Filed: 1938-05-24
Abstract: 513,755. Photographic cameras. KODAK, Ltd. May 24, 1938, No. 15525. Convention date, May 29, 1937. [Class 98 (i)] A camera includes separate manually operable handles for winding mechanism feeding the film to the take-up spool and for mechanism for rewinding the film, and means connecting the mechanisms for automatically disconnecting one mechanism from its spool as the other mechanism is brought into operative engagement with its spool by actuation of the rewinding handle. As shown, the winding handle 15 drives through a ratchet 16, 17 a gear 19 meshing with a gear 20 on a shaft 21 which drives the take-up spool through gears 22, 23: and a clutch 30, 31, the clutch element 30 being mounted on a shaft movable axially of the spool carrying an annular grooved member 32. The shaft 21 drives a coaxial sleeve 25 carrying feed sprockets 28, 29 through a clutch 26, 27 the clutch member 26 on the shaft 21 having a grooved member 37. The supply spool 10, which may be enclosed in a casette 13, Fig. 3, has a clutch arrangement comprising a transverse rod to engage a notched tubular member 42 which can be raised into engagement therewith by rewinding handle 51 pivoted at 52 and having a cam surface 50 adapted to raise the member 42 against the action of a spring 60 when the handle 51 is pivoted away from :the casing. A grooved member 44 on the member 42 engages one end 45 of a pivoted lever 34 the other end 33 of which engages the member.32 and has lug 36 engaging the member 37. In the position shown in Fig. 1, the clutch 40, 42 is disengaged and this supply spool rotates freely to allow film to be fed by,the sprockets to the take-up spool. For rewinding, the handle 51 is raised thus engaging the clutch 40, 42 and causing the lever 34 to pivot to disengage the clutch 26, 27 and 30, 31, thus freeing the supply spool and sprocket from , its driving mechanism and allowing film to be rewound by the handle 51.

Abstract: 1411517 Continuous moulding of foamed webs VITA INTERNATIONAL Ltd 29 April 1974 [31 March 1973] 15617/73 Heading B5A [Also in Division C3] A method of obviating dome formation during the continuous casting of foamed plastics slabstock comprises diverting a part of the foaming mass, whilst it is still mobile, towards the sidewalls 11 of the moulding trough by means of a shaped element 15 positioned on the base of the moulding unit. As shown in Fig. 2, the diverting element comprises a platform having a flat surface 16 parallel to the base 10 of the moulding trough, and, downstream of this, an inclined portion having ramps 18, 19 inclined transversely of the trough and a region 17 inclined in the longitudinal direction of the trough. The carrier web 13 passes over the diverting element, liquid foamable mixture being deposited on the web as it passes over the surface 16. The position of the diverting element is adjusted so that the foamable mixture is still mobile when it reaches the downstream edge 20 of the element, thus preventing cavity formation in the slab. The diverting element may be split longitudinally to enable its width to be adjusted. By the method of the invention, the effects of surface tension and temperature gradient within the block are reduced so that a substantially flat block is produced. If necessary, any high regions at the sides of the slab may be reduced by pressure rollers 21, as shown in Fig. 3.

Abstract: 1,030,225. Waveguide dissipative loads. FERRANTI Ltd. April 22, 1963 [April 25, 1962], No. 15703/62. Heading H1W. A dissipative waveguide load comprises a short-circuited length of waveguide made of a resistive ferromagnetic material having a Curie temperature low enough to be reached during normal operation of the load. A suitable material, is 42% nickel iron having a Curie point of 360‹ C. The load may take the form of two flat coils of rectangular waveguide mounted side-byside with their inner ends joined and their outer ends providing respectively a short-circuit and an input coupling means. Radiating fins may be provided. Wave energy entering the load is dissipated at first mostly in the region of the input coupling, but as the temperature rises and the Curie point is reached, the attenuation in this part of the load decreases. Thus the region providing attenuation gradually advances along the guide.

Title: A method of treating meat
IPC: A23L13/70
Filed: 1966-04-12
Abstract: The quality of meat and meat products is improved by treating them with one or more basic amino acids or salts thereof, exemplified by arginine, arginine glutamate, histidine, histidine hydrochloride, lysine and ornithine.  The amino acid or salt is added to raw or partially processed horse-flesh, beaf, mutton, pork, chicken, cuttle fish, tuna, mackerel, or whale meat salted with red pepper, in an amount of at least 0.02%, preferably between 0.3-1.5%, based on the weight of the raw meat.  The treatment is applied by dipping the meat in a solution of the amino acid, by spraying thin slices of the meat with a solution or powder of the amino acid, by injecting a solution of the amino acid into the meat, by smearing the surface of the meat with the amino acid or by admixing the amino acid with the meat in a divided state.  The treated meat may be formed into a paste, a sausage product or a canned product such as corned beef or press ham. In the Examples, the quality of treated meat or meat product is evaluated in terms of the colour of the fresh meat and the palatability and degree of shrinkage after cocking.  Certain examples disclose the treatment of the following meat mixtures: (5) minced pork meat, salt, sugar, sage, pepper and mace; (6) chopped beef, ice water, salt, sugar, pepper, coriander, mace and sodium ascorbate to which mixture there was subsequently added chopped pork meat, sodium nitrate and sodium nitrite; (8) tuna fish, lard, salt, sodium nitrite and sodium ascorbate; (10) shoulder of pork, minced pork fat, salt, sodium nitrate, wheat starch, sugar, spice and L-glutamic acid; (11) whale meat with a seasoning consisting of soy sauce and sugar; (12) beef, sodium nitrate, sodium nitrite, sodium chloride, sugar, pepper, sage, sodium ascorbate and water to which mixture there was subsequently added lard seasoned with sodium glutamate and salt, for the production of corned beef.  Certain of these mixtures were stuffed into natural or vinylidene casings to produce sausages.

The heating is preferably carried out in the presence of a copper compound or copper and at a temperature in the range of 200-300 DEG C. In an example benzene-m-disulphonyl chloride, p-dibromobenzene and copper phthalocyanine were boiled under reflux at a temperature of 218-219 DEG C.  Hydrogen chloride and sulphur dioxide were removed as by-products and 2,5,211,511-tetrabromo-m-terphenyl recovered. In another example 2,4,6,211,411,611-hexachloro-m-terphenyl was obtained from benzene-m-disulphonyl chloride, and 1,3,5-trichlorobenzene in the presence of cuprous chloride by a similar process.
