Title: An improved machine for severing lengths of endwise moving stock
IPC: B23D45/18
Filed: 1947-05-29
Abstract: 627,448. Sawing. BIGWOOD & SON, Ltd., J., and TINLEY, E. L. May 29, 1947, No. 14266. [Class 145(ii)] A machine for severing endwise moving stock 25 comprises a primary carriage 16 mounted on a bed 10 for movement parallel to the path of travel of the stock and having means 45 for gripping the stock, clutchcontrolled means for driving the said carriage in the same direction as the stock, a secondary carriage 40 mounted on the primary carriage for movement transverse to that of the stock and carrying a powerdriven severing tool 48 (e.g. a saw), together with mechanical means on the bed and on the secondary carriage for imparting the said transverse movement to the secondary carriage during the forward motion of the primary carriage. The said mechanical means may comprise a substantially triangular cam 55, 56, the part 56 being detachably mounted on the bed, and a roller 54 on the secondary carriage. Moving stock 25, e.g. metal bar or plate, on contacting the flag switch 24 energises a solenoid (not shown) causing the clutch 22 to drive the pinion 15 in engagement with a rack 30 on the underside of the primary carriage 16 and so move this carriage forward parallel to the stock. A roller 54 carried by the secondary carriage 40 engages the slot 59 of a triangular cam 55, 56, giving to the secondary carriage and cutter 48 a transverse motion towards the stock to sever it, followed by a transverse withdrawal as the roller 54 moves along the slot 57. At the extremity of the forward motion of the carriage 16, the roller 54 operates a limit switch (not shown) to disengage the clutch, and the carriage returns to its initial position under the action of compressed air in the cylinder 35 carried by the carriage 16 and having a hollow piston rod 33 attached to the bed 10 at 34 and through which compressed air enters the cylinder. The roller 54 may be kept in engagement with the operative face of the cam by a pneumatic buffer the cylinder 62 of which is carried by the primary carriage whilst the piston rod 64 is connected to the secondary carriage. The stock is gripped during the forward motion of the primary carriage by pneumatically operated clamps 45 on either side of the cutter 48. These are operated to grip the work-piece when the flag switch 24 is actuated to put its circuit into operation and operate a valve to admit air to the top of the cylinder 44 thus bringing down the upper members 45, 46 of the clamp. The clamps are released when the roller 54 operates the limit switch at the termination of the forward movement of the primary carriage, the air valve then admitting air to the bottom of the cylinder 44 to raise the members 45, 46.

Title: Improvements in the culture of moulds
IPC: C12N1/14
Filed: 1945-06-08
Abstract: In the manufacture of chemical substances such as citric acid by the growth of moulds upon the surface of nutrient liquid media, the mould is added to the medium in conjunction with an aqueous emulsion of an oil which has a positive spreading pressure on water and which breaks upon being mixed with the medium.  In an example, citric acid is produced by the growth of Aspergillus niger on a solution containing glucose, ammonium nitrate, potassium dihydrogen phosphate and magnesium sulphate to which has been added an alkaline aqueous emulsion of air oxidized paraffinum liquidum B.P. containing small quantities of octadecyl alcohol and crystal rosin.ALSO:In the manufacture of chemical substances by the growth of moulds upon the surface of nutrient liquid media, the mould is added to the medium in conjunction with an aqueous emulsion of an oil which has a positive spreading pressure on water and which breaks upon being mixed with the medium.  The breaking of the emulsion tends to carry the inoculum to the surface of the medium. The oil may be castor oil, stand oil or an air oxidised paraffinum liquidum B.P., emulsification being optionally effected with the addition of oleic acid, sodium rosinate or octadecyl alcohol together with rosin in a valve homogeniser.  The method may be applied to the manufacture of penicillin by the culture of Penicillium notatum, kojic acid by Aspergillus effusus, citric acid by Aspergillus niger, glutinosin by Metarrhizium glutinosum claviformin (patulin) by Penicillium claviforme and gliotoxin by Trichoderma viride.  In examples the nutrient media are made up by mixing substances chosen from corn steep liquor, lactose, glucose, sodium and ammonium nitrates, ammonium tartate, potassium chloride, dipotassium hydrogen and potassium dihydrogen phosphates, magnesium, ferrous zinc and copper sulphates, phenylacetic acid, boric acid and caustic soda.

Title: Improvements in and relating to non-numerical switching arrangements for automatic and semi-automatic telephone systems
IPC: H04Q3/00
Filed: 1928-05-18
Abstract: 317,521. Standard Telephones & Cables, Ltd., and Wright, E. P. G. May 18, 1928. Automatic exchange systems.-In systems using primary and secondary backward hunting switches in tandem, the secondary switches hunt first to find idle primary switches with access to the calling line. Two secondary switches may take idle primary switches into use to find the calling circuit arrangements being made to free the unused switches immediately the calling circuit has been extended to a selector. The relays controlling the switches are all located in a controller switch CS. When a call is made relay L closes a circuit for a common starting relay A which completes a circuit for relay J in all the free control switches CS. Relays H and BB pull up in series (J3 and N) causing the selector control SO to test busy and the secondary switches, preselected by CS, to start hunting for the primary switches (SFDM, J1, E1, F1, K1, H1). When a secondary switch reaches a free primary switch with outlets to the line calling, relay E operates (D1, H2, CC, A1 and HA) allowing F to pull up and the primary switch starts hunting for the calling line (EDM, B1, F1, K1, HI). A second secondary switch can, if one is free also engage a free primary but when relay E of the second switch has operated, relay H5 pulls up and releases the relays J of the remaining control switches those already in use being locked by relay H over F3. The secondary switches are provided with an additional wiper B which guards engaged primaries (KB1, HB1, HB5, HB4), a secondary switch stepping on one of these lines would complete a circuit for relay D which prevents relay E from operating. Immediately the calling line is reached relay B operates in series with relays KA and KB. Relays L, A, HA and E relapse, relay K pulls up (131, F1, K1, HI) and the relay F falls back. Relay KB extends the subscribers line through to the im. pulsing relay AA which energizes, short circuiting relays H and B. Relay K releases and G pulls up via H3 and D2, the earth being provided over a chain of selector and selector controls. The control switch CS steps (G3, H3) until a free selector connected to a free control is reached when relay H is energized breaking the circuit of relay G and relay K breaks the the circuit of relay B. Relay H relapses and the control switch remains connected to the free circuits. If there are no free selectors and selector controls, relay C operates (but not relay G) recording a call on the overflow meter M. Specification 295,421 is referred to.
