Title: Improvements in or relating to joy sticks for helicopters
IPC: B64C1/00
Filed: 1922-04-12
Abstract: 178,452. Pateras Pescara, Raul, Marquis of. April 12, 1921, [Convention date]. Screw propellers. - A helicopter is provided with means for feathering the propeller blades, to decentralize the thrust in any direction, operated by a single hand lever which also operates adjustable surfaces for controlling the lateral and longitudinal balance during horizontal flight, means also being provided for cutting out the propeller control. Fig. 1 shows a tubular lever 21 connected to a fixed post 23 by a card an joint having centre at 24. A ring 39 is mounted on a spherical bearing 38 in the plane of the cardan joint, and is normally engaged by a bell 34 on the lever 21 so as to move therewith. Four equidistant cleats are provided on the ring 39, as represented in Fig. 4 at 51, which are connected by the system of cords shown to the inner rings of two ball races 57, 58 mounted on gimbals in the planes of the propellers in such a manner that the rings 57, 58 always remain parallel to the ring 39. The outer rings of the ball races 57, 58 are connected as shown in one instance at 63 to cords 64 which pass over pulleys 67, 69 and 68, 70 to opposite ends of a strut 73 connecting the upper and lower blades of a biplane type of propeller. A strut 74 connects the pulleys 69, 70. When the ball races 57, 58 are tilted, the cords 64 cause a cyclic variation in the incidence of the blades of both propellers and the thrust is correspondingly displaced. The lever 21 has a handle 25 which can be rotated about the axis of the lever to turn a shaft 28. The shaft 28 has two screwed portions 29, 30 connected by a cardan joint centred at 24. A nut 32 on the screw 29 is connected by screws 33, passing through slots in the tubular lever 21, to the bell 34, so that the bell can be raised out of contact with the ring 39 to leave it free from the lever 21. Simultaneously, a nut 35 on the screw 30 raises a bell 37 on the pillar 23 until the bell contacts with the under surface of the ring 39 and holds it stationary. Movement of the lever under these circumstances controls only the surfaces 75, 76. Specification 171,711 is referred to.

Patent GB-442636-A (GB)
Title: Improved mechanism for forwarding loaves or similar articles, particularly for the slicing of said articles
IPC: B26D7/06
Filed: 1935-04-05
Abstract: 442,636. Endless chain conveyers. AMERICAN MACHINE & FOUNDRY CO., 511, 5th Avenue, New York, U.S.A. April 5, 1935, No. 10626. Convention date, Nov. 9, 1934. [Class 78 (i)] Articles such as loaves are forwarded to a slicing-machine by means having successive cycles of advancing movement during each of which it advances an article first at a relatively high speed and then at a relatively low speed, the article being moved through the slicing mechanism at the lower speed. The leading loaf L of the row in the shoot 10 is arrested temporarily by fingers 17 which are lowered by the rotation of a cam 19 to permit the loaf to slide along the shoot into the path of one of a series of pushers 28 mounted on a pair of parallel endless chains 29. The shaft 32, Fig. 2, of the driving sprockets 30 of the chains 29 carries a ratchet wheel 46, the teeth 45, 45<a> of which are engaged by pawls 44, 47, respectively. The pawl 44 is pivoted to an arm 42 of a segmental gear 41 which is mounted loosely on the shaft 32 and engaged by a segmental gear 40 carried by a pivoted member 39. A link 38 connects the member 39 to a block secured adjustably in a slot in an arm 37 which is integral with a roller carrying pivoted arm 36. The roller 35 on this arm is received in a cam groove formed in one face of a rotary member 34. The other face of the member 34 also is formed with a groove which receives a roller 48 on an arm 49 which is connected by similar mechanism to the pawl 47, the arrangement being such that the pawl 47 is moved at a much lower speed than the pawl 44. The amplitude of movement of the driving members 39, 52 may be varied by adjusting the position of the blocks in the links 38, 50 when loaves of different size are to be dealt with. After being sliced the loaves pass on to a table 68 provided with adjustable side guides 68<a> for holding the slices together, and are advanced by pushers 74 on a conveyer 73 to an endless push-plate type conveyer 76 for delivery to the wrapping machine. The table 68 and framework 71 of the conveyer 73 can be turned about an axis 80, and held in adjusted position by a stud and lock nut 84.

