Title: Improvements relating to engine starting apparatus
IPC: F02N99/00
Filed: 1943-09-06
Abstract: 567,954. Engine turning-gear. C.A.V., Ltd., and NICOLLS. W. E. W. Sept. 6, 1943, No. 14546. [Class 7 (v)] Starting means for an engine comprises an auxiliary internal-combustion engine a connected through a one-way clutch n to the sun pinion c of an epicyclic gear, the annular ring d of the gear being driven by a reversible electric motor b and the planet carrier f being connected through shaft i, one-way clutch o, reduction gear j and over-load clutch k to the starting jaw m. The engine a is first started by energizing the motor b in such direction that the planet carrier f is locked and the sun-wheel is driven to rotate motor a. When this motor runs, the electric motor is reversed and motion is then transmitted to the carrier f and the engine to be started by the joint action of both power units. If only the electric motor is to be used, it is driven in the appropriate direction while the sun pinion is locked bv the clutch n. In a modification, the electric motor is unidirectional and serves the sole purpose of starting engine a, being electromagnetically braked when the engine a has been started.

Title: Improvements in or relating to coin testing devices
IPC: G07D5/02
Filed: 1939-05-17
Abstract: 528,898. Testing coins. BRECKNELL, MUNRO & ROGERS (1928), Ltd., DOLMAN, H. J., and HASTED, H. C. May 17, 1939, No. 14670. [Class 27] A coin testing device comprises an entry runway 2, 3 which is inclined both downward and laterally. The coin 41 is led to a pocket 11 pivoted at 7 and counterbalanced at 21, and provided with a rear abutment 42 and a bottom 19 turned up at the front 20. The thickness of the coin is tested by side feelers, one of which consists of an adjustable but fixed point 27 and the other a point 40 projecting from a pivoted framework 134. A pointed member 34 projects from this framework, and is adapted to pass on one side or the other of a fixed adjustable abutment 44 according to the thickness of the coin. With a too thick coin the member 34 passes on the further side of the abutment 44 and is forced thereby further in the same direction, so that a projection 38 on the framework 134 strikes against the pocket side and causes the abutment 44 to hold up the pocket in its downward swinging movement, and to shoot out the coin into a discharge gap to the right of a fixed anvil 12. With a correct thickness coin the pocket is allowed to swing down further to tip the coin on to the anvil 12, when, if of the correct resilience, it will bounce off over a division 14 into an acceptance passageway. If the resilience is not right it will fall down the gap between the anvil 12 and the division 14 into "rejection," and this will occur also if of the correct thickness but excessive weight, as the pocket 11 will then swing down too far for the coin to strike the anvil. If the coin is too thin it will remain in the pocket, as this will not be depressed sufficiently by its weight to tip it out, and a subsequently inserted coin will lever up the pocket again and together with the first coin will form a too thick assemblage, both coins being then rejected. Alternatively, clearing mechanism may be provided suitable for separate manual actuation, in which pressure of a button, or an' attempt to operate the delivery mechanism, will cause the runway 2, 3 to turn aside and will open the points 27, 40 to release the coin.

Title: Drying apparatus and method of drying material
IPC: F26B17/28
Filed: 1957-05-08
Abstract: 866,596. Drying fabrics. FLEISSNER, H., FLEISSNER, H., and FLEISSNER, G., [trading as FLEISSNER & SOHN MASCHINENFABRIK]. May 8, 1957 [June 27, 1956], No. 14679/57. Class 34(1) Drying apparatus comprises a drier 10 for drying fibrous material passing therethrough; known measuring means (not shown), for determining the moisture content of the material leaving the drying apparatus and disposed on or near a discharge roller 14; an outlet 13 in the drier for moist air and a damper or valve 17 in the outlet 13 for controlling the rate at which moist air leaves the drier; and control means (not shown) for automatically regulating the damper 17 in accordance with the moisture content of the material leaving the apparatus as determined by the measuring means. As shown the material enters the drier 10 by a conveyer 11, passes around perforated rotating drums through which air is drawn by suction fans and thereafter leaves the drier on a conveyer 12. The air enters the drier through any suitable means (not shown) and passes through the wet material into the drums and is finally discharged through the outlet 13. Heater 18 controlled by thermostats 19 are provided for each drum which may be separately controlled or controlled by the measuring means near the roller 14, whereby the air temperature may be graduated from one drum to the next. When the material is too moist, the damper will be opened so that the moist air can be expelled at a greater rate and when the material is too dry the damper will be closed, more or less, to reduce the amount of air discharged. In another embodiment the material leaving the drier 10 is passed into a disintegrator where the fibres are loosened and. thence into a circulating air drier from which it is discharged on to the conveyer 12. The measuring means is then disposed near the discharge outlet of the circulating air drier. If desired the measuring means may be provided in the first drier and the material passed through the disintegrator with a circulating air drier having a humidity control operable by a second measuring means disposed at the discharge outlet of the circulating air drier.

