Title: Delivering means for use on paper bag making machines
IPC: B65H29/14
Filed: 1930-03-12
Abstract: 343,345. Delivery apparatus for paper - bag making machines. WINDMOLLER & HÍLSCHER GES. and DAMBACHER, X., 27, Munsterstrasse, both in Lengerich, Westphalia, Germany. March 12, 1930, No. 7994. [Class 100 (i).] The delivery means of a paper-bag-making machine, in which the bags are conveyed in flakelike formation on a conveyer belt to the delivery table, comprises a rotating gripper device which seizes the formed bags one by one and lays them bottom downwards on the belt, the bags being retained thereon by pressure bands as far as the delivery table, where they are thrown one on top of the other to form a stack. The cut bag tubes are fed between bands 2, 3 to the bottom forming cylinders 4, 5, the formed bottom being adjacent to the cylinders 4. The bag then descends between bands 6, 6a, being seized one by one by grippers 9 and delivered on to the conveying belt 10. The grippers, attached to spaced discs 8, are rotated at a greater linear speed than that of the belt 10, so that the bags assume a flake-like formation. Two bands 17<1>, of the pressure bands 17, are led over guide pulleys 18a, placed between the spaced discs 8, so that the bags are seized and pressed on to the belt 10 as soon as delivered by the grippers. The bags then move to the delivery point 14, 18f, where the belt 10 drops vertically, where they are thrown on to the delivery table. This latter consists of two ledges 15<1> attached to two vertical screwed stops 22, which are rotated in opposite directions by sprocket 29, shaft 26, and bevels 24, 25. Each vertical element is splined to the shaft 26, being capable of horizontal movement along the element 28<1>, and the whole stacking element may be slid horizontally along the frame so that the ledges 151 can accommodate different sized bags. As the screws are rotated, the bags in contact therewith are pressed downwardly to slope the pile away from the delivery point.

Title: Improvements in or relating to Machines for Making Bottles.
Inventor: WADE HAROLD
IPC: C03B9/325
Filed: 1918-05-13
Abstract: 126,782. Wade, H., (Lockwood, L. V.). May 13, 1918. Blowing.-Relates to mechanism for forming screw-threads in bottle-necks applied to a rotary machine in which a series of parison moulds are mounted on an intermittingly moving table, several bottles being in process of manufacture at the same time. The parison moulds are opened and closed by the usual cam mechanism and the blowing is effected in the customary manner. The moulds C each consist of two parts mounted on a vertical pivot carried by the table B and arranged to close on an upstanding part 5 of the mould bottom C' and shaped so as to enclose the end 7 of tongs which form the outer part of the neck. The screw-forming nipple 12 is carried by a spindle D, the lower end of which is threaded at 12a and works in a cross-bar 13<b> carried on pillars 13<a> extending downwards from a plate 13 fixed to the table B. The spindle D causes a pinion D', the vertical movement of which is limited by stops. As the mould approaches the charging station, the pinion D' engages a spur wheel F frictionally connected to a shaft 78 which is driven through bevel gearing G<3> by an electric motor. The spur wheel F, by rotating the spindle D, causes it to rise by the action of the thread 12<a> and the nipple enters the closed mould. After the mould has been charged and the molten metal forced down into the neck part of the mould by compressed air, the table moves forward and the pinion D' engages a spur wheel similar to F, but driven in the reverse direction which causes the nipple to be withdrawn. At the blowing station, air is admitted through a lateral port to the space 11<a> and the preliminary blowing is effected. The mould is automatically opened and the parison is removed in the tongs for finishing in the usual way.

