IPC: B60J7/12
Filed: 1950-01-30
Abstract: 675,610. Securing folding hoods. WILMOT-BREEDEN, Ltd., and BURGESS, W. H. Jan. 29, 1951 [Jan. 30, 1950], No. 2331/50. Class 108(i) [Also in Group XXV] The main pillar f of a collapsable hood pivoted at g, Fig. 1, is connected at each side of the vehicle through plates d and piston-rods c to hydraulic cylinders b, each of which cylinders is pivotally mounted in a slot h and is connected by a link or cable j to a spring-loaded slidable catch k adapted to secure the hood in its extended position as shown. When pressure liquid is supplied to the cylinder the latter moves downwardly in the slot relative to the rod c, thus unlocking the catch k and permitting the continued action of the pressure to collapse the hood. In the modification shown in Fig. 3, the pivoted cylinder does not move relatively to its piston-rod, but when pressure liquid is supplied to the cylinder a lever p, also pivoted at g, is first moved between the stops o to unlock the catch k, continued movement then collapsing the hood. An electric motor may be used instead of hydraulic means.

[Class 97 (i).] Anamorphotic systems. -All optical soundrecording apparatus comprises two cylindrical lens systems which are respectively adapted to focus the recording area of light to the required dimensions in one direction and in another direction perpendicular to the first. One of the lens systems comprises two lenses A, B, the lens A causing the light from a source L (which in the arrangement shown is an electric lamp filament, partially masked by a plate E) to form a parallel-sided beam, while the lens B concentrates the light to a focus on the film. The other lens system, which is a single, cylindrical lens C of very short focal length, having its axis at right angles to the axes of the lenses A, B, serves to reduce the strip of light formed by the double lens system to a fine intensely bright line on the film S. With this arrangement, independent focusing by the two lens systems may be effected, so that either the breadth or the length of the luminous image may be readily adjusted. A convenient manner in which a mirror M, vibrating in accordance with the sound to be recorded, may be arranged in conjunction with the optical systems, is shown in Figs. 4 and 5. A further cylindrical lens X is in this case provided to concentrate the light beam in the appropriate dimension upon the mirror. The lens X may be omitted, but all the available light in the beam would then not be utilized. A simple magnifying or reducing lens may be additionally provided if required.

Title: Improvements in or relating to tape dispensers
IPC: B65B51/06
Filed: 1959-01-23
Abstract: 913,221. Electric correspondence-control systems. BETTER PACKAGES Inc. Jan. 23, 1959 [Jan. 29, 1958], No. 2605/59. Class 40 (1). [Also in Groups XVII and XIX] In a tape-dispensing device the amount of tape required to seal a box is controlled by a number of contact switches operated by the box itself, thus ensuring that the length of tape dispensed is dependent upon the length and breadth of the box. The box is placed on a table 5 and engages contacts 19, 21 and also a trip lever 33 which cause the tape feed to commence. When the length of the box is measured the contacts 19 are in circuit and contacts 21 are disconnected; when the breadth is measured contacts 21 are in circuit and contacts 19 are disconnected. Members 19, 21 are associated with resistors 27, 29 connected in series so that the dimensions of the box control the resistance of a circuit and thereby the time required for a capacitor 218 to be charged and a thyratron 217 to fire. After firing, the tape is cut by a solenoid-operated cutter. Variable resistances 176, 178 are provided to enable adjustment to be made to the time required for the capacitor to become charged. Pushbuttons enable the tape to be dispensed in the absence of a box, and means is provided to prevent one cycle of operations commencing before the previous cycle has been completed. In a second embodiment, engagement of a box with members 19 or 21 energizes a stepping relay and each rotation of the tape feed wheel causes the relay to move one step until a contact which has not been energized is reached. In a third embodiment (Fig. 29), the feed-wheel moves an arm 804, carrying switches 806, 808. When a box is placed on the table 5 a solenoid 810 operates the switch 806 and the arm moves past solenoids 800 energized by the contacts 19, 21, until the switch 808 is operated by a solenoid that has not been energized, the tape is then stopped and cut. Specifications 643,731 and 827,188 are referred to.

Washing-machines with swinging rubbers in stationary receptacles; wringers, driving-gear for.-A slipcoupling, is provided to permit overrunning under excessive load. A mechanism for driving both a washer and a wringer, or either, comprises a beltdriven shaft 3 carrying a loose pinion 5 meshing with a spur-wheel 6 loose on a shaft 7. The washer is operated from this shaft 7 when a clutch 14 pinned to the shaft engages with the boss of the spur-wheel 6. To stop the drive, the clutch is withdrawn by means of a crank 17 provided with projections 18 adapted to ride out of recesses in the fixed boss 19. The wringer is driven by bevel-wheels from a fast spur-wheel 9 meshing with the wheel 6 and connected and disconnected with one of these bevel-wheels 12 by means of the spring-controlled sliding spindle 10 and a crank 20. The pinion 5, provided with recesses 27 in its boss, is urged by a spring 28 into driving engagement with a pin 26 on its shaft. If the load is excessive, the pin forces the pinion back, and so allows spring-controlled catch-levers 29 to engage shoulders on a disk 5a attached to the pinion. The pinion is thus maintained inoperative until released by manual actuation of the levers.
