Title: Transducer with improved signal winding
IPC: H01F29/14
Filed: 1962-03-26
Abstract: 971,788. Measuring electrically; voltage and current measurement. LEEDS & NORTHRUP CO. March 26, 1962 [April 10,1961], No. 11449/62. Headings G1N and G1U. In a modification, Fig. 4, of the transducer described in Specification 971,787 in which linear displacement of permanent magnet probe 31a from a reference position produces a net D.C. flux in a magnetic circuit comprising a ring core 11 of low loss magnetic material such as a ferrite and two poles 13, 14, preferably of metal, extending perpendicular to the plane of the ring, so that variation of the reluctance of the magnetic circuit due to periodic saturation of the ring core 11 produces changes in the level of D.C. flux which induce an A.C. signal in an output winding 17, the output winding 17 encircles the ring core 11 in such a way that it is in substantially zero-coupling relation with a saturating winding 12, Fig. 5, on the ring core 11. The saturating winding 12 is symmetrically disposed on opposite sides of the ring core 11, and the output winding 17 is supported on a preferably insulating rectangular former 63 and is provided with electrostatic shielding 62. To compensate for any lack of symmetry, a resistor 3, Fig. 1 is shunted across one half of the saturating winding 12. Bosses 11a located on ring core 11 at the positions of contact with poles 13, 14 provide increased mechanical strength and minimise the passage of stray flux from the ring into the poles. Fig. 1 depicts the modified transducer connected in a voltage recording arrangement. An unknown D.C. voltage E, is converted to A.C. by a vibrator 41, amplified at 43, and supplied to the control winding of a 2-phase motor 44 which operates to position the pen and index 46a of a recorder 46 and also to displace permanent magnet probe 31 between limits imposed by stops 34. The feedback current to windings 23a . . . 23d is dropped across a resistor 24 in opposition to E x , and when equilibrium is reached the position of pen and index 46a indicates the strength of E,. Potentiometer 16 in the feedback circuit is adjusted to determine the span of the arrangement, and a temperature sensitive resistor 15, shunted across potentiometer 16, compensates for variations of temperature.

Title: Improvements in substance-holders for slicing machines
IPC: B26D7/02
Filed: 1934-04-19
Abstract: 426,101. Slicing-machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd., and THOMAS, H., Aden Road, Ponders End, Middlesex. April 19, 1934, No. 11779. [Class 28 (ii)] In a slicing-machine, the substance-holder comprises a base on which the substance rests, and one or more long prongs which enter deeply into the side of the substance in a more or less horizontal plane and, when in the operative position, extend above and wholly or considerably across the base. In the figure, two pairs of curved prongs 13, 14 are provided, each pair being carried by an arm 15 hinged at 16 to the outwardly directed flange portions 12 of the side walls 11 of the base 10. The prongs are withdrawn by pulling the arms 15 outwardly, this movement being limited by stops 17. The prongs are guided by sheaths 18 slidably mounted in the walls and urged outwardly by springs 19. When the arms 15 are swung to project the prongs fully into the substance, the sheaths 18 are pressed inwardly, but when the prongs are fully retracted, the springs 19 hold the sheaths in the outer positions in which they shield the prong points. In a modification, straight prongs, arranged to project obliquely over the base, are used In a further modification, a single prong extends slidably through a pivoted bracket so that, when the prong is inoperative, the bracket may be swung to allow the prong to lie along the outside face of one wall 11. When it is operative, the spiked end is received in a socket or guide in the wall 11 opposite to the wall carrying the bracket. The bracket has a spring-pressed ball which engages one or the other of two grooves in the prong, according to whether the prong is projected or retracted. The bracket need not be pivoted, in which case, the prong is again fully projected after removal of the substance, the spiked end being shielded in the socket or guide in the opposed wall 11. A substance-holder may be provided with more than one straight prong or with one or more curved prongs ; or with one or more of each. The substance holder may be detachably connected to the feed-member by the interlocking engagement of pins on the feed-member with holes 30 in the base 10. Alternatively, the base 10 may be provided with holes to register with the usual substance-piercing pins or spikes on the feed table, in which case, the usual top clamp is lowered on to the substance to maintain the holder against upward movement. The substance-holder may be detachably connected at one side to a feed carriage.
