Abstract: 1471802 Ground drainage HEIDEMAAT SCHAPPIJ BEHEER NV 18 April 1975 16181/75 Addition to 1214175 Heading A1B [Also in Division El] When excavating a site in which the groundwater level is lowered before the excavation is commenced or completed to its final depth, the dewatering is effected by means of at least one dewatering pipe 6 connected to a well pump 9 and introduced into the ground at a position beyond the area 5 in which excavation equipment or labour is to operate and extending underground therefrom towards the area to be excavated, the dewatering pipe including a perforate or water permeable portion 7 disposed below the final depth in the vicinity of the area to be excavated. The perforate portion 7 of the dewatering pipe may start near the end of a previously laid dewatering pipe 10. The dewatering pipe is laid in a deep trench 12 made by a chaintype trench digging machine before the main excavation, e.g. trench 1, is started. Preferably the perforate pipe 7 has helical grooves, the perforations being formed in the base of the grooves, and the pipe is wrapped in a cover of nylon cloth. One end of the perforate pipe 7 is closed and the other end is connected to the pump 9 via pipe 6. After the excavation has been completed only the pumps 9 need be removed. The excavation may be a trench 1 used for laying a pipeline, the perforate pipe 7 being disposed below a bottom corner of the trench, as shown, or may be for a canal or for footings, the pipe 7 being disposed below the centre line of the trench.

Title: Improvements in meat treating method and product
IPC: A22C7/00
Filed: 1930-05-28
Abstract: 351,700. Cutting carcasses into parts. SWIFT & CO., Union Stock Yards, Chicago, U.S.A. May 28, 1930, No. 16431. Convention date, June 6, 1929. [Class 28 (ii).] A carcass part is chilled to rigidify it uniformly and it is then sliced to produce retail cuts. The chilling is preferably effected by quickly freezing the outer portions, and then " tempering the meat at a higher temperature to allow the outer portions to become less brittle and the central parts to become more rigid. The slicing is effected on a heavy machine either of the disc knife or guillotine knife type. The slices may be wrapped individually or they may be re-assembled in their original form and the carcass part wrapped as a whole. The slices, as shown in Fig. 4, may be joined together by unsevered skin 5, and retained in shape by end pads 6 joined by a wire 6<1>. Before slicing a loin, Fig. 10, the ridge 7 of the spinal bone is trimmed off either along a plane A-A or a plane B-B. This makes the chops appear smaller, and it is stated that small chops command a higher price per lb. than large chops. The slicing is effected uniformly, irrespective of the positions of the bones, as shown in Fig. 10. The chops may be wrapped individually or in pairs, or the whole sliced loin may be wrapped, or the best chops may be wrapped and the inferior ones packed in pails for bulk sale.

Washing-machines with closed or enclosed rotary receptacles.-The air or other gas used for assisting agitation of the materials in rotary or oscillating washing &c. machines is introduced by means of steam- or liquid-jet injectors. As applied to the ordinary rotary washing machine, ga.s &c. is introduced through a stationary trunnion tube D. Fig. 1, which communicates through the box E with the lower members of a series of radial tubes F by which the gas &c. is delivered to hollow perforated lifters B of the rotary drum A. Alternatively, the drum may be mounted as shown in Fig. 3, in which case it is provided with hemispherical ends L<1> in which are fitted hemispherical shells R; the gas &c. is supplied through the trunnion tube D and passes to the lower pipes F as before, escaping through perforations in lifters S and through the perforations V, W of the shell R; the perforations V are simple circular holes so that the injected gas &c. gives an upward motion to the contents of the drum, while the perforations W are in the form of struck-up nibs and the gas passing therethrough produces a rotary motion of the materials. A discharging door T provided also with a drain cock is provided on one of the ends of the drum. When applied to an oscillating type of machine such as that shown in Figs. 4 and 5, in which the vessel a supported by links b is oscillated by crank and connecting-rod mechanism c, d, a perforated pipe f connected by a flexible pipe to the injecting apparatus, is laid along the bottom of the vessel. A suitable arrangement of injecting apparatus is shown in Fig. 6 : injectors X, 4 supplied respectively with cold water and steam respectively, inject air into a vessel 3 in which the steam is condenser by the aerated spray, and the liberated air is forced through the pipe 6 to the trunnion tube of the washing- machine 7; the water passes through a U-tube 2 or a regulating valve to the hot water tank 1; if hot treatment is desired, then air or other gas is introduced into the washing-machine by means of a steam-jet injector 10. This injector is also used for the introduction of chemical or colouring liquids.

[Also in Group XXIII] A cutting-element is attached to a support such that the combination forms a hand-file or rasp, or a flat or rotary cutting-tool. The cutting-element comprises a metal sheet having a number of teeth providing cutting-edges having positive rake and clearance-angles, which edges are formed by marginal portions of holes formed in the sheet, and non-cutting surfaces to limit the depth-of-cut are provided in the form of protuberances projecting from the sheet. As shown in Fig. 1, the cutting-edges of the D-shaped holes 2 are arranged in transverse lines and almost every tooth is associated with one dimple 12. The holes are punched in a sheet of hardenable metal, the marginal portion of each being upset to form a tongue 5, the projecting end of which is ground parallel to the face 6. Each sharpened tooth is corrugated to provide the clearance angle C<SP>1</SP>, by displacement away from the surface 6 of a portion 7 near the root 8, and the progressive bending of an intermediate portion 9 of the tongue towards the face 6, the dimples 12 being embossed in the same operation. In a modification, Figs. 6, 7 (not shown), ridges are provided parallel to the lines of holes, and intersecting the holes. In other modifications, Figs. 8-11 (not shown), the protuberances are ramp-like tongues upset from the sides of holes opposite the teeth associated therewith, the holes being either D-shaped or square. In another modification, Fig. 12 (not shown), opposite marginal portions of each rectangular hole are oppositely-displaced to form teeth projecting from both faces of the sheet. Modifications are also described having teeth which are not corrugated at the root, one such element, Fig. 13, having D-shaped holes 2 and ramp-like tongues 12<SP>11</SP> upset from the sides of the holes opposite the teeth. The tongues 12<SP>11</SP> are upset by a punch 30 and die 31, the punch being located by a finger 32 adapted to project into the hole and to bear against the margin thereof opposite the tooth, the operative travel of the punch being checked by contact of the inclined-surface 33 and land 34 with the upper surface of the blank. A similar method of upsetting the teeth is applicable to the constructions shown in Figs. 1-11. Specifications 666,573, 666,621, 666,622, 695,830 and 695,859 are referred to.

Capsule closures.-Relates to crown-cork bottle closures consisting of a crimped-rim metallic cap carrying a resiliently-backed facing-disk of American cloth, and consists in applying to the contact face of the disk a superficial film of an innocuous substance which is incapable of adhering to a vitreous surface. The substance may be either a flexible wax or a grease which is hard and solid at normal temperatures, preferably hard paraffin wax or hard stearin; or it may be an innocuous agglutinant with whiting, talc, fuller's earth, or like absorbent powder mixed therewith. A wax or hard grease film is preferably used for capsules for bottles containing alcoholic liquors, and an agglutinant film containing glue in the case of oily substances. The sheet of American cloth is coated with the material before the disks are punched out. The wax or grease may be dissolved in a vaporizable solvent and be painted or sprayed on to the cloth, and the solvent evaporated off. The non-greasy type of dressing consists of an innocuous agglutinant, such as a mixture of flour paste and dissolved glue or casein, and an innocuous absorbent powder.
