Filed: 1919-03-28
Abstract: 145,847. British United.Shoe Machinery Co., (United Shoe Machinery Corporation). March 28, 1919. Heel seats, shaping by cutting.-The invention consists in a machine for operating on the heel end of a shoe sole to prepare it for attachment to a heel: The heel end is convexed as shown in Fig. 3, leaving a shoulder as shown. The sole and upper are held between jaws 75, Fig. 2, which enter the crease between sole and upper and a roll 7 depresses the middle of the heel seat so that a horizontally sliding knife 5 removes a horse shoe shaped piece of leather. The shoulder is produced by reciprocating vertical knives 155, the angle of which. can be varied. The knife 5 and the roll 7 are carried by a sliding block 3 which is operated by a rack 159, Fig. 1, and a pinion 161. The knives 155 attached to the slide 131 are also driven by the same pinion which engages a rack 163 reciprocated by a rod 169 engaging a cam on a shaft 73. The knife 5 is caused to start before the roll 7 by means of a slip device which causes the roll to lag. The roll 7 is carried by a lever 9, Fig. 1, pivoted to a link 13 itself pivoted at 15 to the sliding block 3.-The forward part of the lever 9 is pivoted to a link 17 pivoted to a two part lever 21, 23 both parts of which are hinged at 25. A part 121 on one lever bears at 123 on the other and both are pressed down by a resilient bar 27. The rear end of the lever 23 is attached to a toggle 33, 35 which is operated by an arm 41 fixed to one of the levers 35. An arm 51 is depressed by a pivoted lever and rod 69 driven by a cam on the driving-shaft 73. The depression, of the arm 51 operates the lever 41 so that a roller 45 enters an adjustable cam-track 53. This straightens the toggle 35, 33 so as to allow the bar 27 to depress the roller 7. When the slide 3 moves, a certain amount of lag is provided by a catch in a slide 61 slipping out of one slot 64 into another 67, the reverse action occurring on return movement. The slide 61. is attached to the link 13 by a link 57. The knives 155 are adjusted transversely by levers attached to a wing nut 153. They are adjusted vertically by a slide 145 and a nut 143. The slide 131 is pivoted at 135 to give angular adjustment.. The shoe is held in the crease between sole and upper by jaws 75, Fig. 5, pivoted at 77 and adjustable longitudinally by a pivoted cam 105 which has a slot engaging a roller 101 on the slide carrying the jaws. The cam is adjusted by , a spring handle 111 engaging a number of slots in a quadrant. The rear end of one of the jaws is attached to an adjustable spring 83. The jaws are opened by a parallel-motion lever 91 operated by a rod attached to a treadle. A jack 115, Fig. 1, for holding a shoe is provided with a spring pin 129 for pressing the work upwards.

Abstract: 1,194,781. Axial flow turbomachines. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Feb. 20, 1968 [Feb.27, 1967], No. 8153/68. Heading F1T. An axial flow multi-stage turbine or like machine has an undivided drum carrying the rotor blades and a stator formed from axially abutting undivided rings each carrying an annular series of stator blades, the stator blades terminating in shrouds which co-operate with platforms on the rotor blades radially outwards of their roots to form the radially inner boundary of the working fluid passing through the machine. In the case of a compressor, Figs. 1, 2, the undivided rotor drum 1 has radially thickened portions 3a each carrying an annular series of blades 5 by engagement of their roots 11 in axial slots 9. The roots 11 are locked in position axially by keys 24, the latter being held in position during assembly by rings 26 fitting in annular slots 25. Each blade 5 has a platform 15 spaced from its root by ribs 17, 19, adjacent platforms 15 co-operating with the annular shrouds 8 on the stator blades 4 to form the inner boundary of the flow path. The outer boundary is formed by undivided rings 6 which inter-fit at flanges 6a, 6b and support the respective series of stator blades 4. A further casing may surround the rings 6. Interstage leakage is reduced by a diametrically split annular member 18 bolted at 12, 14 to a rib 10 on each shroud 8 and co-operating with labyrinth projections 7 on the rotor drum 1. The ribs 17 prevent leakage between the blades 5 radially inwards of platforms 15. During assembly the rotor and stator are built up stage by stage in an axial direction from one end of the machine. In a modification, Fig. 3 (not shown), the stator shrouds 8 do not support annular sealing members 18 and interstage sealing is effected by ribs (30) carried by platforms 15 and co-operating with the shrouds 8. In a further modification, Figs. 4 to 6 (not shown), the labyrinth sealing projections are not formed directly on the rotor drum 1 but are formed on ring segments (40) fitting in axial slots (41) in the drum 1 between the rotor stages. The segments (40) have flanges (40a) to prevent leakage between adjacent rotor blade roots 11. In a still further modification, Figs. 7 to 9 (not shown), the labyrinth projections are formed on one piece rings (72) which have dogs (72a, 72b) engaging in annular recesses (71a 71b) in the rotor drum 1 adjacent the blade mounting slots 9.

Title: Fuel injection systems for internal combustion engines

Filed: 1975-02-28
Abstract: 1491913 Regulating I C engine fuel injection ROBERT BOSCH GmbH 28 Feb 1975 [2 March 1974] 8356/75 Heading F1B [Also in Division G3] An internal combustion engine fuel injection system includes a sensor e.g. an NTC resistor that measures the engine temperature so as to control the fuel injection in accordance with engine temperature during start and warm-up phases of the engine. The sensor has an associated switch which, during hot starting of the engine, initiates the feeding of additional fuel to the engine if it does not start in a pre-set interval after an engine starting switch is actuated. In the embodiment, pulses from an engine driven cam Z trigger a monostable circuit 1 whose period is proportional to the measured air-flow to the engine. OR gate 16 receives the output of circuit 1 and controls the engine fuel injection using solenoid 18, the injection period being increased, upon starting or warm up of the engine, by a further input to gate 16. This input, from a switching circuit including transistors 4, 9 and 13, is dependent upon the engine temperature as detected by NTC resistor 11. Upon starting, switch 22 is closed, and if starting motor 23 is energized for an interval greater than a value dependent upon the period of monostable circuit 42, and also if the engine coolant temperature is above a given value, i.e. the engine is hot running, a transistor 28 in series with NTC resistor 11 is blocked for a period dependent upon the unstable interval of monostable circuit 55. Thus the switching circuit including resistor 11 simulates a low temperature condition, and provides the additional fuel injection, although the engine is hot running. The use of the engine coolant temperature sensor 24 ensures that transistor 28 can only be blocked, and the low temperature simulated, if the engine is hot running.
