Title: Sequence timer for resistance welding machine
IPC: B23K11/24
Filed: 1962-07-04
Abstract: 1,001,651. Resistance welders. ROBOTRON CORPORATION. July 4, 1962 [Aug. 14, 1961], No. 26707/62. Heading H2H. A sequence timing circuit for controlling the hold squeeze and weld times of a resistance welder comprises A.C. bus lines 13, 16, supplying a first valve 26 which is rendered conductive when a starting switch 17 is closed, energizing a relay 19, 21, the conduction energizing another relay 28 held by contacts 41, which relay closes the welding electrodes through an hydraulic circuit (not shown). A phase-shift circuit comprising a secondary winding 34, resistor 38 and a capacitor 39 blocks the tube 26 a short time after. Closure of contacts 21, 41 also supply through a conductor 43 a rectifier 112 and resistors 116, 118, 121 which charge a capcitor 127 which applies a negative voltage to control electrode 104 of a previously conducting valve 91 thereby blocking it, hence a capacitor 101 in the anode circuit discharges through a shunting resistor 97, which discharge determines the squeeze time and causes a valve 131 to conduct, energizing a transformer 134 whose secondary circuit is completed through the transformer 149 and conductive valve 146. Conduction of valve 131 also removes the potential through a rectifier 172 of a capacitor 187 which discharges through a rheostat 184 determining the weld time. The secondary winding of transformer 149 through a rectifier 201 charges a capacitor 208 positively which through a CR combination 210, 212, overcomes the negative bias of another capacitor 234 and fires a valve 221. Adjustment of the values of the CR combination determines the cycle point at which valve 221 conducts, which (a) energizes a transformer 268 overcoming the negative bias on capacitors 276, 277 and renders the ignitrons 273 conductive and (b) positively charges a capacitor 263 through a rectifier 266 and resistors 264, 253 which renders a reverse parallel connected valve 236 conductive by overcoming the negative potential of a capacitor 265. When capacitor 187 has discharged through rheostat 184, valve 146 blocks de-energizing transformers 82, 149, hence (a) a capacitor 208 will discharge through a resistor 207 and valve 221 will block at the next negative half-cycle zero and (b) a capacitor 89 discharges through a resistor 86 and valve 26 blocks, thus de-energizing relay 29 which opens contacts 41 and permits the welding electrodes to open. Until switch 17 is opened, the feed is maintained to the rectifier 112 holding valve 91 non - conductive. For repetitive operation, switches 113, 125 are opened, hence the feed to rectifier 112 is broken and the circuit will cycle as long as switch 17 is closed. When switch 17 is opened, contacts 21 also open the cathode potential will be removed when relay 28, 41 is de-energized at the end of a cycle, thus preventing further operation until switch 17 is again closed.
Patent GB-257632-A (GB)
Abstract: 257,632. British Thomson-Houston Co., Ltd., (Assignees of Goff, R. W.). Aug. 31, 1925, [Convention date]. Electrically - released switches; electromagnetic switches.-An electromagnet 13 attracting an armature 14 from the position of Fig. 1 acts through a connecting link 18, a pin 19, and a slot 25 to rock a cam 16 fast on a spindle 11 which carries the contactors, switches, or other devices to be operated. After operation, the cam is retained against the pull of a throw-off spring 22 by a spring-controlled latching member 20, thus allowing the electromagnet to release the armature without disturbing the result of the operation, the parts then taking the positions of Fig. 2. When the electromagnet again attracts the armature the pin 19 acts on a loose cam 17 which releases the latch and allows the fast cam 16, the spindle 11 and the devices carried thereon to return to their original positions as shown in Fig. 3. When the invention is used for switching on and off an electric motor by push-button control, auxiliary contacts 30, 31 alternately deenergize the magnet after each attraction, the magnet having two windings 32, 33 connected to a two-way push-button 34.

