Title: Improvements in or relating to weight-and-height measuring apparatus
IPC: G01G19/50
Filed: 1939-01-21
Abstract: 512,747. Height-measuring devices. FLEISCHER, D. Jan. 21, 1939, No. 2169. [Class 106 (ii)] [Also in Group XVIII] In a personal height and weight measuring machine the height and weight measuring means conjointly control means adapted to be adjusted to various angular positions for indicating the relation, for example overweight, normal weight or underweight, between the height and weight of the person. The weight of a person on the platform 13, Fig. 1, operating through usual weighing mechanism, displaces a rack 27, Fig. 3, a vertical distance dependent on the weight The rack sets a weight-indicating dial 29 read through a window 30, and also by means of a pinion 28 depresses a rack 33 connected by a pin and slot 43, 44 to a plate 41 pivoted at 11a upon a rack 11c. The rack 11c is set by means of a pinion 16 engaging a height-measuring member 11 extending above the cabinet and carrying an arm 12 which is lowered manually on to the person's head. The height is indicated at a window 19 on. a dial 18. If the person is of normal weight for his or her height the settings of the racks 33, 11c are such that the plate 41 remains horizontal. If however the person is overweight or underweight, the plate 41 is tilted one way or the other and one or other of two mercury switches 48, 49 is closed. A pointer 45 on the plate 41 indicates on a chart 46 the normal, under, or overweight condition, and the mercury switches when closed operate through relays to energize one or other of two electromagnets utilized after insertion of a coin to issue either ah overweight or an underweight ticket bearing appropriate indicia relating for example to diet. If the person is of normal weight the relays are not operated and a third electromagnet for normal tickets is energized. To prevent use of the apparatus except upon insertion of a coin a. pair of opaque cards normally obscure the height and weight dials but are removed by an electromagnet when a switch is closed by operation of the coin slide. To render the apparatus suitable for either men or women, the rack 33, Fig. 3, may be set to either of two lengths by rotating a finger knob 40, Figs. 1, 3, connected by a flexible cable to an interposer cam 38. The different lengths of the rack 34 affect the inclination of the plate 41 and its consequent indications. Instead of using an arm 12 for measuring the height of the person, the member 11 may carry a sight'passage 78, Fig. 9. When the sight passage comes opposite the level of the user's eye so that he may look through, his height is correctly indicated by the height dial 18.

Filed: 1945-01-27
Abstract: 588,069. Cooling cylinders and exhaust. ARMSTRONG, G. J., and NICHOLSON, L. F. Jan. 27, 1945, No. 2188. [Class 7 (ii)] The cooling air for an engine surrounded by a cowling 16 is divided into separate streams for the barrels and heads of the cylinders, and an ejector action is produced on the flow by discharging exhaust gas thereinto. Cooling air entering at 18 is divided by rectangular ducts 22 having a constant cross sectional area into portions for each cylinder. The air is lead by elbow ducts 24 into junkheads and by shrouds 23 to the cylinder barrels, the shrouds closely enveloping the cylinder fins. The ducts 24 extend to the head fins and further ducts 25 take the air to ducts 34 into which exhaust nozzles 31 open. Perforations 24a allow some of the air to escape and cool the sparking plugs 14. The air is drawn back into the main air stream through perforations 32a in the wall of the air duct adjacent the nozzle 34. The exhaust pipe 12 is surrounded by a cooling air passage 30. The cylinder shrouds are divided so that air flows above and below the inlet and exhaust port belts to ducts 26, 27 which unite and receive the mixed air and exhaust issuing from the nozzle 34 thereby effecting a further ejector action. The mixed air and exhaust finally issues through isolated sections 33 of an annular exit from the cowl which are controlled by flaps 35. The sections 33 may however extend to the rear of the engine nacelle. The air may be drawn in to the front of the cowl by an engine-driven fan, curved individual passages being arranged behind the fan to accommodate the swirl pro- . duced thereby.

Abstract: 930,347. Building tyre head cores. NATIONAL-STANDARD CO. Jan. 20, 1961 [Jan. 21, 1960], No. 2423/61. Class 144 (1). [Also in Groups XXXV and XXXVII] Apparatus for building the bead core of automobile tyres and the like comprises a supply reel 11 of wire 10, the wire 10 being drawn off the reel 11 by a haul-off motor 17 through an extrusion head 13 where it is coated with rubber, the rubber-coated wire 15 being fed to a storage device in the form of a festoon having a fixed set of sheaves 24 and a movable set 27, the coated wire 15 being intermittently drawn from the storage device by a winder motor 31, the haul-off motor 17 being controlled to feed the coated wire 15 to the storage festoon at varying rates according to the position of the lower set of sheaves 27. The haul-off motor 17 may be controlled either by voltage variation on the field or armature or by a Ward-Leonard device. Assuming an initial condition wherein the storage festoon in full the sheaves 27 will be at the bottom of their travel with a member 76 causing switch 78 to be operated to stop the motor 17 thus stopping the feeding of the coated wire 15 to the storage festoon. Operation of the winder motor 31 to draw off an amount of wire 15 to build the bead core cause the lower sheaves 27 to move upwardly towards the fixed sheaves 24. This movement causes anti-clockwise movement of a chain 43 whereupon a peg 62 engages a fork 63 to move a slider of a potentiometer 65 to vary the voltage distribution across a potential divider whereby the voltage applied to the motor 17 causes it to speed up and increase the rate of feed of the wire 15 to the storage festoon. Further upward movement of the sheaves 27 causes the peg 62 to operate a switch 70, the operation of this switch causing a resistor to be inserted into the potential divider and also to cause a pilot motor to run to move the slider of a further potentiometer associated with the potential divider the effect of these operations being to alter the voltage distribution to cause the motor 17 to decrease in speed and decrease the rate of feed to the storage festoon. Still further upward movement of the sheaves 27 will cause the member 76 to operate a switch 82 whereupon a second resistor is inserted into the potential divider and the pilot motor caused to run to move the slider of the further potentiometer in the opposite direction whereupon the motor increases speed to increase the rate of feed to the storage festoon. At the top of the travel of the sheaves 27 a switch 85 is operated to stop the winder motor 31. The member 22 causes the motor 17 to stop if excessive slack exists in the feed to the storage festoon whilst the member 28 stops the motor 31 if the wire being taken from the storage festoon breaks, a brake 47 being energized to stop unwinding of the festoon. Specification 930,348 is referred to.