Title: Improvements in the treatment of textile and other materials made of or containing cellulose esters
IPC: D06M11/38

Abstract: 309,377. British Celanese, Ltd., (Assignees of Dreyfus, C.). April 7, 1928, [Convention date]. Addition to 304,596. Yarns &c., treating with liquids, gases, and vapours.-The process for raising the safe ironing- temperature of textile and other materials made of or containing cellulose acetate or other organic acid esters of cellulose as described in the parent Specification, in which process the fabric &c. is partly saponified by means of an alkali solution having an hydroxyl-ion concentration insufficient to cause irregular saponification, addition of further quantities of alkali in order to maintain the concentration during the treatment is obviated by the use, at the commencement, of a quantity of alkali solution greater than 120 times the weight of the materials to be treated, for instance, 130-160 times such weight. Alkali solutions of 0.3-0.7 per cent are suitable, for example, there may be used an amount of alkali corresponding to 4-8 per cent of the weight of the material. The addition of soap to the saponification bath is advantageous. The treatment may be carried out at 60-90‹ C., for example, at 70-80‹ C. For operating the present process and also that of the parent Specification, it is an advantages to add to the alkali solution a buffer salt such as sodium or potassium acetate, or borax; in such cases the concentration of the alkali may be reduced. The treatment may be applied to mixed materials containing natural and other artificial fibres. When applied to materials containing natural silk, the latter may be degummed during the saponification treatment. The Specification as open to inspection under Sect. 91 (3) (a) refers to the use of caustic nitrate solutions of up to one per cent concentration. This subject-matter does not appear in the Specification as accepted.

Abstract: 478,621. Photographic roll-film cameras. ZEISS IKON AKT.-GES. April 16, 1937, No. 10943. Convention date, April 28, 1936. [Class 98 (i)] In a camera having a reflex finder chamber above the exposure chamber, a rotatable member which operates both the shutter-winding and filmwinding mechanisms, or a ring connected to said member, is mounted coaxially with the finder objective. The member may also actuate a counting mechanism. As shown, a shutter-winding and film-winding lever 5, fast with a ring 4 turning on the mount of the finder lens 3, carries a pawl 6, Fig. 1, which is caused by a fixed guide-slot 7 to displace a member 8 operating the winding mechanism of the shutter 9 when the lever 5 is depressed. Simultaneously, a toothed segment 12, Fig. 2, on the ring 4, turns a wheel 13 which through gears 14, 15 rotates a sprocket roller 16 serving to advance the film from the supply spool 19 to the take-up spool 20 ; and a pawl 21, also carried by the ring 4, first rides along a fixed guide 24 and then drops into engagement with a toothed exposure-counting disc 22 pushing it round to display the next number in a window 23. The lever 5 is returned by a spring 10; and reverse rotation of the roller 16 is prevented by a ratchet 17 and free-wheel device 18. The shutter release knob 11 is mounted adjacent to the lever 5.

The pile shown consists of a body 1 of wood or a reinforced concrete with a central bore 2 opening into a recess 3, beneath which is a foot of truncated pyramidal form made up of four sections 4 each pivoted to a ring 8 in a recess formed in the lower ends of the sections. Beneath this is a shoe 10 forming the lower end of a cage 11 enclosing and supporting the sections 4. This pile is driven to a certain depth, and a steel rod is inserted in the bore 2, its lower end resting on the head of a pin 9 placed between the four sections 4. The rod is then driven down, forcing down the shoe 10 and cage 11, and causing the taper head of the pin 9 to engage with the ring 8, and to splay the sections 4. Driving then proceeds until the sections 4 are horizontal ; the foot is then grouted with, and the bore filled up with, concrete.
