Abstract: 523,881. Electric control systems. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. March 15, 1939, No. 8352. Convention date, March 18, 1938. [Class 40 (i)] In a radio receiver wherein tuning is effected by a motor under the control of a keyboard and a positioning disc is provided for each station for controlling the motor, each disc is provided with two guide tracks which differ in operative height and co-operate with a control member for the motor. The guide tracks extend over an angle larger than 180 degrees and the discs are driven at a higher speed than the shaft of the tuning device. Figs. 2 and 4 show the positioning disc of one station and its operative association with a push button 35. The disc 8 is provided on its outer cylindrical surface with two helical guide tracks 29, 30 having different operative heights h<SP>1</SP>, h<SP>2</SP> and merging into each other at the depression 31. Upon operation of. the button 35, the pivoted lever 38 depresses a feeler 34 on a lever 33 into contact with either the track 29 or 30 depending on the position of the disc. The levers 33, 38 carry extensions 36, 41 which co-operate with contacts 43, 44, 45 connected in the motor circuit., If the feeler 34 engages the track 30 the extension 42 moves the contact 44 into engagement with contact 45 to close the motor circuit and cause the motor to drive the disc until the feeler 34 enters the depression 31 and the downward movement of the extension 36 operates the contact 45 to open the circuit. Operation of the feeler into engagement with the track 29 allows contact between contacts 43, 44 and causes reverse operation of the motor. In a modification, the two tracks may be arranged to merge gradually into each other; alternatively a step which makes an angle of 90 degrees or less to the track of greater height may beprovided and arranged to co-operate with a bell-crank lever which operates the motorcontrol contacts in such a manner that for one direction of rotation, the lever opens the motor circuit to stop the disc directly in the predetermined position and for the other direction the disc runs past the correct position and then is reversed into that position. In a further modification, a spiral track is provided on the flat face of the disc, the inner and outer turns of the spiral being used for operating the motor in opposite directions.

Title: Improvements in or relating to electrical bridge arrangements
IPC: G01R17/00
Filed: 1940-06-17
Abstract: 587,878. Inductance and capacitance measurements. BLUMLEIN, A. D. June 17, 1940, Nos. 8664/41 and 8663/41. Divided out of 581,161. [Class 37] A bridge of the type having closely coupled inductive ratio arms for measuring an impedance in the presence of impedance between its ends and another point such as earth comprises separate leads connecting the A.C. source and a ratio arm to that point. The bridge shown in Fig. 3 comprises closely coupled inductive ratio arms 1, 2, the impedance X to be measured, and the balancing impedance Y. Impedances Z1, Z2 are shown between the ends A, B of the impedance X and the common point C to which the ratio arms 1, 2 and the A.C. source 3 are connected. The common point of the ratio arms 1, 2 is returned to the point C directly by means of a lead 5 instead of through the lead connecting the generator 3 to the point C, thereby avoiding error due to the resistance of the lead common to the two circuits. Errors due to the impedance Z3, comprising the leakage reactance and resistance of the ratio arms 1, 2, the resistance of the connecting leads, is minimised by connecting the balance indicator 4 effectively directly across the impedance Z2, i.e. between the points B. C. by leads 6, 7 separate from those connecting the ratio arm 1 to these points. The invention may be applied to the bridge described in Specification 581,164 in which voltages having a predetermined ratio are applied to the halves of the bridge. Such an arrangement is shown in Fig. 5, in which the two voltages are supplied from transformers 11, 12. Separate leads 13, 14 and 15, 16 connect the points A, C to the windings of the transformers 11, 12. Leads 6, 7 separate from those connecting the points B, C to the ratio arm 1 connect these points to the indicator 4 through a matching transformer 10. Errors due to earth capacitances at high frequencies are avoided by enclosing the. bridge in a screening box and coupling the voltage source and balance indicator through electrostatic screens so that the box serves as an earth for the bridge. If the point C is not earthed, the screening box may be enclosed within a further screening box, which is earthed, additional earthed screens being provided around the measuring leads and between the winding of the transformers coupling the source of voltage and the balance indicator to the bridge. The balance indicator and the source of voltage may be interchanged. The inductive ratio arm associated with the balancing impedance Y may be replaced by a plurality of tightly coupled inductances associated with a plurality of balancing impedances.

Abstract: 920,464. Feeding sheets. A. S. IRMA. March 10, 1961 [March 10, 1960] No. 8832/61. Class 100 (1). [Also in Group XVII] In a machine wherein flat objects such as slices of meat or bread are placed in a pile on a support, a sheet of paper being placed between each slice by suction means, the holder 10 for the paper sheets 13 is positioned above the support 8 and the pile, and the suction means comprises suckers 18 on a tube 17 carried in oscillating arms 16 which by their movements, control a valve 37 in the supply line of the suckers so that a sheet is released above the pile. The valve 37 is electromagnetically operated when one arm 16 closes a switch 36 in the sheet-release position. The holder 10 is slightly inclined to the horizontal, a weight 14 moves the sheet pile towards the front plate 11 of the holder, and the plate 11 is cut away to allow the suckers 18 to detach the front sheet. Slices of meat &c. from a slicing machine (not shown) are conveyed by a belt 2, having transport spikes 1 thereon and are stripped off the belt 2 by tongues 5 on a member 4 pivotal about a spindle 6. The slices fall on to the support 8, which comprises a conveyer belt. The suckers 18 are oscillated from a driven shaft 30 through a cam 29 and levers 24 to 26. The shaft 30 also drives a cam 33 through reduction gears, which rocks a feeler 34 to operate a switch 35 in the circuit of the valve 37 after a predetermined number of slices has been stacked on the belt 8, whereupon the suckers 18 are cut off from the vacuum supply. The feeler 34 may also cause the conveyer belt 8 to be driven to remove the interleaved pile of slices.
