Patent GB-868723-A (GB)
Title: A spring device
Inventor: DOETSCH HANS-PETER
IPC: F16F9/06
Filed: 1958-08-25
Abstract: 868,723. Hydro-pneumatic springs; adjusting body height. DOETSCH, H. P. Aug. 25, 1958, No. 27182/58. Classes 108(2) and 108(3). In a constant height spring suspension unit, a chamber 2 contains compressed air, gas, or any other type of spring, and chambers 4, 23 and 8 are completely filled with hydraulic liquid whilst chamber, 20 is partly filled with hydraulic liquid. In operation, if an impact is imparted to a piston 9, the piston 9 enters a cylinder 6 and liquid in the chamber 23 flows through a non-return valve 12 into the piston chamber 8. Liquid is also forced through a control pipe 5 into the chamber 4. At the same time fluid also passes through bores 13, 14, 15 and 16 into the control pipe 5 and thus into the chamber 4. Consequently the gas or spring in chamber 2 is compressed. Outward movement of the piston 9 takes place under the action of the compressed gas or spring in chamber 2. These movements are damped by the hydraulic liquid. As the piston moves outwards the non-return valve 12 is closed. This causes liquid to be sucked from the supply chamber 20, through a pipe 19 and a non-return valve 18, so that the total volume of the liquid in the chambers 4, 23 and 8 is increased. If, as the piston 9, moves outwardly the loading is normal, the piston will move completely out. Thus, through an aperture 21 and/or the longitudinal groove 22 a connection is made between the supply chamber 20 and the piston cavity 8 on the one hand, or the cylinder cavity 23 and the supply chamber 20 on the other hand, and liquid previously pumped in is forced into the supply chamber again. If, however, the loading is increased, the piston 9 will not move completely outwards, and a connection between chambers 4, 23 and 8 and the chamber 20 will not be made. The extra liquid which was drawn out of the chamber 20 will remain in the working cycle. The compressed gas or spring in chamber 2 will therefore be under greater pressure. Thus, after a few strokes of the piston 9 an increased pressure in the spring medium offsets the increased loading. If the loading on the spring is now reduced, the piston 9 will move completely out with the result that an equalisation of volume of liquid takes place again through the apertures 22 and 21. A radial bore 14 in pipe 5 ensures that liquid is only pumped in from the supply chamber 20 in the upper stroke range of the piston 9. A radial bore 13 allows transfer of hydraulic liquid during slow movements of the piston 9, wnen movement through the non-return valve 18 is not occurring. A spring 25, prevents the piston 9 being pushed fully into cylinder 6 and lield there due to an overload. The liquid in the supply chamber 20 may be under pressure.

Title: Digital display
IPC: G09G1/10
Filed: 1965-06-28
Abstract: 1,059,805. Displaying characters on a cathoderay tube. GENERAL PRECISION Inc. June 28, 1965 [July 23, 1964], No. 27257/65. Heading G4H. Each output from a logic circuit 50 (Fig. 3) representing an alpha-numeric character for display on a cathode-ray tube is connected to selected gates (400-424) in each of six identical logic circuits (one of which is illustrated in Fig. 6, not shown), the horizontal and vertical coordinates of each point of a grid on the cathoderay tube being each represented in binary code by three of the logic circuits. If, for example, the output corresponds to the letter " J " (Fig. 2, not shown), the beam is required.to commence its stroke at the point (0,2) on the screen and consequently the output is connected to the gate (400) of only the logic circuit corresponding to the vertical co-ordinate 2. When a clock pulse P, is fed to AND gate (430, Fig. 6, not shown) a signal is passed through gate (V2, Fig. 4, not shown) and a binary weighted resistance (R 2 ) to the " Y " deflection plate of the cathode-ray tube. The output is also connected to gate (402) of the logic circuit corresponding to a vertical co-ordinate 1 so that on the next clock pulse a signal is passed through gate (V1) and resistance (R1) to the "Y" " plate. When the whole character has been traced out in this way a reset mechanism (Fig. 7, not shown) restarts the count. Extra horizontal deflection for characters of large width, e.g. M or W, is obtained by using a gate (HO) and resistance (RO, Fig. 4, not shown) to pass a signal to the horizontal deflection plate 56. Horizontal and vertical counters 68, 78 (Fig. 3) are included to control the character position on the screen.

Filed: 1955-09-27
Abstract: 827,850. Control of motors; controllers. ENGLISH ELECTRIC CO. Ltd. Sept. 25, 1956 [Sept. 27, 1955], No. 27467/55. Class 38 (3). The chain block wheel shaft 11 of a spinning- machine is driven in accordance with the ratchet wheel shaft of the builder motion and operates a slider 12a of a variable resistor 12 through a crank 10 and link 13. A cam 14 rotates with the shaft 11 and controls micro-switches 15, 16. At the commencement of spinning the switch 15 is closed and switch 16 opened, so that relay coil 18a is energized through resistor 17, the resistor 12, and a trimming resistor 20. The relay 18 picks up to energize a low-speed contactor 23, and spinning begins at a low speed of operation. As the cycle proceeds, the resistor 12 is increased until the relay 18 drops out to energize the highspeed contactor 24. This is followed by the opening of switch 15 but this does not immediately affect the high-speed operation of the machine. The value of resistor 12 is gradually increased to a maximum whereupon the motion. of the slider 12a is reversed and the resistance is reduced until the cam 14 allows the closure of switch 16 thereby completing a circuit for the relay coil 18a including a trimming resistor 21. At this stage, however, the total resistance in circuit is such that the relay 18 does not pull in. Further reduction of the resistor 12 causes the relay to operate and the remainder of the spinning cycle is completed at the low speed of operation. The moments in the spinning cycle, at which the speed-changes are made, are. determined by adjustment of the trimming resistors 20, 21, and these adjustments may be made whilst the machine is operating. In a modification, the sliding resistor 12 is replaced by a rotary resistor coupled directly to the shaft 11. The two operating speeds may be provided by a change-pole motor or by two separate motors.