Title: Improvements in or relating to electric interrupter switches
IPC: H01H37/50
Filed: 1951-04-06
Abstract: 711,348. Thermal switches; snap-action switches. MIDGLEY, A. H., and MIDGLEY, A. M. April 7, 1952 [April 6, 1951; April 26, 1951], Nos. 8056/51 and 9735/51. Class 38(5) A. thermal "flasher" or switch has a sheet 5 of spring material with two longitudinal slots 5b forming a centrally disposed strip 5c, the length of which is increased slightly in relation to the side strips, and the central and side strips being bowed in the same direction. A tensioned wire 10 maintains the sheet 5 bowed in the reverse direction against its natural bias, so that a contact 5d on the central strip abuts an adjustable stop screw 8. On the heating of the wire 10 so that it relaxes its tension, the sheet 5 returns to its natural bowed position, the central strip 5c moving the contact 5d with a snap-action into engagement with a fixed contact 3b. The wire 10 is now short-circuited and cools, reversing the curvature of the sheet to re-open the contacts, the cycle being repeated. In a modification, Fig. 3 (not shown), the top of the sheet 5 is loosely held in spaced relation to a terminal extension piece (as 2a in Fig. 1) by means of an insulating sheet. Alternatively, the side strips may be rigidly supported about a line transverse of the sheet adjacent the ends of the slots, the side strips being gripped between inturned portions of the extension piece (as 2a) and extended insulating strips interposed between the side strips and the fixed contact-carrying member, Figs. 4 and 5 (not shown).

[Class 38 (iv)] In means for the automatic regulation of the voltage of a D.C. generator comprising a thermionic discharge tube controlled by the voltage of the generator and controlling the generated voltage by the field excitation of the generator smoothing means are provided in the input or control circuit of the thermionic tube which smooth out the A.C. component in the generator voltage but limit the phase displacement of the control voltage so as to prevent positive retro-action of the regulating arrangement. The smoothing device may comprise two series resistances R1, R2 connected across the mains, resistance R2 being paralleled by a condenser K and connected between grid and cathode of the thermionic valve. Alternatively the condenser K may be in series with the resistances and the grid-cathode circuit of the valve may be connected across the resistance R2 and condenser K in series. An additional condenser may be connected in parallel with the resistance R1. In a further arrangement an inductance, which may be paralleled by a condenser, is connected in series with the condenser K, and resistances R1, R2, the grid-cathode of the valve being connected across the resistance R1 condenser K and inductance in series. The anode of the valve which may be coupled to the grid of a following valve may be connected to one of the mains through a resistance and condenser. All the resistances may be variable to provide a variable phase displacement, and the anodes of the valves may be supplied from the generator voltage or from a separate supply.

Patent GB-655886-A (GB)
Title: Production of polynitro-paraffins
Filed: 1948-03-18
Abstract: Polynitro-paraffins are made by reacting a mixture of a paraffin or cycloparaffin and a mononitro derivative thereof or a polynitro derivative thereof, having at least one nitro group less than the desired polynitro paraffin, with a nitrating agent at 150-250 DEG C., preferably 150-230 DEG  C., and above 200 pounds per square inch, the polynitro paraffin to be prepared and nitroparaffin used in the reaction having each at least 3 carbon atoms in the molecule, the nitro groups being attached to other than primary carbon atoms and one hydrogen atom of the nitroparaffin used is attached to other than a primary carbon atom.  Nitrating agent is defined as nitric acid and oxides of nitrogen higher than NO.  Nitric acid is preferred, concentrations of 40-70 per cent being instanced.  Sulphuric acid may be present in quantities insufficient to cause oxidation.  A primary carbon atom is defined as a carbon atom which is attached to only one other carbon atom.  Butane, pentanes, hexanes, neohexane, 2,3-dimethyl butane and cyclohexane are specified paraffins.  The process is of particular importance in the preparation of 2,2-dinitro-propane from propane and 2-nitro-propane.  The process may be made continuous by passing the reactants through a stainless steel tube and separating and recycling the starting nitroparaffin which is itself formed in the reaction together with additional paraffin and nitrating agent or all three reactants may be recycled. The reactor may be packed with inert materials.  It is preferred to have excess nitroparaffin and/or paraffin, ratios of 1/2 -1 mol. of nitric acid per mol. total of parent paraffin plus nitroparaffin being satisfactory.  Explosions are likely to occur as the proportion of nitric acid is increased and at above 250 DEG  C.  Ratio of parent paraffin to nitroparaffin is preferably adjusted to obtain a constant amount of starting nitroparaffin for recycling.  Ratios of paraffin to nitroparaffin instanced are 0.25-4.0 mols., preferably 0.5-2.0 mols., per mol. Diluents, e.g. water, nitrogen and carbon dioxide may be present, water in proportions of 10-80 mol. per cent of total reactants. Pressures instanced are 200-2500, preferably 800-1200, pounds per square inch.  Space velocities in excess of 0.1 may be used, preferably 0.5-2.5.  In an example, propane mixed with 2-nitropropane and water is treated with 70 per cent nitric acid at 204 DEG  C. and 900 pounds per square inch, unchanged 2-nitropropane being recycled, and results are compared with those obtained with two prior processes, in which 2 nitropropane and propane are separately treated under the same conditions.

