Title: An improved machine for setting-up cartons
Inventor: OXBORROW BERNARD HEWLETT
IPC: B31B3/44
Filed: 1959-08-13
Abstract: 887,495. Making cartons. METAL BOX CO. Ltd. July 19, 1960 [Aug. 13, 1959], No. 27762/59. Class 18. A carton as shown in Fig. 2 is formed by applying heat and pressure to side-forming portions of a blank after it is set up, the blank having been pre-coated with a heat-sealable material ; and the machine which effects the operation comprises dies and punches supported for simultaneous movement in one direction. The blank is removed from a magazine 14, Fig. 5, by sucker elements 15 which are connected to a source of negative air pressure and are rocked about a shaft 17 through camoperated linkage, the drive being provided by an electric motor 27, Fig. 6. From a waiting station formed by a support 28 the blank is transferred by fingers 29 on a reciprocating carriage 30 to a position over one of four dies D moving in a circular path about a pillar 41 and having projections which carry the blank with the die as it rotates. The dies are secured on a carrier 40 rotated through gearing 42 driven from a gear-box 26, and each die comprises four walls, opposite walls 44, 45 embodying heater devices 46, Fig. 7. A switch 53 movable with each die is operated by a stationary cam 54 to provide current for the heaters. Also movable with each die is a punch 56 on a carrier 57 slidable axially of a guide 58 in order to set up the blank in the die. A roller 61 on the carrier 57 runs in a cam track 60 under control of a stationary cam 59 secured to the pillar 41. The punch 56 slides on pins 62 against the action of springs 63 and has pads 64 which apply pressure to the carton sides when the pads are urged outwards by a wedge 66. The carton is ejected from the die by a spring-loaded pad 68. A stripper 72 disengages the carton from the punch, and a guide 73, Fig. 3, takes it off to a channel 74 along which it is pushed by a member 75. The sequence of operations shown in Fig. 3 includes a setting up phase 77, a phase 78 during which the heater devices are effective, a cooling phase 79, and an ejection phase 80. The inner surface of the blank may be precoated with a thermoplastic, e.g. polyethylene ; or its opposite sides may be coated with paraffin wax, the areas which are to be adhered having a coating of thermoplastic adhesive under the wax. In a modification the heater devices are fitted to the punch 56 and the pressure pads provided in-the die walls. The outline form of a blank, before it is set up, is shown at the position 76 in Fig. 3.

Title: Process and apparatus for the determination of the amount of carbonic acid contained in flue gases by the thermal conductivity method
IPC: G01N27/18
Filed: 1927-10-20
Abstract: 279,478. Siemens & Halske Akt.-Ges. Oct. 25, 1926, [Convention date]. Gas analysis.-Relates to the process of testing flue gases by measuring the resistance of an electrically heated wire, past which they flow, a comparison wire in a current of air being also employed. It is stated that the reading of a bridge galvanometer employed in such a method varies with the voltage of the heating current, the rate of variation being proportional to the heating current when the wire is at 200 C. The test is therefore carried out at this temperature by means of the apparatus shown in the figure, the testing wires g, hand comparison wires n, o being enclosed in chambers through which flue gas and air pass respectively. The current is supplied from a transformer u which is connected to the test wires and the coil of a moving-coil galvanometer p as shown, and also to the field coils t of the galvanometer. The galvanometer is of the type fitted with a second moving coil short-circuited through a condenser. The Specification as open to inspection under Sect. 91 (3) (a), states that the variation of the galvanometer reading with the voltage is practically nil at 335, and that the tests may be carried out at this temperature with an ordinary galvanometer. This subject-matter does not appear in the Specification as accepted.

