Title: Improvements in or relating to the separation of materials having different settlingrates in liquid such as water
Inventor: HARDINGE HARLOWE
IPC: B03B5/36
Filed: 1951-09-25
Abstract: 731,531. Washing granular materials. HARDINGE CO., Inc. Sept. 25, 1951, No. 22387/51. Class 82 (2). Particles are classified according to their settling rates in a body of liquid of specific gravity lower than that of the lightest particles by introducing a mixture of the particles into the body of liquid having a submerged moving supporting surface travelling through it so that the faster settling particles settle on the moving surface while the slower settling particles are kept in suspension in the liquid by eddy currents caused by the moving surface, removing the particles which have settled on the moving surface at one point and removing the particles in suspension in the liquid at another point. One form of apparatus for carrying out this process (Fig. 1) comprises a circular tank 1 containing the liquid and a circular submerged disc 4 rotated by a shaft 5. The particle mixture is fed in at 9 and the faster settling particles are removed from the disc by a scraper 15 and a screw conveyer 12 whilst the particles remaining in suspension are removed with the liquid overflowing at 2. In another similar form, the disc is inclined to the horizontal and the faster settling particles are removed by a scraper from the upper part of the disc which projects above the liquid surface. In further forms, Figs. 5 and 10, the moving surface comprises one or more endless conveyer belts 21, 26, 40 which remove the faster settling particles, the particles in suspension being removed by overflowing the liquid at 24 and 47. The scraper 52, for removing the particles from the belt 40, may be replaced by one or more jets of liquid.

Title: Process for the dihalogenation of acrylic acid esters and their homologues
IPC: C07C17/02
Filed: 1955-08-04
Abstract: Esters of a :b -dihalopropionic acid and homologues thereof are produced by dihalogenation of the corresponding acrylic acid esters in the presence of a non-heterocyclic tertiary base (e.g. a dialkyl-aniline or -naphthylamine, preferably in a molar proportion of 0.1 to 20 per cent, advantageously 5 to 15 per cent, calculated on the amount of ester).  The reaction is advantageously carried out at - 20 DEG  to +30 DEG  C. (preferably at 0-20 DEG  C.), if desired in the presence of an inert solvent (e.g. carbon tetrachloride or a dihalogenated, otherwise unsubstituted or a -alkyl-substituted propionic acid ester such as methyl dichloropropionate), and in many cases is favourably influenced by irradiation with daylight or ultra-violet light (before, during or after the introduction of the halogen).  In an example, chlorine passed into an ice-cooled mixture of methyl acrylate and dimethylaniline to produce methyl dichloropropionate.  The use of bromine is also referred to.

Title: Improvements in and relating to edible jellies
IPC: A23L29/231
Filed: 1935-08-09
Abstract: Materials for making an edible jelly are prepared and packed by first incorporating the flavour into the sugar by adding it to heated or melted sugar which may then be broken, granulated or powdered or kept as tablets, &c., or by adding the flavour to a supersaturated solution of sugar prior to crystallization, or by passing the vapours of the flavour, if volatile, into the sugar which absorbs it, the flavoured sugar being placed in a vapour-proof main package with an amount of edible acid preferably in powdered form sufficient to give the optimum concentration of hydrogen ions in the jelly when made, and also, if desired, a colouring matter.  In another vapour-proof package is placed dried and preferably finely divided pectin to which may be added sugar, which may be flavoured, and buffer salts, this package being included in the main package.  The acid may be enclosed separately in a further package which is also included in the main package.  The acid used may be tartaric, malic, oxalic or citric acid separately or in admixture, and the buffer salts potassium or sodium tartrates or nitrates, malates or oxalates, or mixtures thereof.  In an example, 200 gm. of sugar, in which flavour and colouring material are incorporated, and 2,08 gm. of tartaric acid are added to the main package to which is also added a package containing 5,2 gm. of dry pectin, 0,62 gm. of Rochelle salt and 5 gm. of sugar.  In making the jelly, the contents of the pectin package are added to nearly boiling water, the mixture is stirred and the contents of the main package added to the solution obtained.  The mixture is finally poured into a vessel and allowed to cool.  The Provisional Specification describes the enclosure of the pectin and of the flavour in hollow bodies of sugar which are disposed in the other ingredients.

