Title: Railway sidings goods wagon dispersal system - has downhill brake control using run-off speed dependent on travel length to point of separation from preceding detachment
Inventor: SCHMIDT EBERHARD DIPL ING
IPC: B61K7/12
Filed: 1976-12-02
Abstract: The downhill brake to be controlled is in a run-off layout in railway sidings. Goods wagons are detached from trains and forwarded on sloping tracks for disposal to different points, with conveyor devices in the dispersal tracks. Each detachment following a previous detachment is braked in a downhill run brake section to a run-out speed derived for its length of travel up to the point of separation from the previous one. This produces a running time which is at least as long as that of the preceding detachment, increasing with a growing interval for the following detachment.

Patent DE-2658337-A1 (DE)
IPC: B30B9/30
Filed: 1976-12-23
Abstract: The press has a pressing chute (3) in which a reciprocating piston (2) presses the waste to be poured in in each case against a lockable door (6). Tapes (8) used to tie up the fully pressed bales (7) are guided along the inside walls of the pressing chute and held by means of individually pivotable clamps (11), the said clamps being arranged on the underside and top (3a, 3b) of the chute at approximately the same horizontal distance (a) from the pressing-chute door (6) in each case. Spacing and retaining elements (10) which point in the pressing direction (D) of the piston (2) keep the waste material away from the chute walls in order to prevent jamming of the piston and in addition prevent any springing back of the compacted bale layers in each case. The tapes (8) extend laterally alongside the spacing and retaining elements (10) which are designed so as to be at least as high as the clamps (11). <IMAGE>

Title: Hot melt cartridge adhesive gun - has trigger operated plunger to move adhesive into contact with heater and retractor operated by trigger release
Inventor: ORNSTEEN ROBERT L
IPC: B05B7/16
Filed: 1977-01-13
Abstract: A plunger is driven into engagement with the cartridge by a manually operative trigger actuated ratchet to urge the cartridge into contact with an electrical heater block and to provide pressure for driving the melting adhesive into a storage reservoir and out through a valved nozzle. A partially melted portion of the cartridge deforms under the applied pressure of the plunger to form a seal against backflow of molten adhesive. Upon release of the trigger, a retraction mechanism causes the plunger to retract a predetermined amount to disengage the cartridge thereby allowing closure of the nozzle valve and arresting of adhesive flow.

Title: Brake accelerator for fluid-pressure brake system - has control valve with emergency brake piston subjected to brake line pressure and control chamber pressure
Inventor: STAEUBLE GEORG
IPC: B60T15/22
Filed: 1977-08-23
Abstract: The brake accelerator has a control chamber connected through a throttle orifice to a brake line. The brake system includes a control valve in which is an emergency brake piston one side of which is subjected to brake line pressure and the other side of which is subjected to pressure in the control chamber. The emergency brake piston, as a function of a pressure drop in the brake line, opens a brake line outlet valve so that air flows from the brake line through an inlet valve. The inlet valve is held by a control piston in its open position at the start of a pressure drop in the brake line and the air is flowed into a chamber to form a control pressure. The control pressure acts on the control piston to open an outlet valve for tapping or drawing off the air from the chamber and also to close the inlet valve.

Title: Poly:cyclic aromatic hydrocarbon(s), e.g. 3,4-benzpyrene, determn. - by thin layer chromatography on silicon di:oxide-hydrophobised silica gel plates
Inventor: HAUCK HEINZ-EMIL DR
IPC: G01N30/90
Filed: 1978-06-19
Abstract: In the semi quantitative determination of polycyclic aromatic hydrocarbons by thin-layer chromatographic (TCL) sepn. of a soln. of the hydrocarbons on a coated carrier, (A) the specimen to be examined is applied to a carrier containing (1) a concn. zone consisting of a synthetically produced porous SiO2 of medium pore vol. with a pore width of 2-15 mu m and (2) a sepn. zone consisting of a silica gel layer with a surface modified by reaction of the coated carrier with a methyl-alkyl-dichlorosilane (the alkyl group being 12-20C), and (b) subsequently eluting with an organic solvent or solvent mixt. Used for detection/determination of polycyclic hydrocarbons such as the carcinogen 3,4-benzpyrene in e.g. waters such as waste waters, surface waters, ground water or drinking water. The hydrophobic nature of the sepg. zone prevents absoprtion of water from the air and premature activation of the adsorbent. This improves the reproducibility of results. Flow-rate through the carrier is high, since the soln. experiences no resistance at the interface between the concn. and sepn. zones.
