Title: Signal recorder with hydraulic feed
IPC: G11B3/36
Filed: 1963-03-11
Abstract: 982,379. Recording gramophone records. KYMA CORPORATION Ltd. Feb. 11, 1963 [March 7,1962], No. 5405/63. Heading G5R. A signal recorder comprises a recording transducer supported on a carriage, spring means for urging the carriage along a path relative to a moving recording medium, and hydraulic means for regulating the speed of travel of the carriage. In Fig. 1 a stylus arm 28 is pivoted to a carriage 30 and pressed towards a record blank 14 on a turntable 12 by an adjustable tension spring 33. The carriage 30 is supported by a hollow shaft 32 the ends of which extend into bellows 46 and 56; one end plate of each bellows is secured to shaft 32, and the other end plate is secured to the casing. A compression spring 50 surrounds bellows 46 and drives the carriage 30 radially across the turntable, motion of the carriage being regulated by the passage of hydraulic fluid from bellows 46 through shaft 32 and bleed hole 58 into bellows 56; a check valve 60 allows rapid motion of the fluid in the opposite direction when the spring is re-compressed. The spring 50 is cocked by a lever 62 which turns a cam 64 which tilts the stylus arm out of contact with the record and moves the carriage to its starting position where it is held by a latch 68. After operation the lever 62 is returned to a resilient stop 74, and pressure on the lever against the stop allows a pin 72 on cam 64 to engage a lug 70 on latch 68 to raise the latch and allow the carriage to start moving. If desired the tail of arm 28 may be extended by a pin 76 adapted to be held by a plate 78 when the carriage is in its starting position, so holding the stylus away from the turntable; when a recording is started the pin will slide off the plate 78 after a short travel of the carriage, hingeing the stylus into contact with the blank record. The pin may be further extended so that when a cover for the apparatus is applied, as at 80, the stylus will be lifted out of contact with the record regardless of the position of the carriage. In an alternative arrangement, Fig. 2 (not shown), the ends of shaft 32 are connected respectively to a helical tension power spring and to the piston of a dashpot. In this case the stylus pressure is provided by the same spring that furnishes the traverse drive. High-pitch lead-in or lead-out grooves may be provided on the record if the dashpot is modified to provide increased leakage rate at one or both ends of its travel, or, in Fig. 1, if auxiliary valves are associated with shaft 62. The record may be of the audiovisual type. Specification 978,124 is referred to.

Abstract: 642,343. Presses for separating liquids from solids. CHISHOLM-RYDER CO., Inc. Feb. 24, 1948, No. 5455. Convention date, June 27, 1941. [Class 46] In a juice extractor comprising a screw 20 rotating within a screen 30 through which the juice passes and having a tapered head 28 forming with a tapered surface 34 on a fixed end head 5 a restricted annular passage 35 for the discharge of solids, means are provided for adjusting the effective size of the annular passage manually and preferably also automatically on build-up of excessive pressure in the passage. As shown, the screw 20, of large diameter, e.g., one foot, has a shaft 21 which is loosely rotatable in a boss 17 on the end head 5, and is supported by a self-aligning bearing 60-62. Interposed between the bearing and a reduced portion 22 of the shaft 21 are a flanged collar 45 and a sleeve 47 having a reduced end portion 48 (both these members being slidable on the shaft) and surrounding the bearing, and in fixed adjusted position on the boss 17 is a ring member 66 to which is secured a flanged retaining collar 70. A shoulder 23 on the shaft 21 is kept in engagement with the collar 45 by a compression spring 51 acting between an adjusting nut 52 on a screwed extension 53 pinned to the shaft, and a washer 50, bearing against the sleeve 47. The solids discharge opening 35 may be widened by screwing the ring member 66 further on to the boss 17 by a hand wheel 69, a spring member 81 engaging one of a series of detents 80. This rotation of the ring member moves the shaft 21 to the right by means of the bearing 60, collar 45 and shoulder 23. On unscrewing the ring member 66, the compression spring 51 serves to ensure tnat the shaft will move to the left with the member 66. In any adjusted position, excessive pressure of solids in the discharge opening causes the screw to move to the right against the pressure of the spring 51, the shoulder 23 leaving the collar 45 when this happens. An auxiliary thread 40 between the turns of the main thread 25 is provided at the end of the screw to assist in the expulsion of solids through the opening 35.

Title: Prevention or removal of moisture on glass surfaces
IPC: G01N27/04
Filed: 1974-02-07
Abstract: 1459248 De-misting windows CENTRAL GLASS CO Ltd and NILES PARTS CO Ltd 7 Feb 1974 [7 Feb 1973] 05712/74 Heading A4F [Also in Divisions G1, H2 and H5] A system for preventing the condensation of moisture on a glass surface comprises a pair of moisture detecting electrodes mounted on the surface, and a circuit for detecting the variation of the impedance between the electrodes, the detecting circuit including a temperature sensitive diode D which compensates for any temperature dependent variation of the impedance between the electrodes. The glass surface may be a vehicle or building window. An astable multi-vibrator MVC supplies a signal at a frequency between 100 and 1000 H z  to a bridge circuit R, R1-R3, the resistance R of which is the impedance between the pair of electrodes. A differential amplifier T 1 , T 2  is connected to the output terminals of the bridge and the diode D maintains the base current to the transistor Ti constant despite ambient temperature variations. When moisture condenses on the glass surface, the impedance between the electrodes decreases so that the amplifier T 1 , T 2  supplies an output to switch on an amplifying transistor T 3  which in turn switches on a transistor T 5 . A relay Ry is therefore energized to enable heating current to be supplied to a conductive heating film or wires mounted on the window or to a warm air device.
