Title: Improvements in or relating to matrix memory systems
IPC: G11C11/06
Filed: 1958-10-14
Abstract: 852,397. Circuits employing bi-stable magnetic elements. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct.14, 1958 [Oct.17, 1957], No. 32736/58. Class 40 (9) [Also in Group XIX] In a matrix of elements of magnetic material having a rectangular hysteresis loop each being magnetically coupled to one conductor of a first group and one conductor of a second group, the magnetic state of an element is changed by variation of the electrical state of the conductors coupled to the element while the remaining conductors are short-circuited. As shown, magnetic cores K 11  to K 44  are coupled to conductors H 1  to H 4 , V 1  to V 4  which form the primary windings of transformers CH 1  to CH 4 , CV 1  to CV 4  respectively. Each secondary winding is centre-tapped to earth and the ends are connected to the emitter and collector of a transistor e.g. TH3. When conducting the impedance of the transistor is very low and this is stepped down by the transformer towards the associated conductor e.g. H 3  so that the impedance is very low and forms a short circuit. BH 3  is a source of positive potential rendering the transistor non-conductive and thus raising the impedance of the associated conductor. All the cores are coupled to conductors SH, SV, which are connected to a terminal SB and to earth, in such a way that currents through SH SV act magnetically in support of each other at the cores. Conductor SH is also arranged so that there is strong magnetic coupling with conductors H 1  to H 4  and SV with V1 to V 4 . The coupling may be assisted by the use of auxiliary coupling cores HK of high-frequency magnetic material. Information is stored in core K $4  for example by applying potential to BH 3 , BV 4  thus raising the impedance of H 3 , V 4  and by supplying a pulse of the required polarity to SB. Reading out from a core without destroying its magnetic state may be done by eliminating the short circuit on its coupled conductors and supplying an alternating current of small amplitude through terminal SB. In a simplified arrangement where synchronized pulses each of half the strength required to change the remanence state of a core are supplied to the conductors coupled to the core (Fig. 1, not shown) an alternative method is to supply a single full-strength pulse to one of the conductors while the other is at a high impedance. Change of remanence of the other cores coupled to the conductor carrying the pulse is prevented by the reaction currents set up in the short-circuited conductors also coupled to these cores.

Title: Motor and switch assembly
IPC: H02K11/00
Filed: 1974-07-24
Abstract: 1473699 Mechanical switches MABUCHI MOTOR CO Ltd 24 July 1974 [31 July 1973 (4)] 32756/74 Heading H1N A small motor, battery and switch assembly comprises a generally tubular casing 2 receiving the motor 1 therein, a generally tubular casing 4 adapted to receive a battery 3, 3 therewithin, a first contact 13 connected to the motor 1 and carried by casing 2, a second contact 18 carried by the casing 4, and a battery contact 11 connected to the other terminal of motor 1; the casings 2 and 4 being adapted to be axially aligned and mutually coupled at their ends with one terminal of the battery 3, 3 engaging contact 11 and its other terminal connected to contact 18, and so that the casings 2 and 4 are relatively rotatable to bring the first and second contacts 13 and 18 selectively into engagement to complete a circuit between the battery 3, 3 and the motor 1. The assembly may be used to drive a propeller 5 of a model airplane, the assembly being mounted by sliding ridges 26 on casing 4 on to a mounting rib (33, Figs. 4A and 4B, not shown) or by bayonet-type fitting into a nacelle (35, Fig. 6, not shown), or with a nosecap covering motor 1 (Fig. 8, not shown). The assembly may be used in a toy motorboat by mounting ridges 26 on to a mount (42, Fig. 7, not shown). The whole assembly may be fitted into a further two-part casing (61, 62, Figs. 17 to 20, not shown) to form a hand held fan. A gear assembly may be added and comprises a support member (73, Figs. 26 to 29, not shown) attached to the motor casing to carry an output shaft (77) parallel to the motor axis and having a gear-wheel (76) thereon engaging a pinion (83) on the motor shaft 7. The contact 13 fits into a recess 17 in casing 2 to prevent relative rotation between the motor and casing, and the contact 18 is held by a tongue 23 bent into recess 25 in the flange 24 on easing 4. This flange 24 fits into the end of casing 2 to provide the rotatable switching coupling between the casings. The contact 13 has a tongue 15 which, with a tongue (45, Fig. 15, not shown) on the part 19 of contact 18, provides terminals for connection of an external switch (48, Figs. 13 and 16, not shown) where access to the casings 2 and 4 is difficult and their mutual rotation inconvenient. A handle 27 may be fitted between ridges 26 to assist in rotating casing 4 where casing 2 is fixed (as in Fig. 2, not shown) or a handle 28 may be attached to motor 1 for use where the casing 4 is fixed. A key 51 may be inserted through recess 91 in casing 2 and a similar recess in the casing 4 to lock the cases against mutual rotation when an external switch is used (Figs. 13 to 16, not shown). This key 51 protrudes between contact 11 and the battery to form a power take-off lead (46) which, with the tongue (45), allows the battery to be used to energize an auxiliary device (53).

