Title: Improvements in or relating to cephalosporin compounds
Inventor: EARDLEY STEPHEN
IPC: C07D501/04
Filed: 1967-08-21
Abstract: 1,241,657. Preparing 3-substituted-methyl cephalosporins. GLAXO LABORATORIES Ltd. 6 Aug., 1968 [21 Aug., 1967], No. 38494/67. Heading C2A. Cephalosporin analogues having a group or atom derived from a nucleophile on the exocyclic carbon atom at the 3-position are prepared by reacting a 7-amino- or 7#-acylaminocephalosporanic acid (or derivative thereof),  having a group -CH 2 X at the 3-position, with a nucleophile to effect nucleophilic displacement of the group X by a group or atom derived from the nucleophile, the group X being the residue of an acid HX which acid has a pKa of not more than 4 and in which acid the group X does not contain a sulphur atom linked to the hydrogen atom H. Cephalosporanic acid derivatives used as starting materials may be the salts, esters or anhydrides. Such esters include those with carboxyl-protecting groups such as diphenylmethyl; #,#,#-trichloroethyl and tert.-butyl radicals. The group -CH 2 X may be halomethyl (e.g. chloro-, bromo- or iodomethyl), or an ester group -CH 2 -O-A wherein the esterifying group A is derived from formic acid, a haloacetic acid, a methoxy-, alkylthio- or cyano-acetic acid, glyoxylic acid, phenylpropiolic acid, a hemi-ester of malonic or oxalic acid, or phenylglyoxylic acid substituted in the ring with halogen, methyl or methoxy; or the group X may be isocyanato. Numerous nucleophiles are mentioned, including trialkylamines, pyridines, nitrogen heterocyclic amines containing other heteroatoms, cyanides, pyrroles, indoles, acetylenes, acetoacetic and malonic esters, cyclohexane-1,3-diones, thiourea, substituted thioureas, thioamides, thiosulphates, alkanols, phenols and water. The reaction is suitably effected in a polar medium (which may be the nucleophile itself) at pH 5-8 and between 0 and 120 C. Novel cephalosporins of formula wherein each of the groups B is a C 1 -C 6  alky<SP>1</SP> group, or the groups B together with the adjacent N atom form a thiazole ring which may be substituted, are prepared by the aforesaid process.

Title: Improvements in or relating to blowers
IPC: F04D29/42
Filed: 1962-10-12
Abstract: 968,529. Centrifugal blowers. K. PRESTL. Oct. 12, 1962 [Oct. 12, 1961], No. 38802/62. Heading F1C. A motor-driven blower comprises an impeller arranged to rotate in a housing and to draw in axially and expel approximately tangentially through a discharge opening in the housing, which also has two suction openings in its axially opposite walls, and the impeller has three chambers lying next to one another axially, of which the middle one communicates with one of the two outer chambers through an opening in an intermediate wall; the impeller being located on the motor shaft by means of the other, closed intermediate wall.

Compartment III draws in air through port g in a side wall d of the casing, while compartments I and II draw in air through port h in the opposite side wall, plate k being apertured at l to permit entry to the compartment II. The impeller discharges approximately tangentially through an opening o having a breadth as viewed in Fig. 2 of about one and a half times the impeller diameter, the portion X of the breadth which is offset to one side of the vertical through the impeller axis being approximately equal to the impeller diameter.

Title: Internal combustion engine coil ignition systems
IPC: F02P3/04
Filed: 1964-09-24
Abstract: 1,064,857. Ignition systems. GENERAL MOTORS CORPORATION. Sept. 24, 1964 [Oct.17, 1963], No.38938/64. Heading F1B. In an I. C. engine coil ignition system the primary winding of the coil is energized from a D.C. source through a circuit including a three electrode semi-conductor normally biased to its conductive state, but periodically biased to its non-conductive state by a device operable in synchronism with the engine. The potential of a gate 58 of a controlled rectifier 54, of the type which can be switched on or off by the gate, is made positive with respect to the cathode 60 by a potential divider 81, 77 to make the controlled rectifier conductive. The controlled rectifier has a breakdown rating of approximately 500 to 700 volts. When interrupter contacts 22, 24 are closed the voltage induced in the secondary winding 68 of a pulse transformer 64 is of such polarity as to assist rendering the controlled rectifier conductive. When the contacts are opened a voltage of reverse polarity is induced in the secondary winding 68 sufficient to drive the gate 58 negative with respect to the cathode and render the controlled rectifier non-conductive. This opens the circuit of the primary winding 38 of ignition coil 36 to induce a high voltage in the secondary winding 40 connected through a distributor 30, 32 with the spark plugs 46. When the induced voltage of reverse polarity of the pulse transformer 64 has dissipated, the controlled rectifier will again become conductive even if the contacts 22, 24 are still open. The resistors 67, 77, 81, transformer 64 and controlled rectifier 54 may be connected together to form a single unit and added to an existing conventional ignition circuit. The connection 71 may instead be made between the resistor 67 and the primary winding 66 of pulse transformer 64. The conductor containing resistors 77, 81 may be omitted and a capacitor arranged between an earthed secondary winding 68 and the gate 58 or the secondary winding 68 and earth; in the latter case a resistor is arranged in parallel with the capacitor. Thus, the inter-action of the voltage induced in the secondary winding 68 and the charging and discharging of the capacitor renders the controlled rectifier non-conductive when the contacts 22, 24 open but capable of becoming conductive again before they re-close. In other arrangements, Figs. 5 and 6 (not shown), a PNP or a NPN transistor is used, instead of the rectifier, in a modified circuit which may include a Zener diode connected across the transistor to protect it against voltage transients.

Title: Process for making bakery products
IPC: A21D8/02
Filed: 1963-10-07
Abstract: In making bakery goods exemplified particularly by bread and cakes, the gluten in at least a part of the flour used in the dough or batter is fatigued or made to fail, i.e. the dough is, by working, caused to lose its capacity for forming a "dough ball", at which stage there is a sharp decrease in the force necessary to work the dough.  The total time taken to make the goods can be reduced and the resulting bread and cakes have a longer shelf life.  All of the dough may be so worked, or additional flour may be added to the dough mix after the fatigue point has been reached, but the amount of additional flour should not exceed the original amount in the dough. Specific examples of the process as applied to bread making and cake making are given.
