both frames are moved bodily from left to right by rack and pinion gearing, A driving shaft i transmits motion tc pinions i<1> which move the racks b' fixed on each side of the lower frame b, the end of which has a fork b<5> engaging an eccentric roll f<1> fixed on the upper fram e<1> so that frame e<1> with its rolls is dragged along also. The same motion also causes the rolls to be rotated by dragging pinions b<3> at their ends along a fixed rack g for the lower rolls and pinions e<3> and rack h for the upper rolls. The eccentric f can also be moved to vary the staggering of the upper and lower rolls or to bring them into direct register for rolling the metal. If the sheet requires to be stretched or thinned along an edge to take out buckling, the upper rollers are forced down harder on that side by tilting their backing yoke d through bondwheels m<2> coupled to duplicated worm gearing 1 for pressing that side down against spiral springs k. If the sheet requires to be stretched or thinned along the middle to take out budding the rolls are caused to bulge downwards by similarly altering the surface of their backing support, this surface consisting of a number of transverse wedge irons d<2> which are forced inwards horizontally in varying degrees by pressure exercised on their ends by blade springs q, Fig. 1, flexed to the required curvature by a hand wheel p<1>.

Title: Improvements in or relating to pneumatic relooping machines
IPC: D04B17/04
Filed: 1937-08-30
Abstract: 479,012. Machine for repairing knit ware. GOSTKOWSKI, B. H. Aug. 30, 1937, Nos. 23712 and 23713. Convention dates, Sept. 2, 1936 and Aug. 19, 1937. [Class 112] In a machine for relooping " ladders " in knit ware in which the needle is actuated by an air pump, means are provided to suck the needle-carrying piston to its retracted position when the machine is at rest, so that its first motion on restarting is a forward one. Means are also provided for varying the force and amplitude of the needle strokes. In the form shown in Fig. 1, the electric motor 1 works a small auxiliary pump 2 directly and a main pump 8 through a clutch 4, 5, engaged by an electromagnet 9. The electrical circuit is indicated in Fig. 5. The apparatus is connected to the electric supply by terminals 27 and switched on by the contacts 28. A foot-operated contact slides over a resistance 29. When the whole of the resistance is in circuit, the current is too weak to actuate the electromagnet 9, but works the motor 1 to drive the pump 2. In this position, the core of the magnet 9 is in its outermost position, under the action of the spring, so that the pipe 22 from the pump 2 is connected to the needle holder tube 16 by the duct 24, and the pipe 15 from the mixing pump, which is idle, is connected to the air by the duct 25. The small pump 2 then sucks the needle piston 58, Fig. 13, to its rearmost position. On sliding the contact to cut out the resistance 29 and engage the contact 30, the current can energize the electromagnet 9 to cause the core to be moved against the spring. This action engages the clutch members 4, 5 to put the main pump 8 into action, and connects the pipe 15 with the needle pipe 16, and puts pipe 22 into connection with the air by the duct 26. The pump 8 then imparts its impulses to' the needle piston 58 to actuate the. needle, the first impulse being a forward one. The pump 8 is emptied and filled at each stroke so that by attaching a regulatable air escape, 47, Fig. 10, or a cushioning piston 50, Fig. 11, to the pipe 15, the amplitude and force of the needle stroke may be varied. The needle holder 34 has a needle carrier 36, Fig. 13, with a piston 58 and buffering springs 59, 60 at each end of the cylinder. The springs extend-about one third of the way into the cylinder so that when the amplitude and force of the needle is reduced to a minimum for effectiveness, the piston can vibrate in the unoccupied third. The amplitude of the piston 17 of the . pump 8 is also variable by moving the pivot 20 of the connecting rod 7 towards or away from the centre of the driving disc 6 by means of the cranked arm 19, Fig. 2. An arrangement is also described in which the clutch mechanism is dispensed with. Another modification describes the actuation of the needle without the use of the auxiliary pump 2, the pump 8 being put into communication with an air reservoir by means of a non- return valve.
