Title: Speed control for single-slice packaging apparatus
IPC: B65B59/02
Filed: 1971-07-16
Abstract: 1358901 Packaging apparatus for wrapping individual articles KRAFTCO CORP 16 July 1971 [30 July 1970] 33453/71 Heading B8C In a packaging machine, in-which individual articles such as cheese slices 24 are transported in equi-spaced relationship by an infeed conveyer 20 to a wrapping station 16 where they are wrapped in a tube of flexible wrapping material 14, in order to accommodate slices of different length in different production schedules without having to resort to changing the spacing of the conveyer lugs 22, and possibly its drive gearing, the speed of the drive 26 for the conveyer 22 is made variable so that it is periodically speeded up above that of the wrapping material to close effectively the gaps between successive slices just prior to their transfer to the wrapping material and periodically slowed down so that slices make contact with the wrapping material at the same speed as the latter. The drive 26 is readily adjustable so that the variation in speed of the conveyer can be altered to be compatible with the length of cheese slices in a particular batch. The drive 26 comprises a motor 34, Fig. 2, which, through chain and sprocket drive 44, 40 and spur gear 46 drives a differential system comprising a carrier gear 48 which is freely rotatable on a shaft 50 and which rotatably supports, in an opening 54, a planet gear 60 which meshes with a sun gear 62 fast on the shaft 50. A train of helical gears 66, 68, 74, 82 connects the shaft 50 with a shaft 84 which carries a sprocket 32 drive for the conveyer 22. A cam follower arm 58, connected to the shaft 56 of the planet gear 42, has a roller 88 received in a non-circular groove 92 in a cam plate 90 so that the planet gear 42 will rotate relative to the sun wheel 62 at portions of the track where the radius of the groove 92 is either increasing, or decreasing, to correspondingly decrease, or increase, the speed of the sun wheel 62 relative to the carrier gear 48. Different cam plates 90 can be easily fitted to accommodate differentlength slices. In order to adjust initially the exact time of the initial contact of the slices with the wrapping material the helical gear 82 is movable by a disc 120 and adjustment screw 110 axially along its splined shaft 100 and is rotated as it moves along the stationary gearwheel 72 to rotate the drive sprocket 32 of the conveyer 22. The screw 110 is lockable by a collar 124. Another conveyer can be driven by the duplicate gears 74a, 82a.

Abstract: 1430690 Making finned tubing UOP Inc 13 July 1973 [14 July 1972] 33511/73 Heading B3A [Also in Division F4] A method of producing a finned heat exchanger tube 10 comprises (a) forming by rolling, integral annular or helical fin convolutions from the material of a plain tube 10, said fins having a plurality of circumferentially spaced zones of reduced fin height and (b) bending the outer portions of all of the fins uniformly so that each convolution has its tip spaced at a small spacing from the side of the adjacent convolution to define therewith partially enclosed spaces 27 entending around the tube. As shown the spaced zones of reduced fin height are in the form of recesses or notches 18 formed either by rolling with a knurling tool longitudinally of the tube or by a cutting or grinding operation: bending of the fins is effected by drawing the finned tube through a suitably dimensioned die. In an alternative embodiment (Figs. 8-11, not shown) the finned tube is formed by advancing a plain tube over a mandrel having one or more helically extending grooves therein, the rolling operation being carried out by a plurality of sets of finning discs. The rolling operation deforms the tube material inwardly into the mandrel grooves thereby producing internal helical ribs in the tube, the fin portions overlying the ribs being of reduced fin height.

An upward extension f of the sleeve e connecting it to the metal wall d is provided with side apertures g. Screens h, f<1> on the anode stem and on the extension f slope downwardly towards the sleeve e. The insulator c may be protected from radiation from the anode stem by a sleeve around the stem. The parts f, f<1>, h may be of metal or insulating material and the opening g may form a siphon-like overflow, as in Fig. 4, to the gutter formed by the screen f<1>. The openings g may be replaced by spouts and these spouts or the flange p, Fig. 4, extend radially so that falling mercury is well spaced from the sleeve e and is delivered at parts where other condensed mercury drops. The extension f, Fig. 1, may carry a further screen similar to the screen f<1> and above the screen h and may have additional perforations above this further screen. An additional screen similar to the screen h is then arranged on the anode shank above this further screen.

Title: Process for the preparation preservation and distribution of  deep frozen cosmetically active preparations including  synthetic substances and products obtained thereby
IPC: A61Q19/00
Filed: 1973-07-19
Abstract: Many ingredients of cosmetic products are easily decomposed by oxidation or microbes on storage. The addition of preservatives, for example fungicides, antioxidants and the like, is disadvantageous because these materials may have a certain toxicity and may lead to irritation. A deep-frozen cosmetic product which may also, where appropriate, be formulated without preservatives is described herein. The deep-frozen cosmetic product according to the invention has biologically active cosmetic properties and contains a carrier material which is a synthetic substance which does not occur in nature, and furthermore an active ingredient which is an untreated cosmetically active ingredient which occurs in nature. It is particularly advantageous for the cosmetic product according to the invention to be in the form of single doses which are just sufficient for a single cosmetic treatment. Furthermore, a process for the production of the cosmetic products is also described.

Title: Apparatus for indicating axial thrust in a rotatable shaft
IPC: G01D5/20
Filed: 1956-11-12
Abstract: 832,529. Measurement of axial thrust. WESER A.G. Nov. 12, 1956 [Nov. 11, 1955], No. 34561/56. Class 40 (1). Axial thrust on a shaft, is measured by means of a parallel rod, fixed at one end relative to the shaft and having an electrical device at the other emitting signals in accordance with the movement of the rod relative to the shaft. As shown, the rod 3 is carried in a bearing 2 non-displaceably mounted on the shaft by members not shown. The free end of the rod operates to move the core 10a into the transformer 10, carried by the mounting 10c. The rod is contained in a casing filled with heatconducting fluid and has the same temperature coefficient of expansion as the shaft. Diaphragms 7, 8 or leaf springs 9 may be provided to prevent bowing due to centrifugal force. Preferably use is made of two such rods at opposite ends of a diameter of the shaft so that an average result may be taken to eliminate errors due to flexing. Fig. 3 illustrates the circuit arrangement in which the primaries 10b, 11b of the two transformers are fed from a high voltage A.C. source 14 over slip rings 12, 13 and a step-down transformer mounted on the shaft. Each transformer has two secondaries, corresponding pairs 10c, 11c; 10d, 11d being connected in series to provide induced voltages between slip ring 17 and slip rings 18, 16 respectively. These voltages are fed to a bridge arrangement, the unbalance current of which is a measure of the average movement of the two cores 10a, 11a. The unbalance current is amplified and fed to a cathode-ray tube with arrangements for filming the trace. The unbalance current is also fed via. a phasesensitive rectifier to a meter for indicating the mean thrust. The slip rings may, be adhesively fixed to a flexible plastic foil slightly shorter than the circumference of the shaft and held on by clips. The gap in the foil is used to accommodate the transformer leads.
