Patent GB-720477-A (GB)
Title: Improvements in or relating to anti-virus agents, and the preparation thereof
IPC: A61K31/65
Filed: 1951-11-05
Abstract: An antivirus agent is obtained by maintaining a solution of oxytetracycline under mildly alkaline conditions until substantial antivirus activity (test micro-organism influenza virus) is imparted to the solution.  The solvent may be water, a water-miscible organic solvent, e.g. alcohol or a mixture thereof.  A pH of 10 to 12 and a temperature of 20 DEG  to 100 DEG  C. is preferred.  The higher the temperature, the shorter the digestion time.  Thus at 20 DEG  to 35 DEG  C. the time is 2 to 10 days; at 90 DEG  to 100 DEG  C. the time is 1/2 to 3 hours.  The lower temperature produces the most active product.  The agent may be isolated from the solution by (a) freezy-drying or (b) acidifying to pH 2 to 4 and filtering off the separated solid.  The original solution may be rendered alkaline by an organic or inorganic base, the alkali metal hydroxides being preferred.  Any strong acid may be used in step (b); preferred are phosphoric, sulphuric or hydrochloric. The antivirus agent is active against the influenza A virus; has low solubility in dilute, aqueous acid; the acid form is soluble in acetone, methanol, butanol and pyridine, but insoluble in ether, chloroform, dioxane and acetonitrile; its activity against Klebsiella pneumoniae is preferably less than 10 per cent of that of oxytetracycline.  The agent may be used therapeutically with other antibiotics (see Group VI).ALSO:A therapeutic preparation comprises a solution of an antivirus agent obtained by maintaining oxytetracycline under mildly alkaline conditions until substantial activity against the influenza A virus is obtained (see Group IV (b)].  Optional additions are penicillin, streptomycin, "Viomycin" (R.T.M.) or oxytetracyline.

Title: Improvements relating to apparatus for playing gramophone records
Inventor: METCALFE CLIFFORD
IPC: G11B3/20
Filed: 1950-10-24
Abstract: 705,376. Supporting gramophone pick-ups. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Oct. 24, 1951 [Oct. 24, 1950], No. 25822/50. Class 40 (2). The pick-up arm 54 is supported in its rest position on an arm 46 having an upstanding end 65 with side notches 66. The other end of the arm 46 has an aperture to engage around a bush 44 for the pick-up shaft 45. The arm 46 is free to move around.the bush, but a compression spring 47 forces a collar 39 of the bush down against the arm so that it is held in position, until it is positively moved. In a modification, Fig 4 (not shown), the arm 46 is held in position on the bush 44 by a rubber grommet. The rest can thus be moved into suitable positions for various sizes of records either directly or by pressing on the arm 54 and thus causing a spring clip 63 to engage in the notches 66, and then moving the arm 54 to move the arm 46. The pick-up is balanced by a tension spring 56, the tension of which is adjusted by varying the size of a wire bight 58. A rubber rib 69, Fig. 1, prevents the stylus from being damaged, if the pick-up is accidently dropped onto the motor board. The turntable 17 is driven from a resiliently mounted motor, through the motor shaft 26 and friction wheels 27, 31, the wheel 31 engaging the rim of the turntable. The wheels are urged against the shaft 26 and the turntable by a spring. By removing a screw 33, the wheels 27, 31 may be removed and replaced by a different set of wheels to drive the turntable at a different speed.
