Title: Improvements in straw blades, ribbons of straw blades or straw sheets for tipping cigarettes
IPC: A24C5/56
Filed: 1925-10-02
Abstract: 257,424. Przedecki, L. Oct. 2, 1925.

Title: Device for cold Starting for Internal Combustion Engines
IPC: F02D41/06
Filed: 1968-05-23
Abstract: 1,164,747. Electric control systems. ROBERT BOSCH G.m.b.H. May 23, 1968 [May 24, 1967], No.24569/68. Heading G1N. In an electronically controlled petrol injection system for an internal combustion engine, having an electromagnetically actuatable fuel injection valve 83 for each cylinder controlled by opening pulses produced by a monostable multi-vibrator 28 in response to triggering pulses from the actuation of cam-operated switches 63, 64, an additional amount of fuel for cold starting is injected by applying additional triggering pulses to the monostable multi-vibrator 28 from an astable multi-vibrator 24 which is set oscillating in response to closingthe engine starter switch 21. The frequency of oscillation of the astable multi-vibrator 24 gradually decreases as the engine warms up, the temperature of the engine being detected by an N.T.C. resister 23 forming a bridge circuit with resistors 58, 46 and 47. When a predetermined temperature is reached, oscillation stops altogether. A normally closed switch 22 is arranged to be opened when a predetermined pressure in the induction pipe or a predetermined engine speed is reached, thereby reducing the magnitude of the pulses transmitted by capacitor 55 to a level which cannot unblock diode 60 so that the astable multi-vibrator 24 cannot then trigger the monostable multi-vibrator 28. Diode 33 protects the circuit against voltage surges from the starter solenoid 73 when the starter switch 21 is switched off. The duration of the opening pulses produced by the monostable multi-vibrator 28 is controlled in dependence on the pressure in the induction pipe by displacement of the iron core 87 of a transformer.

Title: Apparatus for the continuous automatic discharge of mud from steam boilers and heaters of liquids
IPC: F22B37/48
Filed: 1928-08-28
Abstract: 305,977. Piccardo, C. Feb. 13, 1928, [Convention date]. Sediment-collectors and settling-chambers.-A mud separator comprises two coaxial groups 15, 16, Fig. 3, of frustums of cones around a descending inlet pipe 13 so that the shortest ascent for the muddy water to the outlet 14, 19 is through an annular zig-zag space. The mud separates by centrifugal force and is drawn out between the cones 16 and down near the shell 2 due to the cooling of the water by contact with the shell. In a smoke-tube boiler, Fig. 1, pipes 3, 7 respectively insulated and ribbed connect the water space to the mud separator 2 below the water level. The pipes 3, 7 lead to the lower side of non-return valves 5, 6 normally held open by their weight, the water circulation being insufficient to close them. When the cock 11 is opened to discharge mud, the flow of water closes the valves 5, 6 automatically so that the separator does not remain at boiler pressure. When the cock 11 is closed, pressure is produced in the separator through a slight cut in, or incomplete grinding of, the valves 5, 6 which thus open. For washing out the separator, the valves 5, 6 are opened by rods 20, 21 and the cock 11 is opened. Air-discharge and testing cocks 8, 10 are provided; and the speed of circulation is regulated by the valves 3<1>, 4.

[Also in Division B6] Book jackets comprising a strip of paper of a width approximately equal to the height of the book to be jacketed, and a strip of transparent foil e.g. polyvinyl chloride foil, which is wider than the paper and the projecting margins of which are folded over and stuck to the back of the paper strip, are produced from composite material made in a machine having (a) means for supporting reels 10, 12, Fig. 1, of the paper and foil, and drawing the webs 14, 21 of material through the machine (b) means 15, 17 for applying stripes 19, Fig. 4, of glue to the edges of one surface of the paper 14, (c) guiding means 16, 25, 26 for bring- ing the webs together with the uncoated side of the paper 14 in contact with the foil 21, (d) means for folding the projecting marginal edges of the foil over the paper strip into contact with the glue stripes and (e) means for pressing the folded marginal edges against the glue stripes 19. The guide roller 25 has circumferential grooves in line with the stripes 19 so that it does not contact the stripes. After leaving the guide rollers 25, 26, the webs 14, 21 pass between rollers 30, 33 the upper one of which has cone-shaped ends 35, Fig. 4, with which the edges of the foil are engaged so as to commence the turning in of the foil edges. More than one pair of such rollers may be provided. Subsequently the partially-turned in edges pass beneath blocks 32 shaped to form, in association with a flat bed 57, narrowing slots, Fig. 5 (not shown), so as to complete the folding over of the foil edges. The devices 35, 32 may be replaced by sheet-metal elements which progressively curve through 180 degrees to turn-over the side edges of the foil. The turned-over edges are pressed down on to glue stripes by rollers or discs 41 . . ., 44, and the webs then pass to feed rollers 47, 48 and are wound into a roll 49 or cut into lengths. The various rollers, other than rollers 47, 48 may be driven or may be idlers. If the foil reel 12 has an interleaving strip 22, this is rewound on roll 49 with the webs after passing over guides 23, 24. The devices at one side of the web paths may be adjustable for operating on webs of different widths. Feeding webs. The core on which each supply reel 10 or 12, is wound is wider than the webs and is loosely supported on a fixed shaft 11, 13. One or more levers 50, Fig. 6, which may be partially supported by adjustable springs rest on the cores to brake them. If one lever 50 is provided at each end of the reel, the levers serve also to centralize the reel on the core. The shafts 11, 13 may be screwthreaded so that as the cores rotate they are urged towards one of the levers 50. The webfeeding rollers 47, 48 are surfaced with friction material such as foam rubber.
