Patent GB-102746-A (GB)
Title: An Improved Coin Freed Amusement Machine.
Inventor: JOFEH JOHN
IPC: G07F17/32
Filed: 1916-01-07
Abstract: 102,746. Jofeh, J. Jan. 7, 1916, Race games, mechanical.-Relates to apparatus of the type in which two figures or sets of figures, adapted to be actuated by the rotation of two external handles by two competitors, take part in a miniature tug-of-war or other contest the result of which depends on the relative speeds of rotation of the operating-handles, and consists in the use of actuating-mechanism such that the positions of the figures vary continuously during the progress of the contest, but these variations of position form no indication of the final result. The figures 21, represented as engaged in a tug-of-war, are attached to a sliding bar 22 connected to an oscillating lever 20. Spindles 12, 13, on which the operating-handles (not shown) are mounted, serve to operate driving-pawls 7, 32 and 6, 28 respectively. The pawls 6, 7 both rotate a ratchet 3 on a shaft 2, on which is mounted a cam-disk 18 co-operating with a roller 19 on the lever 20, the rotation of the cam disk serving to oscillate the lever and move the figures to and fro. The pawls 32, 28 serve to operate rack-bars 30, 26 slidably connected with stops 52, 27a, which serve to determine the result of the game. The pawls 7, 32 are operated by eccentrics 9, 33 on a spindle 11 driven from the spindle 12, and the pawls 6, 28 by eccentrics 8, 29 on a spindle 10 driven from the spindle 13. If the spindle 13 is rotated more rapidly than the spindle 12, the stop 27<a> trips a detent 54 from engagement with a pivoted plate 24, which is thereupon moved clear of a deep notch 23 in the cam-disk 18 by a spring 56, the roller 19 entering the notch permitting the lever 20 to oscillate sufficiently to draw the left-hand figure 21 over the centre line. If, however, the spindle 12 is rotated more rapidly than the spindle 13, the stop 52 is moved into the path of a rod 28<a> carrying the stop 27<a>, so that the stop 27<a> is prevented from freeing the plate 24, which moves the lever 20 to the left, drawing the righthand figure over the centre line. The legs 88, 88', Fig. 4, of each figure move independently of one another, being mounted on a spindle 89 and sleeve 90 respectively, and are caused to rise and fall as the figure moves backwards by the engagement of levers 95, 96 with fixed pins 97. The disk 3 is normally locked against movement by the engagement of pins 57, 61 with levers 59, 63, the pawls 6, 7 are held up by brackets 65, 66 on the disk 3, and the pawls 28, 32 by rods 36, 37 connected to a bell-crank lever 43 co-operating with a cam-disk 46 on the shaft 2. Coin carriers 69, 70 are mounted on spindles 73, 74 connected together by links 76, 77. A coin is inserted into each carrier, and the carriers rotated by means of a handle on the spindle 74, the coins moving the levers 59, 63 from engagement with the pins 57, 61 so as to free the ratchet 3, which is thereupon rotated by a spring 85, permitting all the pawls to drop into engagement.

Title: Improvements in or relating to a hitch
IPC: A01B23/04
Filed: 1948-02-06
Abstract: 653,745. Agricultural implements. FERGUSON, Inc., H. Feb. 6, 1948, No. 3512. Convention date, May 13, 1942. [Class 6(i)] An implement such as a harrow is attached to a tractor through the stirrup member 53 secured to the rear ends of the longitudinal members 55 carrying a cross shaft 51, which in turn carries return bars 49 pivotally attached at 49a to the links 37. In addition the frame 48 is connected to the centre of the harrow by means of a link 64 adjustable in length. Should the implement meet an obstruction the link 47 rotates the bell-crank lever 42 against the action of spring 43 to admit fluid under pressure to the cylinder 27 thereby rotating the lever 33 and lifting links 36 to raise the harrow. In another embodiment the forward end of the sub-frame 56 may be adjustable laterally of the tractor. Specification 653,746 is referred to.