Title: Improvements in toys
IPC: A63H17/06
Filed: 1944-11-16
Abstract: 589,143. Toys. GREENWOOD, A., and WHITEHOUSE, F. R. B. Nov. 16, 1944, No. 22638. [Class 132 (iii)] [Also in Group XXVI] A self-driving toy has the axle of a pair of running wheels connected to one end of a long elastic member, which passes over pulleys or guides and has its other end fastened to a non- driving part of the toy, so arranged that the axle to be driven can be manually rotated, the elastic member being stretched and wound around the axle, the contraction of the main length of elastic unwinding the wound part and thereby driving the toy. As applied to a toy truck (Fig. 3), one end of an elastic member 15 is secured to the rear axle and the other end is secured to the body of the truck, the member passing over two pulleys 17, 19 slidably mounted on the front axle and a shaft at the rear of the truck respectively. A handle 16 attached to one of the rear wheels enables an operator to wind the elastic member on to the rear axle and, when the motor is wound, a lever 23 may be brought into engagement with a pin 22 projecting from the rear axle to prevent the latter from rotating. On releasing this lever, the rear axle and wheels rotate due to the contraction of the elastic member. A self-tipping mechanism may be incorporated (Fig. 4), in which the tipping body is normally held in a horizontal position by a sliding bolt 31 which engages a socket 30 carried by the tipping body. A spring member 33 is secured to one of the rear wheels which, when the truck is proceeding in a forward direction, springs over the downwardly projecting end 32 of the bolt 31. When the elastic member has unwound, the inertia of the truck winds it on the rear axle in the reverse direction so that a small reverse movement is imparted to the truck, whereupon the spring member 33 engages the end 32 of the bolt 1 and withdraws it from the socket 30 allowing the body to tip under the action of a length of elastic or spring 28. The body may be locked by a bolt 29 which also engages the socket 30.

Title: Method of meshing corrugated tapes
IPC: B23K20/04
Filed: 1960-06-29
Abstract: 882,759. Sheathing cables; corrugating. WESTERN ELECTRIC CO. Inc. June 29, 1960 [July 13, 1959], No. 22713/60. Classes 83 (2) and 83 (4). . A method of meshing corrugated tapes comprises corrugating a pair of tapes with different numbers of corrugations per unit length, moving the corrugated tapes at different speeds such that the product of the number of corrugations per unit length and the speed of each tape are substantially equal, bringing the tapes together and matching corrugations of one of the tapes to corrugations of the other tape, and then pulling the two tapes at the same speed to stretch the lower speed tape to have the same number of corrugations per unit length as the higher speed tape. Aluminium tape 10 is corrugated in apparatus 12 with a higher number of corrugations per unit length and a slower speed than steel tape 11 corrugated in apparatus 13, the product of the speed and number of corrugations being the same for each tape. The steel tape 11 is guided to a freely rotatable wheel 18, having an undulated periphery which matches the corrugations in the tape 11, and then guided into a forming device 19 which may form the tape around a telephone cable. The aluminium tape 10 is guided around a stationary member 22, adjacent the wheel 18, between which member and the wheel the two tapes are matched corrugation for corrugation, the tape 10 then being fed into the device 19. Once past the guide 22 the tape 10 springs back to shape and is stretched by the device 19 to have the same number of corrugations per unit length as the tape 11.

