Title: Indicator means for adjustable trip on a weighing mechanism
Inventor: SCHELLENTRAGER EUGENE WILLIAM
IPC: G01G23/28
Filed: 1959-10-26
Abstract: 876,940. Weighing apparatus. ATLAS BOLT & SCREW CO. Oct. 26, 1959, No. 36153/59. Class 143 [Also in Group XIX] A weighing scale incorporates an arm 26 which is adjustably movable over a graduated dial 21 in a path generally parallel with that of the scale pointer 22, and means operative when the arm and the pointer are aligned to control the flow of material being weighed. Adjustably mounted on the arm is an indicator with a pointer portion 62b whose distance from and orientation with respect to the dial graduations is the same throughout its range of adjustment. As shown, the portion 62b of the indicator is integral with an arcuate portion 62a whose centre of curvature lies on the common rotational axis of the scale pointer 22 and the arm 26. This arcuate portion 62a is adjustably movable in a lot 26c (Figs. 5 and 6, not shown) in the arm 26 to which it is secured, after adjustment, by a screw 60. The control means actuated by alignment of pointer 22 and arm 26 is a mercury switch 44 (Fig. 3) carried by a cradle 42 which is tilted about a pivot 43 in response to axial movement of a shaft 57 whenever the pointer 22 and arm 26 become aligned, shaft 57 being pushed by a crank 55 moved by rotation of a shaft 52 to which it is attached. The shaft 52 is mounted in bearings 53 carried by the arm 26 and is turned by the engagement of a pin 50, carried by the pointer 22, with a butterfly trip member 51, carried by the shaft 52 (see Fig. 7). The above indicating and controlling means are enclosed in a dust-proof casing 25 having a transparent cover 30 and attached by hinges 25a to the weighing mechanism 13. The invention is described as applied to an automatic feed weigher in which the mercury switch interrupts a motor driving a vibratory or like feeder when the pointer 22 passes the arm 26, the relative position of arm 26 and pointer 62b being adjusted so that the travel of pointer 22 between the positions of arm 26 and pointer 62b corresponds to the amount of material fed to the weighing apparatus after the mercury switch is actuated.

Filed: 1973-07-30
Abstract: 1380208 Pulse radar HUGHES AIRCRAFT CO 30 July 1973 [29 Aug 1972] 36212/73 Heading H4D Incoming radar echo digital data is compared with past data stored in a cyclic memory and if the incoming data is within predetermined limits thereof it is not stored but otherwise is stored. Thus the size of the store is kept low since redundancy is eliminated. The predetermined limits may define a range/azimuth and/or elevation window, and that window may be vanishingly small. Each data unit entered into the store is given an "age code" which is decremented each time it is cycled through the memory, and the age code may intensitymodulate a display such as a type B or C display; and when the age code for a target has decremented to a predetermined value the data for that target is replaced by new data.

Abstract: 1416357 Adhesive tapes TORAY INDUSTRIES INC 9 Aug 1973 [8 Sept 1972 16 Oct 1972] 37787/73 Heading B2E An adhesive tape consists of an adhesive layer applied to a laminated base comprising a first layer of a propylene polymer film which is biaxially oriented and at least one other layer of a transversely oriented propylene polymer film, the melting point of the transversely oriented film being 0.5 to 10C higher than that of the biaxially oriented film, and its thickness being 1.2 to 5.0 times greater. A propylene polymer is defined as a polymer or copolymer mixture or copolymer containing at least 50 mol % of propylene units, or a propylene homopolymer. Preferably the biaxially oriented film is formed of ethylene/propylene copolymer with 0.5 to 2% by wt. ethylene, and the transversely oriented film is formed of ethylene/ propylene copolymer with less than 1.0% by weight ethylene. Other preferred physical properties are mentioned. The laminated base may be rendered more receptive to adhesives by surface oxidation using corona discharge, flame, or chemical oxidation, or by coating with a primer such as polyethylene-imine, chlorinated polypropylene, tetra-n-butoxytitanium, dichloro-diethoxy titanium, di-isopropoxy titanium bis acetyl acetoacetate or titanium tetrastearate. Suitable adhesives include natural rubber, synthetic rubber, (e.g. a mixture of polyisoprene, polyterpene and phenol/formaldehyde resin), polyvinylether, acrylic ester copolymers, and hot-melt adhesives, and they are applied from solution. A release layer may be applied to the opposite side of the tape, such layers including polyvinyl carbonate, partially esterified polyvinyl alcohol, octadecyl acrylate/ acrylic acid copolymer, vinyl stearate/maleic anhydride copolymer, and polymethysiloxane. The base is preferably formed by melt extruding the other layer of propylene polymer onto a film of propylene polymer which is longitudinally stretched, then transversely stretching the laminate.
