Patent GB-781244-A (GB)
Abstract: 781,244. Registering time of working of machines. HINLOOPEN, J. C. Jan. 27, 1956 [Jan. 29, 1955], No. 2774/56. Class 106 (4). Apparatus for registering the operative and inoperative periods of a machine comprises a pulse generator B co-operating with a changeover switch A controlled by the machine and a plurality of counters 30 to 35 co-operating with the pulse generator B and switch A to integrate the periods, classifying the causes and counting the number of stoppages. While the machine is operative it controls a movable arm 1 to contact a fixed contact 2 so that a disc 6 can repeatedly make and brake a circuit through a contact 5 to a counter 30 which registers the operative time. When the machine stops the arm 1 is moved on to contact 3, pulses to the counter 30 cease, an alarm 37 connected to the wiper arm 7 of a selector switch becomes operative through contact of the arm 7 with one of the interconnected contacts 19, 20, 21, 22, a counter 36 is advanced one unit and pulses created at contact 4 are counted on a signal time counter 35 so long as a wiper 8 coupled to the wiper 7 remains on the corresponding one of interconnected contacts 15, 16, 17, 18 of another selector switch. The alarm 37 warns an operator to adjust the selector switches so that the wiper arm 8 rests on that one of four independent contacts 11, 12, 13, 14 indicative of the cause of the stoppage, whereupon the alarm ceases and the pulses from the contact 4 are counted by the corresponding counter 31, 32, 33, 34 instead of by the counter 35. When the machine operates again the counter 30 begins to register pulses while all the other counters are inoperative. The alarm 37 also operates and the operator resets the wiper arms to their original positions.

Patent GB-789976-A (GB)
Abstract: 789,976. Igniting burners. MIDGLEY, A. H. April 21, 1955 [May 24, 1954], No. 15255/54. Class 75(3) In apparatus for automatically igniting a gas burner (not shown) on turning on the gas supply comprising a battery and inductance in series with make and break contacts 3. 6 close to the burner, one contact 6 is carried on a spring controlled movable member 5 connected to a second member, for instance the inner core 8 of a Bowden cable, actuated by movement of the gas tap beyond the open position to make the contacts 3, 6, the spring control effecting the turn of the gas tap to the open position and the breaking of the contacts 3, 6 so as to generate an ignition spark therebetween. The movable contact member 5 is pivoted to a bracket 4 and the fixed contact 3 is mounted on a plate 2 secured to but insulated from the bracket. A spring 7 holds the contacts apart. The outer cover 14 of the Bowden cable is anchored to the bracket 4. The other end of the inner core 8 of the Bowden cable is connected to a lever 11, Fig. 2, mounted for free pivotal movement on the gas tap spindle and actuated by a pin 12 on a disc 13 movable with the gas tap. The correspanding end of the outer cover of the: Bowden cable is secured to a fixed member 15 adjacent the gas tap. The pin 12 engages the lever 11 when the tap is turned to the open position and further movement beyond the open position causes the lever to pull the inner core of the Bowden cable and thus close the contacts 3. 6. On releasing the gas tap the spring 7 returns the tap to the open position and opens the contacts. In a modification the movable contact arm is mounted on a cup shaped member -slidably mounted on a cylindrical member, the cup-shaped member having two plungers' which slide in cylindrical recesses in the cylindrical member. A helical spring urges the cylindrical and cup shaped members apart to hold the contacts open. The inner core of the Bowden cable extends through one of the plungers and is attached to the movable contact arm, and the outer cover of the cable is secured to the cylindrical member. The ignition circuits of a number of burners may be arranged in parallel with a battery and inductance.

Title: Method and Composition for Producing Palladium Electrodeposition
IPC: C25D21/18
Filed: 1980-12-05
Abstract: A new aqueous electrolytic bath suitable for the electrodeposition of ductile, non-porous palladium coatings and a method for its use are disclosed. Prior palladium plating methods are slow and uneven in plating characteristics and do not produce pore-free coatings unless complex baths are used which cannot be readily regenerated. The prior art baths also produce environmental problems. The bath contains a palladosamine salt (chloride or bromide) as well as a dual electrolyte system composed of sulfamic acid and ammonium chloride. The method entails use of the bath under certain temperature and pH conditions. The new electrolytic bath is readily formulated and does not require the addition of additives. Significant amounts of ammonia and other undesirable fumes are not released from the bath during plating. Coatings produced from the bath are bright, highly adherent, ductile and generally pore- and stress-free. <IMAGE>