Title: An improvement in or relating to multi-ratio gearboxes
Inventor: ASHFIELD HERBERT EDWARD
IPC: F16H47/02
Filed: 1960-04-28
Abstract: 943,008. Change-speed control. DAVID BROWN INDUSTRIES Ltd. May 16, 1961 [April 28, 1960], No. 14856/60. Heading F2D. An auxiliary variable-speed hydrostatic gear is provided to facilitate changing speed in a main change-speed gear. As shown, a main change-speed gear of the constant mesh type comprises an input shaft 10, and a lay shaft 11 and an output shaft 12 which drive primary and secondary pumps 25, 26 forming the hydrostatic variable-speed gear. Double dog clutch members 21, 22 are shiftable by shift rails 23, 24 to connect gears 13 and 16, 18, 20 to the output shaft 12 for direct and reduced drives, movement of a shift rail in the direction for engaging a gear being first limited by a balk member 73 or 74 abutting the end of a groove 71 or 72 in the rail 23 or 24, in which position the dog clutch member is disengaged, but a valve groove 55 or 56 in the rail opens a selected pair of ports in a control cylinder 30 to exhaust. The pumps are of the swash-plate type, pump 25 having a variable inclination swash - plate controlled by a piston 29 in the cylinder 30 and pump 26 being of the fixed displacement type although it may also be of the variable displacement type if desired. The opening of the selected pair of ports of cylinder 30 to exhaust enables the variable inclination swashplate to readjust itself until the piston 29 is positioned between the pair of ports, differential pressure in the main hydraulic transmission lines 27, 28 displacing a valve 34 so that a make-up pump 38 supplies liquid to the appropriate end of the cylinder 30 through a line 32 or 33 to aid movement of the swash-plate. When the shafts 11, 12 are rotating in the desired ratio the differential pressure in the lines 27, 28 ceases and a valve 76 resumes its central position in which it ceases to lock the balk members 73, 74 and allows the shift rail to retract the associated balk member and engage the desired gear. In a modification, the constant-mesh gear is replaced by a gear having wheels on the output shaft axially slidable into mesh with wheels on the layshaft.

Abstract: 239,311. Woosnam, A., (Gottschalk, O.). June 19, 1924. Teaching mechanics and geometry; models.- Apparatus for demonstrating or solving engineering problems, such as stresses in structures, or for drawing curves, comprise a series of composite carriers each consisting of a member 2, Fig. 1, sliding along a common rule or base 1, a member 3 pivoted to the member 2, and a slide 4 sliding through the member 3 and having a head 5 to support or load an elastic curve-forming strip or a skeleton model of a structure. The slides 4 and members 3 are held in adjusted positions respectively on the members 3 and 2 by leveroperated screws 11 and screws 9, the latter surrounding screws 8 holding the members 2 to the base 1. Screws 10 on blade springs on the members 3 co-operate with holes in the members 2 to hold the slides 4 at right-angles to the base 1 when required. The base 1 may be straight or curved and has apertures 21 at the ends to facilitate mounting on a support. The heads 5 may have knife-edge supports or screw-actuated flat clamps for skeleton structures or strips of steel, celluloid, &c. One or more screw-actuated heads 15, Fig. 5, co-operating with fixed abutments 19 and separate from or arranged on the heads 5, are used to clamp two strips 7 at a right-angle or at other fixed angle. Two clamps 17, Fig. 7, at the ends of arms 20 of a parallel-motion linkage adjustable on the heads 5, are used to secure two elastic strips 7 or models at a distance apart in determining shearing stresses in a continuous beam. The curve of bending movements in a loaded beam and bending moments in a structure may be determined by the shape of the elastic strips, for example, when one head of a number of heads supporting an elastic strip is moved out of alignment with the others, or when two strips joined at an angle by a clamp 15 are supported by aligned heads. A cord 14, Fig. 11, around rollers 13, 12 on the members 3 and slides 4 is used to move several slides 4 collectively in producing or drawing mathematical curves, or in reproducing the effects of loads on structures; for instance, to produce a circular arch, the second and fourth of five slides 4, Fig. 11, carrying a strip 7 are fixed and the first and fifth are moved together by the cord 14 by movement of the centre slide. Beam reinforcements are represented by short strips secured to the main elastic strips. The rule 1 and slides 4 may be graduated and have micrometer screw adjustment.
