Filed: 1970-09-18
Abstract: 1,261,299. Protein films; extrusion. GENERAL MILLS Inc. 18 Sept., 1970 [18 Sept., 1969 (3)], No. 44679/70. Headings B5A and B5B. [Also in Division C3] Shaped articles, e.g. flat and tubular films, are made by extruding into a gaseous medium a plastic mass consisting of an aqueous composition containing a proteinaceous substance having a protein content of at least 65% by wt., at least 50% of which is a particulate, non-heatcoagulable simple protein. Specified proteins are keratin, microcrystalline collagen, soy bean protein, alfalfa leaf protein, wheat glutein (which may contain fats and/or starch) and corn zein. Up to 95% of the liquid in the mass may be ethanol. The mass may also contain: bases, e.g. NH 4 OH or NaOH; reducing agents, e.g. Na 2 SO 3 , (NH 4 ) 2 SO 3 , NaNO 3 , NaHSO 3 , 1-cysteine hydrochloride, cysteamine, mercaptoethanol or ascorbic acid; plasticizers, e.g. glycerol, diglycerol, propylene glycol, 1,2,6- hexanetriol or triethanolamine; other agents, e.g. acetic acid, a phosphoprotein. The mass, at elevated temperature, may be extruded as a tube into ambient air, and the tube stretched by inflation, e.g. by 1-10x. The inflating agent may contain a flavour, e.g. hickory smoke. Alternatively, the tube may be flavoured or plasticized (e.g. using an aqueous or aqueous alcoholic solution of glycerol) after extrusion. Such tubes make useful sausage casings.

Patent GB-1542912-A (GB)
Title: Method of casting
IPC: B22D1/00
Filed: 1976-11-04
Abstract: A method of making a more economical and reliable treating agent for use in late metal treatment when pouring metal castings. The treating agent is defined as an essentially homogeneous solid cast block preferably containing alloying ingredients to nodulize or inoculant ferrous metal. Each block is designed to present a generally uniform reaction surface to molten metal to be treated. This is obtained by casting the block to a shape which snugly fits a prepared basin in the mold gating system over which the molten metal to be treated must flow, or to cast the block in an annular configuration through which the molten metal must flow. The latter block has contoured inner surfaces which maintain a generally constant reactive surface as the block is consumed. These blocks are preferably prepared by simultaneously casting a large number in closely nested relation. Each mold for said blocks receives molten material, out of which the agent is formed, from a common sprue; runners interconnect the mold cavities and sprue, for example, in a simulated "Christmas tree" arrangement. The gating system and mold cavity pattern, for casting the treating agent to a special shape are all comprised of a material that will vaporize upon contact by the molten treating agent, such as polystyrene. The unitary tree structure of foam patterns and gating system is placed in a flask and surrounded by unbonded heat absorbing particles, such as sand or steel shot. Rapid solidification is assured by the selection of heat absorbing particles and by the use of the vaporizable patterns to avoid noticeable segregation in the alloy blocks. The blocks formed for the treating agent are characterized by increased homogeneity, absence of undesirable segregation, absence of internal oxidation, and absence of organic or refractory impurities; the blocks are less costly to make both as to capital requirements and operating expenses.

Filed: 1973-10-08
Abstract: 1438570 Automatic control TRW Inc 8 Oct 1973 46836/73 Heading G3N [Also in Division G1] The invention relates to an electric dimension gauging system for articles periodically entering a measuring area, and provides a switching circuit for suppressing false signals when the article is not in position. The invention is described with reference to a surface grinder in which the cut is automatically increased after each pass. A sensor of the proximity-type is located at a known height above the table towards the end of its travel, and a "positionindicator" switch is actuated at the end of the travel, Fig. 1, (not shown). The gauge signal may be arranged to stop the machine when the "finished" dimension is reached. A control circuit is shown Fig. 2, the signal from sensor 30 is compared with a required value reference 36 by comparator 34. When the workpiece is in the measuring position switch 46 energizes one input of AND gate 40 so that if a stop-grind signal comes from the comparator (at that time) flip-flop 50 de-energizes the power relay and "RUN" lamp 62 and also lights the "RESET" lamp 58. The control circuit is reset by switch 52. Modifications. The apparatus may be used also for gauging articles conveyed in succession past a measuring station.

Abstract: 472,821. Game - scoring appliances. DABBS, F. T. March 26, 1936, No. 9075. [Class 132 (ii)] [Also in Group XIX] An adding or subtracting device particularly for use in scoring at the game of darts comprises two sets of indicating drums, one set for the player's score and the other for totals, the two sets being operatively connected by gearing and the drums of the totals indicator having transfer arrangements of the travelling pawl-and-escapement type between the units and tens and the tens and hundreds denominations respectively. In the form shown in Figs. 1 and 2, a casing 1 with windows 2, to expose the numerals on the indicating drums, supports two independently rotatable shafts 3, 4. To the shaft 4 is fixed a units indicating drum 7 and on the shaft 3 is keyed a tens drum 8. Adjacent the tens drum is a hundreds drum 9 loose on the shaft 3. Arranged above the shafts 3, 4 is a shaft 10 having rotatably mounted thereon numeral wheels 13, 14. The wheel 14 is marked with the numerals 0-9 representing units and carries a set of pins 17 that co-operate with a notched setting wheel 19 actuated by an external knob 12. The setting of the wheel 19 is imparted to the units drum 7 by toothed gearing 15, 16 and a one-way ratchet connection 18, 18a. The wheel 13 is marked with the numerals 0-19 and is operatively connected to the tens wheel 8 bv means similar to that between the wheels 7 and 14 and is actuated by an external knob 11. A transfer mechanism between the wheels 7, 8 is constituted by an arm 24, Figs. 1 and 5, pivoted on the wheel 7 and carrying a spring-controlled pawl 22 adapted to be moved into operative relation with pins 21 on the wheel 8 when a projection on the arm 24 moves into contact with a cam plate 26 secured to a sleeve on the shaft 10. The transfer mechanism provided between the tens wheel 8 and hundreds wheel 9, as shown in Figs. 1, 3 and 4, comprises a spring coupling element 28 on the wheel with projections 30 adapted to engage notches in a disc 29 secured to the wheel 9. The wheel 9 is held stationary by a spring-controlled arm 31 mounted on the shaft 10 engaging one of a set of pins 33 on the wheel 9. At transfer a pin 34 on the wheel 8 engages a projection on the arm 31 so as to raise the arm and free the wheel 9 for a step movement by the coupling member 28. In a modified construction shown in Figs. 10 and 12, the units and tens wheels 7, 8 are operated by gears 42, 44 and 48, 50 from shafts 41 and 51. The shaft 51, Fig. 12, carries a handle 11 and an indicating disc 47 for displaying the digit set. The indicating discs are held in position by detents 56. To reset the discs an arm 55, Fig. 10, is operated to displace the slide 53 which throws out the detents to permit the shafts 41, 51 to return to normal position under the action of weights 62 attached to cords 60 and pulleys 59 on the shafts. Zeroizing the numeral drums is effected directly by the rotation of the shafts 3 and 4. Specification 19957/09, [Class 132 (ii)], is referred to.
