Abstract: 637,007. Hand actuating devices for switches; locking switches. WILLIAMS, H. M. April 20, 1948, No. 10832. [Class 38 (v)] A link 4 connecting together switch handles 3, 3a is formed with a slot 7 and a handle-receiving bore 6 in which the handle 3 is secured by a bolt 5, the slot permitting the handle 3a to be moved in one direction by the link but not in the other, provision being made at holes 9 in the slot for a bolt 8 to effect the control of the handle 3a so that both handles can be moved in unison if desired. The slot 7 may be extended in the link and a hole 9a provided therein so that the handles 3, 3a may be locked facing opposite directions. In another embodiment, Fig. 9, the handles are rectangular in crosssection, and are drilled to receive a split-pin 5a or the movable bolt 8. To prevent the handle 3 leaving the slot the link is drilled at 9c, 9d and one of the bolts' 8 passed through these holes and the hole 9b in the handle. The slot may be also extended and an additional hole 14 provided so that the handles may be locked with one switch " on," the other " off." A further modification, Fig. 12, comprises two bars 4 bent to suit the switch handles and spaced apart by spacers. To prevent the link parting from the handles the bars 4 may be provided with chamfered sides 7a at the slots 7 or the handles may be drilled to receive a crossbar, Fig. 11 (not shown) or a bolt 8, or the bars may be shaped to embrace the knob 3c on the handle, Figs. 13, 14, 15 (not shown). The bars may be provided with a support, Fig. 13 (not shown) which holds the link clear of the switch face-plate. The bars 4 may have holes 22 which can be aligned with a staple 21 secured to the face-plate so that the switches can be locked. Springs 18 may be secured to the link to cause it to return the switches to the initial position when the operator's finger is removed. A solid link slotted to suit the number of switch handles controlled thereby may be used also (Figs. 16, 17, not shown).

Patent GB-559891-A (GB)
Title: Improvements in or relating to master cylinders for hydraulic transmission systems
IPC: B60T11/22
Filed: 1942-08-06
Abstract: 559,891. Telemotors. HYDRAULIC BRAKE CO. Aug. 6, 1942, No. 10995. Convention date, Oct. 13, 1941. [Class 69 (ii)] [Also in Group XXXIV] In hydraulic master cylinders for operating brakes and for other purposes, the piston is formed as a reservoir for supplying the system and contains open means for maintaining a light pressure normally in the system. Also the cylinder is provided with a chamber in which air that may accumulate in the system may collect and from which it may be allowed to escape. The master cylinder 12 connected at 36 to the pipe system contains a hollow piston comprising a tubular part 50, a head 56 upon which is seated the sealing cup 68, and a plug 72 screwed into the other end of the part 50. The cylinder is closed by a flexible boot 86 secured to an end collar 54 and to the operating rod 80 of the piston which is provided also with a sealing washer 74. The piston chamber 60 contains liquid and normally communicates with the forward part of the cylinder through a port 62 in the piston, ports 14, 16 in the cylinder and a chamber 20 formed by a member 22 fixed to the cylinder. The liquid in the chamber 60 and thus normally in the system is maintained under pressure by a piston 100 slidable in the main piston and loaded by a spring 108. When the main piston is returned by the spring 70 after an operation the tendency of the pressure in the cylinder chamber to fall causes liquid to flow from piston chamber 60 to the cylinder through passages 66 in the piston and past the cup 68. The liquid that subsequently returns from the pipe system under the action of the brake release springs, returns to the piston chamber 60 through the ports 16, 14 and chamber 20, re-compressing the spring 108. Air in the system collects upon and passes through a perforated screen 32 disposed in the chamber 20 and is permitted to escape by opening a bleeder valve 30 that normally closes this chamber.

Title: Improvements in or relating to electric gas-discharge lamps
IPC: C09K11/02
Filed: 1938-04-11
Abstract: 495,549. Discharge lamps. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. April 11, 1938, No. 11113. Convention date, April 13, 1937. Drawings to Specification. [Class 39 (i)] [Also in Groups XI and XX] The ultra-violet rays from a discharge lamp the majority of which are below 3300 Š, are caused to strike first a luminescent powder layer which absorbs 30 to 70 per cent of the rays to which it is responsive, and then fall upon a luminescent glass layer which responds to the same rays. The powder layer may be made thin while at the same time absorption losses in the luminescent glass are reduced. A lamp with a filling of mercury and neonargon mixture at 10 mms. pressure has an envelope of copper-activated luminescent glass, coated internally with a layer of willemite which absorbs 60 per cent of radiation below 3300 Š. Magnesium vapour may be used. Alternatively, the luminescent powder may be coated on the outside of the lamp, while the luminescent glass forms a further envelope surrounding the lamp. Specification 473,587 is referred to.

