Title: Internal combustion devices
IPC: F02B33/06
Filed: 1974-01-04
Abstract: 1450815 Reciprocating piston IC engines J B PLEVYAK 4 Jan 1974 00351/74 Heading F1B I.C. engine comprises two pistons 7a, 7b connected by a member 60 which slides through a partition 11 containing a common combustion chamber 16, opposite ends of which are sealed alternately by a rolling ball valve-member 17, the pistons 7a, 7b sliding in respective chambers 20a, 20b each of which is provided with an inlet port 22a, 22b and an exhaust port 24a, 24b. Driving gear. Member 60 slides relative to power take-off shaft 13 which has a helical cam groove which co-operates with a ball 14, fixed relative to member 60, to produce rotary motion of shaft 13. Operating cycle Fuel/air mixture supplied by carburetter 36 is fed via change over valve 43 and check-valve 23a to inlet port 22a. As the piston assembly moves to the right in Fig. 5 the charge is. compressed and the increasing pressure moves ball 17 to the right-hand end of combustion chamber 16. During the rightward movement air drawn into chamber 20b past check-valve 27b during the previous stroke is pumped through conduits 32b and 34 to a junction 38 with the outlet pipe 39 from carburetter 36. An ejector action occurs at the junction which draws mixture from the carburetter. The. pressure in conduit 32b is fed through conduit 42b to act on piston 43 to move it to the left so that mixture is then fed to inlet port 22b. As piston 7a reaches partition 11, sparkplug 9 ignites the mixture and the combustion gases act on the piston to produce the return stroke. Exhaust gas recirculation. Ports 24a and 24b feed through check-valves 25a, 25b into a common pipe which leads to two valves 30 and 31. Adjustmant of these valves enables a proportion of the exhaust gas to be returned to the engine through pipe 35 and carburetter 36 while the remainder passes to atmosphere through pipe 29. In a modification, Figs. 1-4 (not shown) the inlet and exhaust ports are controlled by two rotary valvemembers (53, 54) accommodated with the thickness of the cylindrical wall of the chambers and gear-driven from the shaft 13. In a second modification, the output shaft has only a reciprocatory movement but is surrounded by a sleeve which revolves and drives the rotary valve-members, Fig. 6 (not shown).

Patent GB-605826-A (GB)
Title: Improvements in or relating to the production and use of alkali alginate solutions
IPC: D01F9/04
Filed: 1946-01-07
Abstract: The aggregation of impurities in an alkali alginate solution suitable for use as a spinning solution in the production of artificial silk, is prevented by the addition of about 0.01 to 0.1 per cent calculated on the weight of the solution, of a cation-active compound.  In addition to stabilising the solution, the added compounds act as bactericides.  Suitable compounds are octadecyl pyridinium bromide, undecyl glyoxaline hydrochloride (see Group IV (b)), trimethyl benzyl ammonium sulphate and cetyl pyridinium hydrogen sulphate.  The alginate solution should contain from about 5 to 15 per cent of alkali alginate.  Good results are obtained using 0.02 per cent of either octadecyl pyridinium bromide or undecyl glyoxaline hydrochloride, or 0.05 per cent trimethyl benzyl ammonium sulphate. In an example, a 7 per cent solution of sodium alginate was prepared by dissolving 87.5 kg. of commercial sodium alginate (containing 20 per cent of moisture) in 912 kg. of water, and filtered through a frame filter press dressed with swansdown, gamgec and calico.  The filtrate was divided into two parts and 0.02 per cent of trimethyl benzyl ammonium sulphate added to one part.  After six days aggregation was just visible in the control sample.  Both solutions were then spun into a 3.5 per cent calcium chloride bath using a candle filter wrapped with swansdown and nainsook in each case.  The filter for the control became blocked after 48 hours, whereas that for the solution containing the trimethyl benzyl ammonium sulphate was still in use after 150 hours spinning.ALSO:Undecyl glyoxaline hydrochloride may be prepared by heating equimolecular amounts of ethylene diamine mono-hydrochloride and lauric acid to 135 DEG  C. until all the water has been driven off. The temperature then rises to 280 DEG  C. and heating is continued at this temperature for 5 minutes to complete the reaction. 0.01-0.1 per cent of this (or other cation-active) compound may be added to alkali alginate solutions to prevent the aggregation of impurities therein in the spinning of artificial silk (see Group IV (a)).

Abstract: 957,015. Transistor switching circuits. ROTAX Ltd. Jan. 5, 1961 [Jan. 8, 1960], No. 709/60. Heading H3T. [Also in Division G3] In an electrical timing device, a transistor is cut-off until a capacitor mounted across the input terminals of the device receives sufficient charge and when the latter condition is reached, the transistor conducts to operate a self-holding relay. The invention may be used in a D.C. circuit but as described the circuit to be controlled uses an A.C. supply fed from terminal 1 via relay contact 16 to the output terminal so that a full-wave rectifier 4 is included in order to power the device. When switch 3 is operated, capacitor 9 receives a charging current from rectifier 4, the rate of charge being determined by resistor 10. A four-layer diode 13 breaks down when the potential across capacitor 9 is sufficient and in so doing, allows transistor 11 to conduct. Consequently relay 14 operates and completes at contact 16 the power lead to the controlled circuit and at contact 17 closes a self-holding circuit. Rectifier 15 is used to ensure that leakage current from the ballast network 7, 8 does not operate the relay prematurely.

IPC: G09G5/26
Filed: 1998-01-05
Abstract: PROBLEM TO BE SOLVED: To obtain a block copy design device in which the designing work of a character is easier by enabling a new character to be produced in a state in which a zoomed character is displayed on the display screen of a display means. SOLUTION: Character data as to a new character are produced in a character display range to be temporarily stored in a second memory and the temporarily stored new character data are converted so as be alloted to a second display screen frame having a prescribed position and size preliminarily determined by the coordinate values of a second coordinate system SCRN. The data are displayed on the display screen of the display means together with first display character data as second display character data. That is, when one part of registered data which are registered by being produced once is specified, the part is zoomingly processed at a ratio corresponding to necessity and it is made to be displayed on the display screen of the display means.  Thus, the confirming of the detailed part or the whole of the registration which is produced by a designing work and the cinfirming of an atmospher at the time the registration is deformed are easily performed.
