Title: Improvements in or relating to a releasable holding device for flexible material payed out from a winding mechanism
IPC: B67D7/40
Filed: 1951-07-18
Abstract: 721,214. Rope stoppers. PILLIN, Ltd., J. B., EARLY, K. C., and MORLEY, N. F. July 18, 1952 [July 18, 1951], No. 17018/51. Class 78 (2). A holding device, Fig. 6, for a predetermined length of flexible material paid out from a winding device comprises an enlargement 104 fixed on the flexible material at the predetermined distance, a fixed support 2 past which the flexible material moves as it is paid out, a resiliently yielding stop member 4 mounted on said support so as to be engageable by said enlargement, a detent mechanism 11 mounted on said support and having a part movable into and out of the path of movement of said enlargement, and a transmission between said resiliently yielding stop member and the detent mechanism whereby paying out of the flexible material causes the enlargement to move into engagement with the , resiliently yielding stop member which in turn forces the detent mechanism into the return path of movement of the enlargement so as to block its passage there-past, and whereby the next movement of the resiliently yielding stop member caused by engagement of the enlargement returning in the same direction retracts the detent member from the path of movement of the enlargement whereby the flexible material may be unwound. As shown, Fig. 1, hose 102 having nozzle 108 is unwound from spring drum 101 and retained in run-out position by the engagement of collar 104 with clamp device 106. As the hose is pulled through said clamp device, the collar 104 engages, Fig. 6, spring-pressed pawl carrier 4 and presses it backwards so that pawl 11 (which is carried by carrier 4) engages ratchet wheel 12 and steps it through 45 degrees; the ratchet 12 carries pins 15, Fig. 4, which consequentially rotate to engage and advance locking pin 24; and locking pin 24 consequentially engages and locks finger 31 secured to arm 40 carrying roller 33 so that when the hose is released it jams against roller 33 which is now fixed, a second roller 33 being similarly fixed by operation of second locking pin 24 also operated by a second set of pins 15. To release, the hose is pulled out a little so as to engage carrier 4 again and thus to rotate ratchet wheel 12 through a further 45 degrees which rotation swings pins 15 away from the respective locking pins 24 and frees the rollers 33 which accordingly separate and let pass the collar 104 so that the hose coils on drum 101.

Title: Equipment for effecting synchronous gear changing in variable speed gear boxes for motor vehicles
Inventor: BILDAT BENNO
IPC: B60K20/00
Filed: 1968-04-11
Abstract: 1,213,233. Change-speed control. K. H. SCHMIDT. 11 April, 1968 [14 April, 1967], No. 17478/68. Addition to 1,111,246. Heading F2D. The gear changing mechanism described in the parent Specification is modified to prevent unintentional shift by maintaining the selected ratio relay 24, 25 or 26 energized for the period of the gear shift operation, determined by the time for which the delayed release relay 15 is energized. As shown in Fig. 1 the selector switch contact arm 31 is held in its selected position by a rotary member 29 formed with locking slots 30 and operated by a solenoid 33 energized by the relay 15. The member 29 is released, when the gear G is put into neutral, by a switch S which de-energizes the relay 15. In the form according to Fig. 2 the selector switch arm 43 is rendered ineffective by a change-over switch 41 which, when relay 15 is energized, cuts off connection with switch 43 and establishes connection with additional contacts 34, 35, 36 in the ratio relay circuits 24a, 25a, 26a. This arrangement enables the switch 43, during a gear change operation to be preset for a further gear shift to be initiated upon completion of the current gear change.

Title: Improvements in liquid flow control valves
Inventor: BOWERS ERIC HIDER
IPC: F15B13/02
Filed: 1958-06-02
Abstract: 886,022. Valves. DOWTY HYDRAULIC UNITS Ltd. May 22, 1959 [June 2, 1958], No. 17557/58. Class 135. A liquid flow-dividing valve has a valve member 11 slidable in a bore 2 and formed with restricted openings 15, 16 through which the divided flows pass from an inlet 4 to ports 5, 6 leading to outlets 5A, 6A. The pressures downstream of the openings 15, 16 act on the valve member so that the latter moves to throttle one of the ports 5, 6 should the flow through the corresponding outlet tend to increase relative to that through the other outlet. The valve member may be moved to isolate the outlet 6A and place the outlet 5A in unrestricted communication with the inlet by operation of a servopiston 17 to connect a vent 23 through ports 21 with the chamber to the right of the valve member so that the latter moves to the right until its left-hand end clears the portion of the bore 2 between the port 5 and an inlet chamber 3. The valve member is returned mechanically by the hollow piston rod 18 towards its central position when it is required to resume its flow dividing function. The mechanical operation may be dispensed with if a caged spring is provided to return the valve member towards its central position on closure of the vent valve constituted by the ports 21. A vent valve arrangement may also be provided at the left-hand end of the valve so that liquid may be delivered to either outlet individually. In a further modification, the valve member is operated mechanically in both directions through a lost-motion connection with the servopiston rod.

