Patent GB-2107406-A (GB)
Title: Pneumatically operable electrical switching system
Inventor: JONES TERENCE ALFRED
IPC: F15B7/00
Filed: 1981-10-12
Abstract: A pneumatically operable electrical switching system includes a manually operable transducer for producing a pneumatic pressure or vacuum pulse for operating a remote receiver switch with spring loaded contacts such that the switch is retained in the appropriate position following the actuation pulse. The receiver may include two chambers to allow two-way switching to be achieved when a further transmitting transducer is incorporated in the system. The transducers incorporate a bleed valve to allow ambient pressure to be resumed between the actuating pulses. <IMAGE>

Title: Device for wrapping loads with stretchable wrapping material
Inventor: REDFEARN ALAN
IPC: B65B67/08
Filed: 1981-11-23
Abstract: In a hand-held device for wrapping a load with a web 28 of stretchable plastics film, a deflector strip 30 of rigid plastics material is attached to an upright 4 of the frame 1 of the device so that it is disposed in spaced relation with the roll 26 of the web and substantially parallel to the axis thereof. The deflector strip has a substantially straight edge 33 adjacent the roll and convexly curved surface 32 contiguous with the straight edge and extending away from the roll. When the web 28 is dispensed from the roll 26 it may be engaged against the straight edge 33 of the deflector and against at least part of the adjoining curved surface, the extent of the curved surface which is engaged being controlled by manipulating the entire device so as to alter the angle between the load, the deflector strip and the roll. This enables the degree of stretch applied to the web during a wrapping operation to be easily and rapidly changed and reduces the tendency of the web to "neck-in". <IMAGE>

Title: Apparatus for transporting cigarettes or the like between producing and consuming machines
IPC: A24C5/35
Filed: 1982-04-22
Abstract: Apparatus for transporting a multi-layer stream of cigarettes from a making or tipping machine to a packing machine has a set of conveyors defining an elongated path extending between the two machines, a tray filler adjacent to a first portion of the path to receive the surplus of cigarettes when the output of the making or tipping machine exceeds the requirements of the packing machine, and a magazine filler which delivers cigarettes to a second portion of the path downstream of the first portion when the requirements of the packing machine exceed the output of the making or tipping machine. The opening which allows the surplus of cigarettes to enter the tray filler can be closed when the requirements of the packing machine match or closely approximate the output of the making or tipping machine. Alternatively, such opening can admit a trickle of cigarettes into the tray filler even if the requirements of the packing machine match the output of the making or tipping machine; the magazine then admits a similar trickle of cigarettes into the second portion of the path. <IMAGE>

Title: Measuring temperatures and heat transfer coefficients
Inventor: WALLACE FRANK JULIUS
IPC: G01K17/00
Filed: 1982-09-15
Abstract: A probe is plugged into the wall of a combustion chamber, so that its distal end effectively forms part of the wall of that chamber. The probe contains two separate elongate bodies (3, 4) largely surrounded by an air gap and each containing two thermocouples (8, 9; 10, 11) one near the distal end and the other at the proximal end. The thermal conductivities of the two bodies are different and known, and the proximal end of the probe can be kept at a controlled temperature by cooling fluid from 7. From the thermocouple measurements and the known thermal conductivities can be calculated the heat fluxes in the two bodies, and hence the temperature in the enclosed space and/ or the heat transfer coefficient. <IMAGE>

Title: Improvements in and relating to automatic assembly process equipment
Inventor: ANDREWS ROBIN DESMOND RADCLIFF
IPC: B25J17/02
Filed: 1982-11-09
Abstract: A parts assembly gripper 2 for automatic assembly is mounted by suspension means 3 from a transfer apparatus 1, so that the spherical surface 7 at its remote end is in substantially vertical relation with the suspension 3, and automatically adjusts itself by gravity to maintain the alignment. In order to facilitate assembly of a transported item to its container 5, fixed guide tooling 4 is provided which has accurate alignment with the location of the container. During assembly, when the suspension means 3 is lowered, there may be misalignment with the container. The conical guide surface 9 cooperates with the spherical surface to align the item so that as the suspension means is lowered, the spherical surface enters the location bore 8, thereby ensuring close alignment with the container and permitting assembly. The suspension means possesses sufficient resilience to enable the gripper to align itself to the guide tooling as it is lowered during assembly. <IMAGE>

Title: An analog display electronic timepiece
Inventor: MORIYA TATSUO
IPC: G04C3/14
Filed: 1983-07-06
Abstract: An electronic analog display timepiece provides multifunctions wherein the hand, or hands, is driven at different frequencies. To prevent erroneous performance of the step motor, an interval longer than the period of damped oscillation of the step motor is provided when the step motor driving frequency changes by synchronizing the lower frequency driving signals with the signal of the highest frequency of the circuit. Alternatively, one pulse of the second frequency signal is eliminated when switching from the first to the second frequency signal.
