Abstract: 625,716. Seats and mountings therefor. MONROE AUTO EQUIPMENT CO. May 28, 1947, No. 14214. Convention date, Dec. 11, 1944. [Classes 52 (i) and 52 (ii)] [Also in Group XXXII] A vehicle seat is mounted on the frame 29 by means of a resilient buffer (see Group XXXII) comprising a coil spring 13 and a hydraulic shock absorber 14 the buffer being situated at the rear of the seat, means also being provided for slidably mounting the seat proper in its support and for vertically adjusting the seat support. Fixed to the vehicle frame 29 are a pair of plates 27 connected by cross shafts 34, 36 to which are pivoted arms 32, 33 the other ends of the arms being pivoted to the movable support for the seat. The seat support also comprises two parallel plates 30 the front edges of which are inclined and are parallel to similarly inclined rear edges of the plates 27. The seat support is rigidly connected at the rear to a U-shaped member 42 arranged on the resilient buffer, the member 42, and therefore the seat, being vertically adjustable by means of the screwed tubular member 39 and nut 41 carried by the member 42. Secured to the base 15 of the seat 10 are channelled guides 18 whereby the seat is slidably adjustable on rollers 19 carried by the seat support. A spring-pressed plunger 21 carried by the seat is adapted to enter a selected aperture 22 on the seat support to lock the seat in horizontally adjusted position, a lever 25 being provided to retract the plunger 21 when it is desired to readjust the seat. Stops 20 are provided for limiting the horizontal adjustability of the seat. In a modification the vertical adjustment of the seat may be obtained by means of a screwed rod secured to the plates 30 and passing through a nut rotatably mounted on an abutment at the top of the resilient buffer. In a further modification the U-shaped member 42 may be provided with rack-like teeth engageable by dogs carried on an axially-movable rod.

Title: Production of pyrogen-free penicillinase
IPC: C12N9/86
Filed: 1958-05-05
Abstract: A pyrogen-free penicillinase suitable for use in injection therapy for combatting allergic hypersensitivity to penicillin is produced by inoculating a sterile nutrient broth with a viable inoculum of a penicillinase-producing microorganism especially Bacillus cereus NRRL-B569, propagating the microorganism within said broth under aerobic sterile conditions while stimulating the production of penicillinase by said organism through the controlled addition of sterile penicillin salts thereto at fixed intervals during the fermentation cycle, the resulting penicillinase being liberated from inert impurities following completion of the fermentation cycle by removing solids from the broth, adding a solute such as acetone to the clarified broth to precipitate the penicillinase which is then dissolved in pyrogen-free water and then fractionally precipitated with ammonium sulphate and separated from the ammonium sulphate by dialysis against a sodium chloride-pyrogen-free water solution to provide a solution of isotonic composition and recovering the solid penicillinase by vacuum drying said solution in a pyrogen-free state. The preferred nutrient medium contains corn steep liquor, yeast extract, lard oil and a phopshate buffer solution containing KH2PO4 and Na2HPO4 in water and having a pH of 6.95 to 7.05.ALSO:A composition in injectable dosage unit form for combatting allergic hypersensitivity to penicillins comprises essentially pyrogen-free penicillinase (see Group IV (b)) in sterile aqueous solution.  The solution may contain 100,000-5,000,000 units of penicillinase per c.c. of solution.

Abstract: 611,872. Type-bar making machines. LINOTYPE & MACHINERY, Ltd., SCOTT, R. H., and HAYWARD, A. S. May 11, 1946, No. 14315. [Class 100(iii)] Escapements.-An escapement mechanism for controlling the release of matrices from the magazine of a typographical composing machine comprises an escapement lever and means which serve the dual purpose of operating and supporting it. The escapement lever 4, Fig. 1, for releasing matrices 7 from a magazine 1, Figs. 1 and 3, engages convex surfaces on a cross-bar 15, and is pivoted to its release position by a plunger 10 actuated by a striker 11, being returned to the holding position illustrated by a plunger 12 actuated by a spring 13, which plunger acts as a support for the lever. On retracting the plunger 12 against the spring action, the lever can be removed. A plurality of escapement levers and mechanisms are located side by side to release matrices from adjacent channels in the magazine. Alternatively, the levers 4 together with the members 3 forming the escapement bar may be mounted on the machine independently of the magazine. The magazine is fitted to 'the machine frame 2, which engages a pivoted lever 26 in operative connection with a lever 22 pivoted at 23 to hold a locking bar 19 out of the path of the plunger 10. On removal of the magazine from the machine, a spring 28 presses the inner ends of the levers 22, 26 upwards to bring the bar 19 into the path of the plunger 10 and prevent release of the matrices.

Title: Process for the manufacture of terephthalic acid
Inventor: GARDNER CYRIL
IPC: C07C51/275
Filed: 1954-05-17
Abstract: Terephthalic acid is prepared by a process which comprises oxidizing para-tertiarybutylbenzoic acid with nitric acid of an initial strength between 2 per cent and 60 per cent by weight at a pressure of from 100 to 600 p.s.i. and a temperature of from 150 DEG  to 260 DEG  C.  The process may be operated batchwise or continuously and oxydation catalysts, e.g. vanadic acid or copper nitrate, may be employed.  In examples: Para-tertiarybutylbenzoic acid is heated with 18 per cent nitric acid at 230 DEG  C. and 400 p.s.i. whilst further nitric acid of 70 per cent concentration is injected during the reaction to obtain terephthalic acid containing some unchanged para-tertiarybutylbenzoic acid (1); and terephthalic acid is obtained by heating para-tertiarybutylbenzoic acid with 13.5 per cent nitric acid at 240 DEG  C. and 500 p.s.i. pressure in the presence of ammonium metavanadate and copper. Para-tertiarybutylbenzoic acid may be obtained by the oxidation of para-tertiarybutyltoluene which may be synthesized from toluene and either tertiarybutyl chloride or isobutene, e.g. by reaction in the presence of ferric chloride. Specifications 655,074, 662,139, 662,229, 698,734, and 758,676 are referred to.

Abstract: 847,606. Doors for resisting fluid pressure. LEEDS & BRADFORD BOILER CO. Ltd., and PICKARD, H. M. H. May 8, 1957 [May 9, 1956], No. 14397/56. Class 123(1) Quick-opening doors for pressure vessels of the form described in Specifications 412,700 and 667,929, wherein the door 1 is held to its seating by a series of pivoted latches mounted in a keep ring 2 and which by rotation of an operating ring 3 may be simultaneously moved into and out of the locking position, are prevented from opening fully when the latches are unlocked to reduce the risk to the operator if a pressure remains in the vessel by a trigger 4 comprising two arms 8, 9 pivotally mounted on a bolt 5 on the front of the ring 2. When the operating ring 3 begins to be rotated to the door-closing position the arm 8 is clear of the door 1 while the outer arm 9 is engaged by a lug 10 on the ring to swing the arm 8 into the position shown, in which it obstructs the door 1. When the ring is moved to the door-opening position the trigger which remains in position prevents the door from opening more than a small distance so that any pressure in the vessel is released without danger. The trigger can then be swung clear of the door by a handle 12 and the door fully opened. A cam surface 13 is provided on the back of the trigger to enable the closing door to move the trigger clear of the opening without damage to the seal.
