Title: Improvements in or relating to nozzles of vacuum cleaners
IPC: A47L9/02
Filed: 1927-04-23
Abstract: 269,931. Carlstedt, S. M. April 23, 1926, [Convention date]. Vacuum cleaners. -The nozzles of vacuum cleaners are formed with two suction passages 2, 3 of different areas, and the suction pipe 12 is movably connected to the nozzle so that it may be brought into communication with either of the passages 2, 3. The suction pipe is attached to a member 9 sliding between lateral guides 8 to bring its aperture 10 into register with either of the passages 2, 3. Springs 14 with ends secured to the slide and to the nozzle body respectively, hold the opening 10 normally in register with the larger passage 2. Pressure exerted on the suction pipe closes passage 2 and opens passage 3 to suction, this passage giving a higher velocity suitable for collecting thread ends &c. In a modification, the slide has a circular motion about the nozzle portion, the passages in which are disposed side by side. Alternatively, connection may be made by a hollow rotary two-way valve. In all cases springs and stops are provided.

Abstract: 906,575. Rotary internal-combustion engines. DAIMLER-BENZ A.G. March 27, 1961 [April 8, 1960], No. 11111/61. Class 110 (2). In a rotary fuel-injection, mixture-compressing, I.C. engine, a fuel-injection nozzle is inclined to the wall of the engine housing such that it injects fuel in the direction of rotation of the piston into that part of the suction chamber which adjoins the combustion chamber situated in the region of a sparking plug. As shown, an engine of the trochoidal type, comprising a stationary housing 1 and a substantially triangular rotor 2 rolling in the direction of the arrow 5 by means of an internally-toothed ring 3 and an externally-toothed gear 4 fast with the housing, is fitted with an injection nozzle 11 inclined to the housing wall. Air sucked in through an inlet 6 into chamber 9 is compressed after the closure of this port and fuel is afterwards injected through the nozzle 11 so that the rich mixture is located in a zone 13 in the combustion chamber 10 and thence ignited by a sparking plug 14 located adjacent the expansion chamber. The poorer mixture in turn being ignited by the rich mixture. A second sparking plug 15 may be fitted to ensure reliable ignition of the rich mixture in the elongated combustion chamber 10 during fullload running of the engine.

Filed: 1960-03-30
Abstract: 894,350. Change-pole induction motors. GENERAL MOTORS CORPORATION. March 30, 1960 [April 6, 1959 (2)], No. 11206/60. Class 35. A single-phase change-pole induction motor has a single set of concentrically-wound overlapping coils connected in different ways to produce the different pole numbers. As shown in the 32 slot form in which each coil I, II, III and IV comprises six concentric coil sections, the machine is started as a two-pole machine with the coils connected in series by relay switch 14 a difference of phase being produced in coils I and III by phase-splitting condenser 12 connected in parallel with them by the centrifugal switch 16s. At a predetermined speed, switch 16s opens to disconnect the condenser to provide two-pole operation with coils I and II in series producing north polarity and III and IV south polarity. If speedselector switch 17 is closed, relay coil 16c is energized (through the condenser 12), thus moving contact arms 14c downwardly to reverse the polarity of coils II and III to give four-pole operation. Reversible operation is provided, as shown in Fig. 2b, by a switch 25 which serves to connect the starting condenser 22 in parallel with either coils I and III or II and IV. A modification in which the coils are connected in parallel groups is described. Some or all of the coils may be doubly wound and the sections connected in series or parallel groups. Four-pole, six-pole layouts with concentric coils arranged in three slot levels are described. It is stated that the invention is applicable to polyphase machines.

Title: Improvements in Apparatus for the Manufacture of Coke.
Inventor: SIVYER FREDERICK JAMES
IPC: C10B7/14
Filed: 1918-01-09
Abstract: 113,091. Sivyer, F. J. Feb. 2, 1917, [Convention date]. Wagons.-Coke is made by the combustion of coking coal on a truck in a closed chamber with limited supply of air. The coal is placed on trucks the end of which protrude from the chamber so as to permit air to pass into the cellular sides and bottoms of the trucks, which are formed of metal plates and I bars and channel bars. Clay luting is placed around the doors to make the truck air-tight when the truck is in position and the charge has been lighted. For cooling, the bottom space is formed with air inlets E, and the ends and sides are formed with air inlets and holes G to permit air to circulate through the ends and sides. One side M is pivoted and can be lowered for discharging the finished product. The cooling air for this side passes direct through the cellular space from an opening F to a similar exit opening.

Title: Improvements in or relating to the generation of electric oscillations
IPC: H03B21/02
Filed: 1949-04-28
Abstract: 660,068. Generating high-frequency oscillations. PHILIPS ELECTRICAL, Ltd., and BOOSMAN, H. B. R. April 28, 1949, No. 11329/49. Drawings to Specification. Classes 40 (v) and 40 (vi). The invention relates to circuits in which a beat frequency, variable continuously throughout a relatively wide range, is generated by mixing a first frequency which is variable throughout a narrow sub-range with a second frequency which can be varied in steps equal in width to the sub-range and avoids unwanted beats due to interaction of the beat-frequency or harmonics of it with the first or second frequencies or harmonics of them. According to the invention the values of the frequencies and the width of the sub-range are chosen such that one value of the first frequency, preferably its central value, is made equal to or an integral multiple of the width of the sub-range multiplied by the lowest common multiple of the integers next greater than the orders of all the harmonics of the beat-frequency that are to be prevented from beating with the second frequency. The first frequency may be not less than one-and-a-half times the beat frequency and the second frequency not less than half the maximum value of the beat frequency. In addition the second frequency may be less by one-and-a-half times the width of the subrange than an integral multiple of the sub-range width multiplied by the said lowest common multiple. Specification 622,838 is referred to.
