Title: Method of and apparatus for rolling hot metal
IPC: B21B1/02
Filed: 1972-07-07
Abstract: 1430755 Rolling mills BRITISH STEEL CORP 5 July 1973 [7 July 1972] 32014/72 Heading B3M [Also in Divisions G1 and G3] Heating of a metal ingot before rolling is manually or automatically controlled according to the difference between a desired value for the resistance of the metal to rolling and the actual value measured on the previous ingot. The resistance to rolling is measured by one or more of the following methods; in each case the measured values are integrated over one or more passes of the ingot; (i) load cells 12 to detect roll force, (ii) the product of torque from transducer 22 and speed from tachogenerator 20, (iii) the product of voltage and current supplied to D.C. drive motor 24, using meters 30, 32, (iv) the A.C. power to motor 28 driving D.C. generator 26, measured by 34, 35. Relay circuits (Fig. 4, not shown) ensure that integration occurs only when an ingot is present; in the absence of load cells 12 a pyrometer 36 detector is used. In the case of load cells, integration is for a fixed time after rolling commences, to avoid transients present at the beginning and end of each pass (Fig. 2, not shown). If more than one method is used the integrator outputs are connected sequentially to logging equipment and also to a comparator (132, Fig. 5, not shown) for comparison with the desired value, which is determined from potentiometer settings for the weight, width and thickness after rolling. The comparator output may operate lamps (too high, too low, or acceptable) or automatically adjust a preheating furnace.

Title: Improvements in and relating to the distribution and regulation of electrical energy
IPC: H02J7/34
Filed: 1925-12-18
Abstract: 267,613. Calvert, W. J. R. Dec. 18, 1925. Systems of charging and discharging galvanic batteries; running generators in series; switching systems. - An arrangement of switches and a distribution board whereby one or more work circuits may be connected in series with one or more groups of sources of e.m.f,, such as storage cells or dynamos with or without polarization cells for voltage regulation. A charging dynamo may be connected to each group of storage cells independently as shown in Fig. 1. Each group of eight cells 1A - - 6A is connected at its positive end to a terminal +A1 - - +A6 on a distribution switch board and at the negative end to a selector switch A1 - - A6 whereby it may be (1) independently connected to distribution board terminals -A1 - - -A6, (2) connected in one or more independent series with any selected group or groups or (3) connected in series with one or other of a number of regulating switches B' - - B<3> arranged to place in series any number from none to eight of unformed lead-acid cells. The referred to and plug-ended flexible leads P1 - - 3B on the distribution switch board. This board preferably comprises sockets for the terminals inferred to and plug-erded flexible leads P1 - - P5 and D for the separate work and dynamo circuits. The arrangement is such that the positive plugs cannot reach negative sockets and vice versa and the dynamo plugs cannot reach the Rockets 1B - - 3B. The dynamo plugs are shaped to fit only special sockets connected to each of the terminals -A1 &c. +A1 &c. so that charging current cannot pass through the regulating cells. By using an auxiliary distribution board which may be connected by flexible plug leads to the regulated terminals a number of work circuits may be paralleled on any battery circuit. An arrangement is also described by which two systems of the kind described may be used in combination, a single charging dynamo serving both.

Title: Photographic camera
IPC: G03B17/52
Filed: 1973-07-05
Abstract: 1429200 Self-processing cameras EASTMAN KODAK CO 5 July 1973 [5 July 1972] 32054/73 Heading G2A  A camera for self-processing film units has a reciprocable feeder member for feeding an exposed film unit into the nip of a pair of pressureapplying rollers, one of which is couplable to a rotary power input member through a singlerevolution clutch which causes the feeder member to perform one cycle of motion, after which it is disconnected from the power input member. As shown, the feeder member is a shuttle 156 mounted for sliding movement on a shell 130 rigidly secured to the camera housing. Fingers 166 on the shuttle engage slots in the cartridge holding the stack of film units and feed it forward into the nip of rollers 140, 142. The rollers carry a series of interengaging gears 228, 152 and 150, which are engaged and driven by a gear 224 forming part of a barrel 200 mounted on an arbor 202. A lanyard 196 of a tough resilient plastics material is maintained in a wound-up condition on barrel 200 by a scroll spring 212 within the barrel. The lanyard is attached at one end to a pulling tab 198 accessible from the exterior of the camera Fig. 6 (not shown). A pawl 248 is mounted on a pivot 250 on a shuttle driver member 234, itself mounted on the arbor 202, rotation of member 234 being arranged to impart a reciprocatory movement to shuttle 156. As member 234 is rotated through a complete revolution, the shuttle is driven from its initial position to its retracted position Fig. 10 (not shown) and then back again. Pawl 248 is spring-urged so that its tooth 254 seeks engagement with a pawl wheel 226 which is coaxial with gear 224 and similarly intergral with barrel 200. When the lanyard is pulled to operate the processing mechanism, barrel 200 is rotated on the arbor 202, so that gear 224 rotates gear 228 and hence roller 142. Thus the film unit is advanced between the rollers, the carrier sheet being separated from the imagerecording sheet and being diverted down into a storage compartment 110 in known manner. Pawl 248 and pawl wheel 226 form a clutch arrangement , and after the reciprocating movement of shuttle 156 becomes disengaged, and cannot be re-engaged until after the next film unit has been exposed. Thus further pulling of the lanyard does not effect further movement of the shuttle. After the next exposure, a push button 226 (accessible from the exterior of the camera, Fig. 6 (not shown) is pressed, which re-engages the clutch so that subsequent withdrawal of the lanyard will once more initiate the processing step. The reciprocating movement of the shuttle may also be used to cock the shutter.
