Patent GB-2108181-A (GB)
Title: Distributing apparatus
Inventor: SLADE PETER KENNETH
IPC: E01C23/16
Filed: 1981-10-20
Abstract: Apparatus for distributing particulate material e.g. Ballotini beads, onto a stripe of marking material A applied to a surface comprises a housing 1 vertically displaceably mounting a dispensing means 3. The latter comprises a tube 54 to which the beads are supplied, and which meters the beads through a gap between the lower end of the tube 54 and a closure plug 82, the gap being controlled by a cylinder 58. Beads emerging from the feed tube pass by gravity over the plug 82 and the outer surface of a distributing member 84 which shapes the flow of beads so that they fall in a desired pattern onto an inclined plate 12. The beads then slide down the plate 12 and through a slot 10 in the housing whence as they fall off the free edge of the plate 12 they are caught by blades 34 of a rotating impeller 30 and are propelled thereby onto the marking material A with considerable force. The marking material A is still wet and the beads therefore penetrate the material to a certain extent. <IMAGE>

Title: Method and apparatus for making a hermetically sealed food container
IPC: A23F5/24
Filed: 1981-12-09
Abstract: A sterilized container body is filled with sterilized food under an aseptic inert gas atmosphere, while a prescribed headspace is left in the container body adjacent to the top thereof. The container body is hermetically closed by a sterilized lid. Aseptic liquid nitrogen is supplied into the container body before it is closed, or an aseptic inert gas is dissolved under pressure in the sterilized food before the container body is filled with the food, whereby, a positive pressure, which is higher than atmospheric pressure, is maintained in the hermetically sealed container. The container is not easily deformed, even if it has a thin wall, and can preserve food for a long time at ordinary room temperature. Food from tank 1 is sterilized by heater 3, cooled by cooler 5 and added to cans 7 which has been sterilized in chamber 10 and cooled in chamber 11. Aseptic nitrogen is supplied to filled cans by nozzle 21a and lids 25 sterilized in chamber 24 are applied to the cans in chamber 23 under nitrogen supplied via curtain 24a min . <IMAGE>

Title: A pre-chamber for a combustion engine
Inventor: LATSCH REINHARD
IPC: F02B19/14
Filed: 1982-03-30
Abstract: The pre-chamber 2 has a portion 11 which is connected to the main combustion chamber 14 through overflow openings 15, 16. Opposite to the wall 9, the chamber portion 11 first continues as a transition 13 and then as a chamber portion 12 with a larger cross-section than and coaxial to, the chamber portion 11. An injection nozzle 18 sprays fuel into the second chamber portion 12 and at least one of the overflow openings 15 is so aligned that, during the compression stroke of the combustion engine, a swirling flow (Wo Fig. 3 not shown) takes place in the chamber portion 11 and which is applied to the surface 20 of the transition 13. A further overflow opening 16 is coaxial to the chamber portion 11 and first generates a straight flow 26 which is deflected at the end of the chamber portion 12 against the swirling flow (Wo). Both flows (Wo, 26) each generate an annular swirl (W1, W2) one (W2) of which absorbs residual gases present in the pre-chamber (2) from a previous combustion, the other of which (W1) has a high oxygen content. The swirl (W1) produces a reduction of the undesired combustion products such as soot, noise and lowers the fuel consumption. <IMAGE>

Title: Device for irradiation of objects with electrons
Inventor: GUSEV OLEG ALEXANDROVICH
IPC: G21K5/00
Filed: 1981-02-23

Title: A process for producing fibrous material from waste paper
Inventor: ORTNER DR HERBERT
IPC: D21B1/32
Filed: 1983-01-13
Abstract: A fibrous suspension prepared from waste paper by pulping (at 1), and cleansing by sorting in a screen sorter and/or cyclone (2), is temporarily heated before and/or during its passage through a disintegrating device (7) and prior to the separation of printing ink by flotation (8) or washing (and optically bleeching). The thickened suspension is maintained at temperatures above 85 DEG C during its passage through the disintegrating device (7). This allows types of waste paper, such as xerographic and offset-printed papers, which are difficult to de-ink to be cleaned, and therefore used for the production of fibrous material for paper manufacture. <IMAGE>

Title: Intranetwork code division multiple access communication system
Inventor: TORRE FRANK M
IPC: H04J13/16
Filed: 1983-03-29
Abstract: A CDMA format is used within a network to permit communication between members of the network. A predetermined set of digital code words is established for the network. A member desiring to transmit digital data selects an unused code word. A CDMA generator generates a reference code corresponding to the selected unused code word. The code word is gated with a signal from a pseudo-random noise generator, the output of which is then gated with the digital data to be transmitted to form a digital signal. A carrier signal is modulated with the digital signal and transmitted. The transmitted digital data modulating the carrier signal is demodulated to provide a digital signal. The particular code word embodied in the digital signal is determined by a corresponding PN generator and a corresponding CDMA generator which provides outputs which are gated and mixed with the digital signal resulting in the digital data being separated from the digital signal. <IMAGE>

Title: Improved manufacture of optical fibers
Inventor: PEARSON ARTHUR DAVID
IPC: C03B37/018
Filed: 1983-04-07
Abstract: Improved method of making optical fibers utilizing a technique for minimizing taper, including entrance taper, in an optical fiber preform made by the deposition of reacted glass precursor material on the inside of a tube. In one embodiment, a torch (or other heat source) deposition function is determined, which relates the amount of deposited material as a function of distance from the torch or other heat source. A velocity profile for the moving heat zone can then be determined that minimizes taper. For example, in a single mode optical fiber preform made by the modified chemical vapor deposition technique, a reduction in entrance taper in a 90 cm long preform of from about 30 cm (31) using a linear velocity profile to about 10 cm (32) with a profile determined according to the inventive technique is achieved.

Patent GB-838593-A (GB)
Abstract: 838,593. Starting prime movers; standby sources. BOSCH G.m.b.H., R. Nov. 7, 1958 [Nov. 9, 1957], No. 35766/58. Class 38 (4). A starter motor for an internal-combustion engine is provided with a control circuit which ensures that the starter motor can only be energized when the engine speed is below a predetermined minimum value. A starter motor 11 for an I.C. engine 10 is energized from a battery 17 by way of a contactor 12, the operating winding 13 of which is further controlled by a relay 40. Closure of an ignition switch 20 causes a capacitor 47 to charge up from the battery 17 by way of a resistor 54 so that a transistor T2 may become conductive upon closure of a switch 46 to energize the operating winding 43 of the relay 40, thereby to operate contactor 12 and cause the starter motor to rotate the I.C. engine 10. When the engine starts and the engine ignition system 23 ... 28 is producing ignition impulses above a certain frequency indicative of the predetermined minimum speed,. the impulses, which are amplified by transistor T1 and integrated by the capacitor 47, will reduce the charge on the capacitor 47, whereupon the transistor T2 ceases to conduct. The relay 40 thereupon drops and to de-energize the starter motor 11 which cannot then be reenergized whilst the engine speed remains above the given value. The capacitor 47 may be connected to the other side of the switch 46, in which case a slight delay whilst the capacitor is being charged is occasioned before the starter motor can be energized after operation of the switch 46. If the engine is of the diesel type the impulses may be obtained from a make-andbreak device operated by the engine.
