Title: Bag Holding Mechanism for Bagging Machine
Inventor: TROYER ABNER J
IPC: B65B43/54
Filed: 1968-03-11
Abstract: 1,174,527. Bagging machine; discharging articles. TROYER MFG. CO. 11 March, 1968 [15 Feb., 1968], No. 11812/68. Headings B8C and B8S. [Also in Division G1] In a rotary bagging machine, feed shoots have pivoted arms to grip bags against the shoot walls and release them in a power-assisted manner, the power means having a neutral position at which the arms are influenced by gravity only so that they are readily moved clear during fitting of the empty bags to the shoots and then fall back to grip them lightly. Articles to be weighed and bagged pass through openings 14 in a rotating wall 11, which forms a hopper with an oppositely rotating cone 10. These openings are controlled by gates 16 and their upper portions are closed by springs 15 permitting visual inspection of the hopper contents level. When the gates are open the articles enter adjustable width discharge shoots 17. These shoots are mounted on balance arms 28 to operate the weighing scale 29. Bags are gripped against the shoot walls by pivoted arms 44, two to each shoot, which are each powered by double acting piston and cylinder means 61, 62 acting through a lost motion connection including a link 54. The cylinder 62 has a spring 66 to hold the piston in a neutral position so that the arms can be manually raised to place the bags on the shoot and then drop so that the weight of the arms hold the bag. Just prior to commencement of filling, the piston 61 is moved upwards to cause the link 54 to engage the arm 44 so that the latter grips the bag simultaneously with the respective gate 16 being opened. When the bags contain a predetermined weighed amount, the gate 16 is automatically closed and the piston 61 operates in the reverse sense to release the bag.

Abstract: 1,137,471. Pressing and rolling glass. S. M. COX. 21 June, 1966 [22 March, 1965], No. 11986/65. Heading G1M. An element of glass or glazed ceramic is given a smooth surface on at least one face by pressure thereon of a component having a working face itself of optical smoothness. Heated glazed ceramic is given a smooth surface by rolling thereover a roller and a glass gob is pressed by a die 14, the die or roller having an optically smooth surface and being preferably of fused silica glass coated with a film of refractory oxide, e.g. of tin, titanium or aluminium. As shown, a glass disc is formed by upward pressure of a mould 12 against the die 14, the gob of glass being produced from a glass rod 1 held in a rotatable chuck 2 mounted in a vertically displaceable member 4 connected to a counterweight, a clutch 5 to a pulley 3 being operable to move the member 4 up or down under the control of an optical system 6. The optical system 6 comprises two photo-sensitive cells at vertically spaced points, to sense a suspended gob of glass melted from the lower end of glass rod 1 by an oxy-gas torch 7 carried by a horizontal slide 8. The automatic movements control the size and temperature of the gob which falls rapidly under gravity from the rod 1 on to a shoot 11 directly in to the mould 12. The mould operation includes a trip switch on closure of mould 12 and die 14 to determine the time of dwell.

Title: Improvements in or relating to fuels for high compression ignition engines
IPC: C10L1/196
Filed: 1944-06-30
Abstract: 573,364. Fuel oils. ARNOLD, J. C. (Standard Oil Development Co.) June 30, 1944, No. 12472. [Class 91] The cloud point of compression-ignition fuels, e.g., Diesel oil, is lowered by the addition of 1-20 per cent. of soluble polyacrylic esters, enabling high-ignition value fuels to be used at low temperatures without causing clogging of the fuel line filters, and without lowering the cetane value of the fuels. These polymers, or co-polymers, are obtained by known processes from acrylic esters having the general formula CH2=C(X)-COOR. where R is a substituted or unsubstituted aliphatic, aromatic or hydroaromatic group, preferably containing at least 10 carbon atoms of which preferably at least 4 are aliphatic, and where X is hydrogen, halogen, or a methyl or ethyl radicle. Preferred esters are of the type where X is a methyl radicle, and R is a monohydroxy aliphatic alcohol having 4-12 carbon atoms, e.g., lauryl methacrylate. The soluble polymers produced normally have Mol. Wts. in the range 7,000-15,000. The invention is applicable to low pour point base stocks, e.g., hydrogenated naphthenic gas oils or raffinates from solvent extraction &c. which generally have cloud points considerably higher than their pour points. It is of particular advantage for use with base stocks having a cloud point above 0‹F., or paraffinic Diesel fuel base stocks normally having a cloud point above -10‹F. Sufficient esters may be used to reduce the cloud point to below -40‹F. It is stated that these polyacrylic esters have been used to lower the pour point of lubricating oils.

Abstract: 623,175. Valve amplifying & pulse circuits. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. June 30, 1944, No. 12480. [Class 40 (vi)] In a broad-band amplifier, in which signals are applied to an input filter, the grids of a number of valves are connected to points on the filter, the output electrodes of the valves being connected to separate filters having the same pass-band. A connection is made between points on the output filters which give the same delay relative to the input signal. The output filters may be combined into a single tapered filter. Signals from the valve V1, Fig. 7, are applied to the input filter consisting of inductors L and stray and valve electrode capacities C, valves V2, V3, V4 being fed from appropriate tapping points in the filter. Similar filters are connected in the anode leads of the valves so that points P2, P3, P4 giving the total delay may be connected in parallel to an output terminal. In a modification, Fig. 8 (not shown), the three output filters are replaced by a common tapered filter, and in a further modification, Fig. 9 (not shown), the valves may be connected as cathode followers. The filters may be constructed of lengths of concentric cable, Fig. 12 (not shown). By shortcircuiting the tapered output filter, Fig. 13 (not shown), a pulse may be derived from a rectangular input waveform of duration determined by the sections between the output terminal in the line and the shorted end.
