Patent GB-898330-A (GB)
Title: A pneumatically-operated free piston engine
IPC: F01B17/02
Filed: 1958-10-01
Abstract: 898,330. Compressed air engines; engine valve gear. GEWERKSCHAFT EISENHUTTE WESTFALIA. Oct. 1, 1958 [Oct. 8, 1957], No. 31372/58. Classes 122 (2) and 122 (3). A pneumatically-operated free piston engine is arranged so that the working air is controlled by a freely-oscillating slide valve 34 which is guided in a bore within the piston 11 and disposed in the direction of oscillation of the latter the distribution of the working air taking place by way of duets provided in the interior of the piston. The piston is mounted in a cylinder 10 and is formed with a larger working piston 12 defining working chambers 14, 15 and two smaller pistons 16, 17 working in cushion chambers 18, 19. The slide valve 34 is mounted in an axial bore in the piston and is formed with an annular groove 35 which, depending upon the position of the valve, allows compressed air to flow to either of the working chambers 14, 15. In operation, with the valve in the position shown, air is fed through an inlet 20, annular chamber 21, ports 22, annular groove 23, ports 24 and annular chamber 25, into the working chamber 15, and air in the chamber 14 is exhausted through an axial bore 30, annular groove 32 and radial bores 33. The piston then moves and accelerates to a midway position until, at this point, air trapped in the cushion chamber 18 begins to retard its movement. The slide valve, due to its kinetic energy, continues to move at the same speed and thereby reverses its position, thus allowing the air to be admitted into the chamber 14; the valve is cushioned at each end of its stroke by rubber or like buffers 36. In order that the valve may be returned to the starting position shown irrespective of when the compressed air supply to the piston is shut off, an auxiliary differential piston 38 is mounted in a cylinder 40, 42 and is connected to the valve by a rod 46 and spring-release coupling 47, 49. At the commencement of a stroke with the valve in the position shown, air which is being fed to the chamber 15 is also fed to the larger end 39 of the auxiliary piston through a port 26 and restricted opening 43 thereby moving the auxiliary piston together with the valve until the latter reaches the end of its stroke; the stroke of the auxiliary piston is greater than the stroke of the valve and thus continues its movement until the spring-release coupling 47, 49 is disconnected. The valve is now free to move, during normal running, under the action of kinetic energy. When the air supply is discontinued, air which has been trapped between the inner side of the piston head 39 and the end of the cylinder 42 expands and moves the piston 38 until the spring-coupling re-engages with the valve and returns the latter to the position shown.

Title: Improvements in variable speed gears for cycles
IPC: B62M11/14
Filed: 1923-12-14
Abstract: 227,599. Solomon, M. Dec. 14, 1923. Variable-speed epicyclic gearing for cycle hubs yielding three speeds is controlled by ratchet pawls which are disengaged in succession by a shaped sleeve 15, Fig. I., as it slides progressively in one direction ever a solid or unslotted axle 1. In the configuration shown in Fig. I., pawls 10 carried by a sun gear 8 are operative to prevent that gear from turning forward. Pawls 9 for the middle gear pass idly over ratchet teeth 11<a> upon the driving planet carrier 5, and the lowgear ratchet 3a also overruns. Planet gears 6 roll round on the anchored gear 8 driving an internally-toothed ring 7 and hub 19 at highest speed. The sleeve 15 on moving a step to the left engages tails 10<a> of the pawls 10 disengaging these pawls. The pawls 9 at once engage so that the gearing turns solid on middle speed. There is no "free" position between the speeds, and the vehicle can be wheeled backwards on all speeds. The planet gears 6 intermesh with other planet gears 4, Fig. II., by which they are connected to a second sun gear 3. On further movement of the sleeve 15 to the left, the tails 9a of the pawls 9 are raised, upon which the ratchet 3a becomes operative to prevent the gear 3 from turning backward. The intermeshing planets operate to drive the ring 7 at lowest speed. The axial movement of the sleeve 15 is effected by a pin 15b engaging a screwed slot in a sleeve 16, which is adapted to be turned about the axle 1 by a lever 16<a>. The lever 16<a> is adapted to be operated against the action of a spring 21 through a cord or toggle arranged so as to be affected to an infinitesimal extent by adjustment of the hub in the rear forks of the vehicle. The invention is described in combination with a back-pedalling brake to which parts 12, 17, 22 belong.

Abstract: 1,127,283. Selective voltmeter systems. SOLARTRON ELECTRONIC GROUP Ltd. 13 July, 1967 [15 July, 1966], No. 31954/66. Heading G4H. A central digital meter is connected to a plurality of slave units each having input terminals, a digital indicator and control circuits responsive to control signals from a selector unit to couple the input terminals and indicators of the several slave units in turn to the central meter which measures the signal at the input terminals connected to it and transmits digital data to the indicator to display the magnitude of the signal. The central meter 6 is connected to the several slave stations by a group of ten wires 1. The input signal from the slave station is applied at terminals 3 and switched by relay contacts 4 to the input lines 2 of the central voltmeter. These pass the signal through an attenuator 5 controlled via a logic circuit 7 from a range selector 8 at the slave station. This is connected when the slave station is selected by energization of relay 10. This is done by selector 11 at the central station which sends a number of pulses to counter 13 at the slave station. If the appropriate number is sent, logic circuit 14 responds and gives a signal to operate relay 10 and to enable gates 15. Each slave station responds to a different count. The input from the slave station is now applied to the central voltmeter through the attenuator which is switched to give an appropriate reduction. The output of the voltmeter is four decimal digits each presented in binary form on four leads. The digits are applied in turn on four leads to a decoder 20 at the slave station, and the appropriate value is displayed on a multicathode tube, the four tubes being selected in turn by signals through corresponding ones of gates 15 from counter 18. This is stepped by pulses from the central station. Instead of serial-parallel transmission, pure serial transmission may be used.
