Patent GB-2154829-A (GB)
Title: Improvements in telecine machines
Inventor: CHILDS IAN
IPC: H04N3/38
Filed: 1985-03-20
Abstract: Telecine apparatus preferably of the line array type has the line scan rate controlled in response to a tachometer sensing the instantaneous film speed to overcome problems caused by film speed variations. The output signal is compensated in inverse relation to the scan period to compensate for consequent variations in the integration time for the array. For very slow film speeds the actual scan rate is increased from the required scan rate by a factor of a power of two and unwanted scans (dummy scans) are ignored. For very fast film speeds the actual scan rate is decreased from the theoretically required scan rate by a factor m, likewise a power of two, and a full picture formed from lines from the latest m/2 fields, or by repeating or interpolating lines in the latest field only. To find a shot change at low film speeds the output picture has two parts, the junction between them being defined by a particular line scan, and the two parts being derived from two adjacent film frames. When the film is stopped, one part of the picture is the normal interlaced output and another part formed from a line direct from the linear array to enable proper functioning of the array to be confirmed. <IMAGE>

Patent GB-2211589-A (GB)
Title: Electromagnetic launcher
Inventor: MARTIN WILLIAM EUGENE
IPC: F41B6/00
Filed: 1987-10-24
Abstract: An electromagnetic launcher has a power supply 20 for supplying current pulses to five drive coils 21-25, each having its own pulsed current supply 27-31 and associated capacitor C1-C5 and magnetic switch S1-S5, the switches becoming conductive when the associated capacitor is substantially fully charged. As the projectile approaches, current is caused to flow in its coil 32 thus establishing a magnetic field which increasingly threads the drive coil 21. The current from supply 27 and that induced by the approach of the projectile are sufficient to open the switch S1, a large pulse of current from the capacitor C1 then being supplied to the drive coil 21 to accelerate the projectile. The remaining drive coils 22-25 and associated components operate in the same manner. In another embodiment (Fig 3), the power supply is in the form of a magnetic pulse compression line (42), and each drive coil (43, 44) of the launcher is coupled to a current loop of that line. In yet another embodiment (Fig 4), a transmission line (56) including saturable magnetic material forms the single drive member of the launcher. <IMAGE>

Abstract: 875,001. Methods of fixing a free-standing fire in a fireplace. NEWTON, CHAMBERS & CO. Ltd. Feb. 6, 1959, No. 4344/59. Class 126. [Also in Group XXVIII] A method of fixing a free-standing solid fuel fire 1, Fig. 6, in position in an existing fireplace with its flue outlet 25 sealed to the chimney flue 5 through a tube 10 comprises fixing the tube in position while it is in contact with an inclined surface of a vertical template standing in the hearth, the inclined surface being at the same inclination and height as the surface of a flange 23 of the flue outlet of the fire when this is in position and thereafter the fire is put in position and fixed to the tube. The tube forms part of a unit 9, Fig. 3, the tube having an integral flange 12, and flexible metal mesh skirt 13 which is manually bent to fit into the flue 5 when held in position by the template. The unit is then removed and a flexible sheet of asbestos millboard 14 with a central opening which the tube can enter is put on the mesh around the tube, and the lower side of the unit is covered with cement 15. The unit is fitted skirt-first into the flue 5, the template reinserted, the skirt and asbestos manually distorted to conform to the walls of the flue and additional cement 36 is applied to seal the unit in the flue. The fire is then fitted into the fireplace with lugs 28 on the flange 23 of the outlet 25 registering with lugs 19 on the flange 12, which lugs are secured in position by screws 18 which receive wing nuts 16 and the joint is sealed by asbestos rope 26. The fire is further secured in the fireplace by a stake 30 which in its inoperative position is held against the rear face of the fire by a screw 33 and wing nut 35 and when the fire is in position it is released to drop into a hole in the hearth which has been previously located by a mark on the template. Specification 797,229 is referred to.

Abstract: Detachable lids for use with disposable drinking cups which enable the user to drink with the lid in position, comprise a rim (2) adapted to form a substantially fluid tight seal with the inner or outer edge of the open end of the cup and a circular central cover portion (1) formed from resilient sheet material. The cover portion (1) has a surface area greater than the area it covers and two arcuately hinged rim portions (5, 6) on opposite sides so that the cover portion has two substantially stable positions. In the first position the cover portion lies substantially below the plane of the rim and in the second position the cover portion lies substantially above the plane (see Figure 4). As a result in the first position the lid substantially seals the cup and in the second position two substantially diametrically opposed apertures are formed between the rim and the edge of the cover portion to act as an air entry aperture and a fluid exit aperture respectively. The lid preferably has a tab (12) on the upper surface of the central section of the cover portion. This assists the user to change the cover portion from one to the other of its stable positions. <IMAGE>
