Title: Improvements in steam motor-driven locomotives provided with air-cooled condensers
IPC: F01K15/02
Filed: 1922-05-15
Abstract: 194,980. Aktiebolaget Ljungstr÷ms Angturbin. March 24, 1922, [Convention date], Addition to 193,366. Cooling condensers, air blast for.-The auxiliary motor described in the parent Specification for driving the condenser fans, is formed as a steam turbine and geared to the fans through doublereduction toothed gear. The auxiliary turbine 6, Fig. 1, drives an intermediate shaft 19 which in turn drives the sleeve 22 connected to the common fan shaft 24 by a diaphragm coupling 25. In this construction the turbine shaft is mounted to overhang its bearings 10, 11 and is counterbalanced by a weight 12. The turbine shaft may be connected to the first pinion 13 by means of a resilient shaft 16 and diaphragms as described in Specification 149,693, [Class 80 (i), Gearing, Belt &c.]. The outlet of the turbine is connected resiliently to the pipe 7 to allow for unequal expansion. Fig. 2 shows an arrangement in which the auxiliary turbine is supported by its outlet pipe 7 from the steam-distributing pipe 2. The gearing of the auxiliary turbine is continued beyond the shaft 24 through the casing 26 to the main turbine, so that the latter can be used to drive the fans when running on a down grade, and the auxiliary turbine may be used to supplement the main turbine in emergency. Disconnecting devices controlling these movements are operable from the driver's cab. A construction is illustrated in which the relative movement of the members of a roller friction clutch causes the main turbine to take up the drive of the fans when it reaches a definite speed.

Title: Improvements in or relating to insoles for boots and shoes and to the method of preparing the same
IPC: A43B13/39
Filed: 1924-06-06
Abstract: 230,683. Crick, W., and Tilson, J. E. June 6, 1924. Connecting uppers to insoles. - A felt insole 1 is channelled at 2 round its marginal edge and split so as to form two lips 4, 5. There is then applied to the upper face of the two lips and the centre part 9 of the insole a thick coat of rubber solution uniting the lips and rendering the centre part waterproof. A hardening solution such as glue, gum, or starch solution, or paraffin wax is applied to the feather 7, lip 5, and toe 8 leaving the centre part of the insole unseated. A strengthening or toughening fluid such as rubber latex or a thin rubber solution in trichlorethylene is used on the channel 2 and lip 4. The heel may be toughened or left in a natural condition as is the surface of the insole near the foot. The hardening prevents buckling of the insole when placed in a machine and also assists lasting. The toughening enables the insole to withstand strain during welting. Rubber latex or a thin solution of rubber is preferably used for toughening as it penetrates the felt while waterproofing is done with a thick rubber solution in naphtha. Merino wool felt is preferably used, but if poor quality felt is used it is gemmed after treatment. The lips 4, 5 may have a rubber insert 6 or a single lip may be used. The rubber latex may be mixed with vulcanizing agents and the insole may be vulcanized.
Patent GB-601128-A (GB)
Title: Improvements in or relating to arrangements for demodulating duration modulated pulses
IPC: H04B14/02
Filed: 1945-06-01
Abstract: 601,128. Pulse modulation. STANDARD TELEPHONES & CABLES, Ltd. June 1, 1945, No. 13867. Convention date, July 29, 1944. [Class 40 (v)] Duration-modulated pulses are demodulated by translation into amplitude-modulated undulations produced by the shock excitation of a tuned circuit. The duration-modulated pulses 21, Fig. 1, are applied to the grid of a limit clipping valve 2, the anode circuit of which includes a resistance 3 and a resonant circuit 7. The anode of valve 2 is also connected to the grid of a damping valve 5 connected across circuit 7 and, through a condenser to the grid of a threshold clipping amplifier valve 13, feeding a low-pass filter 17 and signal reproducer 18. The natural period of the resonant circuit 7 may be twice the maximum pulse duration. When a pulse of this duration is received, the negative-going leading edge 23, Fig. 2d, at the anode of valve 2 shock-excites circuit 7 to produce the negative half-sine wave 23, Fig. 2e, the damping valve 5 being blocked at its grid for the duration of the incoming pulse. During the next half-wave in circuit 7, the natural damping of the circuit reduces the amplitude to 25, but the positive-going trailing edge 26 of the received pulse produces a component 24a and hence a resultant undulation 25a. During this undulation valve 5 is non- conducting as its cathode is sent positive relative to the anode. No further undulations occur as the next natural oscillation is damped out by valve 5 which is now conducting. Pulses of smaller widths produce undulations of the same duration, but of smaller amplitudes proportional to the pulse widths, Fig. 2f, which are clipped at level 33 by valve 13. The signal is recovered from the amplitude-modulated undulations by passage through filter 17. Alternatively, for pulses with small width variation, the resonant circuit is tuned to a harmonic of the frequency discussed above, the period of which is comparable with the period of the maximum change in pulse width. The circuit behaves in a similar manner, but several free oscillations 28, Fig. 2h, occur in circuit 7 before the trailing edge 29, 30, &c., Fig. 2g, of the . incoming pulse, produces the final amplitudemodulated undulation 31, 32, &c. Specification 592,789 is referred to.
