Title: Track-type vehicle including a steering clutch
IPC: B62D11/08
Filed: 1973-08-31
Abstract: 1439873 Steering endless track vehicles CATERPILLAR TRACTOR CO 31 Aug 1973 [1 Sept 1972] 41099/73 Heading B7B [Also in Division F2] A steering clutch 50 for selectively discontinuing power transmission to a track of a track laying vehicle includes a yoke 46 connected to the clutch and movable between first and second positions to cause the engagement and disengagement of the clutch, the yoke being moved to disengage the clutch by a fluid motor 34 and a push rod 42, the rod having spherical end nuts which respectively seat in sockets 198, 194 in the yoke and actuating device. The fluid motor 34 is mounted by a flange 180 to an externally accessible part of the vehicle for ease of access. A plurality of driving clutch discs 150 are engaged by a driving drum 146 and are interleaved with driven discs 152 which engage the driven drum 70. The discs are normally held in engagement by springs 153 which act between the driving drum and a stop 154 to urge studs 156 and a plate assembly 158 to the right. The plate assembly is connected via a cage 174 to trunnions 172 of the yoke which is pivoted to the vehicle frame at 48. On extension of the push rod by the fluid motor the yoke is moved to disengage the clutch by moving the plate assembly against the action of the springs 153. The length of the push rod is adjustable and an adjustable screw stop 212 is provided on the yoke. Fluid supply to the motor 34 is controlled by a valve 28 which is actuated by a pedal 16. The valve is fixed to a plate 24 pivoted on the pedal pivot 22 so that after actuation of the valve by the pedal contacting plunger 32, continued pedal movement pivots the valve and plate 24. This causes a link system 56, 58, 60, 62, 64 to tighten a brake belt 68 about the driven drum 70, and the resulting differential braking aids the action of the steering clutch.

Title: Switch operating mechanism
Inventor: WOODCOCK RAYMOND
IPC: H01P1/12
Filed: 1959-12-07
Abstract: 895,758. Waveguide switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 28, 1960 [Dec. 7, 1959], No, 41520/59. Class 40(8). A switch comprises independently movable control and actuating members coupled by a spring, the actuating member being lockable in two alternative switching positions and the arrangement of the parts being such that when the control member is moved to release one of the locks, the spring is stressed to an extent sufficient to cause the actuating member to move to the other position upon release. In the waveguide switch shown, a rotor 9 contains a waveguide passage 7 disposed to connect either of waveguide terminals 5, 6 to terminal 4 in the extreme positions of the rotor. In these positions the rotor is locked by either of two pawls 12 which are fixed on the stator 1 and engage teeth 14 on the rotor. The rotor is connected by a coil spring 11 to an independently rotatable control member 10, the connection being such that, with the handle 18 of the control member held in the central position shown, the rotor would normally take up an equilibrium position with the teeth 14 equidistant from their corresponding pawls 12. As shown, the rotor is locked in an extreme position with a certain amount of energy stored in the spring. To switch to the other position, the handle 18 is moved in the direction of intended movement of the rotor until an arm 16 releases the operative pawl. This movement increases the amount of energy stored in the spring, the increased energy being sufficient to ensure that, despite friction losses, the rotor rotates until it reaches its other extreme position where it is locked by the other pawl.

Title: Improvements in photographic material, processes for preparing such material and processes for preparing photographic records
Inventor: JR RIENZI BELCHER PARKER
Filed: 1959-12-11
Abstract: 877,842. Photographic vesicular materials. KALVAR CORPORATION. Dec. 11, 1959, No. 42300/59. Drawings to Specification. Class 98(2) A film of normally hydrophilic colloid containing a photolytic compound capable of forming light-scattering centres on exposure and development contains also a chrome carboxylic acid complex of Werner type. Records made therefrom by exposure and heat-development show improved durability resulting, it is believed, from a curing effect of the complex on the colloid. Preferably, a proportion of partially condensed urea-formaldehyde resin is included in the hydrophilic colloid. Seven examples use p-dimethylamino-benzene-diazonium zinc chloride as photolytic compound, thus in Example 1 gelatin solution is adjusted to pH 2.5, glycerine, the diazo sensitizer and stearato chromic chloride dissolved in isopropanol are added and the solution coated on cellulose acetate film and dried; and the film may be used for making original records or for contact or projection copying, for instance contact copying of microfilm records; and developed by heating for 3 or 4 seconds preferably with a further exposure after cooling and storage for an hour to allow escape of gas released in the re-exposure. Examples II, III and IV are similar, describing only the addition of urea-formaldehyde resin, the omission of glycerin and the addition of colloidal silica to the solution of Example I. Example V uses polyvinyl alcohol as colloid, Example VI laurylato or propionato chromic chloride in place of the stearato compound; and Example VII is directed to a comparison in which chrome alum replaces the Werner complex and also one in which urea -formaldehyde is used without such complex. Other diazo compounds and supports for the sensitive films are referred to, and the use of ferric ammonium citrate as photolytic compound is indicated.

Abstract: 991,156. Spinning viscose. ONDERZOEKINGSINSTITUUT RESEARCH N.V. Oct. 28, 1963 [Oct. 30, 1962], No. 42342/63. Heading B5B. Regenerated cellulose filaments having an all-skin structure are made by extruding viscose, in the presence of at least one regeneration retardant, into a spinning bath containing sulphuric acid, sodium sulphate and 3-10% by weight of zinc sulphate, stretching the freshlyspun filaments (e.g. 90-100%) in a sulphuric acid bath containing 1.5-10% by weight of acid and maintained at a temperature of 85- 98‹ C., adjusting the pH of the running wet filaments to 5-8.5, collecting the stretched filaments into yarn packages and drying the filaments for not more than 20 minutes. The pH may be adjusted by washing with water or with an aqueous solution of sodium carbonate, bicarbonate or sulphate, or aqueous ammonia. pH adjustment may be carried out by passing the filaments through a bath before collection or by spraying the treating liquid on to a roller over which the filaments pass before collection. The treated filaments are collected on a spool, or in a spinning pot or perforated basket. The filament may be dried by placing the yarn package in a high-frequency electric field or by unwinding the collected filaments and passing them through an air tunnel or over a heated roll. The filaments may be under tension while drying, or may be subjected to further stretch e.g. 10% and then dried. The regeneration retardant, which may be present in the viscose, or in the spinning bath, or in both, may be an amine, a quaternary ammonium compound, a carbaminate, a polyethylene glycol, or an ether of formula RO(CH 2 CH 2 O) n R<SP>1</SP>, where R is alkyl or aryl and R<SP>1</SP> is hydrogen, alkyl or aryl. Preferably the viscose also contains a cation-active nitrogen compound which counteracts fouling of the spinneret orifices. Such compounds may have formula where R is an aliphatic chain of 8-24 carbon atoms, and + y = 5-25, neither being o. The viscose preferably contains at least 0.5% of each of the regeneration retardant and the nitrogen compound. The latter may also be incorporated into the spinning bath.
