Abstract: 584,599. Adjusting wireless apparatus. HALL, H. S., and PYE, Ltd. Jan. 9, 1945, No. 702. [Class 40 (v)] In a tuning or similar control device having a flexibly mounted catch. engaging a stop disc mounted on a manually operated drive spindle which is coupled through a reduction gear to the driven device, a cam which rotates at the same speed as the driven device controls the catch to permit its engagement with the stop disc once only during the complete travel of the driven device. Thus the device can be rapidly and accurately re-set to a marked position. Bush 3 holds the controlled apparatus (not shown) and is carried by gear 4 meshing with pinion 5 on a manually-operated driving spindle 6. Pinion 10 is integral with stop disc 11 and meshes with gear 21, of similar size to the large gear of the driven bush 3. Stop disc 11 has'a notch 17 which engages with detent 19, the position of the latter being controlled by the action of cam 22 on arm 18. Cam 22 is mounted on the face of gear 21 and is contoured to provide one position in which the detent engages with notch 17. Stop disc 11 is free to rotate about driving spindle 6 but can be locked to it by balls 13 and taper-ended spindle 12. To set the apparatus, lever 14 is operated to release disc 11. A knob 24 is rotated to turn gear 20, cam 21 and disc 11 to cause arm 18 to engage notch 11.

Title: Improvements in and relating to fluid pressure braking apparatus
IPC: B60T15/54
Filed: 1919-01-13
Abstract: 141,422. Rendell, A. W. Jan. 13, 1919. Fluid-pressure.-In brake apparatus of the kind in which the train-pipe is vented into a closed chamber in making an application of the brakes, this chamber is exhausted to an extent dependent upon the pressure retained in the brake cylinder in effecting a partial release of the brakes, so that in making a further applieatiou of the brakes after such partial release the effective capacity of the chamber and consequently the extent of the application, is reduced. The apparatus shown comprises a triple valve 1 provided with a train-pipe venting chamber and operating in the manner described in Specification 24387/11. The brake cylinder exhaust passage 22 is controlled by a partial release valve 3 adapted to release the brake-cylinder air to an extent dependent upon the increase of the pressure in the train-pipe 2, which is connected to the valve 3 by the pipe 5. The valve 3 may be of the kind described in Specification 120,652. The train-pipe venting chamber is connected to a pipe 7 in the release position of the triple valve and interposed between this pipe and a pipe 23 leading to the pipe 22 is a valve 8 comprising an abutment 10 which by the action of a spring 25 is normally seated at 12 and through a spring 21 and plunger 24 holds a valve 17 in the closed position shown. When an application of the brakes is made, the triple valve connects the train-pipe to the venting chamber. Upon raising the train-pipe pressure in effecting a partial release of the brakes, the triple valve connects the venting chamber to the pipe 7, and the air therein unseats the valve 17 and abutment 10 and flows by the passage 15 and port 14 to the pipe 23, to which at this time the 'brake cylinder is connected by the triple valve and pipe 22. When the pressure in the venting chamber has nearly equalized with that in the brake cylinder, the spring 25 returns the abutment 10 and valve 17 to the closed position. The effective capacity of the venting chamber for a subsequent application of the brakes is thus adjusted according to the existing brake-cylinder pressure.

IPC: H04B10/00
Filed: 1987-01-05
Abstract: PURPOSE:To improve the operability and to reduce cost by switching an input electrical signal by a first switch circuit to input it, and switching an output electrical signal by a second switch circuit to output it. CONSTITUTION:In the titled transmitter which executes two-way multiplex transmission of optical signals using a single beam fiber, the switch circuits 30-11, 20-12 20-21, 30-22 are switched by using two pieces of optical transmitters 20-1, 20-2 of the same constitution and the single beam fiber 21. Accordingly, optical signals of wavelengths lambda1, lambda2 can be multiplex-transmitted in both directions, hence the optical transmitters 20-1, 20-2 have interchangeability with each other, and only one kind is required. As result, the operability can be improved and the cost can be reduced. Also, by containing the components of the transmitters 20-1, 22-2 respectively in one module, the respective transmitters 20-1, 20-2 can be miniaturized.

Title: Linear compressor and refrigerator using linear compressor
Inventor: SEKIYA SHIN
IPC: F25B1/02
Filed: 1997-01-07
Abstract: PROBLEM TO BE SOLVED: To reduce a radial displacement of a piston and to eliminate contact of a cylinder with the piston by axially disposing the piston between a pair of spring means. SOLUTION: Since a piston 9 is disposed at inside of a pair of spring means 11a, 11b, radial displacement of the piston 9 due to processing or assembling error of a leaf spring is reduced. In the case of axially displacing a movable element 21, a center 32b of the means 11b is radially displaced to 34b by δ1 and moved due to processing or assembling error of the leaf spring. Then, the element 21 is moved along a straight line 35. Here, since the piston 9 is disposed inside the means 11a, 11b, radial displacement δ2 of the piston center 9a becomes smaller than that δ1 of the center of the means 11b. Therefore, a gap between the piston 9 and the cylinder 10 is reduced, the piston 9 is not brought into contact with the cylinder 10.
