Title: Improvements in or relating to Controlling Mechanism for Mechanically-propelled Rail Vehicles.
IPC: B60K28/00
Filed: 1917-11-27
Abstract: 120,130. Daimler Co., Balcombe, H. J., and Dawson, T. Nov. 27, 1917. Controlling different functions by same handle or lever; stop-gear operated by driver releasing a lever.-A motor rail vehicle propelled by an internal-combustion engine is provided with control mechanism operated by a single lever fitted with an emergency device for automatically applying the brake and stopping the engine, if it is in gear, in the event of the driver releasing the lever. The hand-lever passes through a slotted gate quadrant 15 and is mounted on a shaft 22 by means of a pin 20 and trunnion 21 so as to be movable in the slots of the quadrant. From the neutral position, shown in Fig. 1, the lever can be moved to the right into the slot 16 so as to engage with the lower lever 25, and when moved to one end of the slot brings the engine into action through the gears, and when moved to the other end of the slot causes the engine to drive direct. Similarly, when the lever is moved to the left into the slot 17, the brake lever 24 is engaged and the brake can be manipulated as required. The emergency device consists of a trigger 3, Fig. 2, connected to a spring-pressed rod 4 adapted, when the trigger is released, to engage a sliding block 6 pressed upwards by a spring 7 which is weaker than the trigger spring. If the trigger is released while the hand-lever is in neutral position, the sliding block 6 is pressed downwards to the position shown in Fig. 1, and a contact 8 carried by the block 6 engages with a relatively fixed contact 10 carried by the hand-lever and completes an electric circuit through a solenoid 13 which opens a valve 14 in the pneumatic brake system and applies the brakes. If the trigger is released when the hand-lever is in one of the slots, the conical stop on the trunnion 21 allows the contact 8 to engage with the contact 10 and apply the brake as before and also to engage with a contact 11 in the magneto &c. circuit and so short circuit it and stop the engine. If the vehicle has more than one engine, a corresponding number of stops 11 may be provided.

Patent GB-1308035-A (GB)
Title: Automatic control systems
IPC: H01H43/16
Filed: 1970-04-15
Abstract: 1308035 Counting apparatus RICOH KK 15 April 1970 [25 April 1969] 17862/70 Heading G4D When it is desired to cause a machine e.g. a photocopier, (not shown) to perform a number of cycles, shaft 25 is displaced from its normal position by knob 2 into the appropriate one of a plurality of discrete angular positions from which it is returned to the normal position in discrete steps by means of a ratchet 29 on the shaft, the arrangement being such that the number of steps required to return the shaft 25 to its normal position in which it causes closure of switch 22 is one less than the number of cycles that it is desired that the machine will perform. The closure of switch 22 enables the machine to perform one further cycle whereupon its internal control circuit automatically opens to stop the machine. An arm 3a of a lever 3 biased clockwise by a spring 31 is arranged to be depressed by a coupling member of the machine at the end of each cycle. Such depression causes a lever 30 co-pivotal with lever 3 to follow the anticlockwise movement of lever 3 through the coupling spring 32 which biases an arm 30a of lever 30 into engagement with an arm 3b of lever 3. A pawl 33 biased anticlockwise by spring 35 is thus permitted to step ratchet wheel 29 one step anticlockwise as a pin 33b of lever 30 disengages a surface 33b of pawl 33 and engages a surface 33c. Subsequently pawl 33 disengages ratchet wheel 29 and returns to the position shown. Anticlockwise movement of lever 30 also causes an arm 30c thereof to rotate a catch 38 against spring bias so that cam follower 24 drops from ledge 38a to ledge 38b thereby allowing switch 22 to open and prevent the control circuit of the machine from opening so that the next cycle is automatically initiated. The cam follower 24 remains in this position until the ratchet wheel 29 is returned to its normal position in which a non-toothed part 29a of the wheel 29 is below the pawl 33. In this position a pin 26 carried by an index wheel 27 of the shaft 25 raises the cam follower 24 to close switch 22 so that the control circuit of the machine automatically opens at the end of one further cycle. The catch 38 is returned to its initial position when the cam follower 24 is raised by pin 26. Switch 22 has a plug for connection to the machine.

[Also in Group XL (a)] A crystalline phosphor is coupled optically to a sheet of glass or glass substitute by a transparent substance having substantially permanent cold flow characteristics and refractive index between 1.403 and that of the glass or glass substitute, the substance being retained by sealing material. High viscosity silicone fluid 4 couples the crystal 5 and the glass or silica glass window 1, an aluminium mounting ring 3 enclosing them and being held in position by resin cement 6. The glass window 1 is retained on a can 7 by a ring 8 and cement 9, 10. The phosphor may be a single crystal of an alkali halide actuated by a heavy metal, e.g. thallium or tin, coated with light reflecting material, e.g. T1-2. The interior of the can may be silvered and vacant space filled with powdered Mg 2 . There may be a window in the can for admitting ultraviolet or other less-penetrating radiation. Fig. 5 shows a modification for radiation of low penetrating power, a metal foil 17, e.g. of polished aluminium, being placed in direct contact with the crystal the whole cemented in a cylinder 7. The crystal may be held in position by a neoprene ring fitting in an annular groove in the enclosing ring, Fig. 6 (not shown). The phosphor may be organic, and a powdered phosphor with binder may replace the single crystal.
