[Also in Divisions H1 and H2] For instructional purposes a plurality of electrical modules are connected together serially, each module comprising at least four terminal points on one or two surfaces which are so interconnected within the module as to form through conductors for the power supply to the assembly and/or to enable the module to perform a circuit function. In the frequency generator assembly shown in Fig. 2, modules B, D, H, L comprise circuit components, and have four terminals (not all of which are used) on each of two opposite sides which provide input and output terminals for the components and a through line for each pole of a battery A. The circuits within the modules may be constructed conventionally or by printed circuit, thick film, thin film or integrated circuit techniques. Module C comprises only conductive connections between its terminals. Modules which can be inverted without affecting the circuit are denoted by vertically symmetrical letters such as H; other modules may be inverted to vary their effect, e.g. C. Alternatively, the modules may be marked by a number or colour code. To prevent damage to components due to wrong polarization, a protective component, such as the diode in module D, may be provided; alternatively, the current flowing following a wrong connection may be made zero or harmless by the construction of the modules, as in Fig. 4 (not shown). The modules need not be assembled in line; Fig. 5 (not shown) depicts an arrangement which includes a redirecting module (U) comprising terminals interconnected to permit a 180 degrees reversal of direction of assembly. Connections between terminals of adjacent modules may be made by plug-jacks, which may be embodied in modular form; or the module terminals themselves may comprise alternate plug and socket contacts to permit direct connection therebetween.

Abstract: 1365028 Penicillin salts MERCK & CO Inc 13 Nov 1972 [18 Nov 1971 7 Aug 1972] 52374/72 Heading C2A The novel probenecid salt of D-(-)-α-aminobenzyl-penicillin pivaloyloxymethyl ester is prepared by reacting together in a liquid medium probenecid or a salt thereof and the said penicillin ester or a salt thereof. In the preferred process, the liquid medium is a solvent for the reactants and a non-solvent for the desired product, so that the latter crystallizes out from the reaction medium. This is achieved by using methanol, ethanol, propanol or isopropanol as the medium in which are reacted essentially equimolar amounts of an alkali metal (e.g. potassium) salt of probenecid and a mineral acid (e.g. HCl) salt of the penicillin ester, whereupon the inventive salt crystallizes out and the by-product (KCl) remains in solution. Pharmaceutical antibacterial compositions comprise the said novel salt together with a non- toxic pharmaceutical carrier. The compositions may be in unit dosage solid or liquid forms and are preferably for oral administration.

Abstract: 1,185,650. Control of D.C. motors. LANSING BAGNALL Ltd. 20 Nov., 1967 [28 Nov., 1966], No. 53133/66. Heading H2J. [Also in Division G3] During normal driving operation of a D.C. motor 17, which is supplied through a thyristor 12, a field winding 15 is not energized, but both field windings 14, 15, are energized in opposition when the motor is plugged. As the driving current through the armature tends to become excessive, a load winding 19 saturates a transductor core and reduces the impedance of winding 11 forming part of a potential divider network 30 between the primary stage 31 of a pulse generator and an output stage 32 which is associated with the trigger circuit of the thyristor 12. Accordingly, the application of trigger pulses to the thyristor is prevented when the core is saturated, the motor current being thus restricted to a desired value. When acceleration is required, the reluctance of the magnetic circuit of the transductor core is increased by withdrawing a movable core element which is coupled with a control pedal. A larger current through the load winding 19 is then required before the core is saturated. The armature connections are reversed for braking by changing-over the switches 16, 16a, so that current passes through the field winding 15 and diode 24. The total field excitation is so reduced to keep the braking current at a safe value. In another arrangement, the motor has two series field windings, each capable of driving the motor in a selected direction and being associated with an individual control switch. When one switch is open, current through the associated field winding is blocked by a diode. To reverse the motor, both switches are first opened and then the previously-opened switch is closed, so that the field windings are energized in opposition during the braking period. In a further embodiment, on a stable multivibrator feeds pulses to the network 30 and to a second thyristor, respectively. The closure of a starting switch raises the potential of a heat sink and the second thyristor is triggered to charge a capacitor associated with a transformer. When the first thyristor becomes conductive to energize the motor, the heat sink potential falls to reverse the charge on the capacitor whereby the second thyristor is turned-off. Afterwards, a' trigger signal is applied to the second thyristor and the capacitor is discharged to turn-off the first thyristor.
