IPC: A63H33/04
Filed: 1928-05-15
Abstract: 291,095. Gilbert Co., A. C., (Assignees of Anketell, E. N.). May 27, 1927, [Convention date]. Model machines; mechanical constructions, details for building up.-A toy hoisting mechanism comprises a plurality of winding-drums mounted between detachably - connected, perforated, flanged side-members, one drum being driven from a source of power and capable of being connected to or disconnected from the other drum so that the drums may be jointly or individually rotated. As shown in Figs. 1 and 3, the hoisting mechanism comprises three drums 20, 26, 32 each secured to a shaft rotatable within Holes 18 in side members 10 having perforated flanges 12. The device may be bolted to a perforated base plate 16 in any desired position. The foremost drum 20 is rotated by a crank 23 to raise or lower the jib 71, and may be locked in position by a pivoted pawl 25 engaging a gear-wheel 24. The intermediate drum 26 is connected by a cord 84 to the framework of a grab 70, while the rearmost drum 32 controls the opening and closing of the grab through a cord 82. The drum 32 is driven by a reversible electric motor 52 through a worm 50 and gear train 49, 47, 46, 45, 34. The drum 26 is normally held stationary by a brake 31, but rotates with the drum 32 when a pinion 35 meshing with the wheel 34 is moved into gear with a wheel 29 upon the operation of a control lever 38. In a modification the mechanism may be driven by hand, the shaft 36 of the pinion 35 being provided for the purpose with a crank handle. As shown in Fig. 9, the invention is applied to a slewing crane, the mast 105 and jib 100 being supported by a pivoted base plate of channel section. Specification 284,328 is referred to.
Patent GB-851278-A (GB)
Title: Coin collectors for telecommunication services
Inventor: HALL FREDERICK WILLIAM
IPC: H04M17/02
Filed: 1958-05-05
Abstract: 851,278. Coin-freed telephone apparatus. ASSOCIATED AUTOMATION Ltd. May 5, 1959 [May 5, 1958], No. 14279/58. Class 27 A coin collector for an automatic telephone or other telecommunication service of the postpayment type has means, such as a weight or a spring within a barrel 8, for operating a pulsing switch 10B by which signals are transmitted to the exchange in accordance with the value or number of coins inserted; insertion of a coin depresses a lever 2A and moves a link 3 to load the spring or weight and, after the coin has been tested in a device 5, it falls down a shoot 5C to depress an escapement lever 7 which releases the loaded spring or weight. When the connection with the called party has been established, a magnet 6 is energized and withdraws a member 6E from blocking engagement with the link 3 so that insertion of a coin, such as a threepenny piece, will move the link and cause a ratchet 4A to load the spring, a check pawl 4B preventing unwinding of the spring. The spring is connected at one end to a main gear wheel meshing with a gear 9A on a shaft 10 which carries a cam 10A for operating the pulsing switch 10B but drive is prevented by an arm 11 on the shaft 10 engaging a barrel 12 on the escapement lever 7 until the lever is depressed by the falling coin, thus allowing the arm to pass through a cut-out 12B and rotate through one revolution to its initial position. A centrifugal governor 9E controls the speed of the pulsing shaft 10. Coins can be inserted in succession to give cumulative loading of the spring until a slip comes into action to prevent overloading. Several coin slots may be provided, with means, such as selectable gearing, for ensuring that the pulsing shaft rotates a number of times corresponding to the different coin values and for ensuring that coins cannot be inserted in two slots at the same time. The collector may be arranged to require an initial fee for the use of the dial or of the telephone kiosk, the prepaid coin being held in suspense until the connection is established or not established, when the coin will be refunded on replacement of the handset or receipt of a line signal. Specifications 810,351 and 828,265 are referred to.

