Patent GB-1289249-A (GB)
IPC: G06F7/78
Filed: 1971-05-05
Abstract: 1289249 Associative store INTERNATIONAL BUSINESS MACHINES CORP 5 May 1971 13265/71 Heading G4C A digital data storage system comprises an associative store comprising associative registers for storing data items, wherein in operation registers not being used for storing data are identified by sequential numbers belonging to a cyclic number (i.e. 1, 2 ... n, 1, 2 ... n &c.) sequence of length equal to the number of registers in the store, a different number being stored in each unused register, there being means for storing in a register from which a data item is unloaded, before a further data item is unloaded from the store, the number next in the cyclic sequence to the highest number identifying a register not in use. In the two embodiments the system is used for storing data in transit between various devices, e.g. multiplexed telecommunication terminals, disc files, tape reels &c. controlled by a microprogram store (Fig. 1, not shown). Data associated with each device is unloaded in the order of loading and the storage space used for each device is easily variable. In one modification (Fig. 5, not shown) when a fixed number of words have been stored this is labelled as a data buffer, further buffers are created if needed, and these buffers are normally unloaded in the order of loading though a priority system may be used. The associative store may be as described in Specification 1,186,703 and preferably comprises a data section 10 and a tally section 20 having registers 11, 21 respectively. These have control fields 12, 22, an identifier field 13, sequence fields 12, 24, and data fields 15, 25 each comprising bytes 1-3. Control signals arrive via lines 16, 26 and numbers via line 17. The registers are represented by their contents in horizontal lines and are either in use (the first 8 registers of store 10) or not (the remaining registers with a 1 for their leftmost numeral, referred to as the free list). The lines in the free list are not necessarily physically adjacent, and the lines in use (e.g. a data buffer) are described (Figs. 3a, 3b, not shown). Each data item is identified as belonging to a buffer by the identifier field, its position is given by the sequence field and unloading is operated by the first in/first out principle using an unload marker in the control field. When data is loaded into a buffer the sequence number of the data marked by the load marker is found and incremented. The incremented sequence number, together with a new load marker, is placed in the sequence field of the line into which data is being loaded. A record of which lines store data and which are on the free list is maintained by means of load and unload tallys in store 20, the stores 10 and 20 operating in synchronism under control of the microprogram store. In suggested modifications the tally store can be dispensed with, the equivalent data being held in separate registers. The circuitry can be made of integrated circuit chips.

Title: Zoned elevator control system including an arrangement for  controlling the operation of cars in response to the level of  traffic in the zones
IPC: B66B1/20
Filed: 1970-12-02
Abstract: 1328392 Zoned multicar elevator control OTIS ELEVATOR CO 2 Dec 1970 57315/70 Heading B8L The floors of a building are divided into zones L, 1-3 and a car is normally assigned to each zone, and sensitive only to calls from that zone, providing service therein. Should the demand for service in any zone exceed the average demand for service in all zones by more than a predetermined amount, more than one car may be assigned to that zone, and any unassigned car sent towards the zone. Operation.