Abstract: The invention relates to a procedure and an apparatus for wrapping a straw fodder bale with plastic foil. In the procedure, the bale is taken up into the wrapping apparatus by means of working arms (4) by pressing the bale by its long sides between squeeze plates (10) provided at the second ends of the working arms. The bale is wrapped with plastic foil between the working arms either by rotating the bale by means of the squeeze plates (10) and a rotation means (11) or by driving the plastic foil rolls (7, 8) in an orbit around the bale. If necessary, the bale is turned through 90 DEG  from below by means of a low supporting arm before the final stage of the wrapping operation.

Abstract: Nitrofuran derivatives of the general formula (I). where R = hydrogen, methyl or hydroxymethyl. The compounds are antibacterial agents, having activity against a large number of gram negative and gram positive organisms. 147 g. N-methylaminoacetaldehyde diethylacetate was added to a solution of 115 g. acetone semicarbazone in 600 cc ethoxyethanol and the solution was refluxed for 6 hr. The solution was concentrated under reduced pressure and the residue diluted with ether. The precipitate formed was filtered off and washed with ether. The combined ether solution was concentrated under vacuum and 500 cc 10% sulphuric acid added to the residue. This solution was warmed on a steam bath and 113 g. 5-nitrofurfural dissolved in alcohol was added to the mixture which was then heated for 1 hr. on a steam bath. After cooling, the precipitate was filtered off, washed with water and dried to give 51 g. product, which was recrystallised from nitromethane to give pure 1-methyl-3-((5-nitrofurfurylidene)-amino) -4-imidazolinone-2. m.p. 238-240 deg.C.

A sheet of rubber, or like vulcanizable elastomeric material, provided on one face with projections, the tips 12 of which differ in properties from the rest of the sheet, is formed by interposing an apertured plate 9 between an unvulcanized base sheet 13 and a top sheet 12, applying pressure to sheet 12 whilst firmly backing sheet 13 so that material from each sheet flows into contact through the apertures. The sheets are heated to bond and vulcanize them when sheet 12 has been sheared around the edges of the apertures. In an embodiment shown in Fig. 7 the sheet 12, the plate 9 and the sheet 13 are placed between a recessed mould 5 and a cover plate 11 and subjected to pressure between the platens of a press. The lands between the recesses 8 are aligned with and are slightly bigger than the apertures 10 so that a high shearing force is experienced by the material between the peripheries of the lands and the apertures. The sheared off material 12a is accommodated by the recesses 8, the assembly being heated when the position shown in Fig. 7 has been reached.

Title: Improvements relating to hydraulic brakes and the like
IPC: F16D51/14
Filed: 1945-01-18
Abstract: 628,948. Brakes. MEIKLEJOHN, M. F. Jan. 18, 1945, No. 1539. [Class 103 (i)] [Also in Group XXIV] In a brake having shoes which are moved radially outwards, against the brake drum, by a resilient member which is expanded by hydraulic pressure, means are provided for bridging the gaps between the shoes, so that circumferential continuity of the inner periphery of the shoes is substantially maintained during operation. As shown, four shoes 1 are arranged within the drum 2, the webs of the shoes being slidably guided in a deep groove 6a in a member 6 secured to the back-plate 4, the webs having overlapping extensions 1b of reduced thickness which provide continuity of abutting surface for the resilient ring 7 when the shoes are expanded. The ring 7 is preferably of oilresisting synthetic rubber and fluid is admitted to expand the ring by a connection 8 leading to the master cylinder. The braking-torque is taken by pins 3 on the back-plate, the holes in the webs being either radial or inclined to radii. Adjustment for wear is effected by angular adjustment of a stepped spiral cam 9 which acts as a stop for pins 10 on the webs. In a modification, Fig. 6, the overlapping extensions 1b of the webs are replaced by separate tongues 19 which slide into slots in the adjacent ends of the webs. A protuberance 11a on the tongue 19 prevents abrasion of the ring 7. The torque is taken by a pin 17 connected to the shoe by a link 18 and pivot 16. The shoe, when the drum rotates in the direction of the arrow A, tends to turn anti-clockwise on the pivot 16 and, to prevent undue lining wear at the leading end of the shoe from this cause, the part of the shoe ahead of the pivot 16 is of greater length than the part of the shoe behind the pivot. The mounting of the shoe on the pin 17 results in self-augmentation in the shoe application to the drum. The shoes are operated mechanically for parking, two diametrically opposite shoes being applied positively, the two other shoes being applied by the sliding wedge action at the joints between the shoes. Specifications 581,283 and 606,518 are referred to.