Abstract: 381,314. Refrigerating. FRIGIDAIRE CORPORATION, 3rd National Building, Dayton, Ohio, U.S.A.-(Assignees of Smith, H. F.; Rural Route, 11, Dayton, Ohio, U.S.A.) Sept. 14, 1931, No. 25767. Convention date, Sept. 29, 1930. [Class 29.] Absorption machines and systems.-Refrigerating apparatus comprises two or more generator absorbers operating intermittently to produce substantially continuous refrigeration, the heat of absorption from the first generator absorber forming the sole supply of heat for generation in the second. Generator absorber c<20> contains an absorbent which liberates refrigerant at a lower temperature than that in which the absorbent in generator absorber c<10> absorbs refrigerant. Thus by arranging for heat exchange between the absorbers, either by a closed circuit comprising jackets c<17>, c<25> and pipes c<29>, c', or by a straight through flow of fluid through jacket c<17> to jacket c<25> and then to waste, absorption takes place in generator absorber c<10> and generation in generator absorber c<20> without external supply of heat. For the remaining half of the cycle, generator absorber c<10> generates under the influence of electric heater c<16> and generator absorber c<20> absorbs under the influence of cooling coil c<42>. Examples of refrigerants operating at suitable temperatures are given. By causing the evaporators c<14>, c<24> of the two systems to cool spaces 63, 60 connected to a third evaporator 62 containing a volatile liquid, practically continuous refrigeration is obtained in the third evaporator.

Title: Colouring cellulose triacetate textile materials
Inventor: MANN RALPH JAMES
IPC: D06P1/92
Filed: 1956-08-23
Abstract: The cellulose triacetate content of textile materials consisting of or containing fibres thereof is coloured by contacting the material for from 5 to 120 seconds with a solution of an acid wool dye or a metallized azo or azomethine dye in an aqueous liquid containing per litre 100-250 grams of lower fatty alcohol, 300-500 grams of lower fatty acid, and 2-8 grams of sulphuric acid, and thereafter washing the material with water. By "lower fatty alcohol" is meant methyl, ethyl or n- or iso-propyl alcohol, and by "lower fatty acid" is meant formic or acetic acid.  In a modification of the process a part or the whole of the alcohol content of the dye solution is replaced by an equal weight of acetone.  The aqueous liquid may contain formic acid to the extent of at least 300 grams per litre, and preferably contains per litre 120-160 grams of the lower fatty alcohol, 350-450 grams of the lower fatty acid, of which at least 300 grams is formic acid, and 2-6 grams of sulphuric acid.  Fabrics may be passed continuously through a succession of baths of the dye solution with intervening passes through air, the baths being continuously replenished by feeding dye solution to the last bath and permitting each of the preceding baths to receive dye solution by overflow from the next succeeding bath.  Preferred metallized dyes include products obtained by metallizing, with one atomic proportion of chromium or cobalt, two molecular proportions of an unsulphonated monoazo dye in which the azo group unites two carbon atoms each of which is directly attached to a carbon atom carrying a hydroxyl group.  The aqueous liquid may also contain a wetting agent, e.g. the sodium salt of isopropyl naphthalene sulphonic acid, or "Teepol" 530 (Registered Trade Mark).  Specifications 448,817, 448,917, 500,960, 687,414, 719,853, 721,674, 726,900, 731,930, 748,772, 758,442, 859,685 and 863,207 are referred to.