Title: Improvements in control valves for pressure systems
IPC: G05D16/06
Filed: 1933-05-19
Abstract: 405,506. Valves. WORK, E. W., 144, Albany Avenue, Toronto, Canada. May 19, 1933, No. 14508. [Class 135.] A control valve for maintaining the pressure in a water system between maximum and minimum predetermined limits has an outlet 2, connected to the water system, and an inlet 3 closed by a valve 18 slidable in a cylindrical member 14 secured to a flexible diaphragm 12. The latter carries a seating 13 for a valve 19 guided by the cylinder 14, and is under the action of a spring 30 which is adjustable by screw 32. The valve 19 carries a projection 23 upon which rests a distance piece 33 adapted to contact an adjustable stop 34. In operation, pressure water passes from the inlet 3 past the valve 18 to the outlet 2 to the water system. When the minimum pressure in the system is reached, the valve 18 closes. Should the pressure in the system increase, the diaphragm 12 flexes and compresses a spring 25 to hold the valve 18 closed. When the water pressure has reached a maximum value, the distance piece 33 engages the stop 34, and further deflection of the diaphragm carries the valve seat 13 away from the valve 19 and water flows from the system through the valve 19 to the discharge port 4.
Patent GB-981976-A (GB)
Title: Process for the permanent shaping of fibrous material containing or consisting of keratin and fibrous material which has been treated by this process
Inventor: MERTENS HEINRICH
IPC: D06M13/325
Filed: 1963-04-11
Abstract: Fibrous materials consisting of or containing keratinous fibres are permanently shaped by impregnating them with a solution or dispersion of a secondary or tertiary amine which is volatile in steam only to a negligible extent and then heating them with steam during shaping. Suitable amines are dihexylamine, methyloctylamine, tripentylamine, dimethylstearylamine, diethyl-palm kernel fatty amine N-methyltaurine the ammonium salt of dimethylamino acetic acid, b  (dimethylamino) ethane sulphonic acid sodium salt, the ammonium or sodium salt of N, N diethylglycocoll, diethanolamine, butyl diethanolamine, triethanolamine, penta-(2-hydroxyethyl) diethylene triamine, penta-(2-hydroxypropyl) diethylene triamine and penta-(2-hydroxypropyl) dipropylene triamine.  The amine maybe applied to the materials as an aqueas solution or dispersion or as a solution in a volatile organic solvent, e.g. a low molecular weight alcohol, ketone or ester, by immersion or spraying in an amount of 0.2-5% by weight based on the materials.  The amine may be neutralised with an organic acid, e.g. formic or acetic acid, either in the treatment liquor or on the fibrous material.  The treating composition may also contain a non-ionic wetting agent and a reducing agent, e.g. an alkali metal bisulphite, sulphite, thio sulphate or dithianite or an alkali metal salt of a hydroxy alkane sulphuric acid or a reaction product thereof with ammonia or a primary amine.  After impregnation and drying the materials may be stored and made up into garments prior to shaping.  Shaping may be carried out at temperatures of 100 DEG -150 DEG C. using smooth or textured rollers, dies, crimping devices or a flat iron to provide calendered, embossed, crimped and pleated or creased effects.  The process may be combined with a shrink-resist finish using oxidising agents, e.g. dichlorocyanuric acid and its salts.  Yarns and woven, knitted and non-woven fabrics comprising wool alone or an admixture with cotton or polyester fibres may be treated. Specification 891,217 is referred to.

Title: Improvements in or relating to cinematographic apparatus
IPC: G03B21/40
Filed: 1964-04-08
Abstract: 1,041,131. Cine apparatus. KEYSTONE CAMERA CO., Inc. April 8, 1964 [April 19, 1963], No. 14517/64. Heading G2E. An intermittent claw feed operates at slow motion speeds independently of the speed of the disc shutter 18, so that flicker and loss of transmitted light are avoided. Disc 18 is mounted on shaft 20 carrying a cam 22 whose surfaces are engaged by follower 36 mounted on the claw arm 24 which thereby receives its film feeding motion in synchronism with the apertures in the shutter. Arm 24 pivots about shaft 42 and about the off-set portion 44 in a vertical plane, spring 40 biasing the arm towards cam 22. A variable speed electric motor drives disc 18 through a shaft and belt 16, and worm 50 on shaft 20 drives, through gear trains, the continuous film drive mechanism including upper and lower sprocket shafts 52, 54 which are connected by belt 56. Worm 50 also drives cam 62 whose crests 64, 66 rock a cam follower link 70 pivoting on shaft 72. An adjustable stop member 76 on a leg link 70 engages the spring- loaded shaft 42 carrying claw arm 24, while a further arm on the link has a stop member 80 engaging a guide surface 81 of another link element 82 pivoting at 84. Over-centre spring 86 biases link 82 in either of two positions which are manually set using tab 98 and push-bar 92. With links 70, 82 in the full-line position of Fig. 7, follower 74 does not engage cam 62 with pivot structure 42 in the position of Fig. 5, claw 26 operates through apertures 27 to drive the film. With the links in the broken line position stop 80 rides down surface 81 and follower 74 then engages cam 62 so that pivot 42 is moved to the left twice in each revolution of the cam to remove claw 26 from driving operation with the film. Since cam 62 rotates at one sixth the speed of shaft 20 the film feed is thereby reduced to one-third its normal speed. For slow motion operation gear 104 is moved by control link 100 to engage sprocket drive gear 106 which may be driven by a nylon gear 154 which in turn is driven through a clutch disc 156.

Title: A new or improved means for indicating weighments
IPC: G01G1/00
Filed: 1922-05-26
Abstract: 202,090. Pooley & Son, Ltd., H., and Dobson, J. May 26, 1922. Indicating-mechanism; pendulum-weight apparatus. - In an indicating-mechanism for a weighing-apparatus, a weight resistant automatically positions a member in the path of a traversable weight-indicating mechanism, the said member automatically freeing the traversable mechanism on the application of a load to the apparatus. As applied to a platform weighing-machine, the load on the platform pulls down a draw-rod 4 coupled to a pendulum resistant 9 damped by a dash-pot 10. A vertical arm 11 secured to the pendulum moves a bar 12 having at one end a protecting tooth 14 resting upon a track 13. The protecting tooth liberates a toothed wheel 15 forming part of the traversable weight-indicating mechanism 16, which then moves along guiderods 17 under the propelling action of a weight 34, drum 31, and flexible band 27. The drum 31 is connected by gearing with the toothed wheel 15 which drives a totalizing mechanism 26 until the movement is arrested by re-engagement of the toothed wheel with the protecting tooth 14. To compensate for the unequal movements of the pendulum 9 for equal increments of load, the flexible band 27 is attached to a lever 28 bearing on a curved surface 40. The mechanism 16 is returned after removal of the load, by means of a flexible band 36, weight 35, and handle 39, or the return may be effected automatically by electrical means. By an arrangement of an electric circuit through a lamp the numerals on the totalizing- mechanism may be visible only when the travelling mechanism 16 is stationary.