Filed: 1922-03-21
Abstract: 199,778. Brougham, F. J., (Harris Record & Phonograph Co., Ltd.). March 21, 1922. Records, materials for. - Record blanks are made of paper or similar fibrous material combined with glue, dextrin 'and shellac. The sound grooves may be impressed directly in a disc of this composition, or, in making a product of better quality, a coating of the usual material for taking the impressions is provided, the coating material being applied as a powder and caused to adhere to the body portion by heating. Solutions of each of the three ingredients are prepared and may be mixed together to form a bath in which sheets of paper or the like are soaked, or separate solutions of glue, dextrin, and shellac are made, with which the paper &c. is treated successively. An alternative method consists in mixing fibre or pulp with a composition of the three ingredients moulding the resultant paste into discs and drying. In either case a spongy product is obtained which can be compressed, preferably whilst heating, into a hard mass. The solutions may be prepared as follows. Shellac is dissolved by heating in an alkaline solution, such as borax and water, and a solution of fish glue in water (or other glue dissolved in weak acetic acid) is added. Dextrin dissolved in water containing borax and sugar is then added to the previously prepared mixture. The preferred proportions of the ingredients are specified.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/42
Filed: 1926-03-26
Abstract: 273,015. Automatic Telephone Manufacturing Co., Ltd.., and Mercer R. March 26, 1926. Automatic exchange systems.-In a network in which two exchange letters only are required to differentiate between all the exchanges, subscribers or operators set up three letters, but one, preierably the second, is suppressed, or routed away from the normal receiving apparatus. In calls from substations the suppression is preferably effected at the register translator, but in the case of operators' impulse senders with a row of keys for each letter, the row corresponding to the letter to be suppressed is left dead, or in a sender of the kind described in Specification 220,774, one of the keypressing operations is rendered ineffective. In systems comprising four and three letter networks, the second letter at three digit exchanges may be suppressed at the A digit switch and used to energize the switching relay. Fig. 1 shows a sequence switch S for steering the incoming digits to the registers of a register translator of the usual kind, provided with means whereby by a simple manual operation it may be adapted either to receive and record two exchange letters or to receive three and record only the first and third. In the first case a stop AM is so adjusted that the normal position of the wipers 106, 107 of the switch S is on the second contact set, the first set being ineffective, whilst terminals 5, 1 and 6, 3 of a terminal block TB are jumpered so that the first and second digits are directed over conductors 121, 122 respectively to the vertical and rotary magnets of the exchange register. In the second case the stop AM is adjusted to make the first contact set the normal position, and terminals 1, 4 and 2, 5 and 3, 6 of the block TB are jumpered so that the first and third digits are directed to the exchange register and the second digit is routed away over a resistance 7. In a modification in which the switch S is a continuous motion one with an additional restoring wiper, the first four contacts engaged by this wiper are connected to extra terminals provided on the block TB, and the jumpering between these terminals may be modified to cause the switch to restore to its first or second position. Specifications 194,580, 220,923 and 233,007 also are referred to.