Patent GB-963016-A (GB)
Title: Improvements in and relating to transverse flow type blowers
IPC: F04D17/04
Filed: 1961-01-05
Abstract: 963,016. Transverse-flow blowers. T. HELMBOLD. Jan. 5, 1961, [April 22, 1960; June 3, 1960; Nov. 19, 1960], No. 475/61. Heading F1C. A transverse-flow blower with a drum-shaped rotor is characterized in that adjacent to the rotor side of a housing part forming a partition between inlet and outlet there is arranged a substantially cylindrical body rotatable in a free or driven manner in the same direction as the rotor and having an axis parallel to the rotor. The substantially cylindrical body may be a solid body or it may be a standing vortex generated by a guiding body outside the rotor. Fig. 7 shows an arrangement of four transverseflow blower impellers 1 discharging to a common diffuser passage 20. The inlet and outlet sides of each blower are separated by a stationary partition 4 and a cylinder 5 located between the impeller 1 and the partition 4. The cylinder 5 is rotated by the fluid or is driven through gearing or the like. This use of a rotary cylinder in place of a stationary wall reduces the formation of boundary layer eddies. In the blower shown in Fig. 5, a pivotable flap 17 is located between the parts 4, 5 to afford an adjustable by-pass from the outlet 3 to the inlet 2, whereby the flow through the impeller can be increased to improve the efficiency at low throughput or during starting. A flow guide member 18 is provided. In another embodiment, the pivotable member 17 is omitted and the adjustable bypass is obtained by displacing the partition 4 relative to the cylinder 5. Fig. 4 shows a blower in which a standing vortex 5a replaces the solid cylinder. The vortex is generated and stabilized by a concave member 8. A pivotable flap similar to the flap 17 shown in Fig. 5 may be provided between the partition 4 and vortex 5a. Adjustment of the flap adapts the size and energy of the vortex 5a to the working conditions of the blower. Concave formations 11, 12, preferably forming part of the blower casing wall as shown, generate further cylindrical standing vortices (not shown), which deflect the air flow towards the casing wall to produce a diffusing effect on the flow. Also, a dragging effect is exerted on any reverse flow which may tend to occur when the blower is heavily throttled. Similar effects are produced by the provision of a cylinder 7 (Fig. 2, not shown), freely rotating or driven in a direction opposite to that of the impeller and disposed in a recess in the wall of the outlet 3.

Title: Improvements in or relating to processes for the reaction of finely-divided solid materials with a gas
Inventor: MERRE MARCEL DE
IPC: C22B1/10
Filed: 1954-01-07
Abstract: In the reaction of a gas with finely-divided solids in the fluidized state, for example the roasting of ores, cooling is effected by means of a movable cooling tube or tubes which can be immersed at varying depths in the fluidized bed.  Variations in the temperature of the fluidized bed are corrected by manual or automatic movement of the tubes; each tube or group of tubes may be independently adjustable. In the roasting of speiss containing arsenic, copper, lead, and iron to produce oxides, the temperature may be maintained between 850 DEG and 900 DEG C.  Specification 740,567 is referred to.
