Abstract: 1,230,014. Waste compacting device. COMPACTOR CORP. 18 April, 1968 [9 Aug., 1967], No. 18346/68. Heading B8C. Apparatus for compacting waste has two rams reciprocal in a housing containing the waste, the two rams being arranged to reciprocate together until the back pressure generated by the waste exceeds a predetermined value when one ram is activated to reduce the back pressure and allow further joint reciprocation. A housing 10 contains a primary ram 18 reciprocated by two fluid motors 40 and a secondary ram 19 slidable axially within the main ram by a fluid motor 42 secured to the primary ram skirt. When waste is detected in a shoot 12 by a sonic or light beam and switch arrangement 70 fluid is pumped to the motors 40 to reciprocate the rams 18, 19 together and compact the waste material into the narrowed portion 24 of the housing. When the back pressure reaches a predetermined level sensed by a sequence valve (100, Fig. 10) fluid is also pumped to the motor 42 to activate the ram 19. Advancement and withdrawal of this ram forms an aperture in the wall of compressed material and so reduces the pressure of the material. The two rams then continue reciprocating together. Limit switches 66, 67, 68 control the movement of the rams which can be cylindrical or non-cylindrical according to the shape of the housing. Deodorizers and insecticides can be sprayed from an inlet 74. A waste receiving can 14 can be placed at the end 80 of the housing, the latter having an interlock switch 112 so that operation of the apparatus is prevented when there is no can in place. Sawteeth to slice the compacted waste are provided on a head wall 26 of the ram 18. In an alternative embodiment the secondary ram 124, Fig. 8, is connected to a screw drive 120 and is encircled by a compression spring 122 with one end resting on its base and the other on the front wall of the primary ram 118. Upon rotation of the drive 120 by a reversible motor 127 the secondary ram 124 moves forward and the primary ram 118 is moved forward by the compression spring.

Abstract: 1,239,555. Extraction of saponins and sapogenins. NATIONAL RESEARCH DEVELOPMENT CORP. 6 Aug., 1968 [30 Aug., 1967], No. 39765/67. Heading C2U. Sapogenin-affording vegetable materials are treated, prior to the recovery of saponins or sapogenins therefrom, with a regulator which is capable of modifying normal plant metabolism or growth and which comprises at least one substance selected from: (a) naturally occurring plant growth regulators (e.g. 3 - indoleacetic acid, the gibberellins, 6 - furfurylaminopurine, traumatic acid, abscissic acid); (b) synthetic plant growth regulators (e.g. acyclic and cyclic acids, esters, salts and amides and a wide range of herbicides); (c) sulphydryl inhibitors (e.g. derivatives of lactic and maleic acids and or indole, iodoacetic and iodosobenzoic acids and odoacetamide); (d) regulators of lipid metabolism (e.g. "Vasolastine" (Trade Mark)); (e) regulators of steroid metabolism (e.g. atromid- S, triparanol and soya bean preparations; (f) natural and racemic amino-acids; (g) vitamins of the B-group, rutin, and watersoluble derivatives of vitamins A and tocopherol; (h) growth factor analogues (e.g. α- picolinic acid hydrochloride, DL-desthiobiotin and allyl - DL - glycine); and (i) antibiotics of the penicillin, griseofulvin and chloramphenicol classes. The regulator is preferably applied in an amount of 50-100 p.p.m. based on the air dry weight of the vegetable material and may or may not be removed prior to saponin/sapogenin recovery. The regulator may be added as a pure chemical substance, or in the form of a commercial formulation. The treatment is conducted under non-hydrolytic conditions. Sapogenins (e.g. diosgenin) are recovered from the treated material either by hydrolysis and extraction of the hydrolysate with a solvent or by extraction with a saponin solvent (e.g. methanol) followed by acid hydrolysis. Additional pre-recovery treatments which may be effected before, during or after the treatment with regulator are: (i) incubation in an aqueous medium; (ii) defatting; (iii) treatment with saturated hydrocarbons of at least six carbon atoms (see Specification 1,198,626); (iv) treatment with steroid precursors (e.g. mevalonic acid or squalene); and (v) incubation with degrading enzymes (e.g. cellulose, pectinase). The vegetable material may be of the families Dioscoreaceae, Liliaceae, Amaryllidaceae, Leguminosae, Solanaceae, Balanitaceae and Zygophyllaceae. Specified genera are Dioscorea, Tamus, Agave, Aletris, Asparagus, Similax, Trillium, Yucca, Trigonella, Trifolium, Solanum and Balanites. The material may or may not be comminuted prior to treatment.

Abstract: 1296359 Polarity reversing; switching circuits; colour television RCA CORPORATION 5 Dec 1969 [16 Dec 1968] 59651/68 Headings H3T and H4F Respective ends X, Y of the secondary of a transformer T1 are alternately connected to a reference potential by a switching circuit so as to repeatedly reverse the phase relationship between the output and an input signal. Switching is effected by alternately rendering diodes D1, D2 conducting, by a multivibrator comprising transistors VT1, VT2. The arrangement is applied to switching the (R-Y) component of the chroma signal in a PAL system television receiver, or the subcarrier reference signal, and the multivibrator is switched by the line sync. signals. The effect is to remove the repeated phase reversal inherent in the PAL system. As each diode D1, D2 conducts it effectively earths (actually + 2V.) its associated h.f. decoupling capacitor C1, C2 so that the output signal, taken from the slider of balancing potentiometer P1, is alternately derived from X and Y. Phasing of the multivibrator is controlled by a phase detector circuit comprising diodes D5, D6 and resistors R9, R10. The output of a " burst detector " in the receiver is connected as shown, and if the phase is incorrect the output from R9, R10 turns on a transistor VT3 which inhibits the multivibrator until phasing is correct.

Title: Apparatus for winding packages of synthetic plastic tape

Filed: 1969-03-18
Abstract: 1310521 Winding tape into package form; flyers JAMES MACKIE & SONS Ltd 13 March 1970 [18 March 1969] 14201/69 Headings D1D and D1J This invention relates to the winding of packages of synthetic plastic tape by rotating a support for the package and traversing the tape onto the support, or by winding the tape onto a non-rotating support by means of a flyer, the flyer and the package having relative axial movement.  In both instances the tape traversing member 11, Fig. 3, terminates in an extension 13 that presses against the package, the extension having a tape guide slot 15 for controlling lateral movement of the tape and a nose portion 14 that engages the surface of the package over a width less than that of the tape guide slot 15, the end of the member 11 adjacent the extension 13 being capable of elastic displacement in a direction axial of package by a distance equal to at least half the width of the tape guide slot 15. The winding of a package with tape tends to produce depressions and ridges. When the nose portion 4 enters a depression the aforesaid flexibility permits the nose to remain in the depression whilst flexing of the member 11  takes place thus allowing additional turns to be wound into the depression to erase it. The stress on the member 11 increases until it reaches a value at which the nose portion 14 moves into the next adjacent depression, whereafter further turns are wound into said next depression and so on. The result is a tendancy to produce a smooth surfaced package. The axial displacement of the end of the member 11 is preferably achieved as a result of resilience of the member itself but it is also possible for the member to be rigid and the displacement to be achieved by permitting elastic yielding of the support for the member 11. Fig. 1 shows the invention applied to a flyer 4 rotating around an axially moving package. The traversing member 11 is a snapon fit on a spindle carried by the flyer 4 and a coiled spring 22 rotates the member 11 about the spindle and into engagement with the package 1.
