Title: Method and Control System for Adjusting a Pit Prop Axis
IPC: E21D23/00
Filed: 1967-02-13
Abstract: 1,167,614. Advancing mine roof support control circuits. BERGWERKSVERBAND G.m.b.H. 13 Feb., 1967 [17. Feb., 1966: 16 April, 1966], No. 6681/67. Heading E1 P [Also in Division G3] A pit prop is provided with a control system operable to adjust the angular position thereof in relation to the vertical, the system comprising means for sensing the inclination of the prop from a predetermined angular setting in relation to the vertical to provide signals to control means for causing operation of at least one ram for adjusting the angular position. The angular position of the prop may be adjusted in a single plane by a single ram or in two perpendicular planes by two separately controlled rams. The ram or rams may act at the top or bottom of the prop. As shown, the sensing means is in the form of a pendulum 136, Fig. 3 (not shown) controlling the opening and closing of two valve ports 134, 135, but in alternative embodiments the sensing means is in the form of electrical contacts which co-operate with the prop itself or a pendulum thereon to provide the control signals. Assuming the port 134 is closed by the pendulum 136 due to an undesirable tilting of the prop, compressed air from a line 130 enters the other port 135 by way of a reducing valve 131 and a branch conduit 102. Air entering the port 135 flows to a line 105 and causes opening of a diaphragm operated valve 106 which thus directs air from a line 130b to cause a valve 108 to open. The opening of the valve 108 supplies hydraulic fluid through lines 150, 153 to the chamber 107b of a ram 121 and causes the piston rod 123 thereof to move the prop to its correct angular position. Hydraulic fluid in the other ram chamber 107a flows to a reservair 151 through a second valve 108. Tilting of the prop in the opposite direction opens port 134 to effect reverse operation of the ram.

Title: Improvements in hydraulic presses for treating flat stock materials
IPC: B29C43/00
Filed: 1960-02-26
Abstract: 869,292. Hydraulic presses. UNITED STATES RUBBER CO. Feb. 26, 1960 [April 2, 1959], No. 6776/60. Class 69 (2). [Also in Group VIII] An hydraulic press comprises a ram-cap 20 arranged for movement towards and away from a stationary cross-head 17, and a platen 31 hinged at one end to the ram-cap and having means 37 . . . 40 for limiting its angular movement away from the jam-cap. The ram-cap 20 is vertically movable by rams 19 and is provided with hinges 29 for the platen 31, the free end of which can be urged upwardly by piston-andcylinder devices 46, springs, cams, or rack-andpinion mechanisms, to an angle limited by links 37...40 or bolts between the ram-cap and platen. A platen 52 is hinged at one end 50 to the cross-head 17 and links 57... 59 or bolts determine the maximum angle which it can make with the crosshead. Another platen 65 is suspended by rods 76 to a position intermediate the platens 31, 52 and can be urged to this position by piston-and-cylinder devices 72, the rods 76 and brackets 67 on tie-rods 15 serving to maintain the movement of the platen 65 parallel to that of the ram-cap 20. The platens may be heated or cooled by steam or other fluid passing through passages 32, 64, 66 or by electrical means, and insulating means may be provided on the crosshead and ram-cap. In operation, sheet material 78, 79, Fig. 3, such as belts, matting, or tiles either of laminated or . single ply construction and consisting of plastic, non-plastic, natural or synthetic rubber or fabric which is to be cured, vulcanized, heat or pressure treated, is laid on the platens 31, 65 which initially are in the position shown in Fig. 3. Pressure fluid is supplied simultaneously to the rams 19 and devices 46 to tilt the platen 31 to its upper position as determined by the links 37, 40 and move the ram-cap 20 and platen 31 upwardly until the right-hand end of the platen 31 engages the platen 65. Further upward movement of the ram-cap moves the platen 31 to a horizontal position against the pressure in the devices 48 and the sheet 79 is pressed evenly between the platens ; the angular movement of platen 31 prevents air being trapped between the material and platens. Continued upward movement of the ram-cap presses the sheet 78 against the platen 52 first by one edge and then evenly, the force of the rams 19 being sufficient to overcome the force in the devices 72. After a predetermined time to permit the sheets to be treated, the rams 19 are connected to exhaust and this ram-cap is retracted by piston-and-cylinder devices 25, the platens separating first at the hinged ends. The supply of pressure fluid to the various piston- and cylinder devices may be controlled automatically and in synchronism with the feeding of the material when in belt or strip form into the press. Protector flaps may be provided to prevent the entry of dust between the platens and the crosshead and ram-cap.

Title: Improvements in and connected with installations for electrically lighting, heating and ventilating railway carriages and other vehicles
IPC: H02J7/22
Filed: 1919-03-19
Abstract: 145,120. Rohman, H. D. March 19, 1919. Systems of charging and discharging galvanic batteries.-An electric supply system for lighting, heating, and ventilating railway and other vehicles comprises a constant-watt dynamo A, for example one driven by a slipping belt, a battery B, and an automatic battery-charge-rate reducing means E controlled by a shunt coil and also charge-stopping means F controlled by the chargereducing means. The generator is safeguarded on open circuit and on overload, the normal condition of the apparatus being restored each time the train stops. The usual automatic cut-in switch D short circuits an iron wire resistance 3 in series with the lamp circuit when the generator is out of action. The rate of charge is reduced when the battery reaches a given voltage, for example by switching a resistance 13 in parallel with the dynamo: a shunt coil 8, connected between the negative pole of the dynamo by leads 2, 10 and the positive pole by leads 9, 14, effects this and is calibrated to operate upon a predetermined voltage. The same action occurs if the battery be out of circuit, thus protecting the dynamo against open circuit running. A series coil 7 carrying the battery charge current co-operates with the shunt coil 8 to protect the battery against excessive charging currents; proper calibration of the two coils ensures that the critical condition at which the charge must be reduced will always be correctly met. When the voltage of the battery has risen to a point corresponding to full charge the relay F becomes operative to stop the charge by largely increasing the resistance of the dynamo field circuit. The coil 16 of this relay is in shunt with the generator through wires 14, 9, coil 16, wire 18, resistance 19, wires 10 and 2. After the switch E has operated the resistance 19 is short-circuited by the contact 12 and the coil 16 becomes fully responsive to the generator voltage. At the critical pressure the resistance 23 and coil 17 are placed in series with the dynamo field circuit by the severance of the shunt path through the member F and contact 20. The coil 17 assists the coil 16 to hold the switch F open until the train stops, and prevents any hunting. The action of the switch F also protects the generator against open circuit running, as it will open to reduce the excitation of the dynamo if a predetermined voltage be exceeded, all shunt coils, resistances, and lamps being also protected against excess voltage. The battery may be of the double unit type. Any method of reducing the rate of charge may be adopted, e.g. series-parallel control of field coils or sections thereof, additional series coils on the generator, loading the generating by an electric brake, or by resistance in series in the generator circuit. A variable air gap may be employed in the reducer switch E to vary the charging rate permitted.