Title: Method of fermenting yeast fermentable substrate
IPC: C12C11/00
Filed: 1965-04-27
Abstract: In producing a potable beverage, such as beer, by the fermentation of a yeast-fermentable substrate pitched with yeast at a concentration of at least 3 grams of yeast per litre of substrate, the substrate is agitated to keep the yeast in suspension, in order to inhibit the production of off flavours the temperature of the substrate is maintained at a relatively low fermentation temperature until the yeast propatation of the fermentation process is substantially completed, and then the temperature of the substrate is raised to a relatively high fermentation temperature to accelerate the fermentation process. The relatively low and high fermentation temperatures should be (1) at or below 65 DEG F. and above 70 DEG F., respectively, for top fermenting yeasts and (2) below 55 DEG F. and above 60 DEG F., respectively, for bottom fermenting yeasts.  The low temperature should, practically, be above 45 DEG F. Pitching rates between 15 and 30 grams of yeast per litre of wort are preferably employed.  In the procedure of the examples, using a fermenter 27 inches deep and having a jacket about 9 inches deep for temperature-controlled water or brine, the temperature of fermenting ale wort was held at 65 DEG F. for 8 or 16 hours and then raised to 75 DEG F. or 80 DEG F. until a desired gravity was reached.  The fermented wort was held at 75 DEG F. for 10 hours and then cooled to 40 DEG F.

Title: Improvements in or relating to forming or making particles or pieces of solid materials into shapes and the products resulting therefrom
IPC: C04B12/04
Filed: 1945-07-12
Abstract: Finely divided silica of a uniformly amorphous character containing predominantly minute spheres less than 0.3 micron in size originally produced in that condition without any mechanical grinding is used as the bonding-agent in the manufacture of bricks, ramming-mixtures, or spraying-compositions, particularly of refractory materials.  The silica may be prepared by extracting the vapour from siliceous material such as quartz and rapidly chilling it below solidification point; by partially reducing silica by heating with a reducing-agent and condensing the evolved gas under oxidising conditions; by heating silicon under such conditions that complete oxidation is prevented and condensing the evolved gas under oxidising conditions; or by condensing in contact with air or a liquid cooling-agent the gas evolved in the production of ferro-silicon by reducing quartz with carbon in the presence of iron.  The silica acts as a plasticizer for the grains and as a lubricant during pressing, and serves also to increase the bulk density and crushing-strength of the product.  The silica may be used in an amount up to 15 per cent. of the total weight, the remainder being constituted by refractory grains of, for instance, ground quartzite or magnesia, and may be introduced in dry condition or as a suspension in a liquid such as water.  A small amount of a material such as sodium silicate may be added to facilitate setting.  On heating, the silica is unchanged chemically when used with such refractories as quartzite, but undergoes crystallization; when used with magnesia, heating results in some formation of forsterite which acts as the final bond.

Title: Production of conjugated diolefines
Inventor: BETHELL JAMES ROBERT
IPC: C07C5/48
Filed: 1961-05-19
Abstract: Conjugated diolefins are obtained by reacting a mono-olefin, containing a chain of at least four carbon atoms, in the vapour phase with oxygen in the presence of a catalyst comprising phosphoric acid deposited on a tin oxide.  The mono-olefin, e.g. a butene (to form butadiene) or 2-methyl-butene (to form isoprene), may form 1-25% and oxygen 1-21% by volume of the reaction mixture, the remainder being a diluent, e.g. nitrogen and/or steam, oxygen being added as air if desired.  Reaction is effected at 200 DEG -500 DEG C. at atmospheric pressure or below or above for 1-30 seconds.  The catalyst may be formed by adding phosphoric acid to the catalyst as such or as ammonium phosphate to give about 6% of phosphorus calculated as phosphoric acid; some tin phosphate may be formed.  Any tin oxide may be used, e.g. stannous oxide, stannic oxide, meta-stannic acid or mixtures thereof formed by hydration of a salt or the action of nitric acid on tin metal.  The catalyst may contain a support, e.g. silica, and is preferably heated to 600 DEG -1000 DEG C. before use and heated to this temperature in air for reactivation.  Graphite may be used in the preparation of the catalyst.

Filed: 1970-04-16
Abstract: 1304938 Determination of amino acids LKBPRODUKTER AB 16 April 1970 [23 April 1969] 18301/70 Heading B1X Amino-acids in a protein molecule or protein hydrolysate adsorbed on a solid support are determined by reacting the protein molecule with a gaseous coupling agent to form a protein derivative, splitting the protein derivative by means of a splitting agent at the first peptide bond to form an amino acid derivative and a protein residue, removing the amino acid derivative in the gas phase and identifying it. In the apparatus shown, granulated solid support material 10, for example etched glass is fluidized in reactor 1 by inert carrier gas from 27, and protein solution is introduced via 13. Volatile coupling agent, for example an isothiocyanate or cyanate, volatile buffer, a blocking agent to couple with reactive functional groups in the protein molecule and a splitting agent for example an acid are introduced into the carier gas stream by means of doser 2 (Fig. 2, not shown). The blocking agent may be a silicon compound which serves also to increase the volatility of the amino acid derivative formed; the blocking groups are removed from the protein residue by hydrolysis before the next coupling step. Excess reagents &c. leaving reactor 1 are passed to low vacuum pump 4. The reactor is then connected via absorber 3 to high vacuum pump 5 to transfer the amino acid derivative from the reactor to the absorber. The temperature of absorber 3 is raised and the derivative swept into an analyser 6 by the carrier gas stream. The analyser may be a gas chromatography column. The aparatus is preferably automatically operated.
