Filed: 1928-04-03
Abstract: 314,145. Lifchuz, (nÚe de Salas), P., and Lifchuz, A. April 3, 1928. Cigarettes and cigars.-Self-lighting tips are made from cellulose esters in which potassium chlorate is suspended. Two coatings are given, the potassium chlorate in the first coating being much finer than that in the second. Aceto- or nitro-cellulose is dissolved in low boiling solvents such as acetone. The mixture may be stabilized and gelatinized by the addition of derivatives of aniline, urea, urethaae, or the esters of polyhydric alcohols such as triacetine and nitroglycerine. Fillers such as kieselguhr and friction sensitizers such as pumice-stone and powdered glass are used in the outer tip.

Title: Improved Process for Preserving Non-alcoholic Beer and other Fermentable Liquids.
Inventor: FRANKS-NEE-GALLAGHER HELEN CEC
IPC: C12C5/02
Filed: 1919-04-25
Abstract: 136,448. Franks (nÚe Gallagher), H. C. M. April 25, 1919. Aerating processes.-In a process for sterilizing non-alcoholic beers and other fermentable liquids by repeated treatment with carbon dioxide under pressure the liquid is maintained at a temperature of about 35‹ F. while the operation is being performed. The liquid is fed into tanks cooled by circulation of brine, and is agitated by stirrers while carbon dioxide is forced in up to a pressure of about 60 lbs. per square inch. After remaining a few minutes the carbon dioxide is exhausted till the pressure is about that of twenty-six inches of mercury, and the operation is repeated, the liquid being finally stored while charged with the gas under pressure. Before admitting the liquid the apparatus is treated with carbon dioxide and alternations of pressure to sterilize it and remove air and oxygen. Wort may be prepared and hopped in the usual way and subjected to the process before fermentation or 'at any desired stage at the fermentation, which is thereby stopped.

Abstract: 1,246,547. Fasteners: HARTWELL CORP. 26 Feb., 1969 [13 Aug.; .1968]; ,No. 10324/69. Heading E2B. A flush fastener includes a mounting plate 1, a bolt and handle lever 6 and a trigger lever 12 for holding the bolt and handle lever in a fastening position, the bolt and handle lever and the trigger lever having portions which engage in a fastening condition, the bolt and handle lever being biassed by a first spring 22 to the releasing position and the trigger lever being biassed by a second spring 26 to the holding position, the force applied by said first spring being higher than the force applied by said second spring by a ratio in the range between 8:1 and 30:1, thereby creating an unstable relationship between the levers when a dead centre position is passed in the releasing direction, whereby said trigger lever snaps towards its releasing position, a coefficient of friction of between 0.01. and 0.4 existing between said mutually engaging portions. In the, construction shown, the trigger lever 12 engages the bolt lever 6 to hold it in the, bolting position and the portion of the bolt lever engaged by the trigger lever is a roller 20 mounted on a pivot pin 19; in a modification the trigger lever includes a roller and this engages a shaped surface of the bolt lever. In a further modification both the trigger lever and the bolt lever include rollers which engage each other. A further construction is described in which the end portion of both the trigger lever and the bolt lever have a covering of p.t.f.e. material to reduce the friction. Fig. 13 shows an alternative fastener in which the bolt lever has a hook' end portion and in which the trigger lever engages' a roller disposed between the ends of the bolt lever. A further form of fastener is shown in Fig. 12; in this fastener the bolt lever is coupled to a bolt by a link 37 and the trigger lever engages a roller connected to a frame which supports the bolt lever the trigger lever and the bolt. Fig. 14 shows part of a further form of fastener which is a modification of the fastener'disclosed in U.S. Specification number 2833582; the bolt lever 46 is coupled by a shaft 47 to a bolt (not shown) the lever being movable axially of the shaft 47 to enable the trigger lever to engage a roller 41 which forms part of the fixed frame; when the trigger lever, which is pivoted to the bolt lever, releases the bolt lever it is first moved axially by a spring 48 and can then be manually rotated to rotate the bolt.

Abstract: 417,934. Tunnel kilns. WOODALL-DUCKHAM (1920), Ltd., and CLARK, A. N., 136, Victoria Street, London. April 7, 1933, No. 10462. [Class 51 (ii).] In a tunnel kiln having firing and preheating zones and a heating system adapted for direct heating alone, muffle heating alone, or for both kinds of heating simultaneously, means are provided by which the delivery of heating gases directly into the tunnel may begin at any selected point of the firing zone and be effected over any desired length thereof. As shown, the combustion flues E in the walls of the firing zone are supplied with gas and preheated air from roof passages F, G, and deliver into a longitudinal flue I which communicates with the interior of the tunnel through damper-controlled ports J. At the junction C of the firing and preheating zones, the flue I delivers to flues K which discharge into the stack flue L at the charging end of the tunnel and communicate with the interior thereof through damper-controlled ports M. Offtake openings P, connected to the uppermost flue K, are provided adjacent the inlet end of the tunnel. By appropriate setting of the dampers controlling the ports J, M, the tunnel may be either directly heated or muffle heated throughout, or the direct heating may begin at any desired point with muffle heating of the part or the firing zone in front of this point. When any substantial number of the ports J are open, some of the ports M must also be left open to serve as additional off takes and prevent escape of gases from the end of the kiln. Dampercontrolled openings N are provided in the roof of the preheating zone for the supply of preheated air from the roof flue O ; preheated air may be similarly supplied at any part of the firing zone. Specification 340,271 is referred to.

Abstract: 1467518 Fuel injection pumps ROTO DIESEL 8 March 1974 [14 March 1973] 10462/74 Addition to 1414674 Heading F1A In a rotary distributer fuel injection pump according to the main patent (1414674) wherein the maximum permitted outward excursions of the radial pumping plungers 15 are determined by the abutment of roller shoes 33 with the ends of a leaf-spring stop 36, the contacting surfaces of the shoes and the ends of the leaf-spring are complementarily inclined. Thus axial displacement of the carrier 19, 20, 21 results in a proportional change in the maximum outward strokes of the plungers. Displacement of the carrier is effected by fuel pressure actuated rams 37 having reduced diameter ends extending through respective holes in a stop plate 38 into contact with the carrier. After a predetermined displacement the large diameter part of the rams 37 abuts and then takes with it the stop plate 38 until the latter contacts a maximum fuel stop member 39. Accordingly stop member 39 determines the maximum amount of fuel which can be supplied during normal operation. The actual amount of fuel supplied is controlled by means (not shown). The axial position of the member 39 is manually adjustable by a tapered member 40. In a second embodiment, Fig. 3 (not shown), an additional pair of plungers is provided, each plunger having a tongued and grooved outer surface co-operating with a complementarily shaped surface on the leaf stop as described in the main patent. The fuel delivered by the additional plungers may be separate from, or combined with, the fuel delivered by the plungers 15.