Patent GB-137530-A (GB)
Title: Improvements in or relating to combination locks
IPC: E05B37/08
Filed: 1920-01-06
Abstract: 137,530. Denayer, A. Sept. 19, 1917, [Convention date]. Locks, permutation.-A combination lock is set by a single knob, which by rotation in one direction relatively to a dial selects one of the combination disks to be set, and by rotation in the other direction sets that disk. Provision is made for varying the combination, and, preferably, the lock is so arranged that the movements of the bolt can only be completed after scattering the combination. The sliding bolt 2, operated by a key, or by a knob carrying a disk with pins 5, 6 engaging a rack 7 on the bolt, carries a pivoted spring-controlled lever 10, which is arrested by a lever 16 pivoted on the casing and controlled by combination disks 21, 22, 23, 34 except when notches 29 in these disks are alined below a crosspiece 31 at the end of the lever 16. When the notches are alined, the lever 16 rocks clear of the lever 10 and the bolt can be moved back, but not completely owing to a leg 83 on a spring- controlled slider 82 engaging a recess in the lever 16. Complete withdrawal of the bolt can only be effected after breaking the combination of the disks, which causes the bevel edges of the notches 29 to lift the bar 31 against the spring 33 to rock the lever 16 and allow the slider 82 to move back fully. Similarly, the bolt cannot be shot completely until the combination disks have been disarranged to rock the lever 16, so that the lug 83 can ride out of the notch on to the part 86 of the lever. The combination disks, notched for retention by a spring-pressed pawl 34, mounted in a drum 19, and spaced apart by disks 26, are adjustably connected by pawls 69, 70 controlled by a spring 72 to concentric or adjacent rings 66, through which extends a sleeve 42 carrying pivoted pawls 60 adapted to be projected radially to engage lugs 65 on the rings. The sleeve 42 is mounted in the drum and is squared at the end to carry a dial 47, behind which is arranged a clutch device for preventing contraclockwise movement. Another sleeve 41, Fig. 14, fitted on the sleeve 42 has circumferential cam-grooves 62, 63, 64 opposite the pivoted pawls, and is fixed on a spindle 40 projecting through the sleeve 42 and squared to carry the knob 48 and a wheel 49 having notches corresponding to the number of combination disks and engaged by a spring pawl carried by the sign disk 47. By means of signs on the knob and a fixed mark on the drum, the knob can be turned contra-clockwise relatively to the setting disk 47 to position the cam sleeve 41 so as to project any of the pawls on the sleeve 42 into driving engagement with the corresponding disk, rotation of the knob in a clockwise direction effecting the setting by the aid of signs on the disk 47 and a fixed mark on the casing. The disks are thus operated successively to aline the notches 29. To vary the combination, a rod 73 is inserted through apertures in the drum, and fixed disks 26 to disengage one set of pawls 70 and permit relative adjustment of the disk and its ring.

Patent GB-346430-A (GB)
Title: Methods of making and treating cellulose esters and products thus obtained
IPC: C08B3/22
Filed: 1930-01-08
Abstract: According to the parent Specification, cellulose acetate is prepared in a light, loose or fluffy form by acetylating cellulose in the presence of liquid sulphur dioxide, and discharging the acetylation solution from the reaction vessel in such a manner that the sulphur dioxide is abruptly gasified.  This method is now extended to the preparation of other organic cellulose esters, or of previously prepared cellulose acetate, in a light, loose or fluffy form.  Thus, cellulose or its conversion products may be acylated (otherwise than by acetylation) in the presence of liquid sulphur dioxide, and the ester precipitated as described in the parent Specification, or cellulose acetate or other organic ester of cellulose, prepared otherwise than in the presence of liquid sulphur dioxide, may be dissolved or dispersed in liquid <PICT:0346430/IV/1> sulphur dioxide, and the ester precipitated as described in the parent Specification. As described in Specification 329,718, [Class 2 (ii), Cellulose &c.], in connection with cellulose acetate, the esters may be hydrated while dissolved or dispersed in the liquid sulphur dioxide, As shown, a mixture of wood cellulose, propionic or benzoic anhydride, liquid sulphur dioxide, and a little sulphuric acid or zinc chloride is introduced into a vessel 3 having a tight cover 4, and is maintained at 20-40 DEG  C. and corresponding pressure until the desired degree of acylation is reached.  The reaction product is then mixed with a hydrating agent, e.g. water, dilute alcohol, or dilute acetic or dilute sulphuric acid, and transferred through a pipe 19 to a closed pressure vessel 18.  When the hydration has proceeded to the desired stage, the product is discharged through a pipe 7 into a vessel 10 which contains water, carbon tetrachloride, benzene, toluene or other precipitant, and has heating means 16, a steam supply pipe 17, an outlet 11 for gaseous sulphur dioxide, and a hinged bottom 13.  The pressure in the vessel 10 may be atmospheric or less, or somewhat above atmospheric.  Apparatus from which the vessel 18 is omitted is also described, and the use of acid halides, or mixtures of acid halides and anhydrides, as acylating agents is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) includes an example in which cellulose 100, acetic anhydride 260, liquid sulphur dioxide 1000, and sulphuric acid 3 parts are digested and stirred in the vessel 3 at 20-30 DEG  C. and corresponding pressure until the reaction has proceeded to the desired degree.  This subject-matter does not appear in the Specification as accepted.
