Title: Improvements in and relating to devices for Protecting the Output Stage of a Radio-Electric Transmitter
IPC: H03F1/52
Filed: 1966-08-23
Abstract: 1,150,584. Monitoring radio transmitters; keying oscillators. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 23 Aug., 1966 [26 Aug., 1965], No. 37643/66. Headings H3T and H4L. In an arrangement for protecting the output stage of a radio transmitter the output stage T 5 , 12 feeds the aerial via a directional coupler 13 which includes a detector circuit supplying a direct voltage to the base of a transistor T 1  in the protecting device 18 when a reflected wave occurs in the coupler 13 due to abnormal operation. The transistor T 1  normally is conducting but when a voltage is supplied from 13 it is cut off and drives transistor T 2  into saturation to short-circuit a Zener diode Z. Under normal conditions the diode Z counteracts small supply voltage fluctuations but when it is shortcircuited the drop of potential at the base of the master oscillator transistor T 4  causes this transistor to be cut off to remove the drive from the output stage. A meter 15 is provided to indicate correct tuning of the aerial circuit.

Title: Improvements in grabs
IPC: B66C3/08
Filed: 1928-12-21
Abstract: 323,359. Page, M. W. Flood-, and Westwood & Co., Ltd., J. Dec. 21, 1928. Grab-buckets.-Relates to grabs comprising a main frame 1 with buckets pivoted thereto at 6 and connected with a sheave-block 3 by locking-mechanism which is released by a triggerlever 24 engaging over a suspended ring 25, the locking-mechanism being re-engaged when the buckets rest upon the ground, as shown in Fig. 6, with the locking device below the frame 1. To reduce the overall height, when the block 3 is lowered in the guides 2, the trigger-lever 24 is turned into an approximately vertical position, so that it may pass below the upper lever of the frame 1. As shown, the locking device comprises a sleeve 9, Fig. 3, carried by the block 3, engaging over a vertical pin 10 and provided with a horizontal pin 11 which may be turned on its axis for locking and unlocking the sleeve 9 on the pin 10. The pin 10 is mounted on a block 14 connected with the buckets by links 15, and is kept vertical by a tail-rod 17 sliding in a block 18 connected with the buckets by links 19. The buckets are also steadied by outside links 20 connected with a slide 21 moving in the guides 2 at one side of the grab. The pin 11 is provided with a weighted arm 30 having a contact surface 31 engaged by a counterweighted lever 22 loose on the pin. This lever is connected by a link 23 with the trigger-lever 24 which is also carried by the block 3. An extension 26 of the, lever 24 forms a counterweight and is provided with a bearing surface 27. When the block 3 is lowered in the guides 2, the surface 27 meets an abutment 28 on the guides and the trigger lever 24 is turned downwards so as to pass the frame 1. With the open buckets resting upon the ground, the block 3 is lowered to bring the sleeve 9 over the vertical pin 10 and the horizontal pin 11 is turned automatically into the locking position by the weighted lever 30. When the block 3 is raised the buckets are closed as shown in Fig. 1, and if the trigger-lever is raised through the ring 25 and the grab is then lowered, the levers 24 and 22 are raised and the lever 22 engages the part 31 to lift the lever 30 and release the pin 10 allowing the buckets to open. To permit opening of the grab by lowering it on to the ground, the counterweights 26, 32 on the, levers 24, 22 may be made to overbalance the weighted lever 30. The pin 11 will then be released as soon as the weight of the buckets is supported on the ground leaving the pin free to turn, and the parts will be re-engaged automatically as described above, since in the position shown in Fig. 6, lever 22 is held away from the part 31. The opening of the buckets when suspended in mid-air is cushioned by a dash-pot 7.

Title: Clothes washer machine
IPC: D06F58/08
Filed: 1961-10-27
Abstract: 915,244. Change-speed gear and control. GENERAL MOTORS CORPORATION. Oct. 27, 1961 [Nov. 18, 1960], No. 38521/61. Class 80 (2). [Also in Groups VIII and XIII] A washing-machine drum is rotatable about a non-vertical axis by a motor 84 through a trans. mission including a spring clutch 180 and a device for preventing engagement of the clutch by any reverse rotation of the drum such as may occur due to unbalance of the clothes when the drum comes to rest after rotation. This device comprises a solenoid operated pin 186 biased by a spring 200 into engagement with one of several notches 198 in a plate 166 to which one end 182 of the spring 180 is secured. When the plate 166 is held by the pin 186 against rotation, the spring 180 tends to unwind and low-speed rotation is transmitted through a pinion 116 on the motor shaft 112, a gear 146 meshing with the pinion 116, a spring clutch 174, and a gear hub 152 keyed to a shaft 130 carrying a pulley 140 connected by belt drive to the clothes drum. When the solenoid 188 is energized pin 186 is withdrawn and high-speed drive is transmitted to the drum through a clutch hub 160 keyed to shaft 112, clutch spring 180, a gear hub 158, gears 156, 150 and shaft 130. After a spindrying period, a timer de-energizes the motor 84 and solenoid 188, and the plate 166 is arrested by the pin 186 before the clothes drum comes to rest. Any reverse rotation of the drum is therefore prevented by the pin 186 from causing reverse rotation of plate 166 which would tighten the spring 180; subsequent clothes tumbling starts at low speed. Energizing of solenoid 188 to withdraw pin 186 (for spinning) does not take place until the drum has rotated for a period at low speed.
