Title: Improvements in or relating to machines for rolling paste or dough
IPC: A21C1/08
Filed: 1935-05-25
Abstract: 457,334. Rolling dough. MORETON, W., Shandon, London Road, Leicester. May 25, 1935, No. 15296. [Class 87 (ii)] Relates to paste or dough rolling machines in which the dough is passed to-and-fro between reducing rollers and comprises means for feeding the dough from the reducing rollers at a speed greater than that at which it is fed to the rollers. The dough is fed to and from the reducing rollers 1, 2, Fig. 1, by endless conveyers 7 passing over tables or supports 6 and around rollers 89. The rollers 9 are driven by one or other of a pair of chains 15, 16, Fig. 6, which are themselves driven by sprocket-and-chain gearing from the operating handle 3 connected to the lower reducing roller 1. In the position shown in Fig. 1, if the handle 3 is rotated in an anticlockwise direction, a projection 36 will engage a spring-pressed lever 37 and thereby move a slide 33 to the right. Each movement of the slide operates a clutch device whereby the chain 15 or 16 which previously drove the conveyer rollers 9, idles, while the other chain drives. The sprockets on the shafts of the rollers 9 are of different sizes, and the arrangement is such that the conveyer leading the dough from the reducing rollers 1, 2 travels at a speed greater than that of the feeding conveyer. When the direction of rotation of the operating handle 3 is again reversed, the projection 36 acts on another lever 37 normally held in the raised position by a spring, whereby the slide 33 is moved to the position shown. Means may be provided for dusting flour on to the dough, the reducing rollers, or the conveyers. Specification 433,386 is referred to.

Title: Improvements in or relating to variable speed gears
IPC: B23Q5/14
Filed: 1957-05-16
Abstract: 815,560. Change-speed control. WERNER, H. H., and RUDIGER, F., [trading as WOHLENBERG K.G., H.]. May 16, 1957 [May 19, 1956], No. 15525/57. Class 80 (2).  Change-speed control mechanism for change-mesh change-speed gearing in machine-tools such as lathes &c. comprises striker forks 24 ... 28, Fig. 3, selectively locked to a shaft 23 in such a way that only one fork can be slidden left or right from the position shown at a time to establish a ratio, gears 45, 46 connecting the shaft 23 to a shaft 22 carrying pins 29 ... 33 selectively engaged by rotation of the shaft with grooves 67 in the striker forks, axial movement of the shaft 22 sliding the unlocked fork to establish the ratio. The striker forks 24 &c. are provided with axially aligned grooves 44. Pins 34 ... 43 are circumferentially spaced 36 degrees apart around the shaft 23, each consecutive pair of pins being situated at opposite sides of the striker forks. When a groove 44 in a striker fork is opposite one of the pins, e.g., as shown, the groove 44 in the striker fork 24 is opposite the pin 34, then the striker fork can be slidden axially in one direction only, its groove receiving the pin. The other striker forks are held locked in position by their associated pins. The gear 46 is meshed by a worm 47, Fig. 4, fast with a knob 63 turned to rotate the shafts 22, 23 and preselect a desired ratio. The knob 63 cooperates with a dial indicating the ratio selected. Axial movement of the shaft 22 to establish the preselected ratio is effected by turning a hand lever 53 fast with a sleeve 54 and a two-armed lever 55. Pins 56, 59, Fig. 5, at opposite ends of the lever 55, co-operatewith grooves in sliding rods 57, 60. Arms 58, 61 fast with the sliding rods 57, 60 carry bushes 48, 49, Fig. 3, sliding on the shaft 22. Thus anti-clockwise motion of the sleeve 54 in Fig. 5 will separate the two arms 58, 61 and, with them, the two bushes 48, 49. As shown in Fig. 4, five axial grooves 64 and five axial grooves 65 are circumferentially spaced around the inside of the bushes 48, 49 and co-operate with pins 50 ... 52, Fig. 3, on the shaft 22. The arrangement is such that preselection of a ratio, by turning the knob 63 and shaft 22, positions one or other of the pins 51, 52 opposite to a groove in its associated bush. This bush can then be slidden freely axially along the shaft 22, while the other bush is held axially between its two associated pins. Thus separation of the two bushes 48, 49 by turning the hand lever 53 causes one of the two bushes to move the shaft 22 axially and establish the ratio. As a modification, one of the bushes 48, 49 and the associated sliding rods 57, 60 can be dispensed with, axial movement of the shaft 22 in opposite directions then being effected by turning the hand lever 53 one way or the other. The change-speed gearing comprises a shaft 10, Fig. 2, fast on which are gears 11 ...16 selectively engaged by one or, other of five double gears 17 ... 21 splined on a shaft 66.

Title: Apparatus for detecting faults in a moving textile fabric
IPC: D04B35/10
Filed: 1950-06-23
Abstract: 672,152. Photo-electric control apparatus. CELANESE CORPORATION OF AMERICA. June 23, 1950 [June 25, 1949], No. 15771/50. Class 40 (iii). Apparatus for detecting faults in a moving textile fabric comprises a carriage reciprocated across the fabric and carrying a pair of cells viewing different portions of the fabric, the cells feeding an amplifier to give a warning or stop the fabric when the illumination of one cell changes with respect to the illumination of the other. Preferably the warning or stopping occurs only when the rate of change of the relative illumination is low. A knitted fabric 21, Fig. 3, is drawn beneath a carriage 31 reciprocated at right angles to the direction of movement of the fabric. Light from the fabric is focused on two cells 39, Fig. 6, on the carriage, each cell feeding an amplifier 41 whose outputs are opposed in transformer 66 and condenser 65<SP>1</SP>. The cells are shielded by magnetic and electrostatic shields 63, 64 and each is enclosed in an inner shield 65 connected to the cathode of the corresponding valve 41. For a perfect fabric, the outputs of the two cells are equal and condenser 65<SP>1</SP> has no charge. When one cell scans a defect, the outputs become unequal and condenser 651 acquires a charge which disappears when the cell has passed the defect; this evanescent charge produces equal and opposite pulses in transformer 66, the magnitude of the pulse depending on the rate at which the condenser charges and discharges, i.e. on the nature of the defect. The negative pulses only are passed by a suitably biased valve 69 and further amplified by valve 70, condensers 71 by-passing variations above a predetermined frequency. The emergent pulses, if above a predetermined amplitude make valve 72 conducting to charge condenser 74 which retains its charge for a period sufficient to make valve 76 non-conductive and thus release the relay 77 to stop the knitting-machine. The level at which valve 72 conducts is adjusted by varying resistance 73. A contact 49 is closed at the end of each traverse of the carriage to prevent the operation of the stopping mechanism when the edge of the fabric is being scanned.
