Title: Improvements in or relating to electrically-maintained vibrating forks
IPC: H04L13/04
Filed: 1924-09-17
Abstract: 245,051. Western Electric Co., Ltd., (Western Electric Co., Inc.). Sept. 17, 1924. Synchronous movements.-The rate of vibration of an electrically maintained fork, particularly intended for use in synchronizing telegraph apparatus, is controlled by magnetic means comprising a pair of pole-pieces in alignment with and close to the free ends of the tines of the fork. In the apparatus shown in Fig. 1, the ends of the tines 9 vibrate in the field of an electromagnet 15 of which the pole faces 16, arranged as shown, have the same dimensions as the ends of the tines. The current flowing through the magnet coil 15 can be varied by means of a variable resistance 18, and thus, by adjustment of the magnetic field around the ends of the fork, the rate of vibration can be controlled. The frequency is preferably indicated by a suitably calibrated device 19. An electromagnet 7 maintains the fork in vibration, being included in the usual manner in the circuit of a battery 6, together with an automatic make- and-break contact 8. A Lacour motor 13, 14, driven by impulses supplied through the fork in the usual way, is included in the apparatus shown. Fig. 2 shows a modification as used in the synchronizing system described in Specification 244,814. In this arrangement, the frequency-controlling magnet has two windings 40, 42. The current in the winding 42 can be varied by manual control, as in the apparatus above-described, while the coil 40 is included in the plate circuit of a thermionic amplifier 22, the current in which depends upon the grid potential. This is under the control of current impulses received from a telegraph line or cable.

Title: Improvements in the manufacture and production of olefines from gaseous hydrocarbons
IPC: C07C4/02
Filed: 1934-10-15
Abstract: Olefines are produced by heating gaseous paraffins in admixture with preferably 10--45 per cent of oxygen to 750--1000 DEG  C. under considerably reduced pressure such as 0,05--0,5 atmospheres. The hydrocarbon may contain other gases such as nitrogen or hydrogen and gases containing or supplying oxygen may be used instead of oxygen, for instance, nitrogen peroxide may be used. Steam may be present. Catalysts are unnecessary, but the reaction chamber may be provided with filling-material.  In examples, butane and oxygen are led through a clay tube filled with pieces of quartz at 920 DEG  C. and at pressures of 230 and 200 mm. respectively, and propane and oxygen are similarly treated at 860 DEG  C. and 200 mm. pressure.

Title: Improvements in hydraulic shock absorbers
IPC: F16F9/14
Filed: 1933-10-25
Abstract: 415,605. Hydraulic shock-absorbers. ELLIOTT, C. K., 38, Kambala Road, Bellevue Hill, New South Wales, Australia. Oct. 25, 1933, No. 29598. [Class 108 (iii).] In an hydraulic shock-absorber comprising a compression chamber communicating with a relief chamber or reservoir through an elongated relief port or series of ports, and a spring- pressed control piston slidably mounted in a cylinder and subjected, through a byepass, to the compression-chamber pressure, when this pressure is sufficient the piston is moved against its spring-pressure to obstruct progressively the relief port or ports. In the singleacting rotary-vane shock-absorber shown in Figs. 2, 3 having fixed radial abutments 8, clockwise rotation of the vanes 10, Fig. 2, fixed to a hollow spindle 9, forces liquid from the chambers 12, 12<1> to the chambers 13, 13', in each case through a side-passage 21 and a series of apertures 23 in the spindle into the bore 15<1> of the spindle and thence through a slot 24 and passage 25. When the pressure is sufficient liquid also passes through a passage 22 into a space 15 in the spindle behind a spring- pressed piston-valve 17 and forces it to restrict the apertures 23 progressively with the rise in pressure thus stiffening the shock-absorber. The return movement of the vanes is unrestricted. Adjustable tail-pins 18, 20 limit the movements of the valve 17. In a double-acting rotary-vane shock-absorber two connected, spaced-apart, slide valves 17 are spring-pressed so as to be normally with their leading edges adjacent opposite sides of the apertures 23, rotation of the vanes in either direction causing movement of the valves so that the appropriate one restricts the apertures 23. Fig. 6 shows a single - acting reciprocating - plunger shock - absorber wherein slight movement of the plunger 34 due to rotation of the arm 33 forces liquid through an elongated port 41 in the cylinder 35, apertures 39 in the valve-chamber 38 and thence through apertures 43<1> to the relief chamber 37. Increased pressure forces liquid also through an aperture 40 into the valve-chamber so as to move the valve 44, against spring-pressure and any fluid backpressure in front of the valve, to restrict the apertures 39 thus stiffening the shock-absorber. A double-acting reciprocating plunger is also described having connected slide-valves similar to those described in connection with the double-acting rotary vane shock-absorber.
