Title: Improvements in or connected with Certain Kinds of Electrical Switches.
Inventor: READ ALBERT EDWARD
IPC: H01R13/707
Filed: 1918-04-11
Abstract: 125,215. Read, A. E., Franks, J. E., and Brooks, M., (trading as Walsall Hardware Manufacturing Co.), and Compson, W. April 11, 1918. Plug couplings combined w i t h electric switches. A combined electric switch and plug- and-socket coupling contained within a casing is provided with throwing- off mechanism, which prevents the switch contact arm from remaining in its ' on' position except when the plug has been pushed home in the socket, so that the long or earthing pin of the plug engages with the throwing-off mechanism to move it clear of the path of the contact arm. The throwing-off mechanism comprises a tension spring 23, a lever 9, 14 with cranked end 10 and insulating-block 11, a link 15, and a lever 16. The spring tends to hold the block 11 over the end 13 of the switch arm 13<x>. When the plug has been inserted, the end 9 of the lever 9, 14 is raised and the block 11 is moved to a position clear of the path of the switch arm so that the switch can be closed by turning the shaft 3<x>. If, however, the plug be withdrawn before the switch has been opened, the long pin 20 of the plug moves clear of the throwing-off mechanism and the spring 23 then brings down the block 11 to engage with the arm 13<x> and open the switch.

Title: Improvements in or relating to the production of penicillin
Inventor: HOCKENHULL DONALD JOHN DARLING
Filed: 1952-03-10
Abstract: Penicillin is produced by permeating a penicillin producing mould under deep culture conditions in a cornsteep liquor medium containing a thiosulphate and a penicillin precursor (defined) in an amount insufficient to cause substantial inhibition of the fermentation. The medium may contain 0.01 to 0.02 per cent sulphur as thiosulphate, and 0.1 to 0.2 per cent precursor.  In the case of precursors which are rapidly consumed, further additions of precursor may be made as the fermentation proceeds. Preferred precursors are phenylacetic acid, phenylacetamide, phenylacetylethanolamine and beta-phenylethylamine.  Preferred thiosulphates are sodium thiosulphate, potassium thiosulphate, ammonium thiosulphate and magnesium thiosulphate.  A suitable aqueous medium consists of 3.5 per cent lactose, 3.5 per cent corn steep solids, 0.2 per cent phenylacetylethanolamine, 0.4 per cent potassium dihydrogen phosphate, 0.08 per cent sodium thiosulphate and 1 per cent chalk. Specifications 586,930, [Group VI], 613,492 and U.S.A. Specification 2,437,918 are referred to.

Patent GB-496935-A (GB)
Title: An improved method of preserving in closed containers foodstuffs or other organic substances
IPC: A23L3/3418
Filed: 1937-03-04
Abstract: Foodstuffs and other organic materials which are liable to damage in the presence of oxygen during storage in closed containers are preserved by binding the oxygen of the air within the containers by means of oxidizable substances which are rapidly reacting at ordinary temperature but are protected from the air by provision of an air-insulating coating or admixture with agents acting to retard or prevent oxidation, the action of which is neutralized or destroyed by their being brought into contact with moisture or watery liquid before setting in of the reaction. The protecting agent with which the oxidizable substance is mixed may be a uniformly subdivided water-absorbing substance which in the dry state retards or prevents the reaction but on addition of water from a moist support or from moist goods to be preserved initiates the oxidation, e.g. sawdust, wood flour, paper pulp, or moss or peat litter. Where an air-insulating coating is employed it may consist of a substance which is dissolved or destroyed by moisture, e.g. gelatine, sugar or starch. Oxygen-absorbing preparations used include zinc dust mixed with deciduous wood sawdust, paper pulp, moss, peat litter, etc.; powdered cast iron mixed with powdered quartz and moss or peat litter; manganese dust mixed with deciduous wood flour; ferrous sulphate mixed with lime and moss or peat litter. Activated carbon may be included. Preservatives such as citric acid may also be used to prevent action of anaerobic bacteria.

Title: Induction energy meters
IPC: G01R11/36
Filed: 1967-02-10
Abstract: 1,104,060. Electricity meters. SIEMENS A. G. Feb.10, 1967 [Feb. 10, 1966], No. 6600/67. Heading G1Q. A three-phase induction-type energy meter has a 120‹-120‹-120‹ arrangement of the three main driving systems I, II, III about a common rotor disc, and diametrically opposite each is an auxiliary driving system. Fig. 1 shows the connections of the voltage coils of the driving systems: each of the auxiliary systems generates a flux derived from the voltage magnetic circuit of the diametrically opposite main system. Also (not shown) each of the auxiliary systems generates a flux derived from the current magnetic circuits of the two adjacent main systems. Fig. 13 shows one of the auxiliary systems, consisting of an electromagnet acting on the rotor disc 6 and energized by two coils 7, 8 one of which is the voltage-sensitive coil connected as shown in Fig. 1 and the other the current-sensitive coil not shown in Fig. 1. These coils are connected in series with the appropriate windings of the main drive systems. Figs. 2 to 12 (not shown) are vector and torque diagrams by the aid of which it is shown that the torques produced by the auxiliary systems compensate for the error torques which arise by interaction of fluxes produced by adjacent main driving systems. It is shown that currentcurrent, voltage-voltage, and voltage-current flux interactions are all compensated for, and that the compensation is equally effective for 'normal' or 'interchanged' phase sequence, and for 'equilateral' or 'unilateral' loading of the phases.

Title: A sewing machine having a bobbin-winding device with automatic stop motion
IPC: D05B59/00
Filed: 1946-03-04
Abstract: 613,453. Winding thread. BLAKE, W. H. (Mefina Soc. Anon.). March 4, 1946, No. 6616. [Class 120(ii)] [Also in Group VII] A sewing machine provided with a motor, a driving shaft and a bobbin winding device with an automatic stop motion is characterised in that the machine is provided with a connecting member mounted on a movable support capable of being brought manually into at least two different positions, in one of which the member connects the motor shaft mechanically with the driving shaft of the machine, whilst in the other position the said connection is interrupted, the member connecting the motor shaft to the device for winding a bobbin, a stop member being so arranged as to come into contact with the thread out the bobbin, when a desired diameter is reached, so as to repel the bobbin and the connecting member, and thus interrupt the drive between the motor shaft and the bobbin winding device. A toggle 25, pivoted at 29, carries two levers 23, 27 pivoted at 24, 28 and spring-urged at 38. The levers 23, 27 carry rollers 20, 21 freely rotating on axles 22, 26, which, may be moved, selectively, so that the driving shaft 11 of a motor shall drive the sewing machine main shaft 12 through pulleys 16, 19 for normal working, or through pulleys 15, 18 for reduced speed working. A spring-pressed recessed lever 31, pivoted at 32, operates to hold the toggle 25 in the selected position. In the middle position of the toggle, the roller 20 is driven by the pulley 15 without driving the shaft 12, and a bobbin 43, driven by the roller 20 through teeth 41 on a hub 40. is filled with thread until a roller 44 bears on the wound package to move the roller 20 away from the pulley 15. In a modification, one pulley only, such as pulley 20, is used, which may be moved longitudinally of the shaft 11 to engage selectively the grooves 15 or 16 in the motor shaft to drive the sewing machine shaft at normal or slow speed or the bobbin supporting shaft for winding on. The bobbin 43 is maintained on the spindle by the engagement of one of its flanges 42 with the face of the roller 44, which is furnished with a conical portion 46 to facilitate the positioning of the bobbin.
