Title: Improvements in or relating to straight-bar knitting machines
Inventor: WEST ERNEST
IPC: D04B15/66
Filed: 1961-09-27
Abstract: 951,134. Knitting-machines. S. A. MONK (SUTTON IN ASHFIELD) Ltd. Nov. 29,1962 [Sept. 27, 1961], No. 34558/61. Heading D1C. In a control mechanism for a straight bar knitting machine a switch A is.closed by a pin on a reciprocating slide passing through a hole in a perforated band (not shown) the control circuit being such that when A .is closed a relay C is energized which closes a switch G so that C remains energized when A is reopened, C also closes a switch H and energizes a relay J to move a bluff K to put the perforated strip racking mechanism out of action. The relay C also closes a switch L causing a coil M to return a revolution counter to zero from a pre-set number one integer per camshaft revolution by the action of a cam on the main camshaft which closes a switch N. On reaching zero the revolution counter-closes a switch O and energizes a relay P which opens a switch Q and de-energizes the relay C. The energization of P also closes a switch R in the circuit of the reset coil S of the coil M. When T is closed by a cam on the main cam-shaft a condenser U is charged. When T is opened again the condenser U discharges through and operates the reset coil S, opening the switch O to cut out the relay P and close Q to.reset the mechanism. Specification 937,997 is referred to.

Title: Method of producing synthetic sausage casings
IPC: A22C13/00
Filed: 1954-12-03
Abstract: In the method of producing non-fibrous seamless sausage casings from viscose, or other solution of a cellulose derivative capable of conversion into regenerated cellulose, by extruding the solution through an annular die into a coagulating bath to form a continuous tubular film, vegetable and/or animal proteins of particle diameter not exceeding 0.1 mm. and in a proportion not exceeding 50 per cent by weight (based on cellulose) are added to the cellulosic solution. The casing may be treated with a protein-hardening agent such as formaldehyde, e.g. by adding the latter to the softener bath.  The protein may be gelatine, blood plasma, casein or soya bean flour.  In an example, there is dispersed in a solution of 17 per cent of nitrocellulose of 12 per cent nitrogen content in a 25/75 volume/volume ether-alcohol mixture 2 per cent of powdered gelatine passing a 0.1 mm. mesh screen, and the dispersion is extruded into a coagulating bath consisting of 5 per cent ethyl ether, 15 per cent ethyl alcohol and 80 per cent water to form a tubular film, which is then denitrated with a 5 per cent solution of sodium hydrosulphide and washed.  The film is passed through a 20 per cent aqueous solution of glycerine containing 7 per cent of formaldehyde, and dried.  In a second example, the casing is formed from viscose to which one per cent of finely divided gelatine has been added.  The casings are "prick-proof" and are suitable for the preparation of scalded and long-keeping sausages.

Abstract: 411,822. Preserving citrus fruit juices. CALIFORNIA FRUIT GROWERS EXCHANGE, 607, South Hill Street, Los Angeles, U.S.A. Dec. 12, 1932, No. 35183. Convention date, Dec. 12, 1931. [Class 49.] Concentrated or unconcentrated citrus fruit juices are preserved by heating rapidly, e.g. within not more than 2 minutes, to about 75-93‹ C. maintaining at this temperature for sufficient time, generally not exceeding 3 minutes, to render the enzymes inactive and then rapidly cooling to below 45‹ C. Examples are given of the temperatures and times of treatment employed for orange, lemon, mixed orange and lemon, and citrus fruit juices. The more acid juices require lower temperatures and shorter times of treatment, and acid may be added to the juice, e.g. to orange juice, to improve it in this respect. The juice may be supplied through a pipe 12 to a vessel 10 having an agitator 11 and connected through a pipe 13 to vacuum for deaerating the juice. The deaerated juice is fed by a pump 15 to a heater 16 where it is subjected to the heat treatment and from which it may pass to a vessel 25 where it is concentrated under vacuum at 35-45‹ C., a condenser 26 being provided. Alternatively the juice may pass from heater 16 to a cooler 23 where it is brought rapidly to low, e.g. freezing temperature by brine or other refrigerant, and the semi-frozen juice may be placed in containers and frozen hard for storage, the solids being thereby maintained in suspension during the freezing. The heater 16 consists of a tube 18 through which the juice is passed having a tube 19 centrally disposed therein and a conduit 20 surrounding it through both of which heating medium is passed. Spiral vanes may be placed in the juice space to give more uniform flow and more effective heat exchange. The cooler 23 is similarly constructed.

Abstract: 1369325 Pushbutton tuning arrangements MOTOROLA Inc 1 Aug 1972 [19 Aug 1971] 35926/72 Heading H3Q In a dual band radio receiver having a plurality of memory tabs 50 one of which is associated with each of a plurality of pushbuttons 16, the memory tabs 50 are pivotally mounted on a wave band selector 28 and each tab has a pair of projections 44, 46 with a recess 48 between them, a finger member 60 extends from an actuating member 58 attached to each pushbutton 16 for engaging the memory tab and being received in the recess 48 on withdrawal of the pushbutton, the memory tabs 50 are movable to either of a first or a second position on withdrawal of the pushbutton in accordance with movenient of the waveband selector 28 to a predetermined waveband position and a guide member 56 on each pushbutton engages with an associated memory tab to shift the waveband selector 28, on inward movement of the pushbutton, to a corresponding preselected waveband position. As shown in Fig. 2 with the pushbutton 16 in its normal intermediate position the guide member 56 prevents inadvertent movement of the memory tab 50 from one band position to the other. By pressing in this pushbutton 16 the guide 56 engages the side of the projection 52 of the tab 50 and moves the band selector switch plate 28 to the right (Fig. 6, not shown) to select the FM band. Also the pushbutton 16 selects the required frequency by movement of a treadle bar and core carriage arrangement in the housing (12, Fig. 1, not shown) of the receiver. If the tab 50 is set to the FM position as shown in Fig. 5, and it is required to select the AM waveband for this pushbutton and the waveband switch slide 28 is in the AM position shown in Fig. 5. On withdrawal of this pushbutton the finger 60 moves into the recess 48 and the tab 50 pivots about 42 into the AM position, Fig. 7. When the pushbutton is pressed in, the guide 56 engages the surface of the projection 52 of the tab 50 and the waveband selector slide 28 is set to the AM position. Also when the pushbutton is withdrawn for frequency adjustment the waveband selector slide 28 may also be slid between the AM and FM positions. As the finger 60 of the associated pushbutton is in the recess 48 of the associated memory tab 50 the sliding movement of the selector slide 28 causes the memory tab 50 to be pivoted to the selected waveband position. The waveband selector switch may be selected by a lever 18 which also co-operates with the front panel of the receiver to indicate the waveband selected.