Title: Improvements relating to light electric cells
IPC: H01J40/04
Filed: 1929-04-10
Abstract: 311,701. Rother, F. May 14, 1928, [Convention date]. Vacuum tubes. - The cathode or anode, or both, or an auxiliary electrode consists of cold radioactive material such as chromium or thorium alloy, whose alpha particles penetrate the surface of the light-sensitive cathode. As shown, the cathode 2 consists of a coating of potassium on the glass envelope, and a grid-shaped anode 3 consists of thorium &c. Alpha rays emanating from the anode increase the electron emission from the cathode. The gas 'pressure should be such that ionization by alpha rays is insufficient to produce a current unless the cathode is illuminated. In a modified cell which is sensitive to a certain wave length, both the anode and cathode are of radioactive material. In another arrangement an auxiliary electrode, disconnected from the circuit, is formed of radioactive material.

Title: Vehicle door fastenings
Inventor: KORNER REGINALD JOHN
IPC: E05B65/32
Filed: 1959-04-02
Abstract: 870,654. Vehicle door fastenings. MORRIS MOTORS Ltd. Nov. 6, 1959 [April 2, 1959], No. 11167/59. Class 44. A vehicle door latching mechanism comprises a U-shaped striker 2, Fig. 1, having a latch engaging abutment 1 adapted to be secured on the door post and a plate 15 carrying on a radial arm 9 a striker engaging roller 10 adapted for fixing to the door edge 5. The arm 9, which is formed with a safety catch 12, is rigidly mounted with a spring-loaded doubleended lever 13, Fig. 2, the upper end of which may be swung inwardly to move the roller 10 from the abutment 1 by a plunger 16 on actuation of a press-button 17 located on the external door panel 6. The lever may also be actuated to disengage the roller from the abutment by rotation of a cam surface 20, Fig. 3, which is mounted on the plate 15 and is rotatable by the movement of chain or line 21 operable from within the vehicle. This movement may be prevented as a safety measure by the locking of the cam through the engagement of a member 28, mounted thereon, and a catch 29 pivotally mounted on the door edge 5. Locking of the latching mechanism from within the vehicle is effected by depressing a rod 23 which, through an arm 24, removes the plunger 16 from any possible contact with the lever 13. Should the door be slammed in "door locked" position movement of the arm 9, as the roller runs up the striker preparatory to dropping behind the abutment 1, rotates the lever 13 such that a rod 25 connected thereto moves upwardly to actuate the arm 24 and thus the rod 23 to establish the unlocked condition. Upon closing the door, a projection 7, Fig. 4, on a locating member 4 mounted on the door edge 5 enters a recess 8 in the striker 2, this interengagement preventing dislodgement of door and door post should the vehicle crash.

Title: Improvements in or relating to electric power transmission mechanism especially applicable to the propulsion of motor vehicles
IPC: H02P9/06
Filed: 1924-05-12
Abstract: 238,016. Gillett, E. H. J. C. May 12, 1924. Dynamos and motors combined for transmitting power; electromechanical power-transmission systems.-An electric power transmission system applicable to motor road vehicles comprises a series-wound clutch generator, the field a, Fig. 4, of whch rotates with the prime-mover and the armature b of which is fast on the driven shaft A. The slip current generated by the machine a, b is supplied to a series motor of which the field c is fixed and the armature d is connected to the driven shaft A through reduction gearing and a free-wheel device contained in a casing E. The armature c is fast on a sleeve B, Fig. 1, rotatable on the shaft A, and a gear G on the sleeve B meshes with planet pinions F which also mesh with a fixed internally toothed gear E<1>. The pinions F are rot.atably carried by a part H, which drives, through an overrunning free wheel device of the spring- pressed roller type having rollers K, a part J splined on the shaft A. During reverse drive, the part J is moved axially by a lever engaging a groove J<4> so as to connect the parts H, J by means of a dog clutch, thus rendering the freewheel device inoperative. The electrical connections of the two machines a, b and c, d are shown for each running position of a controller. Fig. 5 shows the first speed position in which a storage battery j in series with a. resistance e secures a steady excitation of the field a which is shunted by a resistance f. In the second speed position the resistance f is replaced by one of larger value, and in the third the shunt and battery are disconnected. In the fourth and fifth positions the field c is shunted by a resistance of decreasing magnitude, and the armature is also provided with a shunt field in series with a resistance. In the top-speed position, both machines are electrically separate and short-circuited upon themselves, thereby holding the armatures stationary relatively to the fields. For reverse drive, the field of the machine c, d is reversed, and owing to the reduction gear it imposes a reverse torque on the shaft A greater than the forward torque imposed by the machine a, b. The circuit shown in Fig. 13 is used as a brake or for restarting the engine while the vehicle is running, both machines are short-circuited through resistances and have their fields reversed. In a modification of the circuit shown in Fig. 13 the resistance in circuit with the machine c, d is reduced and both sides of the armatures b, d are connected together. The primemover can be started in the usual way by using the machine a, b as a series motor supplied by the battery, which can be charged when the vehicle is at rest by using the machine a, b as a shunt-wound generator, or when the vehicle is moving by a separate small generator mechanically secured to the machine a, b.
