Title: Small increment ribbon feed
IPC: B41J33/22
Filed: 1967-01-05
Abstract: An ink-ribbon mechanism, which is mounted on a movable carriage for feeding of an ink ribbon 21 capable of receiving up to six overstrikes and for feeding of the ink ribbon at constant increments irrespective of the dia. of the supply or take-up spools 22, 27, is provided with a brake 30 which causes a garter spring drive 40 to slip when the incremental length of ink ribbon has been fed. The ink-ribbon 21 is supplied from a spool 22, which is acted upon by a tensioning brake 25, then advanced in front of a printing station 13 by ink ribbon vibrator guides 24 and subsequently passed over guide posts 31, 32 and back again over the guide post 31 (which constitute the brake 30) before being trained over a guide post 26. The inkribbon is then wound on the take-up spool 27, which is driven by the slip drive formed by a garter spring 46 wrapped about driven pulley 45 and driving pulley 44, the latter being advanced by a cam oscillated pawl 41 which engages in apertures 43 of a ratchet wheel 42. The guide post 31, which in conjunction with the post 32 forms a brake 30, is mounted on a bracket 34 pivoting about post 32 under the bias of a spring 35 to vary the wrap-round of the inkribbon about the post 31 and thereby vary the drag force exerted by the brake 30 on the inkribbon. Angular displacement of the bracket is limited by a setting screw 36.
Patent ES-339373-A1 (ES)
Title: Brake system
IPC: B60T13/58
Filed: 1967-04-15
Abstract: In a motor vehicle brake system, a pressuremedium operated friction brake 4 and a hydrodynamic brake 1 are adapted to operate on the same wheel axle, the hydrodynamic brake being adapted to influence the friction brake, wherein a charging cylinder 3 supplying pressurized fluid to the hydrodynamic brake can be operated at choice by excess air pressure or by vacuum, the change over from vacuum when the vehicle is unbraked to excess pressure when the vehicle is braked being performed by a combined control valve 6 which is controlled by a master cylinder 5 adapted to apply pressure to the friction brake and cause actuation of a change-over valve 10 to disconnect the charging cylinder 3 from the vacuum reservoir 12 and connect the cylinder 3 to the compressed air supply. The combined control valve 6 as well as being controlled by the master cylinder 5 may be controlled independently of the hydraulic brakes by means of a manuallyoperable lever to actuate only the hydrodynamic brake during a prolonged descent of the motor vehicle. In operation, when the vehicle is moving along a road without the need for the brakes to be applied, a compressor 15, driven by the engine, sucks in air via a vacuumoperating valve 13 and a suction filter 14 to produce a degree of vacuum in the vacuum reservoir 12. This vacuum is propagated via a line and an oil separator 11 to the change-over valve 10 and acts on the air space above the liquid level in the charging cylinder 3 so that the hydrodynamic brake 1 is under the same negative pressure and the idling losses of the hydrodynamic brake are kept to a minimum. When the brake has to be applied, the driver depresses the pedal operating the master cylinder 5 to pressurize the friction brakes of the vehicle and, via the compensating valve 7, changes over the combined control valve 6 to connect a compressed-air reservoir 2 to the change-over valve 10 and allow compressed air to enter the charging cylinder 3 and operate the hydrodynamic brake 1. Tappings 16 in the casing of the hydrodynamic brake allow pressure produced in the hydrodynamic brake to influence the compensating valve 7 and so control the effect of the friction brakes in dependence upon the braking effect of the hydrodynamic brake. The oil circulating in the hydrodynamic brake 1 is cooled in the heat exchanger 8.

Title: Method for degreasing rolling mill scale
IPC: B08B3/08
Filed: 1976-07-21
Abstract: Rolling mill scale to be degreased is weighed, thoroughly mixed with from 10 to 20% by weight of a solvent e.g. a fluorized chlorohydrocarbon, while finely distributing the grease in the thus obtained mixture. The mixture is then added in a continuous manner to a bath containing such solvent, and is distributed therein. The rolling mill scale is then slowly moved out of the solvent containing bath while mixing the rolling mill scale with an oil-free solvent of the above mentioned type passed in countercurrent flow to the last mentioned mill scale. The movement of the thus obtained last mentioned mixture is continued while causing the solvent to drip off out of the grease-free rolling mill scale. The rolling mill scale is then heated, and the residual solvent is driven out of the rolling mill scale. Finally, the grease-containing solvent is regenerated by distilling the same, and the oil-free solvent is condensed and fed back to grease-covered rolling mill scale to be degreased.
