Title: Multipacks of containers
Inventor: GRIFFIN CHRISTOPHER JOHN
IPC: B65B17/02
Filed: 1982-09-10
Abstract: A multipack comprises a plurality of containers such as cans (10) tightly held in an array by a sheet plastics coupler (11) which has apertures through which the tops (9) of the containers protrude. The tops of the containers are provided with end closures and the multipack includes a cover attachment (8) formed from a blank of heat-sealable sheet material having a plane portion which covers these end closures, and a plurality of tabs (44) which are integral with the plane portion and are folded downwardly along a crease line (45) and connected by heat sealing (46) to the coupler at the outer periphery of the multipack. This configuration is easier to produce than known arrangements and is less likely to become damaged during storage and handling. An apparatus for the high speed attachment of said blanks to said couplers comprises conveyors for transporting arrays of coupled containers (65) through the apparatus, an applicator (80) for removing blanks (82) from a magazine (81) and depositing them on respective said arrays of containers, means for directing hot gas onto the blank tabs (44) and the coupler to render them heat-sealable together, folders for bending the tabs downwardly against the coupler and means for pressing the tabs against the coupler to heat seal the same together. <IMAGE>

Title: Clutch release bearing assembly
Inventor: BRANDENSTEIN MANFRED
IPC: F16D23/14
Filed: 1982-12-13
Abstract: A clutch release assembly comprises a sliding sleeve (10) with a radial flange (11) and an abutment ring (13). To reduce wear at the contact surfaces of the abutment ring (13) and the clutch diaphragm-spring tongues (22), an elastically axially loaded bearing (20,21) is provided. The bearing keeps the bearing surfaces (12, 15) of the flange (11) and ring (13) apart under low load until the abutment ring (13) is rotating with the clutch. Under higher loads, when the clutch is fully disengaged, the elastic loading of the bearing is overcome and the bearing surfaces (12, 15) contact each other. The bearing (20) can be a plain or sliding bearing as shown or a rolling bearing, the elastic loading being provided by a corrugated annular spring (21) or a conical annular spring, respectively. <IMAGE>

Title: Apparatus for controlling the speed of an elevator
Inventor: TANAHASHI TORU
IPC: B66B1/30
Filed: 1984-12-21
Abstract: The invention controls an AC electric motor IM that drives the cage 9, by using a power rectifier 2 made up of thyristors and a power inverter 4 made up of a transistor and a diode. A speed instruction 11 for the cage is compared at 12 with a detected speed from 6 to produce an output instruction signal voltage 12a for said power rectifier and a slip frequency instruction signal voltage 12b for said power inverter. The control circuit controls the phase of said power rectifier relying upon the output instruction signal and controls the pulse-width modulation of said power inverter relying upon said slip frequency instruction signal, the control circuit comprises a voltage detector 26 that detects the voltage of the AC power source, and a minimum value select circuit 27 that receives the output of said voltage detector as a first input, that receives said output instruction signal as a second input, that compares these inputs, and that produces a signal of the same level as the signal of the lower level. The output of said minimum value select circuit is produced as a corrected output instruction signal to control the phase of said power rectifier. The inverter is controlled so that its output voltage measured at 17 equals the sum of the actual speed voltage and the slip frequency voltage. <IMAGE>

Patent GB-2176034-A (GB)
Title: Control apparatus for actuators
Inventor: RELF RICHARD STEPHEN
IPC: G09B9/28
Filed: 1985-05-29
Abstract: A flight controls simulation computer 16 controls three actuator assemblies 18, 19 and 20 for primary flight controls, and another actuator assembly 21 for a secondary flight control. The computer 16 is a multi-microprocessor based computer, each actuator assembly being controlled in accordance with a predetermined mathematical model implemented as a program in a channel processor 32 for the respective actuator assembly. The channel processors 32 receive data via either 16-bit converters 28 or 12-bit converters 28' from analogue signals 23 or 25 from the actuator assemblies. Control commands issued by the processors 32 are converted into analogue signals by the circuits 28 or 28'. Data relating to variables in the respective mathematical models are entered from a host computer interface 17 to a data link interface 35. A crosstalk processor circuit CPUX transfers this data to first areas of double-buffered RAM in respective channel I/O circuits 30 or 30', while the channel processors 32 have access to second areas of the respective RAMs. The first and second areas are interchanged at regular intervals so that the host interface 17 can be supplied with updated data from the channel processors 32, and the channel processors 32 can receive new values for the variables in the respective mathematical models. <IMAGE>

Title: Flange valve
Inventor: MOAKES DAVID PHILIP
IPC: B65D77/06
Filed: 1985-06-17
Abstract: A flange valve for a liquid dispensing bag has a valve head (2) which seals against the flange seating on the flange body (1).
