Abstract: 474,077. Indicating liquid level. CLENNELL, W. J. Feb. 24, 1936, No. 5466. [Class 123 (i)] A device for indicating when the level of liquid in a liquid - fuel tank has risen to a predetermined level comprises a cylindrical vessel 1 mounted on the top of the tank 10, and having a series of openings 3 at the top. A float 2 with a central aperture is mounted on a stem 4 guided by a plate 5. When the cover 7 is removed, liquid rising in the tank overflows at the level 3 into the vessel 1 and the float 2 lifts the indicating head 6. A guard 9 prevents the entry of surging liquid. The vessel 1 can be emptied by using the piston and rod as a pump, the sliding member 8 closing the aperture in the piston, or alternatively, a non-return valve may be provided in the bottom of the vessel 1. The rise of the float may actuate electrical or other signals or may actuate electrical means to cut off the fuel supply.

Title: Method of and apparatus for distributing comminuted tobacco, in particular tobacco leaf particles
IPC: A24C5/39
Filed: 1968-02-02
Abstract: 1,147,316. Feeding tobacco. HAUNI-WERKE KÍRBER & CO. K.G. 2 Feb., 1968 [11 April, 1967], No. 5540/68. Heading A2C. In an apparatus for distributing comminuted tobacco, such as fragmented tobacco leaves or tobacco leaf particles, tobacco 2 is removed from a supply container 1 by paddles 12, compacted at constant pressure by tamping members 18, conveyed after compacing by a spiked roll 4 on which it is adjusted to a constant thickness by another spiked roll 6 rotating as shown by the arrows, and then beaten out of the spaces between the spikes 7 of the roll 4 by a beater roll 43 and thence projected by a winnower roll 44 on to a conveyer 46 which feeds it to a tobacco duct wherein it forms a fleece. A pin roll 16 feeds tobacco from the top edge of the supply down to the paddles 12. The tamping members 18 are each actuated by an eccentrically mounted cam 28, the cams 28 being disposed offset relatively to each other so that adjacent tamping members 18 operate out of phase with each other. Two micro limit switches, connected in series and actuated by stop members 31 rigidly connected to two of the tamping member (18a, 18b) actuation mechanisms, cause the tobacco 2 to be fed forward on a conveyer belt 3 for a preset time whenever the level of tobacco beneath the members (18a, 18b) falls below a preset level. In another embodiment, three parallel tobacco supplies feeding a single spiked roll (104) is each controlled separately by one of its associated tamping members (118a, 118b and 118c respectively).

Title: Improvements in devices embodying germanium and in the manufacture of such devices
IPC: H01L31/00
Filed: 1952-03-06
Abstract: 723,996. Semi-conductor devices. SYLVANIA ELECTRIC PRODUCTS, Inc. March 6. 1952 [March 10, 1951], No. 5893/52. Class 37. An electrical translator is produced by heating germanium, having molten zinc in contact with one or more localized regions of the germanium surface, cooling to solidify the zinc and chemically dissolving the zinc to produce a small crater at each region. Zinc granules may be deposited at selected points on the surface of a slice of N-type Ge which is heated to between 600‹ and 800‹ C. for three hours and then cooled. The surface is then treated with nitric acid and an etching solution such as hydrofluoric acid, nitric acid and cupric nitrate which removes all traces of zinc and leaves small craters having good photo-sensitive properties. If the temperature is restricted to 630‹ to 680‹ C., the photo-voltaic characteristic is improved. Fig. 7 shows a photo-electric device in which point contact 116 engages a zinc processed crater formed in the surface of a germanium body 114. Infra-red radiation penetrates cover 112 and the germanium to the crater area. Photo-conductive and photovoltaic effects are produced between electrodes 116 and 118. A multiplicity of these devices may assemble in one holder as shown in Fig. 9. A further arrangement is described in which the light is incident on the surface bearing the point contact. A second point contact may be used as the second electrode in place of electrode 118. Fig. 8 shows a transistor, in which one point contact electrode 116a engages a crater on one surface of a germanium wafer, and the other point contact electrode 116b engages the opposite surface adjacent the first electrode. The wafer is supported in base electrode 118a and electrode supports 110a, 110b are made opaque to eliminate light effects on the germanium. The two point contact electrodes may be situated on the same side of the germanium wafer.

Title: Improvements in or relating to a hydraulic control device for a hydrostatic drive
IPC: F16H61/46
Filed: 1957-02-21
Abstract: 813,658. Fluid-pressure servomotor control systems. GESELLSCHAFT DER L. VON ROLL'SCHEN EISENWERKE A.G. Feb. 21, 1957 [Feb. 21, 1956], No. 5956/57. Class 135. A control device for adjusting the displacement of an hydraulic pump driven by an electric or diesel motor in such a manner that the pump absorbs a constant power irrespective of the quantity of fluid delivered has linkage means between a displacement adjuster 7 and a device 14 for measuring the delivery pressure which gives a hyperbolic relation between the displacement and the pressure so that the product of the pressure and the quantity of fluid delivered, which is a function of the displacement, is maintained substantially constant. The pump in the embodiment described is a variable swashplate pump connected by a link 8 to the adjuster 7 which is loaded by a spring 11, and having a delivery conduit 4 to apparatus to be driven by the pump and a connection 16 to the pressure measuring device 14 which consists of a piston 15 controlling fluid passageways leading to and from the adjusting piston 7 and having an abutment with a lever 21 which has a normally fixed pivot 27 at its left-hand end. Upon an increase of delivery pressure the piston 15 is raised to connect the conduit 16 with a conduit 12 to apply pressure to the upper side of the piston 7 to cause a reduction of pump displacement whilst a reduction of delivery pressure causes downward movement of the piston 15 whereby a conduit 13 leading from the top of the piston 7 is vented to an outlet 40 causing the pump displacement to be increased. Adjustment of the pump displacement is transmitted through a link 18 and a spring-loaded link 19, 20, 22 pivoted at a fixed point 24 to the lever 21 to obtain the requisite relation between delivery pressure and displacement. When the delivery pressure reaches a certain value it is desired that no further increase should take place despite further reduction in the delivery from the pump and at this point a spring 29 loading the pivot 27 comes into operation. The pressure at which this change takes place may be adjusted by adjusting the initial compression of the spring. The relationship between the pressure and the displacement of the pump may be varied by adjustment of the pivot point 24.

Headings F4H and F4U. A liquid or semi-liquid is atomized, the droplets are superficially frozen in a stream of gas, and the freezing is completed in a fluidized bed. The process may be applied to liquid foods, e.g. milk, coffee or fruit juice, and may form part of a freeze-drying process. As illustrated, a blower 5 circulates nitrogen, which is cooled at 8, through a fluidization plate 4 and a tower 1. Liquid is atomized at 2 and is superficially frozen by the time it falls to become part of the fluidized bed on the plate 4. An extension of the bed serves as a temperature equilibrating zone and leads frozen particles over a wall 16 to an outlet 15. Nozzles 12 may be provided above the bed for injecting into the tower 1 a gas which is colder than that passed through the bed. Any fine particles entrained by the gas flow are separated by a cyclone 9. Excess gas escapes through a flue 13.
