Abstract: 317,061. Schwabedissen, K. Aug. 9, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Books with tear-out portions; carbon papers, arrangements of. - The sheets comprising a set of manifolding-sheets are of different colours, each sheet having its rear face coated with copying material of its own distinctive colour, so that when separated they are readily identified and assigned to their different uses. Any number of differently coloured sheets may constitute a set and are preferably fastened together by a clip or other means during the typing or writing of entries. Several sets may be assembled into a pack, with a projecting tab or signal between each set, and bound together by stitches adjacent to a line of perforations which facilitate the detachment of the sheets. Alternatively the sheets may be stuck together along one edge from which they are readily torn, and tearing-threads may be provided to render the tearing easier. In another form, Fig. 2, a number of differently coloured webs of paper are wound into a roll 9 upon a common spindle 10 from which they can be unrolled and inserted into a typewriter, transverse perforations B being provided in each web to enable the sets of sheets to be separated when filled in. A second line of perforations 8<1> is preferably provided and the space between the two lines of perforations coated with adhesive to secure the superposed sheets of each set together and retain their alignment. Instead of colouring the entire surface of each sheet parts only may be coloured or provided with other distinguishing marks.

Title: Method of and apparatus for the production of carbon dollies for galvanic cells
IPC: H01M4/10
Filed: 1929-08-14
Abstract: 332,101. Bumke Ges., H. A., and Autom Spezial-Maschinen Ges. July 26, 1929, [Convention date]. Moulding depolarizers for dry batteries. - A machine for making dollies of dry batteries comprises preliminary and finishing moulds, in the first of which the depolarizer is slightly compressed and pierced by a punch. The depolarizer and punch are then transferred to the finishing mould where the depolarizer is further compressed from both ends while the carbon core is inserted and displaces the punch. Fig. 1 shows the two moulds 1, 2 and compression rams 3, 4 containing movable punches or plungers. The mould 1 as shown in end view in Fig. 3 is made in two parts 1<a>, 1<b> pivoted at 15 and carried by tongs which are pivoted on a cross-head 16 movable vertically on a guide 17. When the cross head 16 is lowered and then raised the two parts of the mould open and close on a mass of depolarizing material fed on to a revolving plate 38. The closed mould is raised until it is coaxial with the mould 2 whereupon the punch in the ram 3 moves forward and makes a hole through the depolarizer in the mould 1. The ram 3 then moves to force the depolarizer out of the mould 1 into the mould 2 whereupon the ram 4 moves forward so that pressure is exerted on both ends of the depolarizer. Within the ram 4 and in front of the plunger therein is a carbon pencil which is forced by the plunger into the hole in the depolarizer, displacing the punch. Movement of the ram 3 further compresses the depolarizer. Carbon pencils are fed into the ram 4 through a slot communicating with a magazine 20 into which the pencils are fed one by one from a container 21 by means of a drum 22 provided with grooves on its periphery. The rams and plungers are operated by cams 5, 6, 11 and an eccentric 12 all of which are actuated by a motor 29. The amount of depolarizer taken up by the mould 1 can be varied by altering the depth to which the mould dips into the mass on the plate 38. The finished dolly is ejected from the mould 2 by the ram 3 and is carried away on a conveyer 42.

[Class 136 (iii)] In a saddle support of the telescopic type adapted to enable the saddle to be lowered and the rider's feet to rest on the ground, the saddle pillar 7 is slidable in an outer tube 3 and is provided at the sides with two supports 9 pivoted or otherwise connected to it at 8, and each provided with two feet 9a, which normally, engage peripheral lugs or projections 6a on a collar 6 rotatably mounted on the tube 3, the collar 6 being rotated by a Bowden wire &c. 10 against the action of a spring 10a to bring the. feet 9a opposite recesses in the collar, thus permitting the pillar 7 and saddle to fall under the rider's weight, against the action of a spring 11. The supports 9 have channelled portions to slide over the projections 6a on the collar 6. The feet 9a normally engage depressions in the projections 6a and are disengaged by 'a slight upward movement of the pillar 7 under the action of the spring 11 when the rider takes his weight off the saddle, thus permitting rotation of the collar 6. The saddle pillar may be held in its lowered position by a catch.

Title: Apparatus for Controlling the Pneumatic Braking of a Train
IPC: B60T8/32
Filed: 1968-05-24
Abstract: 1,187,517. Electric control systems for brakes. MASCHINENFABRIK OERLIKON. 24 May, 1968 [1 June, 1967], No. 24968/68. Heading F2F. [Also in Division G3] Apparatus for controlling the pneumatic brakes of a train (which may have electric traction and braking) includes an Integral or Proportional Plus Integral control circuit. For a short train integral control is adequate, and the brake error signal (i.e. difference between actual and desired deceleration) is fed to an integrator circuit having a time constant such that the rate-of-change of air pressure in the train pipe is equal to or less than the rate-of-change of air pressure in any brake cylinder. In longer trains, the length of the brake pipe causes delayed rise in brake cylinder pressure and proportional + integral control is desirable, for stability, as shown diagrammatically in Fig. 4, where the braking error signal a be  is applied through a limiting amplifier to an integrator 15 and through a parallel ohmic channel 16. A more detailed arrangement of this circuit is illustrated in Fig. 7 with additional features. The error signal a k  is amplified at 21 to provide the proportional signal f a  and also fed to limiting amplifier 23, with limit diodes 25, 26, and thence to integrator 32, and the combined signals are amplified at 38, basically as in Fig. 4. Additional features: (i) a measuring trigger circuit 40 at the output, operates at a certain minimum output to correct for small pressure drops in the train pipe; (ii) for Downhill travel at Constant Speed a switching signal c from the train controller (not shown) biases diodes 29, 36, 37 to depress the limiting level of amplifier 23 and suppress the proportional signal f a -the proportional signal is replaced at the start of braking by a signal from trigger 48 (to " memory " 47 and capacitor 44) which decays in a few seconds. This signal is negligible in normal braking. Further, the switching signal c biases diodes 54, 55 to reduce the air brake signal ak by a fraction of the desired retardation a c , so that the electric brake operates on slight slopes.
