Patent GB-759624-A (GB)
Title: Cephalosporin production
Filed: 1953-10-15
Abstract: A fermentation medium for use in the production of Cephalosporin-N, or mixtures of Cephalosporin-N and Cephalosporin-P, from a Cephalosporin-producing-mould of the species of which Cephalosporium I.M.I. 49137 is a member, comprises a nutritional substrate for said mould in admixture with an active proportion (defined) of d-methionine.  Racemic d-l-methionine may also be used, the quantity required being twice that of the d-isomer alone.  For Cephalosporin-N and a corn steep liquor, sucrose, ammonium acetate medium, the optimum concentration of d-methionine is 0.025 to 0.05 per cent by weight of the medium.  The d-methionine requirement of the mould varies with the medium.  The preferred medium is that disclosed in co-pending Specification 745,208.  Normally minimum requirements are a source of nitrogen and a source of carbohydrate.  It is preferred that the medium contains a source of organic nitrogen, e.g. fish meal, meat meal, casein, bouillon powder, dried autolysed yeast, malt extract, urea, soya bean meal, corn meal and corn steep liquor. Media containing d-methionine are less effective in the production of increasing yields of Cephalosporin-P than in the case of Cephalosporin-N.

Title: Pluggable memory module
IPC: H05K7/20
Filed: 1965-07-06
Abstract: 1,064,906. Component assemblies. CONTROL DATA CORPORATION. July 6, 1965 [July 8, 1964], No. 28542/65. Heading H1R. In a memory module, storage members are sandwiched between heat-conductive plates to form an assembly which is provided with driving means for the storage members, and connector means to enable the module to be plugged into a data processing machine. In Figs. 1, 3 (not shown), a rectangular heat-conductive housing (68), extending between front and rear plates (20, 10), e.g. of aluminium, accommodates two half-stacks of alternate heat-conductive plates (38) and memory planes (44, 52 &c.) separated by spacers (42, 46, 50 &c.) and held together by rods (36, 36<SP>1</SP>) whose threaded ends receive nuts (64, 66). The two half-stacks are connected by special spacers (56), a heat-conductive plate (58) being interposed. Driving units (60), each comprising spaced printed circuit boards and associated components, are mounted on the rods (36, 36<SP>1</SP>) between the half-stacks and the rear and front plates (10, 20); inhibit units (18) of similar construction are fastened externally to the sides of the housing (68). Recesses (12) in opposite sides of the rear plate (10) accommodate insulating boards (14), each of which has a plurality of plug-pins (16) extending therethrough. Each memory plane (Fig. 2, not shown) comprises a frame (24) having printed wiring (28) thereon and a central opening (26) therein. Vertical and horizontal drive wires, sense wires, and inhibit wires extend across the opening (26), threading magnetic cores and holding them in matrix formation. In addition to their cooling function, the heat-conductive plates (38, 58) screen the memory planes from one another.

Patent GB-482965-A (GB)
Title: Improvements in or relating to bottle or like capping machines
IPC: B67B3/04
Filed: 1936-10-20
Abstract: 482,965. Capping bottles &c. KING, G. E. Oct. 20, 1936, No. 28564. Addition to 448,666. [Class 125 (ii)] The bottle &c. capping machine described in the parent Specification is adapted for power operation, and, as shown, a horizontal shaft 11, mounted above the capping head and driven from a shaft in the machine base 7, carries a pair of cams 14 which engage spring-pressed rods 18 in the capping head and a cam 15 which engages the plunger 20 operating within the head; in the event of any unusual resistance being encountered by the capping head the springs 19 beneath the rods 18 yield and prevent damage to the machine or an incorrectly positioned bottle. The shaft 11 and capping head may be carried by a slide adjustable vertically on a standard so that the machine can be used to cap bottles &c. of different heights. The bottles are fed to the capping head along the table 8 by a reciprocating bar 26 carrying push levers 27 having rollers at their ends to engage the bottles, the levers being pivoted on hubs carrying springs which hold projections 28 on the levers against stops 29 on the bar 26 during the forward feeding movement thereof and the springs allow the levers to yield and pass over the bottles as the bar moves backward. A bent feeler lever 30 mounted on the end of a vertical spindle 31 is moved by a spring 33 across the bottle track, and when a bottle passes under the capping head, the lever is rotated against its spring so that a bevelled cam 34 on the spindle 31 moves into the path of a pin projecting from a detent lever 36 mounted on the capping head 4 and controlling the roller 5 on the table feeding the discs 1 into the capping head and holds the lever from rising with the feed table ; the lever 36 is thus tripped to release the roller 5 and associated feed slide and allow the entry of a new disc into the feeding head while if a bottle is not positioned under the capping head, the cam 34 is not in position to engage the pin and no forward feed of the discs takes place. The discs are severed from the band 1 by a blade on a lever pivoted in the capping head and controlled by a nose on a spring-controlled lever pivoted on the standard 9 of the machine. Specification 458,329 is referred to.

In a comparative experiment the catalyst is omitted, Numerous other catalysts are specified, derived from acetylacetone, methyl acetoacetate, ethyl acetoacetate or ethyl malonate, and an alkoxide, preferably a methoxide, ethoxide, propoxide or butoxide.  The aluminium compound may be prepared by reacting the corresponding aluminium trialkoxide with acetylacetone or alkyl acetoacetate or malonate.