Patent GB-654032-A (GB)
Title: Improvements in or relating to the purification of vinyl ethers
Filed: 1948-10-29
Abstract: Vinyl ethers which have been obtained by vinylating an alcohol of the C4-C8 range with acetylene are purified by a process which comprises the step of reducing the residual alcohol content of the substantially azeotropic mixture of vinyl ether and the corresponding alcohol obtained on distillation of the crude vinylation product by boiling the said mixture with an alkali metal hydroxide so as to convert the alcohol to its metal alkoxide while continuously removing the water simultaneously formed from the reaction zone by entrainment with the vinyl ether itself, condensing the mixed vinyl ether/water vapours so as to separate the condensate into two layers, continuously returning the upper layer to the reaction zone and subsequently separating the vinyl ether from the alkoxide formed. The alcohol content of the initial azeotrope together with any vinyl ether remaining in the reaction vessel may be recovered by adding water to the alkoxide and distilling the mixture when the distillate consists of a lower aqueous layer and an upper layer comprising a mixture of alcohol and the residual vinyl ether.  Distillation of this upper layer yields pure alcohol and the vinyl ether as its azeotrope with the alcohol.  An alternative method of recovering the alcohol content is to add water to the alkoxide, removing the solution, separating into two layers and isolating the upper layer comprising a mixture of vinyl ether and alcohol.  The amount of the alkali metal hydroxide used in the process may be from 25 to 200 per cent and preferably 33 to 50 per cent of that which is chemically equivalent to the amount of alcohol present in the azeotrope.  In examples: (1), (2) and (3) an azeotropic mixture of isoamyl vinyl ether and isoamyl alcohol which has been prepared by reacting acetylene with isoamyl alcohol in the presence of caustic potash at 150-165 DEG  C. and then distilling to separate the azeotrope from excess alcohol is treated with sodium hydroxide and then boiled under reflux in a still with a fractionating column. The distillate is run into a separator and the top liquid layer returned to the still, the distillation being continued until the water has separated out.  The vinyl ether is collected by further distillation.  Water is added to the residue in the still base and further distillation yields two layers, a portion of the aqueous layer being returned to the still until no more organic material distils over; (4) an azeotropic mixture of 2-ethylbutyl vinyl ether prepared by reacting the alcohol with acetylene as in (1) is treated with caustic soda as in (1); (5) a mixture of n-hexyl vinyl ether and n-hexyl alcohol prepared as in (1) from the alcohol and acetylene are treated with potassium hydroxide as in (1) to recover the vinyl ether.

Title: Milling cutters for helical or spiral and straight bevel gears
IPC: B23F21/16
Filed: 1924-01-22
Abstract: 214,738. Wheatley, W. H. Jan. 22, 1924. Gear-cutting; milling-cutters.- Straight or spiral bevel gears are cut in a single continuous operation by means of a rotary cutter having a series of cutting-teeth arranged on a helical path and adapted to co-operate in pairs, each pair being shaped to cut the opposite sides of the groove between a pair of teeth at a particular point in the length of the groove. In order to avoid interference the teeth are arranged on approximately two-thirds of one convolution as shown in Fig. 1. A series of eight equally spaced teeth work in pairs 1 - - 4, each tooth having a cutting-edge on one side only, the cutting-edges of any pair of teeth being on opposite sides of the centre line. In cutting a bevel wheel the cutting-edges of the central pair 4 approximately fit the tooth space of the blank at the section A, Fig. 4, while the cutting-edges of the pairs 3, 2, 1, approximately fit the tooth space of the blank at the sections B, C, D respectively. The helical pitch of the teeth of the cutter is preferably equal to the pitch of the blank teeth at the small end. In making the cutter, the cutting-edges a of the teeth 3, Fig. 5, are formed slightly nearer to the central helix x, y in order that they may not contact with that portion of the groove cut by the teeth 4. The teeth 2 are similarly set back from the teeth 3 and so on. The non-cutting edges b and the back portions of the teeth are backed off. To obtain correct shape of the cutting-edges of the teeth, full size sections of a tooth of the wheel at the lines A, B, C, D are drawn and from these drawings templets to which the cutting- edges may be fitted are prepared. In operation the blank is continuously rotated so that during one revolution of the cutter the blank rotates through one pitch and the teeth are completed by feeding the cutter once across the blank. Alternatively the blank may be fed across the cutter. For cutting spiral bevels the blank and cutter axes are suitably inclined.