Filed: 1975-05-23
Abstract: 1487699 Magnetic storage arrangements INTERNATIONAL BUSINESS MACHINES CORP 23 May 1975 [5 Aug 1974] 22869/75 Heading H3B In a magnetic bubble domain storage arrangement which comprises rows and columns of bubbles D, Fig. 1, confined by a guide rail 24 and maintained in lattice disposition by the interactive forces between them, the bubbles may be displaced along the rows for reading or writing purposes, with the integrity of the lattice maintained, by appropriate expansion and contraction of buffer stripe domains S at the ends of each row. The lattice shown is divided into upper and lower portions by an interaction line 44 such as a sputter-etched groove in the domain-supporting medium 22, movement of the bubbles D in a selected portion being effected by current in an associated propagation conductor group 28 or 29. The length of the buffer stripe domains S may be adjusted to maintain the lattice integrity by a gradient field produced by appropriate energization of buffer conductors 40 to 43, or the buffer stripe domains may be allowed to adjust in length without this control. Alternatively movement of the bubbles may be effected by control of the stripe domain lengths alone. The storage arrangement is described in terms of bubble movement to the right in the upper portion and to the left in the lower portion, movement being restricted to positioning a selected subcolumn of bubbles at a column accessing device 26A to 26C where reading and writing by vertical bubble movement may take place. An alternative arrangement of a buffer conductor 46 to produce a stripe domain controlling gradient field is shown in Fig. 2. The guide rails 24 may also consist of a sputter etched groove. Alternatives for the guide rails and interaction line may be other thickness changes of the domainsupporting medium, ion implantation or diffusion, or current carrying conductors.
Patent GB-406022-A (GB)
Title: Improvements in and relating to the teeth of toothed bevel wheels
IPC: B23F5/12
Filed: 1932-08-15
Abstract: 406,022. Gear-cutting. P. I. V. KETTEN & GETRIEBE GES., 3, Industriestrasse, Bad Homburg, Germany. Aug. 15, 1932, No. 22902. Convention date, Aug. 13, 1931. [Class 83 (iii).] In a method of planing the teeth of bevel wheels, particularly the wheels used in the change-speed gears described in Specification 228,838, [Class 80 (ii), Gearing, Variable-speed &c.], the wheel blank 1 performs three motions with respect to a reciprocating shaping cutter 4 viz., a rotary motion, a vertical depth feed motion and a lateral motion perpendicular to the path of the tool. In Fig. 1 the views are taken in the direction of the shaping tool 4 and the line M indicates the centre of the blank, while 2 and 3 indicate the small and large ends of the tooth space respectively. During the first part of the operation, (diagrams 1, 4 and 7), the blank rotates continuously and is moved vertically up to the cutter to feed the cutter to depth and shape one side of a tooth space. There is also a lateral movement of the blank as is seen by the displacement of the centre M relative to the tool. During the second part of the operation, (diagrams 8, 12, 17, 21), the blank is turned without vertical movement and the lateral movement is such that the tool always passes correctly through the inner tooth gap 2. During the third part of the operation, (diagrams 22, 27) the lateral and rotary movements of the blank are continued while the blank is withdrawn from the tool and in the fourth stage, (diagrams 28, 31), the blank rotation, in conjunction with reversed lateral movement of the blank serves to transfer the tool to a position for operating on the next tooth space. In a modification, Fig. 2, the blank does not rotate during the first part of the operation but is only moved vertically and laterally to feed the tool to depth. In a further modification, only the vertical feed is employed for the first part of the operation. In some cases the tool is moved in an arcuate path so that the pitch surface of the teeth is curved in axial section. In a machine embodiment operating by the method shown in Fig. 1 and producing arcuate teeth the tool holder 8 is mounted on a vertical slide carried on the front of a ram 7. Levers 53, 55 impart an oscillatory movement to a spindle controlling the vertical slide to move the tool up and down during its stroke and cause it to move in an arcuate path. The blank 10 is mounted in a head 9. A base frame 11 has front guides 12 and roller bearings for a member 16 which has inclined surfaces 17, 18 supporting, through roller bearings a carrier 21. The blanksupport 24 is prevented from lifting in its bearings by holding-down rollers 25 and carries a worm-wheel driven by a worm 30 operated by ratchet mechanism. A cam-shaft 35 driven from the worm shaft carries a cam 42 bearing against a fixed roller 43 and a pair of cams 45 bearing on rollers carried by the member 16. These cams impart the required lateral feed to the work and also, by relative movement between the parts 16 and 21, the vertical depth feed.

Abstract: 1500068 Echo-sounding ELECTROACUSTIC GmbH 23 May 1975 [26 Oct 1974] 23060/75 Heading G1G An echo-sounding system of the type in which echo signals from a selected partial depth range are stored during one sounding cycle then read-out from store to a CRT or recorder during a succeeding cycle, and a triggering pulse to mark the beginning of the selected partial depth range is generated by a comparator 5 when the count in a binary depth counter 2 matches the count in a bidirectional binary counter 4 which has been preset to a count equivalent to the beginning of the partial range, is characterized in that outputs 6 from the stages of counter 2 are fed via gate circuit 10 to pre-setting inputs for the corresponding stages of counter 4, a threshold circuit 13 detects the sea bottom echo on an amplitude basis, and a changeover switch 15 is provided. The switch 15, when temporarily moved to the dotted line position, allows the bottom echo to enable gates 10 so that the prevailing count in counter 2 is loaded into counter 4. When the switch 15 is returned to the position shown the count in 4 is decremented by counting down a selectable number of pulses from source 11. This number determines the extent of the partial range and is set at 12. By this means the partial range is set to begin e.g. 10 metres above the bottom. Sea bed depth is displayed at 17 on numerical indicator tubes, when counter 4 is loaded with the count from 2.
