Abstract: 939,781. Rotary I.C. engines. G. B. LEATHER. Feb. 19, 1962, No. 6246/62. Class 110(2). A rotary internal combustion engine comprises a four sided rotor 6 rotating inside a circular section housing 1 and co-operating with spring loaded hinged abutments 4, 8 and 9, the abutment 4 serving to separate the inlet 2 and exhaust port 3. Mixture is induced on to the face I of the rotor (Fig. 3), is compressed against the abutment 8 (Fig. 4) and stored in the space containing the abutment, to be mixed with the mixture on face II (Fig. 5). The abutment 8 is raised by a cam to allow this, and the combined mixtures are compressed against the abutment 9 into a chamber 21 containing a spark plug. The burnt gas expands against face III of the rotor, the abutment 9 being raised, as in Fig. 4, to allow this, and exhausts at 3. Ignition takes place twice per revolution, expansion occurring on faces I and III. The rotor may have any number of faces which is a multiple of four, the number of ports and abutments being altered accordingly. The housing 1 is jacketed for water-cooling. Two or more engines may be connected by the same drive shaft.

IPC: A43B1/10
Filed: 1923-03-05
Abstract: 215,882. Russell, R., and Broomfield, H. March 5, 1923. Connecting uppers to insoles and soles.- Rubber footwear, such as plimsolls, are built up of sections of canvas or like material coated before or after being secured together with rubber latex which in itself may form a sole, surround, or trapping, or to which, with the aid of a rubber solvent, a separate rubber sole, surround, or trapping may be attached. The shell of the shoe may be formed by sewing together at their edges an upper section c, and a bottom section a having a margin extending about # of an inch beyond .the desired size of the shoe. The stitching is zig-zag, including running cords d. The cords are then tightened, turning the margins over on to an insole b, which has previously been cemented to the central portion of the insole. and the cords are tied. The shoe is then turned inside out and a felt or like sock e, and a canvas sock e<1> inserted. The lower part of the shoe is then dipped in latex, once if a crepe or other sole is to be applied. Vulcanizing agents, and filling colouring pigments or compounds may be added to the latex.

Abstract: 230,272. Seddon, F. March 13, 1924. Tipping-wagons.-In lorries &c. power means for tipping the. body comprises a link member pivotally connected to the body and to a crank member adapted to be driven in one direction, and means for disconnecting such members automatically from the source of motive power when the body reaches either of the extreme positions, the tipping mechanism comprises a tranverse shaft 7, Fig. 1, driven by a worm-wheel and worm 10 and provided at its ends with cranks 13 connected to the body 2 by links 14. The worm 10 is adapted to be driven from the motor-driven shaft 5 through a clutch 11 which is automatically de-clutched when the body is in its extreme tipped position or its normal horizontal position. A collar 15, Fig. 4, is mounted loosely on the shaft 7 and connected thereto by a spring 16. The collar is provided with a semi-circular track 18 in which engages a dog 19 mounted on the shaft. The collar is normally prevented from rotating by one of a pair of cams 20 coacting with a roller 21, Fig. 3. At the appropriate time, the dog 19 carries the collar 15 round so that the cam 20 pushes a lever 22 causing a lever 23 to rock to declutch the clutch 11. The spring 16 then causes the collar 15 to regain its proper relative position. The movement of the lever 22 declutches the main clutch against the influence of the spring of its pedal. The clutch 11 is moved into operative position or locked by means of a rod connected to the hand lever 27, Fig. 1. The lever 22 is cranked at 22<a> so that the spring of the main clutch pedal may reassert itself without moving the lever 23 if the clutch 11 is locked.

Title: Improvements in or relating to the production of alkali metal percarbonates
IPC: C01B15/10
Filed: 1943-04-23
Abstract: 565,653. Percarbonates. WALTERS, O. H., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. April 23, 1943, No. 6567. [Class 1 (iii)] In the preparation of an alkali metal percarbonate from a solution of hydrogen peroxide and an alkali metal carbonate or bicarbonate, precipitation is carried out in the presence of a small proportion of diphenyl guanidine, which acts as a stabilizer for the product. Preferably, the solution also contains a known stabilizer, such as sodium silicate, a soluble magnesium salt, e.g. magnesium sulphate, or gum arabic. The proportion of diphenyl guanidine used may be from 10-400 parts per million, calculated on the percarbonate which could theoretically be formed. A preferred range is from 20-60 parts per million. The reaction may be carried out either by adding the alkali salt to aqueous hydrogen peroxide and salting out the percarbonate with sodium chloride, or by adding the alkali salt to a mixture of sodium peroxide and hydrochloric acid. The reaction mixture is cooled to maintain a temperature below, or not greatly above, room temperature. The precipitated percarbonate may be separated using a centrifuge and dried in a rotary drier.

The S factor is the product of the finished catalyst average pore diameter in Š and the weight fraction of Group VI and Group VIII metals on the support, divided by the particle density of the finished catalyst in gms. per c.c. Particle density is obtained by dividing the weight of the particle by its superficial volume, i.e. the volume defined by the external and apparently continuous surface of the particle, and the A.P.D. in Š is 4 times the pore volume in ml. per gm. divided by the surface area in sq. metres per gm., all by 10<SP>4</SP>.

Abstract: 1346699 Active filters INTERNATIONAL BUSINESS MACHINES CORP 14 Feb 1972 [17 March 1971] 6756/72 Heading H3U A digital filter, wherein the incident signal is represented by digital samples with a given repetition frequency, includes means for repeating each sample a given number of times, m, at a repetition frequency which is an integral multiple, n, of the given repetition frequency. As applied to a filter of the type described in Specification 1,346,698, with m = 1, n = 2, a sample X<SP>N</SP> arriving at ED at time NT is written into register R1, and a previous sample X<SP>N-1</SP> is transferred from R1 to R2. An "AD Select" bit of "O" level addresses store ROM to retrieve the first value corresponding to samples X<SP>N</SP>, X<SP>N-1</SP>. Just before time (N + ¢)T, switches I1, I2 are closed to recirculate the contents of R1 and R2, the "AD Select" bit is changed to "1" level, and to store ROM is again addressed to retrieve the second value corresponding to samples X<SP>N</SP>, X<SP>N-1</SP>. This arrangement simulates an increase to twice the number of weighting factors, and a further increase can be obtained by increasing the capacity of registers R1, R2 and recirculating selected ones of the values retrieved, Figs. 3C, 3D (not shown). When more than two recirculations are required, problems due to operating speed may be overcome by using parallel connected registers, Fig. 4A, 4B (not shown).

Abstract: 984,671. Change-pole induction motors. TRANE CO. Feb. 18, 1964 [Feb. 27, 1963], No. 6782/64. Heading H2A. In a change-pole, shaded-pole induction motor, the number of shaded poles corresponds only to the lowest pole-number employed, but all poles carry A.C. windings which may be switched (by reversal or elimination) to change the effective pole-number. Thus, as shown in Fig. 4, windings 44 and 46 are energized to give four-pole operation, but if the supply to winding 46 is reversed, poles 16, 18, 20 and 22 are reversed to give eight-pole operation. The windings may be in series or parallel. If desired, winding 46 may be de-energized (Fig. 7, not shown) to produce the same result, these poles having the same, i.e. reversed, consequent polarities. The two-pole arrangement shown in Fig. 9 gives four poles if winding 97 and 98 are reversed, and eight poles if winding 96 and 98 are reversed. The pole windings may be of distributed concentric type.
