Patent GB-262129-A (GB)
Abstract: 262,129. Delpech, F. P. A. E. Nov. 27, 1925, [Convention date]. Factory and like time-recorders, cardtype. - In apparatus of the individual card type a record of the time of arrival and departure is made on a number of record cards simultaneously by inserting the cards in a holder and then releasing it so that it is moved into contact with a perforating punch movable along a given path under the control of a clockwork mechanism. The clockwork mechanism and the punch are mounted on a longitudinally movable frame plate so as to position the punch according to the day of the week. The card is printed as shown in Fig. 4 and is punched with holes 12 to ensure the correct positioning of the card in the holder. The card holder g, Fig. 1 is mounted on a spindle h provided with a handle j normally held in the vertical position by a catch lever under the control of a knob k. When the knob is depressed by the employee the card-holder falls under the action of gravity and a punch 15 perforates the cards to record the time of operation. The punch is mounted on a slider 3 guided in a slot 2 of a cover plate c superimposed on the clock mechanism a. The clock driven a heart shaped cam 4 formed with a groove 17 in which works a ball carried bv the slider 3 so that the slider is moved proportionally to the time. A plate 25 on which the clock is mounted is movable in guides 26 so as to position the punch according to the day of the week. To avoid the necessity of turning the card over every six hours to obtain a record in the normal order of the hours due to the to-and-fro movement of the punch the spindle of the clock is adapted to rotate once in twenty-four hours and the punch is adapted to travel the length of the card by the means shown in Fig. 3. The slider 3 carries a pulley 27 around which passes, in opposite directions, two cords 28, 29 attached respectively to the opposite sides of a frame and of the punch 15 which is itself guided on wires or rods 37. The card holder is constituted by two plates held apart by springs surrounding pins on one of said plates. When the card holder is allowed to fall the plates move together and plungers on tile inside of the plate enter the holes 12 in the card to hold it in position.

Title: Improvements in or relating to brake mechanism for road tractors
IPC: B60T7/20
Filed: 1935-09-23
Abstract: 463,249. Vehicle brakes. TAPP, E. T. J. Sept. 23, 1935, No. 26313. [Class 103 (i)] The brakes of a tractor and a trailer vehicle are operated by a common pedal &c. and the transmission for the trailer passes through the coupling the arrangement being such that the proportion of braking power between the two vehicles is varied by fore-and-aft movement of the trailer relatively to the tractor, the trailer brake application being accentuated and decreased respectively by overrun and separation of the trailer relatively to the tractor and the' tractor brake application being correspondingly decreased and increased. A swiveltree d pivoted at f on a plunger e is connected by links h, i to arms on cross-shafts c, c<1> operated by pedal b and hand-lever a respectively. The plunger e is connected by cable j to a push rod k slidable in the tractor portion of the coupling and engaging a lever l on the trailer connected by rod n to the trailer brakes. Rods p, q are connected to the tractor brakes. The brakes may thus first be applied lightly by the hand lever, and the application be completed by the pedal. In order that the pedal stroke may be sufficient to apply the brakes completely by the pedal alone, the swivel-tree may have a stop g to prevent its movement in such an application and thus transmit the pedal movement without reduction. The plunger e may be connected to the swivel-tree at a point nearer to the hand connection than to the pedal connection. When the trailer brake has been manually applied, relative movement between the trailer and tractor turns the lever l due to its abutment on the rod k and thus effects a variation of the trailer brake pressure and an inverse variation of the tractor brake pressure. The extent of this action is determined by screw adjustment of the rod n and the adjustment may be such that the tractor brakes may be applied lightly and the trailer brake be applied only by overrun of the trailer. The coupling may be such as described in Specification 463,247 the push-rod k being mounted in the cross-head of that coupling and make contact with a lever pivoted on the forked draw-bar when the cross-head is embraced by the claws.

Title: Improvements relating to processes for decomposing lignin
IPC: C08H5/02
Filed: 1954-09-10
Abstract: Distillable phenolic products are formed by the decomposition of lignin by a continuous treatment with hydrogen at above 350 DEG  C. and at above 350 atmospheres pressure.  A thin paste or sludge of lignin and a high-boiling liquid, such as xylenol or the products of suitable boiling range from a previous lignin decomposition, is continuously passed with hydrogen through a reaction chamber at the reaction temperature and pressure, the reaction mixture being cooled immediately after leaving the chamber.  The hydrogen is separated and recycled and the liquid products are distilled to give an oil-containing phenols.  The process may be effected using lignin from wood-saccharification processes such as the Scholler process or from waste liquors from the sulphate process for cellulose, any sulphuric acid present being neutralized with lime. In examples: (1) lignin from the Scholler process with quicklime and xylenol in the form of a thin paste is heated with hydrogen under 700 atmospheres pressure and at 380 DEG  C., the reaction time being 1 1/4 hours, the liquid product is distilled after removal of calcium sulphate by filtration to give an oil containing phenols, and the hydrogen is recycled; (2) and (3) illustrate the same process using (2) a shorter reaction time, and (3) a lower pressure.  Specification 542,471, is referred to.

Title: System for transmission of analogue data over a single trans mission channel from one of a plurality of remote stations to  a central station
IPC: H04Q9/00
Filed: 1973-06-01
Abstract: 1431951 Selective signalling PHYSICS INTERNATIONAL CO 1 June 1973 26334/73 Heading G4H In a system for transmission of analog data over a single transmission channel from sensors at one of a plurality of remote stations to a central station, the central station sends an address signal to select one of the remote stations and initiate therein a ramp signal and transmission of a plurality of distinct tones associated one with each sensor, transmission of each tone being terminated when the ramp equals the output of the respective sensor. The address signal is one (or more) tone and recognition of it in a remote station triggers a pulse generator, the pulse from which is integrated to constitute the ramp, the leading edge of the pulse also closing switches passing the outputs of sensor tone generators, each switch being subsequently opened under control of the respective comparator comparing the respective sensor output with the ramp. The durationsignificant tone outputs are sent together over the transmission channel (e.g. telephone line) to the central station, followed by the remote station address tone(s). Each duration-significant sensor tone is passed by a filter respective to its frequency, amplified, rectified, filtered (using a capacitor), amplified and integrated to reproduce the original sensor output amplitude which is stored on a respective capacitor. The address tone sent out from the central station is also filtered &c. in the central station to trigger a monostable to define a time interval during which the remote station should send its address tone back (as mentioned above). If it arrives during this interval, an AND gate, responsive to the monostable and to a filter &c. recognizing the returned tone, actuates a relay to pass the capacitor outputs via a sequencing switch to remote indicating, recording and processing stations.
