Abstract: 1,052,603. Hydrocracking. MOBIL OIL CORPORATION. Aug. 16, 1965, No. 34986/65. Heading C5E. A hydrocarbon charge which has an initial boiling point of at least 204‹ C., a 50% point of at least 260‹ C. and an end boiling point of at least 316‹ C., and contains components capable of producing coke under hydrocracking conditions is hydrocracked by contacting it with hydrogen and an active crystalline aluminosilicate at a temperature not exceeding 421‹ C. and subsequently removing the carbonaceous deposit from the catalyst without oxidative regeneration thereof by subjecting the spent catalyst at an elevated temperature of at least 204‹ C. to an atmosphere consisting essentially of hydrogen. The preferred catalyst is a crystalline rare-earth aluminosilicate of pore diameter 6-15 Š, which may be steamed. The silicate may be suspended as particles of less than 10 microns in a matrix of clay or inorganic oxide gel.

Ceramic articles, e.g. saucers, are formed within a plurality of die boxes 21 carried by a horizontal turntable 10 which is successively indexed at a number of processing stations whereby clay dust is fed into the die box at a station a (Fig. 6, not shown) which is consolidated and pressed at a station b and, at a pick-up station c, the formed saucer (25) (Figs. 1-4, not shown) is raised upon pneumatic pressure actuated lower die (20) into contact with one of a number of suction holders 30, which are carried on a turntable 44, whereby the saucer (25) is engaged and transferred on turntable 44 to an auxiliary processing station e (Fig. 6, not shown) where it is rotated about its own axis, for a finishing operation, by belt drive to a pulley 31 on the suction holder spindle 32. The indexing of turntables 10 and 44 is synchronized by, e.g. Geneva or other intermittent drive arrangements. The suction holder 30 comprises a central face plate (33) (Fig. 4, not shown) provided with a resilient cushion (33a) which abuts the saucer (25) and is carried by a slidable plunger (36) (Fig. 1, not shown) for adaptation to the surface of the saucer; a flexible lip 34 effects a seal when suction is applied through a spindle duct 35 in synchronization with the other movements of the apparatus.

Abstract: 1,226,467. Exposure meters. ASAHI KOGAKU KOGYO K. K. April 24, 1969 [June 5, 1968], No.21089/69. Heading G2A. An exposure meter, including a light-sensitive element, e.g. a photo-conductor 1, has an additional photo-conductor 5 connected to its battery 4 to act as a switch. The element 1 is connected to one coil 2<SP>1</SP> of a differential indicator 2, and a variable resistor 3, coupled to camera exposure and diaphragm setting rings, is connected to the other coil 2<SP>11</SP>. The indicator 2 shows the same reading at the correct exposure as it does when the meter is switched off. When the camera is stored in the dark the element 5 becomes highly resistive reducing battery drain. When the camera is in use, the element 5 becomes conductive. This avoids the danger of confusing the power-off condition with the correct exposure condition, which may be encountered with a conventional switch. The additional element 5 may be incorporated in a bridge type circuit Fig. 2, (not shown).

In a further embodiment Figs.3 and 4 (not shown) a probe is provided with plates having holes through which water may pass. These holes are blocked by turns of wire but become gradually uncovered as the wire is paid out on descent.

The supply for the oscillator is derived from the recurring pulses. A thermistor (Th) Fig.2 (not shown) mounted in a heatable roller forms part of a multivibrator (Q1, Q2) and varies the mark-space ratio of the output which switches a Colpitts oscillator (Q3 &c.) connected to the heater supply input slip rings. These are led through an amplifier and amplitude limiter A also a demodulator Dm to an integrator I which provides a D.C. output of magnitude dependant on the mark-space ratio. The integrator output is fed together with a 100 cps linear sawtooth voltage from a ramp generator Rg synchronized with the supply to an AND gate which provides an output only when the sawtooth input is equal to or greater than that from integrator I which output switches a bidirectional thyristor or triac Sw each half cycle with a variable angular delay which supplies current to a heater (H) embedded in the roller.

Abstract: 1296137 Deaf aids K SCHOEPS 6 April 1970 [29 July 1969] 16174/70 Heading H4J A hearing aid employs an electrostatic microphone and a directional receiver and is arranged to eliminate acoustic feedback. As described the polarization voltage for the microphone is provided by an electret, by a direct current transformer or a separate power source. The output of the microphone is amplified by a fieldeffect transistor which may be in an integrated circuit. The receiver is either a pressure gradient receiver or a pressure gradient/pressure receiver. The direction of orientation of the receiver relative to the microphone is such as to reduce acoustic feedback. The directional characteristics may be adjustable by the wearer. It is stated that for electrostatic receivers of the pressure type elastic damping is required and for those of pressure-gradient type frictionchecked damping is required and that this is compatible with the small dimensions of a hearing aid allowing the resonance points of the aid to be outside the transmission range.
