Filed: 1937-01-22
Abstract: 470,127. Photographic contact-printing and developing apparatus. KUNSTADTER, V. Jan. 22, 1937, No. 13774. [Class 98 (ii)] In a combined contact-printing and developing apparatus, an endless belt carries the sensitive paper which is gripped by tongues attached by their ends at intervals along the belt, the tongues releasing the paper at the end of the working operation. The endless belt f is carried on rollers a, b, c, d, e, and has a number of pieces f <3 >of a covering layer vulcanized to the belt. These tongues have their free ends formed to present an even surface in the run, whereas at the bends the free ends project outwards. A handle g drives the roller a, whilst the shaft of the roller e is under the action of a spring o which keeps the belt taut. The drawing B is superimposed on the sensitive paper A with the edge of the latter projecting, this edge being placed under the tongue f <3>. They are both carried under the glass plate h and exposed to the lamp p. At the roller b, the drawing B projects and is removed and the sensitive paper A passes under the sheath i and over the developing box k. Development is obtained by a roller dipping into the liquid, or by vapour action only, an electrical resistance n in the circuit of the lamp p serving to heat the liquid in the box. At the roller d, where there is no cover, the tongues f<3> project and release the sensitive paper A which pass out to the apparatus.

Abstract: 1,061,276. Cooling reactors. SOC. GRENOBLOISE D'ETUDES ET D'APPLICATIONS HYDRAULIQUES (SOGREAH). April 3, 1964 [April 5, 1963; May 21, 1963; May 22, 1963], No. 13914/64. Heading G6C. In a swimming-pool type nuclear reactor the pool circulation system is sub-divided so as to provide a layer of water at the upper surface free from radio-activity. The reactor core is mounted within a vertical tubular casing, open at the upper and lower ends through which water is circulated by a pump external to the reactor tank. Separate currents of purified water are supplied to the pool surface by auxiliary circulators and these flow downwards to merge with the flow through the core. The flow in the casing may be either upwards or downwards and in both instances deflecting vanes are provided at the casing upper end to prevent flow upwards towards the pool surface layers.

Abstract: 1310901 Stretch bending A A A COUZINET 23 March 1970 [25 March 1969] 13932/70 Heading B3E A machine for stretch bending metal extrusions comprises means 5, 5a for stretching the extrusion and then bending it, the degree of elongation during the bending being indicated by means 15, 16, Fig. 3, so as to permit control of the stretching force. The metal extrusion 2 is encased in an envelope 3 of readily meltable metal alloy and the protruding ends are gripped in clamps 4, 4a, connected to power jacks 5, 5a. The middle of the extrusion is clamped to a former 6 by a screw 7. Rollers 9, 9a on the cylinders 8, 8a of the power jacks engage curved guides 10, 10d during the bending operation. In order to measure the tensile forces which elongate the extrusion a graduated steel strip 13 is unrestrainably placed along the envelope 3 of the extrusion and co-operates with a pointer 15 fixed on the extrusion. Thus an operator can read the extension and adjust the fluid pressure jacks to obtain the required degree of elongation. Alternatively, electromagnetic sensors are connected to each end of the extrusion for energizing indicators on a control panel which also has pressure gauges for the jacks and controls for adjusting the pressure. The measurement variables may be translated into actuator driving servo inputs or even computer inputs. Further the readings may be displayed on a panel by television cameras.

Title: Horizontal earth boring machine
IPC: E21B44/06
Filed: 1975-04-10
Abstract: 1457493 Augers KOEHRING CO 10 April 1975 [5 July 1974] 14681/75 Heading E1F A horizontal earth boring machine comprises a hydraulic motor 42 for rotating an auger, hydraulic actuators 48 for reciprocating a carriage on which the auger is mounted, a variable displacement hydraulic pump 92 for delivering hydraulic fluid to the motor and actuators, and a pressure compensating circuit 178. Check valves 144 and 166 associated with a control circuit for the actuators 48 and motor 42 respectively are arranged so that the higher of the working pressures existing in either the motor or actuators is made available to a signal port 148. A pressure differential between the signal port 148 and a signal line 180 communicating with the output line 106 of the pump is maintained at a predetermined level by means of a pump servo piston 176 which varies the angle of the pump swash plate 174. To prevent a power overload, the compensating circuit is provided with a power limiting control 184 having a biassing spring 186 grounded against an arm 188 connected to the swash plate 174. As the pump 92 increases displacement due to an increase in angle of the swashplate the spring 186 is relaxed requiring less load pressure in the line 180 to overcome the force generated by the spring 186, and the load pressure to which the power limiting control shifts is inversely proportional to the displacement of the pump 92. When directional control valves 102, 104 are in their neutral position, the output of pump 92 is blocked and the resultant rise in pressure in signal line 180 actuates a valve 192 to connect a fixed bypass orifice 196 with a line 198 to the reservoir 100. The orifice is selected to maintain enough pressure drop across the orifice to keep the valve 192 shifted. Since the valve pressure drop is also the pump control differential, the pump is controlled to a minimum stroke at a low working pressure.
