Title: Improvements in or relating to skid rails for furnaces
IPC: F27B9/30
Filed: 1956-12-13
Abstract: 838,031. Continuous metal-heating furnaces; skid rails. STEIN & ATKINSON Ltd. Dec. 13, 1956 [Dec. 13, 1955], No. 38134/56. Class 51 (2). In the soaking zone of a continuous furnace 11 for heating billets W, the water-cooled skid rails 27 are offset as at 33, Fig. 3 to take a heat-resisting alloy sleeve 28, which is welded thereto at 34, and which shields the billets from direct contact with the cooled rails, thus producing more uniformly heated billets. A pusher mechanism 30 propels the billets through the furnace from which they slide into a receptacle 31. The sleeves may extend for the full length of the skid rails or a second sleeve may be used surrounding the first, Fig. 5 (not shown). The furnace comprises a cylindrical shell 12 lined with refractory material 13 and is heated by burners 22 in tangential ports 23, supplied with a fuel-air mixture through valve-controlled pipes 17, manifolds 20 and burner pipes 21. Waste gases escape through flues 25, 26 at each end of the furnace.

The outputs of sensors measuring, e.g. heart rate, blood pressure and respiration, are compared with reference responses which may be individually adjusted for each patient, visual and audible warning being given if the difference between the outputs and the reference responses exceeds a predetermined level. The sensors may be duplicated, disparity between sensors giving a sensor fault indication. An analysis panel (Fig. 2, not shown) indicates whether each sensor output is high, low or normal. The high normal and low outputs from discriminators 2 (Fig. 3) are additionally fed to logic circuitry so that with particular combinations of sensor outputs alarm signals are given, e.g. if a low oxygen content in the blood and low blood pressure are combined with an increased heart rate. The logic circuitry may comprise electronic, fluidic, reed or relay switches.

Title: Method and apparatus for grinding
IPC: B24B5/38

Abstract: 947,354. Grinding. CINCINNATI MILLING MACHINE COOct. 26, 1961, [March, 1961] No. 38336/61. Heading B3D. A method of grinding a workpiece comprises rotating the workpiece about its longitudinal axis, advancing the rotating workpiece across an interrupted grinding face having a plurality of grinding face sections at the workpiece to effect relative traversing movement between each section of the workpiece and the grinding face section with which it is instantaneously in contact and progressively moving the rotating workpiece into said interrupted grinding face as it advances. A centreless grinding machine has a base 14 with a flat bed 15 and an upstanding portion 16. In the latter is journalled a motor-driven spindle 17 carrying a grinding wheel 18 having a number of spaced grinding faces 20 of equal diameter; these may be formed by cutting spaced annular grooves 22 in a single cylindrical grinding wheel. A swivel plate 23 mounted on the bed 15 pivotally receives a pin 24 mounted in the bed; adjusting screws 25, 26 in the swivel plate engage a stud 27 mounted in the bed and extending into a hole 28 in the swivel plate. A lower slide 29 is movable on the swivel plate 23 toward and away from the grinding wheel and is secured in adjusted position by a clamp 29a. A support 39 mounted on the lower slide 29 has a slot 40 in which a blade 41 is clamped by screws 42. An upper slide 30 is movable on the lower slide 29 toward and away from the grinding wheel and is secured in adjusted position by a clamp 30a. The upper slide 30 carries a regulating wheel housing 32 in which is journalled a driven spindle 33 carrying a cylindrical regulating wheel 34; the housing 32 pivots on the flat vertical face 30b of the upper slide 30 about a pivot pin 35 and is secured in adjusted position by bolts 36 threadedly received in the housing 32 and extending through slots 37 in flanges 38 of the upper slide 30. With the swivel plate 23 in a reference position where the axis D of the pivot 35 is at right angles to the axis A of the grinding wheel, the regulating wheel housing 32 is adjusted about the axis D so that the axis C of the regulating wheel is at angle 0 to the axis A of the grinding wheel; the regulating wheel is then trued such that a cylinder resting on the blade 41 arid contacting the grinding wheel along a line will make contact with the regulating wheel along a line parallel to the line of contact between the grinding wheel and the cylinder. The swivel plate 23 is then adjusted through an angle a to give a converging throat. A grinding throat section of constant width immediately before the grinding throat exit may be provided by trueing the grinding wheel as at 51. In a modification the grinding wheel has one or more helical grooves cut therein.

Title: A timing circuit responsive to the rate of change of flux in a saturable magnetic core which is substantially linearly dependent upon a given voltage
Inventor: FRANKLIN DONALD PETER
IPC: H03K3/45
Filed: 1959-11-14
Abstract: 966, 382. Electric analogue calculating. ELECTRIC & MUSICAL INDUSTRIES Ltd. Nov. 14, 1960 [Nov. 14, 1959], No. 38674/59. Heading G4G. [Also in Divisions H3 and H4] A circuit responsive to the change of magnetic flux in a core, and suitable for producing from input pulses output pulses of a mark-space ratio dependence upon the product of a number of quantities comprises a first winding connected in series with an input voltage source and the input of an amplifier, and a record winding connected to the output of the amplifier to provide negative feedback so that the current rises linearly in the first winding until the core saturates. In Fig. 3 an inductor S1 is connected in series with the base of an amplifier transistor VT1 and with a control voltage v. The emitter is biased to a value V by means of a further transistor VT2 through a common emitter resistor RT. When a switch SW1 is moved to contact 1 both transistors commence to conduct and current builds in inductor S1 at a rate dependent upon the difference between v and V, the build up being linearised by negative feedback from a collector current coil P1 (producing a flux # Fig. 4b), until after a period xTo switch SW1 is thrown to position 2. This causes transistors VT3 and VT4 to become conducting so that current builds up in S2 at a rate dependent upon the bias voltage applied to the emitter of VT4 from VT3 and the feed-back voltage from the collector coil P2. This continues until the core saturates whereupon the current through the coil rises rapidly, completely saturating the core and terminating the rise of flux in the core. VT3 becomes non-conducting so that its emitter impedance no longer shows the emitter resistor R8 and the latter then serve to limit the current in VT4. By changing the value of the control voltage v the flux follows the full or dotted line in 4b returning to its original value at an earlier or later time. The resulting output voltage across secondary coil S3 follows the curve 4c producing an output voltage from the rectifier T3 following the curve 4d. Accordingly, output pulses are produced having a mark-space ratio dependent upon the voltage v. Resistors R3, R4, R6 and R7 together with diodes Dl and D2 limit the emitter base voltages to a safe value. This may however be effected by diodes connected in series with the emitter circuits adapted to block most of the reverse voltage (Fig. 6 not shown). The switch SW1 may be replaced by a push-pull transistor circuit (Fig. 5 not shown). The transistors may be operated either in the saturation mode when conducting or may be operated as a high resistance. It is suggested that by cascading a number of the circuits an output may be produced having a mark-space ratio dependent upon the product of the number of quantities.