-Each car, a, b, c, d has a pair of associated zoning brushes ZBa, CZBa-ZBd, CZBd mounted on its selector, the brushes completing circuits via zoning contacts CZa- ZCd; CZCa-CZCd in the various zones L, 1-3, corresponding to floors 1; 2-6; 7-11; 12-16, as shown. Should, for example, car a move into an unoccupied zone, say 2, a circuit is completed between lines L10 and L11 via brush ZBa and (7-11 ZCa) contact 7-11 ZCa, the ignition of neon tube N1a rendering controlled rectifier SCR1a conductive, operating assignment switch CAZa to assign car a to zone 2, and switch G2Z to render car a sensitive only to calls in zone 2. Since the voltage at contacts 7-11 ZCa-7-11 ZCd is now low, passage of a second car for example b into zone 2 will not lead to its assignation there, since the neon tube N1b cannot ignite. A high demand for service in zone 2 causes the opening of contacts Z2R3 after closure of contacts Z2R9, deenergization of switch G1Z allowing cars in the zone below to respond to calls in zone 2, and the closing of contacts Z2R10, so that any further car c, for example, entering zone 2 is assigned there via brush CZBc, contacts 7-11 CZCc and assignation switch CAZXc. Unassigned cars may be sent towards zone 2 under such high demand conditions. Determination of high demand in a zone, for example 3, see Fig. 2 (not shown).-Each call for service in the zone causes a resistor, e.g. (CRDT) to be connected between lead (QZH3) and earth via transistor (TDT), so that transistor (T1) connected to (QZH3) in comparator (C3) conducts in proportion to the total number of calls in the zone. The output of (T1) is averaged with corresponding outputs of comparators (C1, C2) from the other zones in the averaging cricuit (AV), whose output, from transistor (T5), modified by (T6) to set the predetermined amount via variable resistor (RE1) is fed to (T2) in comparator (C3). When the demand for service in zone 3 exceeds the average by at least the predetermined amount, (T2) and (T3) conduct energizing relay (Z3R) via driver (D3), thus causing operation of contacts Z3R8, 23R9 and 23R10. Resistors (RC1-RC3), or (CRDT) &c. respectively can be adjusted to give different preferences to different zones, or floors respectively. The circuitry may be realized with semi-conductor switching, instead of relay, circuits.

Filed: 1972-04-07
Abstract: 1335009 Rotating cylinder block engines BEKAMA A G and P VON ESCH 7 April 1972 16222/72 Headings F1A F1B A multi-cylinder engine comprises a stationary central shaft 3 having passages and control ports which permit the supply and discharge of a propellant fluid, a cylinder block G1 rotatably mounted on the shaft and in which are formed cylinder bores 1 and control passages aligned with the control ports, each bore containing a reciprocating double-acting piston operatively connected to a crank shaft which carries a pinion meshing with a sun gear fixedly connected to the stationary shaft. An eight-cylinder engine in which the layout is similar to Fig. 1 comprises four cylinder bores 29 and four bores 12 in each of which a crankshaft is journalled. Each crankshaft includes a crank and a crankpin which projects into a double-ended piston which reciprocates in the cylinder bore. Each crankshaft also carries a pinion which meshes with a sun wheel 21 that is secured to a stationary shaft 19. The block 10 in which the cylinder bores are formed is mounted on the shaft 19 by a bearing 45. There is a 4:1 ratio between the sun wheel and pinions and the block 10 carries a plate 14 which supports the outer ends of the crankshafts and also carries a support 15 integral with an output shaft 16. A rod 47 secured to the shaft 16 drives a lubricating oil pump 50 and a contact breaker cam 46. H.T. from the two ignition coils 26 is conducted to a distributor plate 24 and hence to sparking plugs 27. Fuelair mixture from a carburetter 22 is fed to longitudinal passages in shaft 19 and reaches the cylinder bores by way of passages 30 which are aligned with ports formed in the periphery of the shaft. The passages 30 also align with ports leading into exhaust passage 23. Cooling water circulates through passages 54, 55 and 57. In an engine arranged as shown in Fig. 2 in which the cylinder bores are parallel to the mainshaft the crankshafts 205, Fig.11, (not shown) each carry a bevel pinion 204 which meshes with a sun wheel 203. The crankpin runs in a steellined slot in the piston and the crankshaft is supported at both ends in ball-bearings. The engines operate on a four-stroke cycle and the gear ratio between the sun wheel and pinions is 4:1, so that with four double-acting pistons, there are sixteen power strokes for each two revolutions of the cylinder block around the main shaft, equivalent to an eight cylinder engine. Typically, the cylinder bore is 41.5mm, stroke 20mm, capacity of each cylinder 25 cu. cm, total capacity 200 cu. cm and the speed of the output shaft 3, 000 r.p. m. The engine may also be operated as an hydraulic motor.
