Title: Improvements in or relating to the spool carriers of braiding machines
IPC: D04C3/14
Filed: 1954-09-14
Abstract: 783,096. Braiding. JARDINE, C. B. Sept. 14, 1954 [Sept. 21, 1953], No. 26536/54. Class 74 (1). A braiding machine yarn spool 10 is prevented from rotating until a supply of yarn is required, and is then permitted to rotate only to a predetermined extent, regardless of the speed at which the machine is operating. Yarn from the spool, rotating with a tube 5, is led up through an eye 19 on a tension post 11, down under a hook 20a on a slide 20 and up through an eye 15 to the braiding point. As yarn is taken up by the movement of the bobbin carriers, slide 20 rises, against the action of a spring 13, until it engages a loop 32 of a rod 31 which, in rising, raises the free end of a lever 24, to bring a lug 25 on the lever into the path of the teeth of an escapement wheel 8 fast with the tube 5, and also lifts a stop 33, which it carries at its lower end, out. of engagement with a tooth of the escapement wheel. The wheel is then free to rotate counterclockwise, Fig. 4, under the pull of the thread until a tooth drops on to and is arrested by the lug 25. The yarn tension having thus been eased, the slide 20 descends again, the rod 31 and lever 24 fall, to locate stop 33 in the path of the wheel teeth and that tooth of the wheel 8 which had been arrested by the lug 25, passes over it (for this purpose, pushing down the lever 24 beyond its normal rest position against the action of a light leaf spring 26 or helical spring) and comes to rest against the stop 33. The lug 25 now rises behind the tooth, which is thus locked by it and the stop 33 against rotation of the wheel and either direction. Wings 21 on slide 20 operate a stop motion if the yarn breaks. The tube 5 is retained endwise on the supporting post 3 by springs 4 and the spool is constrained to rotate with the tube 5 by resilient wire members 7.

Title: Improvements in radiators for internal combustion engines
IPC: F28D1/03
Filed: 1919-10-29
Abstract: 137,033. Berkovici, L. Dec. 27, 1918, [Convention date]. No Patent granted (Sealing fee not paid). Plate apparatus.-The elements of a radiator for an internal-combustion engine are formed of two corrugated metal sheets d<1>, Figs. 2 and 6, which are spaced apart so as to form a water channel a between them by offsetting one of the edges e of each sheet which are at right-angles to the corrugations, and bringing the two sheets together, as shown in Fig. 4, so that the offset portion of one sheet is in close contact with the plain portion of the other sheet. A complete radiator is built up as shown in Fig. 7 by arranging a series of such elements with the apexes of the corrugations in contact so as to form air spaces b between the elements, the structure being united by immersion in a bath of tin. Reference has been directed bu the Comptroller to Specifications 28615/04 and 12528/06, [both in Class 29, Cooling &c.].

Title: Electro-magnetically actuated spring clutch
IPC: F16D13/02
Filed: 1975-06-24
Abstract: 1517536 Friction clutches MARQUETTE METAL PRODUCTS CO 24 June 1975 [26 June 1974] 26728/75 Heading F2C In an electromagnetically actuated helical spring clutch wherein a helical spring 54 frictionally engages driving and driven drums 28, 40 when a surrounding control sleeve 58 is free to rotate, the control sleeve 58 is connected to one end 56 of the spring 54 and has a radial projection 72 which engages a slot 70 in a non- rotatable armature 60 to stop the sleeve and expand the spring out of engagement with the driving drum 28. As shown the clutcn is engaged when an electromagnet 24 is de-energized. On energization of the electromagnet 24 the armature 60 moves left against the bias of a spring 66 to cause the slot 70 to engage the projection 72 on the control sleeve 58 and thus effect clutch disengagement. The control sleeve 58 may be removed and replaced after end-to-end reversal whereupon the slots 70 in the armature 60 engage a projection 72a on the control sleeve 58 when the electromagnet is de-energized. On energization of the electromagnet the armature 60 moves left to disengage the slots 70 from the projection 72a and thus permit clutch engagement.

IPC: F04C2/107
Filed: 1968-06-05
Abstract: 1,220,848. Rotary pumps and motors. MONO PUMPS Ltd. May 23, 1969 [June 5, 1968], No.26743/68. Heading F1F. An eccentric rotary pump or motor comprising a stator, a rotor eccentrically rotatable with respect to the stator, and a flexible shaft secured to the rotor to drive the rotor or receive drive therefrom, the flexible drive-shaft being coated with a non-permeable and non-porous layer of material. Applied to a rotary internally-meshing helical gear pump, a housing 11, Fig.1, mounts a resilient stator 10 having a helically-threaded bore 12 within which a helically-threaded rotor 13 having one start more or less than the stator eccentrically rotates. The rotor 13 is screw-threadedly attached to a drive shaft 15 having a coating of a chlorinated polyether, nitral rubber or epoxy resin. The shaft at each end includes an enlarged portion 16 covered by the coating which sealingly engages in a countersunk bore 23 in the rotor and a similar bore in the drive or driven member (not shown) to protect the shaft against the pumped material which is often corrosive liquids or powders. The proportions of the shaft 15, e.g., 60 ins. long and 0À75 ins. diameter, are such to permit the shaft to flex sufficiently to allow for the eccentricity of the rotor, the layer 21 preventing corrosion fatigue. In another embodiment, in which the rotor may be rotated in either direction, the rotor includes an enlarged diameter bore 38, Fig.3, extending substantially through the rotor and a screw-threaded portion 43 having a right-hand thread and a screwthreaded portion 45 having a left-hand thread which engages a lock-nut 46. In modifications, the screw-threaded portion 43 may be replaced by complementary tapers on the rotor and shaft and the screw-threaded portion 45 by screw-threaded bores in the end of the shaft into which a locking screw is inserted.

Title: Improvements in or relating to substances produced by penicillin-producing moulds
Inventor: DOYLE FRANK PETER
IPC: C07D499/42
Filed: 1957-08-02
Abstract: The invention relates to 6-aminopenicillanic acid having the structural formula:  <FORM:0870396/IV (b)/1> which is capable of reacting with phenylacetyl chloride to produce benzyl penicillin and which gives a negative Bratten-Marshall test and a negative Ninhydrin test, and its salts.  It is present in the fermentation liquors produced by growing a penicillin-producing mould, e.g. Penicillium chrysogenum in a nutrient medium preferably in the absence of a precursor.  It is isolated from the clarified concentrated broth by adsorption on an ion exchange resin, preferably after penicillins have been removed by solvent extraction of the liquor at an acid pH with an organic solvent for the penicillins e.g. butyl acetate.  The resin may be (a) a basic anion exchange resin e.g. cross-linked polystyrene with quaternary ammonium groups e.g. Dowex I or (b) an acid cationic exchange resin e.g. cross-linked polystyrene with sulphonic acid groups e.g. Amberlite IR,120.  Prior to adsorption the liquor may be adjusted to pH7,0 and impurities precipitated by the addition of a water-miscible solvent such as acetone.  The eluate from the resin may be purified by chromatography on a cellulose column before the 6-aminopenicillanic acid is precipitated by the addition of acid.
