In the example of Fig. 1 the post 4 is supported on a frame part 43 having a lower bearing 14 in a second frame part 10 carrying a power drive 16 for rotating the frame part 43 and post 4 about the vertical axis Y, Y for isolation. The second frame part 10 is also pivoted at 17, 17 on a horizontal axis X, X whereby the circuitbreakers 1 may then be swung downwards to a maintenance position. In modifications the support frame may be moved horizontally on rollers whereby the circuit breakers may be moved to one or more positions to engage further pairs of fixed contacts (25), Fig. 7 (not shown), on insulating support columns (20). In other examples the circuit-breakers 1 and columns 4 may be isolated from one pair of columns 20, Fig. 12, by rotation through 45 degrees on the vertical axis or may engage a second pair of columns 20 by rotation through 90 degrees. At the 45 degree isolation position they may be swivelled downwards on the horizontal X, X axis as in the example of Fig. 1. In a further example, Fig. 23 (not shown), the column 4 may be lowered vertically along its own vertical axis (Y, Y) for both isolation and lowering to a maintenance position. Reference is also made to swivelling the column 4 on a horizontal axis arranged above the circuit-breakers which thereby move in the manner of a pendulum.

Abstract: 954,571. End stops for sliding clasp fasteners. LIGHTNING FASTENERS Ltd. Nov. 10, 1961 [Nov. 10, 1960], No. 40315/61. Heading E2S. In a sliding clasp fastener having two interlocking series of fastener elements an end stop is secured to the fastener elements in at least two positions separated longitudinally by at least two fastener elements of one and the same series thereof. As shown in Figs. 1 and 2 the end stop 7, is a bottom stop in the form of a staple having four legs arranged in pairs 8, 9, 10, 11 which straddle the longitudinal centre line of the fastener and the legs being longitudunally staggered. The legs pass through gaps between longitudinally adjacent fastener elements. With this construction the width of the stop is slightly less than that of the interlocked elements. In a modification for use with elements made of a filamentary plastics material the stop is similar but is applied so that the elements embraced by it are compressed to make the thickness of the end stop when in position the same as that of the elements. The construction can also be applied to a top stop. Reference has been directed by the Comptroller to Specification 898,772.

Title: Bacterial compositions for the regeneration of the intestinal microflora
Inventor: LABOUREUR PIERRE
IPC: A61K35/747
Filed: 1963-10-15
Abstract: A bacterial composition for the regeneration of intestinal microflora comprises a balanced association of bacterial strains which are saprophytic microflora, combatant to pathogenic yeasts and resistant to antibiotics under the conditions within the human intestine; the bacterial association should preferably incorporate strains capable of secreting enzymes and capable of proliferating in the presence of bile products.  The composition may comprise (i) a Lactobacillus strain such as L. brevis, L. bifidus or L. acidophilus, (ii) a Bacillus strain such as B. subtilis, B. mesentericus, B. pumilis or B. megatherium, and (iii) Aerobacter aerogenes, Escherichia coli, Escherichia interme dium or Pseudomonas fluorescens migula.  A preferred bacterial composition includes 50-60% of Lactobacillus brevis buchneri, 20-30% Bacillus subtilis and 10-25% of Aerobacter aerogenes; equal proportions of the three stains may be employed. The strains may be rendered more resistant to antibiotics and to pathogenic yeasts by seeding to transplanting the strains through a series of culture media containing antibiotics (specified) or pathogenic yeasts (particularly Candida albicans).  The strains should desirably be resistant to sulphamides (specified). Stated proportions of the bacterial compositions may be compounded in a pharmaceutical carrier.

Title: Circuit arrangement for varying the remanent flux in a magnetisable element
IPC: H01F13/00
Filed: 1960-11-28
Abstract: 902,382. Circuits employing multi-stable magnetic elements. STANDARD TELEPHONES & CABLES Ltd. Nov. 28, 1960 [Dec. 2, 1959], No. 40761/60. Class 40 (9). In a storage core which has several discrete operating states and is switched from one state to the next by a current pulse of predetermined duration, the switching current is permitted to increase to the value at which the rate of change of the core flux becomes substantial before its duration is controlled. This substantial change of flux commences at the knee of the hysteresis loop, and, as shown in Fig. 1, the current must be sufficient to provide a magnetizing force a to b before it can effect a timed change of flux from b to c, the core flux thereafter reverting to a remanent value d. The current pulse is derived from a constant voltage source, and the time constant of the circuit is such that the growth of current in the time period t1 to t2 is substantially linear, as shown in Fig. 2c. When the current produces the magnetizing force corresponding to b at time t2, a substantial change of core flux commences and the slope of the current characteristic decreases abruptly. The second derivative of this change of slope, as shown in Fig. 2e, produces a timing start signal which after a predetermined delay isolates the voltage source at time t3 and so terminates the flux switching. A suitable circuit for switching a double-apertured core 1 is shown in Fig. 3, in which a pulse of duration t0 to t4 is applied from a source 3 to a monostable multivibrator 5 so as to produce a rectangular pulse terminating at time tl. The trailing edge of this pulse starts a pulse generator 6 which applies a direct voltage to a core winding. The resultant current through the winding increases as shown in Fig. 2c, and when at time t2 the rate of growth abruptly changes, an output pulse is obtained from a doubledifferentiating amplifier 4 which is amplified and shaped at 7. The output from amplifier 7 starts a monostable multivibrator 8 to provide a pulse extending from time t2 to t3, and the trailing edge of this timing pulse switches off the pulse generator to terminate the flux-switching current in the core winding. During the period t1 to t4 that the source 3 is activated, the double-differentiating amplifier 4 is brought into use and an amplifier 2 connected to a second core winding is disabled.

IPC: G11B17/16
Filed: 1960-11-30
Abstract: 903,535. Record changers. STEIDINGER, O., and STEIDINGER, S., [trading as STEIDINGER KOMM-GES. GEB.]. Nov. 30, 1960 [Dec. 5, 1959], No. 41137/60. Class 40 (2). Means in a record changer for setting a pickup down in the run-in groove of a record comprises a sensing member 7 having two arms 30, 31, whereby the diameter of a record to be played is either detected while being released on to the turn-table or while disposed on the turn-table. When being lowered automatically, the record engages the arm 30 of the sensing member 7 and rotates it counterclockwise, as viewed in Fig. 1, and draws a 3-step abutment member 11, frictionally coupled to a crank 8, to a position corresponding to the size of the record detected. As the pick-up is fed inwardly, an arm 4 rigid with the pick-up engages one of the steps on the abutment member and determines the setting down position. As the pick-up is set down a cam on a cycling cam disc 5<SP>1</SP> withdraws the abutment arm 11 from the arm 4 by means of a slide 16 to allow the pick-up to traverse the record. With the commencement of a fresh automatic cycle at the end of a record the cam on disc 5<SP>1</SP> moves away from the proximity of slide 16 to restore sensing member 7 and associated parts to the initial position shown in Fig. 1, and a fresh cycle proceeds. When a fresh record however is placed manually on the turn-table the arm 30 of the sensing member 7 is unable to sense the diameter of the record, but a recordsteadying member 21 is then in its lower position and, through the medium of a lever 22, the sensing member 7 is raised so that the arm 31 thereon instead detects the size of the record, as it lays on the turn-table.