Abstract: 641,377. Gas turbine plant. MINISTER OF SUPPLY, BOWDEN, A. T., and PARSONS & CO., Ltd., C. A. Dec. 12, 1947, No. 32757. [Class 110(iii] A gas turbine plant for road vehicles comprises a compressor a driven by a first stage turbine rotor c and a power shaft i driven by a second stage turbine rotor d through gears f. The separate shafts b, e may be coupled through gears o, quill shaft m, gears l and a free-wheel clutch k, j. The clutch permits the drive system d, e, f, i to slow down regardless of the speed of the compressor system, but if the drive system overspeeds it drives the compressor system through the clutch and the latter system then acts as a brake. The clutch may be of any type which permits the element k to overrun and prevents the element j from overrunning.

These compounds may be obtained by reacting the appropriate diacid, anhydride or ester with a substituted hydrazine, or by reacting a compound of the invention in which R1 or R2 is hydrogen with an appropriate halide, sulphonating agent or acylating agent, in the latter case a free hydroxy group may also be acylated.  In the case of compounds of the first general formula above, wherein R1 and/or R2 represents a hydroxyalkyl group, the group may be converted to a chloroalkyl group by reaction with thionyl chloride, and the chloroalkyl group may then be reacted with an appropriate amine to form an alkylamino group.  Further, compounds in which R and R1 are both hydrogen atoms may be converted by direct alkylation, for example ethyl pyridine derivatives may be prepared by alkylation with vinyl pyridine.  Pharmaceutical compositions having antiinflammatory properties and containing these compounds as the active ingredient may be in the form of solutions in sterile pyrogen-free water for injection and as ointments, creams and lotions for topical application.

Dice; games of chance.-An appliance whereby dice are " thrown " mechanically within a closed space comprises dice-projecting crank levers each of which is operated bv a spring-returned thrust rod acting in an approximately vertical direction, the thrust rods being located in a common guide tube and terminating in a common striker knob. A dished base 1 covered by a glass bell 2 supports a central guide tube 3, and the space within the bell is divided into three equal compartments by gauze partitions P. In each compartment is arranged the figure of a football player with a pivoted leg 7. An arm 10 of the leg passes through a slot in the central tube 3 and engages a vertical thrust rod 13 extending into a hole 15 in a knob 14. Slides 16 in the knob may be pushed across the holes 15 above the thrust rods. When the knob is struck by the hand of a player the thrust rods actuate the legs 7 so as to project the dice 6 up the sides of the base. One or more of the dice may be omitted from the play by pulling out the corresponding slide or slides 16 thereby avoiding operation of the corresponding thrust rod or rods. Springs 19 beneath the feet of the vertical thrust rods and a spring 18 beneath the knob 14 restore the mechanism after actuation. The toes of the legs 7 are loaded with lead. In a modified arrangement of the knob 14 and vertical guide rods, additional pins in the knob pass through slots in the tops of the guide rods and raise the rods when the knob rises.