Title: Improvements in apparatus for feeding "count" indicating slips
IPC: B65H33/04
Filed: 1944-03-15
Abstract: 608,025. Delivering sheets in counted batches. SOAG MACHINE TOOLS, Ltd., (trading as SOAG MACHINERY CO.), and EDLER, O. March 15, 1944, No. 25813/46. [Class 100(i)] A device for inserting count-indicating slips in a stack of sheets comprises an electrically-operated slip-feeding and severing means which, when started, is held in operation by a maintaining switch until a predetermined length of material has been fed. Every time a sheet-feeding mechanism completes a given number of operations, means, e.g. the counter described in Specification 607,951, [Group XIX], transmit an impulse to an electromagnet 42 which rocks an armature 43 about a pivot 44 to cause a pawl 45 to advance a ratchet wheel 46 fixed to a roller 47 co-operating with a second roller 48 to feed the slip 49. The first step of the ratchet wheel 46 causes a cam 53 thereon to diminish the distance between contacts 55, 56. A pin 61 on the armature 43 rocks a block 58 to close the contacts 55, 56 when the initial impulse ceases whereby the circuit of the magnet 42 is again completed and a further step given to the ratchet wheel 46. This stepping motion continues until the ratchet wheel completes one rotation and the cam 53 allows the contact 55 to move out of the range of the contact 56. Another cam 63 lifts and drops a blade 50 to sever the strip. In a modification, Fig. 5, the initiating impulse arriving at an electromagnet 79 rocks a lever 77, 74 to close contacts 78 in the circuit of a motor driving a feed roller 70 and a disc 72. A pin 73 on the lever 77, 74 is thus lifted from a recess in the disc 72, the lever being held rocked to maintain the contacts 78 closed until the feed roller has completed one revolution. A severing blade 80 is carried by the lever 77, 74.

Abstract: 1,271,545. Treating seeds to increase germination speed. R. D. AMBURN. 21 May, 1969 [27 June, 1968], No. 25830/69. Heading A2Q. The germination speed of seeds is increased by moving the seeds in a helical path through a magnetic field, or other field produced by a source of electric, magnetic or electromagnetic energy. As shown, a screw conveyer 20 conveys the seeds from an inlet chamber 16, which is supplied by a hopper 10 via a control slide 14, to an outlet chamber 24, the seeds being caused by the centrifugal force to move in a helical path along the inside wall of a plastic tube 22 past an electromagnet 38 surrounding the tube, so as to be subjected to a magnetic field while the seed is both moved in a helical path and is at the same time rolled to expose several surfaces of the seed to the field. The treated seeds are collected in a collector 26. The electromagnet 38 may be replaced by electric field generating means, or by X-ray, high frequency, microwave or other electromagnetic field generating means.

Patent GB-595459-A (GB)
Title: Improvements in or relating to the preparation of olefinic alcohols from the corresponding acetylenic alcohols
IPC: C07C33/025
Filed: 1944-12-27
Abstract: In a process for the production of olefinic alcohols by hydrogenating the corresponding acetylenic alcohols in the liquid phase in the presence of a palladium charcoal or sulphur-poisoned nickel catalyst (see Group IV) the acetylenic alcohol is preferably hydrogenated in aqueous solution and the olefinic alcohol removed from the reaction vessel by distillation of its constant boiling mixture with water. Any saturated alcohol produced also forms a constant boiling mixture with water and this boils at or slightly above the constant boiling mixture of olefinic alcohol and water.  The olefinic alcohol in the distillate, usually together with a small amount of saturated alcohol may be dried by azeotropic distillation with benzine.  The sulphur-poisoned nickel catalyst employed is prepared by boiling an aqueous mixture consisting of a small quantity of sodium sulphide and a nickel hydrogenation catalyst, e.g., Raney nickel.ALSO:Olefinic alcohols are prepared from the corresponding acetylenic alcohols by hydrogenating the latter in the liquid phase in the presence of a palladium charcoal or sulphur-poisoned nickel catalyst (see Group III).  The temperature employed is preferably 0 DEG  to 125 DEG  C. and the pressure may range from about 15 to 500 pounds per square inch, or higher.  The process may be carried out by effecting the hydrogenation in the presence of water, distilling off the olefinic alcohol as an azeotrope with water and returning the residue of water and catalyst to the hydrogenation chamber for further use.  In the examples, hydrogen under pressure is used to hydrogenate (1) 2-methyl-3-butyne-2-ol in the presence of water and a sulphur-poisoned nickel catalyst; (3) and (4) 2-methyl-3-butyne-2-ol in the presence of water and palladium charcoal; (2) and (5) 3 : 5-dimethyl - 1 - hexyne - 3 - ol and 2 : 5 - dimethyl - 3 - hexyne-2 : 5-diol respectively in the presence of methanol and palladium charcoal.  Other acetylenic alcohols which may be hydrogenated are stated to be 3-methyl-4-pentyne-3-ol, 2-phenyl-3-butyne-2-ol, 3-ethyl-4-pentyne-3 - ol, 3 : 6 - dimethyl - 4 - octyne - 3 : 6 - diol and 2 : 5 - diphenyl - 3 - hexyne - 2 : 5 - diol.  The 2-methyl-3-butene-2-ol produced by hydrogenation of 2-methyl-3-butyne-2-ol may be dehydrated to give isoprene.

