Granted: 1971-07-26
Abstract: Machine consists of a vertical, rotating spindle, drive by an electric motor; the spindle has a slit at its upper end to house a pivoting cutter. A tube, made from stainless steel, is mounted to slide co-axially along the spindle; it bears against the edge of the cutter and controls its movements. The sliding of the tube is controlled by a rack and pinion system, operated by the centrifugal force exerted by two pivoted balance weights. The rack also operates a suction device which draws the juice and solid matter from the fruit to a collecting trough. The fruit is firmly held during the process by a cap attached to a lever at the top of the machine. The skins when emptied are used for holding sorbets. The machine effectively replaces skilled manual labour and allows large scale production.

A frequency selective vacuum tube amplifier circuit operating in conjunction with selective negative feedback quadripoles comprises four amplifier stages, the first two V1, V2 of which form common-cathode amplifiers, while the other two V3, V4 constitute two cathode followers, in between which the quadripole F is introduced, the cathodes of the first and last stages being D.C. coupled and having a common load resistor R1 across which the negative feedback signal is developed, while the input signal is fed to the control grid of the first stage and the output signal is developed across the cathode resistor R5 of the third stage. The series combination of C2, R2 and C3, R3 connected to the anode load circuits of V1 and V2 respectively serve to shape the phase response of the amplifier at the higher limit frequency so that no oscillation can occur, while a similar function is effected by the parallel combination of C4, R4 at the lower frequency limit, the " resonant " frequency being determined by the network F. Preferably bridging filters are used as the quadripoles such as a twin T network having zero output at the maximum gain of the amplifier.

Abstract: 1,143,633. Transistors. MATSUSHITA ELECTRONICS CORP. 7 March, 1966 [10 March, 1965], No. 9937/66. Heading H1K. The transistor of Figs. 3 (not shown) and 4 is distinguished from common diffused planar transistors by the three features: (a) the concentration of significant impurities in the base layer 7 where the collector-base junction 8 meets the surface of the body is such as to give a low impurity gradient and consequent high breakdown voltage; (b) the emitter-base junction 9 is formed by uniform diffusion over the entire surface of the body so that lattice disturbance (and consequent loss of injection efficiency) at the junction caused by the high doping level of the emitter region is reduced compared with the case of localized diffusion to form an imbedded emitter region, (c) the capacitance between contact areas 15<SP>1</SP>, 16<SP>1</SP> and the substrate (collector) is kept low by the provision of two-intervening PN junctions 8<SP>1</SP>, 9<SP>1</SP>. In an example, the manufacturing stage of Fig. 7 is reached by diffusing antimony (from dry nitrogen saturated with antimony tetroxide) into the surface of a 1 ohm cm. N-type silicon wafer to form a heavily doped layer 2, by oxidizing the surface in wet oxygen, by removing a rectangular annulus of the oxide 3 and diffusing in boron (from nitrogen saturated with boron monoxide) to form the region 5, and then by diffusing gallium through the oxide film now existing over the entire surface and through the heavily doped N-type layer to form an underlying P-type layer 7. The transistor shown by stepped section in Fig. 4 is obtained by photoresist etching a groove 10 in the semi-conductor body, by completely removing oxide films and growing a new oxide film 11 through which holes are made to expose the emitter region 2 and base region 5, by evaporating aluminium over the upper surface of the body, by removing excess metal by photo-etching to leave emitter and base contacts 15 and 16 which extend over the oxide to provide regions to which leads 17, 18 are attached, and by removing the incidentally formed diffused layers and oxide layers from the lower surface of the body.

Chloroprene, styrene and acrylonitrile are copolymerized at 30-65‹ C. to a terpolymer wherein the amounts of styrene (St) and acrylonitrile (AN) units in the total polymer are given by satisfying simultaneously the following inequalities: St > 0À2; 0À2 <AN < 2À24; 0À7 - AN < St < 4À0 - 1À7 AN all in weight per cent. The polymerization is carried out in aqueous emulsion using a potassium persulphate initiator.

Abstract: 1,227,458. Balances. HAMILTON WATCH CO. Sept,20, 1968 [Jan. 25, 1968], No.44921/68. Heading G3T. The rate of oscillation of a balance wheel 10 is regulated by moving weights 50, 52 carried thereby along seperate predetermined paths at least one of which is curvi-linear. In the embodiment illustrated in Fig. 2 the weights 50, 52 have pintles engaging in curvi-linear slots 54, 56 in the balance wheel 10 and further pintles engaging in longitudinally extending slots 42, 44 in a lever 38 pivotably mounted on a pinion 40. Regulation is effected by rotating the lever 38 to move the weights 50, 52 in the slots 54, 56 which are so formed that the centre of gravity of the lever weight system remains at the pivot 40 throughout the movement. Since the slot 54 is concentric with the balance wheel 10 and the slot 56 is not, the movement of the lever weight system changes the moment of inertia of the balance wheel and thereby its rate of oscillation. In alternative embodiments a lever or disc carrying a weight is rotatable to cause a second weight to move in a curved slot in the balance wheel; and in a further embodiment a weight is carried by a gear wheel which is rotatable to revolve an outer rim portion of the balance wheel which carries a second weight. Specification 1,125,515 is referred to.

Abstract: 1,228,950. Swash-plate pumps. SHIMPO KOGYO K. K. Dec.17, 1968 [Dec.22, 1967], No.59876/68. Heading F1A. To reduce wear between the stationary swashplate 4 and open ended cup shaped slippers 9 of a swash-plate pump in which hollow cylinders 8 are axially movable in bores 2 and forced into engagement with slippers 9 by means of spring 11 oil pressure acting directly on the swash-plate through the cylinders 8 and ports 10 in the slippers 9, each bore 2 diameter D 1  Fig.3 (not shown) is made equal to the slipper abutting portion (D 2 ) of the corresponding hollow cylinder 8 and to the diameter (D 3 ) of the open end of the associated slipper 9.

Abstract: 1,252,237. Centrifugal compressors. SCHWERMASCHINENBAU "KARL LIEBKNECHT" MAGDEBURG KOMBINAT DIESELMOTOREN U. INDUSTRIEANLAGEN VEB. Feb. 12, 1970, No. 6849/70. Heading F 1 C. A turbo charger compressor 4 and a downstream air cooler 7, for delivering air to a Diesel engine, are cleaned during temporary shut-down by injecting a mixture of steam and washing agent through nozzles 3. The mixture thereby causes the compressor rotor to rotate and subsequently passes to atmosphere as shown at 10 via diffuser 5, housing 6, cooler 7 and flap valve 8 which during the cleaning process closes the air path 9 to the engine as shown. During the cleaning process the cooler may condense the steam so that the discharge flow 10 comprises only liquid. The steam is supplied via valve 1, 1 and is mixed in an injector 1 with washing agent supplied via valve 1, 2. After cleaning, any corrosive residue can be removed by a neutralizing liquor in the same manner as for the cleaning process. For Figure see next page
