Abstract: 721,638. Springs. BAGSHAW & MORRIS, Ltd. Feb. 25, 1953 [Sept. 23, 1952], No. 23858/52. Class 108 (3). [Also in Group XIV] An elastically extensible member comprises two abutments 11, 11 at each end of a coilspring 10, two non-elastic tie members 12 located adjacent the longitudinal axis of the spring 10, and each engaging a respective abutment at one end of the spring 11 and extending through the other end of the spring to a connection-receiving portion so that extension of the extensible member by the tie members 12 causes compression of the spring 10. As shown, each tie member is formed with a U- shaped portion 12b, the parallel limbs of which are disposed within the spring 10 and serve as a guide to prevent buckling of the spring under load. Figs. 5 and 8 show alternative constructions of the loop 12c by which the tie member 12 is connected to the load. In a modification, Fig. 1 (not shown), each tie member comprises a single elongated loop. One end of the loop serves as an engagement with one of the abutments 11 as in Fig. 3. The other end of the loop serves as a connection to the load. In a further modification, Figs. 6, 7 (not shown), each tie member may be of U-shape. The loop of the U engages the abutment 11, and the arms extend through the other abutment and are doubled back on themselves to form a loop, and are secured by a binding of wire or strip 16, or by brazing. The invention is applicable to the springs of upholstery and mattresses (see Group XIV). According to the Provisional Specification, the tie members 12 may be of nylon cord.

Abstract: 903,436. Voltage detecting circuits. WESTINGHOUSE AIR BRAKE CO. July 31, 1958 [Aug. 7, 1957], No. 24661/58. Class 37. [Also in Group XL (c)] A circuit responsive to the difference between two input signals comprises two electronic devices having a common load and each connected to the signal sources such that the inputs to the devices vary oppositely and in accordance with the sense and magnitude of the difference between the input signals and so that the voltage across the load is at a maximum when the difference is within a predetermined range. In the Figure, the incorrect operation of a computer is indicated by applying a voltage from the computer to a cathode follower valve 19 coupled to a voltage comparator 29, 45, where it is compared with a reference signal derived from a potentiometer 21. The output from the comparator is fed through an amplifier 61 and a phase-splitter 69 to two valves 85, 97 having a common cathode resistor 109 and biased so that one is normally conducting and one non- conducting. As the input voltage from the computer increases the non-conducting one of the valves 85, 97 becomes conducting and the other cuts off and within a predetermined range both valves conduct and the voltage across the cathode resistor 109 increases to a maximum. The voltage is applied to a relay circuit 115 which operates near the maximum and this occurs only when the signal from the computer is within predetermined limits. The sensitivity of the circuit is controlled by a variable resistor 33 in a negative feed-back path from valve 69 and the circuit to which the relay contact 121 is connected is rendered ineffective by means of a second relay 131 when the power supply fails. It is stated that transistors could replace the valves.

Title: Improvements in metal grinding operations
IPC: B24B47/18
Filed: 1933-09-07
Abstract: 425,311. Grinding eccentric workpieces &c. HARLEY, S. J., Long Bend, Old Leamington Road, Stivichall, Coventry. Sept. 7, 1933, No. 24852. [Class 60] [See also Group XXXVII] In grinding metal work-pieces the rotational speed of the work is varied during revolution so that a constant grinding speed may be maintained while grinding eccentric work-pieces or, in grinding a fluted tap, the work may be speeded up while the wheel is passing over the flutes. In Fig. 1 the rotary contact a of a switch b is driven at the same speed as a tap being ground. The driving motor d has a speed regulating resistance e which is shortcircuited each time the arm a engages one of the fixed contacts c----c<3> corresponding in number to the flutes of the tap. In this way the motor is speeded up each time the wheel passes over a flute. In a modification the switch may have a single contact and the arm a make one revolution for each flute in the work. In another modification, Fig. 2, the resistance e is shorted by a switch f actuated by a cam g driven in unison with the work, the double cam shown corresponding to the grinding of a twoflute tap. In another modification a threephase motor is employed and a switch is operated by a cam to make and break the circuits of exciting coils of triple-pole contactors serving high and low speed windings of the motor. In another modification, Fig. 4, the field windings of a generator G and work driving D.C. motor d are both supplied with current from an exciter C which with the generator may be coupled to a main motor M. In this case a cam g<2> operates switches f<2>, f<3> adapted to short-circuit resistances e<1>, e<2> in the field circuits of the generator and motor. In a further modification a cam such as g<2> controls a resistance in the field circuit of the generator only and the field circuits of generator and motor are supplied from mains instead of from an exciter. In a similar form, Fig. 6, the regulating resistances e<1>, e<2> are each connected in series with the field windings of generator G and motor d respectively. In a machine embodiment the cam g operating the switch f through a plunger l is mounted on a spindle driven from a loose wheel n through a splined clutch k. In order to vary the times of acceleration of the work the shoulders of the cam g are formed with helical faces and the cam is axially adjustable relatively to the plunger l. In the case of grinding eccentric cams the speed controlling cam may be a replica of the work to be ground and may move a contact along a suitable regulating resistance. In another modification a constant speed motor may be employed and a control cam may operate variable speed gearing of known type to effect the required speed changes. In another form the speed changer may consist of a hydraulic pump and motor system of known type.
