Abstract: 351,285. Stitching sheets or signatures. BREHMER GEB., 107, Karl Heinestrasse, Plagwitz. Leipsic, Germany. July 22, 1930, No. 22096. Convention date, June 6. [Classes 89 (iii) and 112.] Means for feeding sheets or signatures to stitching mechanism comprises a reciprocating gripper which conveys the sheet at the stitching location, and a belt which carries it up to the gripper and finally discharges it to a stacking arrangement. As shown, the sheets 32 are carried past the stitching mechanism 35 on a saddle 1. An endless belt 33 arranged on the rear face of the saddle and driven by a flexible shaft 50 co-operates with pressure rollers (not shown), to feed a sheet, placed on the left-hand end of the saddle by hand or automatically, up to position for the insertion of a first stitch. As this stitch is being inserted, the sheet is seized by a spring-gripper 7 on a slide 6 which is reciprocated upon the front face of the saddle by means of adjustable levers 15, 23 and a cam disc 22. The gripper, Fig. 3, is a spring blade which, at the sheetreceiving position, co-operates with a pivoted cam finger 14 which is mounted below the saddle and projects through it and through a slot 36 in the slide 6. As the slide moves to the left, the gripper 7 is raised by the finger 14, Fig. 3. At this moment, the sheet is fed by the belt 33 up to the finger 14, which acts as a stop. The slide 6 then moves further to the left, the finger 14 passes into a slot 37 in the gripper, and the latter descends to grip the sheet. When the first stitch has been inserted, the slide 6 returns to the right, carrying the sheet with it, until the stitching plate 35 descends for the second stitch, clamping the sheet to the saddle, The gripper is then pulled off the sheet. As the gripper moves to the right, it tilts the cam finger about its pivot out of the path of the moving sheet. On again moving to the left to seize a second sheet, the slide passes beneath the first sheet, since its leading edge is bevelled. After insertion of the second stitch, the sheet is carried by the belt 33 to delivery plates 26, 27, which close the sheet, turn it horizontal, and deposit it upon a spring- raised stacking plate 28. The stitching plate 35 carries a gravity stop 39 for the second and subsequent sheets. The drive of the slide 6 may be adapted for inserting one stitch only in each sheet.

Title: Improvements in or relating to a method for producing roads and the like surfaces, wall coverings and moulded blocks
IPC: C04B28/02
Filed: 1933-08-08
Abstract: In a method for producing road surfaces, wall coverings, shoe soles, rubber matting, moulded blocks and the like from mixtures of aqueous dispersions of rubber, cement, and a hydrophilic colloid, the hydrophilic colloid present is converted by chemical action into an irreversible gel prior to setting of the cement. The aqueous rubber dispersions may consist of or contain guttapercha, balata or similar resins, naturally or artificially obtained, vulcanized or unvulcanized.  Cements mentioned are Portland and Ciment Fondu.  The term "cements" includes calcium sulphate cements such as plaster of Paris.  The colloid may be a soluble alginate, or gelatin or glue. The colloid gels in a few minutes, e.g. 20 minutes, and the mixture sets later, e.g. in 24 hours.  When the hydrophilic colloid is a soluble alginate, e.g. sodium or ammonium alginate, it may be gelled by salts of calcium or other metals or by the cement.  The gelling of the alginate may be accelerated by adding alkalis or retarded by adding casein, while any tendency of the latex or alginate to premature coagulation or gelling may be suppressed by adding, e.g. sodium silicate.  When the colloid is gelatin it may, in the form of a solution slightly peptized by potassium hydroxide, be gelled by adding a form of formaldehyde to the mixture with the cement. When the mixture has been spread it may be coated or dusted with calcium chloride solution or calcium sulphate powder to expedite setting. Eight examples are given, in some of which asbestos fibre or sand are added to the mixture.  Specifications 219,635 and 290,313, [both in Class 70], are referred to.

Abstract: 915,906 Change-speed control. HOBBS TRANSMISSION Ltd. April 28, 1961 [June 24, 1960], No. 22205/60. Class 80 (2). Engaging pressure 11 supplied to two liquid pressure operated friction brakes 15, 17 of a change-speed gear, such as the planet gear described in Specification 738,590, is normally maintained at a high pressure by a regulator 30 past which engaging pressure 21 is supplied to a liquid pressure operated brake 24 and a clutch 26 maintained at a lower pressure by a regulator 47, which lower pressure acts through lines 61, 62 on the regulator 30 when the brake 24 or clutch 26 is engaged to reduce the pressure 11 to the lower level. The engaging pressure 21 is varied by an engine-throttle pedal acting at 60 on the loading spring 52 of the regulator 47 which engaging pressure is increased in all but closed throttle setting by supplying through lines 68, 66, 65 the lower pressure 21 to increase loading of the regulator 47 and is reduced in direct drive by a line 73 fed through the line 62 from the clutch line 26 which reduces loading of the regulator 47. The engaging pressure 11 is varied with the lower pressure 21 by supplying the latter through lines 68, 66, 64 to the lower end of the regulator 30, thus increasing spring pressure 40 in all but closed throttle setting in which the valve spool 51 blocks the inlet to the line 66. Control is by a sliding selector valve 13 which selectively energizes the clutch and brake lines 26, 24, 17, 15. Increase of engaging pressure 11 during downshift, by releasing brake 24 and engaging brake 17, is regulated by a restriction in the exhaust from line 61. Engaging pressure 11 is augmented in reverse by a line 80 from the selector valve which increases loading of the regulator valve 30. Specifications 777,871 and 803,874 also are referred to.
