Title: Means and apparatus for measuring the evenness of textile yarns and the like
IPC: G01B11/08
Filed: 1929-12-04
Abstract: 343,215. Gauging-apparatus. WHITEHEAD (LAISTER-DYKE), Ltd., W. & J., STEWARD, C. O. M., and SMITH, C., New Lane Mills, New Lane, Laisterdyke, Bradford, Yorkshire. Dec. 4, 1929, No. 37088. [Class 106 (ii).] Regularity and periodicity variations in filaments &c. are measured by passing them at uniform tension in front of the slit of a thermopile so as to intercept radiant heat. The heat source may comprise a lamp, supplied from an accumulator and enclosed in a water-jacketed tube at one end of which is fitted the thermopile and adjustable slit. The thermopile is connected with a galvanometer G, scale readings of which are observed, or variations recorded photo. graphically, preferably using a revolving drum, the markings being subsequently measured with the aid of a second drum and a scale. The filament &c. passes from a bobbin B through a tension device D<0>, over rollers and through guide eyes to a drum W driven by clockwork &c. Two thermopiles &c. may be mounted at right-angles and the resulting cur. rents combined, or a thermopile may be rotated about the axis of the filament &c.

Abstract: 362,667. Radiators for motor-vehicles. MAYS, E. R., 24, Thornsett Road, Anerley, London. Dec. 9, 1930, No. 37089. [Class 29.] A group of flue tubes 21 extends upwards through the centre of the radiator from a chamber 7 in which a lamp 11 or gas burner may be placed during cold weather to prevent freezing. The flue tubes are preferably directed rearwardly at the top so as to discharge the combustion products through a gauze baffle 24 into the bonnet of the vehicle. The lower header 8 is formed with a recess to receive the lamp reservoir 10, and the lamp chamber may be closed by a vertically sliding door 13 having an observation panel 14, a finger grip 15, and apertures 16 for fastening screws. During warm weather the door is left open to produce a current of cooling air through the flues. Where a gas burner is used its base is formed with upstanding spring tongues engaging the walls of the lamp chamber. The divided parts of the lower header are connected by a channel 29 below the lamp chamber.

Title: Multiple towel dispensing device
IPC: A47K10/28
Filed: 1955-12-30
Abstract: 774,970. Dispensers for towelling. CHICAGO TOWEL CO. Dec. 30, 1955 [Oct. 7, 1955], No. 37456/55. Class 18. A towelling dispenser has a secondary towel available when the main towel is used up, the pulling out of the secondary towel for use winding up the end of the main towel on its take-up roll. The dispensing of both towels is controlled by a timing device. The main towel 20 passes from its unsoiled roll 20a over the usual drive and pinch rolls 30, 32, outside the dispenser and to the take-up roll 28 which is drive by a roll 34 chain connected to the roll 30. The secondary towel likewise passes over drive and pinch rolls 56, 59, but is formed into a loop which is held by a spring clip 60b, before it passes flush against the outside of the dispenser, to its take-up roll 24b driven by a roll 58. The shafts 34a and 58a, of the rolls 34 and 58 are connected by a chain 62 running over a sprocket 63 fast on the shaft 58a and a sprocket 64 having a one way rachet connection 66, Fig. 4, with the shaft 34a. When the main towel is being withdrawn, the rachet slips and the secondary towel mechanism is not effected. When the main towel is used up, its free end, pulled out of the dispenser, depends below it. The secondary towel - 24 is then pulled so that the portion held by the clip 60b is freed to give the necessary loop outside the dispenser. As the towel 24 is withdrawn the roll 58 drives the roll 34 through the chain 62 and rachet 66 and the free end of the main towel is wound up. The withdrawal of both towels is controlled by known timing mechanism operated by a member 30c on the shaft 30b of the roller 30. The mechanism comprises the usual suction cups 48b, 48a, the latter connected to a stop 46b which, when the cups are engaged, prevents rotation of the roller 30 by being in the path part 30e of the member 30c. The towels 20 and 24 are replaceable through hinged doors 12 and 14 respectively.

Filed: 1958-11-26
Abstract: 867,726. Electric weighing machines. TOLEDO SCALE CORPORATION. Nov. 26, 1958, No. 38206/58. Class 40 (1). [Also in Group XVIII] An integrating conveyer weighing machine comprises a strain gauge device for determining the loading on a continuously moving conveyer belt, feeding the signal to a ball and disc multiplier together with a speed proportional to the belt speed, and supplying their product to a counter which indicates total weight carried by the belt. As shown (Fig. I), an endless belt 3 rests on weighing rollers 2, 4 associated with the loaded and unloaded parts of the belt. The rollers are suspended by equal arms about a fulcrum 6, the difference in weight producing a displacement of an extension 9 attached to a strain gauge cell 8 connected in a balancing bridge circuit (Fig. II). The bridge unbalance current drives a motor 10 which rebalances the circuit by moving the slider 34 of a potentiometer 36, the extent of movement being indicated by a pointer 41, simultaneously moving a rod 11 attached to the ball housing 14 of the ball and disc multiplier 12. The belt speed is sensed by a pulley 103 and fed via selsyn link 19, 21 to the disc 13 of device 12, the rotation of output cylinder 16, which is proportional to the product of instantaneous weight and speed of the belt, being fed to a counter 27 through a differential 24 which removes a constant deliberately introduced into the output from the strain gauge cell 8 to prevent the ball housing 14 from being located at the centre of disc 13. Mechanical construction.-The weighing beam assembly is supported by two vertical rods 48 (Figs. III, IV), attached to the frame 7, and comprises twisters 51 joined by a shaft 52 and rotatable about knife edges 51. The shaft 52 carries an adaptor 53 supporting a lever 55 on which a counterweight 56 is adjustably supported to counterbalance the dead weight of the system, and an extension 9 attaches the shaft to the load cell 8, which may incorporate an overload guarding mechanism 61. Rods 70 attached to one side of twisters 51 support plates 73 and brackets 77, carrying between them the upper roller 2. Rods 72 attached to the other side of twisters 51 support plates 88 and brackets 92, carrying between them the lower roller 4.

In a rear wheel suspension for a front wheel drive vehicle, each rear wheel 10 is mounted with negative camber on a suspension link 11 pivotable about an axis 18 which is inclined forwardly and outwardly at an acute angle to the longitudinal centre plane 17 of the vehicle (Fig. 1) and, in projection on a plane extending transversely of the vehicle, is located above the wheel's rotational axis 16 (Fig. 2) in the entire region between the plane 19 of the wheel and the point of intersection (not shown) of the wheel axis 16 and the road surface. The pivot axis 18 preferably lies in a horizontal plane and intersects the plane 19 of the wheel at a point 20 (Fig. 3) on a line 24 joining the ground contact point 21 of the wheel with a point 20 which divides a horizontal line through the vehicle's centre of gravity Sp proportionally to the braking forces BV, BH at the front and rear wheels. The link 11 is connected to the' vehicle frame 15 about the pivot axis 18 by means of resilient bearings 14 which are stiffer radially than axially and have their axes 25 intersecting forwardly of the axis 18 to maintain the position of the latter when lateral forces act on the wheel. A spring unit 31 comprising a helical spring arranged coaxially about a shock absorber is connected to the link 11 below the plane of the axis 18 and is disposed along an inclined axis 32 which projects upon the plane of the link 11 at right angles to the axis 18, progressive spring action being thereby obtained.
