Title: Apparatus for expelling air from a bagged product
IPC: B65B31/00
Filed: 1971-06-25
Abstract: 1350838 Expelling air from bagged products UNION CARBIDE CORP 25 June 1971 [26 June 1970] 30011/71 Heading B8C Air is expelled from a plastics bag containing meat by partially immersing the bag in water. While the bag is immersed, its open end is gathered and sealed. A bag to be immersed is transferred from a rollerway 26 onto a stationary endless conveyer 21 located above a water tank 11. The open end of the bag is pushed over a spring loaded gate 51 of a bag closing device 41 to be retained in an opening 30. The bag is clamped onto the conveyer 21 by discs 34 which are mounted on slack cables 34 and which are forced against the bag by piston and cylinder units 40. The conveyer 21 and the bag retaining devices are pivoted downwards about an axis 42 to immerse the bag, apart from its open end, in the tank 11. After expulsion of air, but while the bag is still immersed, a plate 52 is pivoted to gather the open end of the bag prior to the application of a sealing staple. The staple may be applied below the water level. The conveyer 21 is returned to the horizontal and motivated to move the closed bag to an output conveyer 47. Two air expelling devices may be served by single input and output conveyers, Fig. 7 (not shown).

Title: Improved triazine-aldehyde compounds and fuel oil compositions containing the same
IPC: C10L1/22
Filed: 1956-10-02
Abstract: The invention comprises compounds of the formula <FORM:0797182/IV (b)/1> where R is a C8-C22 aliphatic hydrocarbon radical and R1 and R11 are H or C1-C4 alkyl.  The residue R may be saturated or unsaturated and may be a mixture derived from an animal or vegetable oil.  These are made by reacting together a diamine R-NH-CH2CH2CH2NH2, formaldehyde (or polymer thereof) and an aldehyde CHR1R11-CHO in the proportions 1 : 2 : 1.  Examples show the use of isobutyraldehyde (R1=R11=methyl) and various amines where R is derived from coco and tallow acids.  The corresponding compounds in which R is dodecyl or the soya residue are also mentioned.ALSO:Fuel oil compositions contain a triazine derivative of the formula <FORM:0797182/III/1> where R is a C8-C22 aliphatic hydrocarbon radical and R1 and R11 are H or C1-C4 alkyl.  The residue R may be saturated or unsaturated and may be a mixture derived from an animal or vegetable oil, e.g. coco, soya or tallow; R1 and R11 are preferably methyl.  The compounds may be added to the extent of 50-100 parts per million to cracked gas oils, domestic fuel oils, furnace oils, burner oils, Diesel oils, kerosene and other hydrocarbon distillate fuel oils; smaller or larger amounts are however possible.

A hexagonal table can be formed from six such nestable tables, Fig. 1 (not shown), or from three nestable tables 10 and three laminar members 30 of the same dimensions, Fig. 5. The table tops 11 and laminar members 30 are joined by tongue in slot arrangements 31, each comprising a tapered slot (32), Figs. 6 and 8 (not shown) in the top 11 (or in the member 30) that receives a tapered tongue 34, Figs. 7 and (9) in the member 30 (or in the top 11). Tongue 34 slides in a slot 33 of member 30 and has a stop peg 35 slideable in an upper slot 36 of slot 33.

Title: Tow line vehicle accumulator
IPC: B61B10/04
Filed: 1976-07-20
Abstract: 1509657 Accumulator for tow line vehicles SI HANDLING SYSTEMS Inc 20 July 1976 [21 July 1975] 30068/76 Heading B7L In a tow line vehicle accumulator, a conveyer chain 48 runs in a track 42, 46 so that a tow pin 40 of a vehicle is guided by a conveyer dog 52 in a slot 38 provided between edges of top walls 22 and 24, 26 of a housing 12, and control members 54, 70 are respectively pivoted at 56, 72 and are urged by springs 62, 80 or other biasing means towards the tow pin. When a latch lever 88 is moved by a slolenoid 100 out of engagement with the control member 70, a tow pin 40 moving along the slot 38 pivots the member 70 against the action of the spring 80, which is weaker than the spring 60, so that the pin can move along the slot without being stopped. If the latch secures the member 70 against movement, the tow pin pivots the member 54 counterclockwise so that the pin moves into a widened portion 32, 34 of the slot 38 and hence disengages from the conveyer dog 52 so that the vehicle comes to a halt. Switches 106, 110 which control the action of the solenoid 100 may be operated by the tow pin.

Title: Electric switches

Filed: 1972-06-27
Abstract: 1371123 Thermal switches MICRO DEVICES CORP 27 June 1972 [16 July 1971] 30116/72 Heading H1N A thermal cut-out is identical to the one described with reference to Figs. 1-5 of U.K. Specification 1,255,589, except that the identical reduced diameter end portions 36, 38 of the insulating plug 16 closing one end of the conductive casing 12 are at least as long as the enlarged diameter central portion 32. Because the plug 16 is symmetrical about a central axis transverse to its length probelms of incorrect orientation of the plug do not arise when it is automatically assembled in the casing 12. The greater axial length of end portion 36 ensures that the length of plug insulation between the casing end flange 44 and the exposed outer end of conductor 20 is greater than in U.K. Specification 1,255,589. As the overall length of the plug 16 is the same as that of the aforementioned U.K. Specification the length of the central portion 32 is reduced and hence the length of the counterbore 34 in casing 12 is reduced. Each end portion 36, 38 has two frusto-conical parts 35, 37 between which an annular seat 139 for biasing spring 54 is formed. In Figs. 8 and 9 (not shown) each end portion 36, 38 has a single smooth frustoconical surface.

Abstract: 1,001,565. Donning and doffing apparatus. DEERING MILLIKEN RESEARCH CORPORATION. Aug. 22, 1961 [Aug. 22, 1960], No. 30273/61. Addition to 990, 542. Heading DiD. The doffing and donning carriers of the parent Specification are suspended from a sub-carriage itself carried by a horizontally-movable support carriage so as to be movable relatively to the support carriage. In Fig. 2, the first carrier is a channel beam 51b with empty-bobbin holders 51a, and the other is a similar beam 53b with package holders 53a. The holders are as described in Specification 902,972 and correspond in number to the spindles to be doffed together on one side of a spinning frame. The carriers can be raised and lowered independently by cables 67, 77 from a subcarriage 81 running on rails 85 on a support carriage 29 which in turn can run on rails 31, Fig. 1, on a main carriage 27 which can run on rails 25, motors 47, 39 controlling the movements of the support and main carriages. Thus, with doublerow spinning frames arranged parallel to one another in rows as at 11, the carriers can be brought above any desired row of spindles. The cables 67, 77 pass over pulleys 69a, 79a on the sub-frame and pulleys 69, 79 on the support carriage to capstans 65, 75 driven from motors 61, 71. After the doffing holders have engaged the spindles, it is necessary to raise them and move the carriers outwardly from the centre line of the supportcarriage so that the donning-holders are above the spindles. Accordingly the sub-carriage 81 is attached by cables 93 to the piston of a hydraulic cylinder 91 controlled by a valve V, the sub-carriage being biased towards the inner position by the weight of the holders. A second set of holders is carried on the other side of the support carriage from the set shown.