Title: Improvements in and relating to the production of infants' food from cows' milk
IPC: A23C1/16
Filed: 1932-09-19
Abstract: In preparing a food for infants, which is dissolved or dispersed in water when required for use, by adding to evaporated milk a sugar with or without a fat, drying under vacuum, and finally granulating, when the product has been sufficiently dried it is cooled under vacuum and the vacuum is broken by admission of carbon dioxide or other inert gas soluble in water, after which the product is granulated and packed.  The dried and cooled product may be introduced into tins or like containers which are then subjected to vacuum and carbon dioxide or other water-soluble inert gas introduced and the container sealed.  The milk is preferably homogenized and after the addition of sugar, e.g. dextrose, maltose, or lactose, the product is sterilized by boiling at normal pressure in an atmosphere of carbon dioxide or other water-soluble inert gas, filtered, cooled, its pH-concentration adjusted, evaporated under vacuum to a moisture content of about 4 per cent, and the vacuum broken.  Vitamins may be added after the filtration when the product is at 15 DEG  C.  The pH value may be adjusted to 5,6, e.g. by addition of phosphates. The drying may be effected on stainless steel trays placed on hot-water heated shelves in a vacuum chamber, the temperature of the heating water not exceeding 55 DEG  C. the product is then cooled by passing cool water through the shelves.  To supply vitamin A, vitamin B complex, and vitamins C, D and E, there may be added respectively the unsaponifiable fraction of cod liver oil, the aqueous extract of yeast, the decitrated concentrate of lemon juice, vitamin calciferol, and wheat germ oil.  The oil-soluble vitamins may be dissolved in butter or other fat which is then emulsified in the milk.  The additions to the evaporated milk and their proportions may be adjusted to suit infants of different ages.

Filed: 1939-09-19
Abstract: 531,537. Honing or lapping. BURGESS, A. F. (Barnes Drill Co.). Sept. 19, 1939, No. 26138. [Class 60] A honing or lapping machine with a head 18, reciprocated horizontally on a guideway, from which projects a rotating tool shaft 20, is provided with spaced shaft supports 31, 31a, 31b mounted on the guideway and moved through strokes of progressively varying length in timed relation to the head. The head is moved to the left from the position shown by a cable 23, Fig. 4, and carries with it the cables 41, 41a, 41b by reason of enlargements 69 Fig. 10, on these cables being engaged by latches 67 on the head. Each of these cables is attached through springs 47, 49, Fig. 7, to a corresponding support 32 which is thus carried forward with the shaft. When the support 32 approaches the work and a stop bar 95, Fig. 4, a roller 89, Fig. 10, on the latch 67 engages an adjustable cam 88 and is lifted clear of the cable 41 so that this is no longer carried forward by the head and the support 32 is arrested by adjustable studs 96, Fig. 4. A similar action occurs as the supports 32a, 32b, reach the positions shown in Fig. 4, the head itself being arrested by stops 99. When the head 18 makes the return stroke each support is retained adjacent the work, by a catch 53, Fig. 7, engaging an abutment 55, until the catch is withdrawn by a cone 60 on the cable 41 when this is pulled to the right by the head 18 engaging an enlargement 70, Fig. 10. Each support 32 has four rollers 35 engaging guides 17, Fig. 6, and a semi-cylindrical face 37 to which a spider 38 is bolted, this having a concentric bearing 39 in halves to support the shaft 20.