Patent GB-260371-A (GB)
Abstract: 260,371. Sumner, W. Aug. 14, 1925. Time-checking apparatus, check and token.- A receptacle which is closed at a time that is indicated automatically by the starting of a stopwatch is provided with means to destroy a seal by the unlocking action of the closure member. As described with reference to a bag or container 1, Fig. 1, the hinged cover 4 contains a rotatable frame 5 carrying a stop watch 6, Fig. 4, and is provided with a lid 7, Fig. 5, having a hook 20 for perforating a seal 24. When the lid is closed on the casing 4 and moved in the direction of the arrow a, the bayonet-joint members 8, 9 are engaged and a spring catch 10 on the casing engages a recess 11 of the lid to prevent its rearward movement. After the articles have been inserted into the bag, the casing is folded down and slots 13 in the members 4, 5 are engaged by a hooked catch on the rim 2. The frame 5 is then rotated in the direction of the arrow b by means of a projecting piece 14 to cause the locking engagement of the member 13 and catch. This rotary movement also causes the engagement of the abutment 16 with an element 15 to stop the watch, the engagement of a spring catch 18 on the casing with a recess 17 of the frame 5, and the release of the lid by the disengagement of the catch members 10, 11 by the movement of a projection 19 of the casing. When the lid is rotated rearwardly to release the bayonet-joint elements 8, 9 to open the receptacle, a hook 20 on the lid is forced upwardly by a cam 22 on the frame member, to perforate a seal positioned beneath an aperture 23. In the arrangement shown in Fig. 11 for locking the drawers of a filing cabinet, the device is contained in a casing 28 positioned immediately behind a drawer and provided with a locking bolt 26 operatively connected with the stop-watch 6 and a member 20<a> for perforating a seal 23<a>. A projection 30 on the bolt engages an arm 31 of a rotatable frame 5a housing the stop-watch 6, and when the bolt is moved to lock the drawer the watch is stopped by the engagement of the stop element with a fixed abutment. The bolt is moved by a knob 27 on a rod 32 slotted at 33 to receive a pin 34 on the bolt. A spring-controlled pawl 35 is pivotally mounted on a frame on the rod, and when the bolt is shot the pawl trails over an element 37 on a shaft 29. The withdrawal of the bolt causes the pawl to depress the member 37 and rotate the shaft 29, the device 20<a> then puncturing the seal. The hinged lid 38 is engaged when closed by a catch 41 connected by a wire with the member 37. By this arrangement the lid is not free to be opened until the bolt 26 has been retracted, this action causing the rotation of the shaft 29 to puncture the seal, and at the same time causing the catch 41 to be released through the pull on the wire 42.

Title: Improvements in or relating to the removal of impurities from water
IPC: C02F1/26
Filed: 1954-09-10
Abstract: 768,577. Purifying water. STAMICARBON N.V. Sept. 10, 1954 [Sept. 14, 1953], No. 26274/54. Addition to 708,355. Class 46. [Also in Group II] The method of the parent Specification is used to disperse oil in water to remove soluble impurities therefrom; the rotation chamber used in that method is located with at least its discharge aperture immersed in the body of water to be purified. The rotation chamber may be of one of the forms described in the parent Specification (though not restricted to these), the form comprising a cylindrical portion with one or more tangentially-directed feed passages for the vortex-forming water and an adjoining conical portion having a discharge aperture in its apex being preferred. The preferred diameter of the chamber is of the order of a few centimetres, a desired capacity of apparatus being attained by employing a plurality of chambers in parallel, optionally combined in a structural unit as described in the parent Specification. The chamber is preferably totally immersed in the water to be purified. The shape and dimensions of the rotation chamber and the feed pressure under which the vortex is formed are preferably such that the depression in the vortex core is large enough to be entirely responsible for the feed of oil to the core. The oil is preferably used in a quantity up to 1 per cent by weight of the water to be purified, and may be a fatty oil or a mineral oil. A portion of water to be purified may be withdrawn from a reservoir 1, Fig. 1, containing it, and pumped by a pump 2 through a pipe 9 to a rotation chamber 3, Fig. 2, so as to form a vortex therein. An axial feed conduit 4 supplies paraffin oil from a reservoir 5, and a liquid (which eventually leads to the formation in the water of a finely-distributed material which breaks down the oil dispersion) such as ferric chloride from a reservoir 6, to the vortex produced in the rotation chamber. The ferric hydroxide formed, together with the oil, settles in about two hours without an appreciable amount of oil appearing on the surface. In Fig. 3 a pump 32 draws water from a pipe 30 and supplies it to a rotation chamber 31 located in the pipe, oil and an additional reagent being drawn from containers 34 and 35 respectively. At a distance along the pipe governed by the time required for the formation of the deposit and completion of the purifying process, a filter 36 is provided. In all cases the vortex may be formed from water from another source. Specification 714,904 also is referred to.
