Title: Warp knitter yarn break sensor -  has clamp drum system to trap broken yarn to stop drive when tension through the trapped yarn activates overload
Inventor: GSCHWEND RUDOLF
IPC: D03D51/20
Filed: 1990-09-29
Abstract: Mechanism to monitor a yarn break in a band of warps or other yarns, for a warp knitter, has radially opened clamp holders for the broken yarn, deflected by a force field, at the mantle surface of a clamping drum powered by the warp drum drive. The drum drive has an overload unit which, when tension is applied through the clamping drum by the deflected yarn section, disconnects the main drive and the drum drive. Pref. the mantle surface of the clamping drum is solid and sealed. The force field directed at the yarns is formed by blown air streams, with a cross section which covers the cross section of the clamping drum and extends over the two mantle sides. The clamp holders are clamping gaps with an acute-angle shape, tapering in the direction of surface rotation. The clamping gaps are in two groups, displaced from each other by at least 90 deg. in the direction of surface rotation. One group of clamps is formed by a sprung wire, on a structured path, where the coils are pressed together at one point, and the coils are at their max. gap from each other 180 deg. from this point. A short clamping drum can be at the two edge zones of the band of warpas, on its movement path. The overload unit has an electronic evaluation circuit which sets the normal long term shifting level of the load on the drum drive. The tension applied by the clamped broken yarn gives an overload reading against the current established normal level. ADVANTAGE - The system stops the operation only when a broken yarn is deflected from its path so that a stoppage is only caused by a yarn break, without false alarms.

Patent DE-4107583-A1 (DE)
Inventor: RENNER HERMANN DR
IPC: C01G55/00
Filed: 1991-03-11
Abstract: In a method for purifying raw halogen complexes of platinum contaminated by other metals of the platinum group and/or non-noble metals, which are normally an intermediate stage in the separation of the metals of the platinum group, the effective purification step is the conversion of a halogen complex of platinum which is only sparingly soluble in an aqueous medium by chemical reaction to another halogen complex with simultaneous reconstruction of the crystalline structure of the material. The method is a general method and is characterized by particularly high efficiency as regards the results of purification, the yield, very rapid throughput in simple apparatuses, low energy consumption and therefore high cost-effectiveness.

Title: Improving tenderness and flavour of fresh meat
IPC: A23B4/16
Filed: 1991-05-03
Abstract: In a new conditioning procedure, meat is placed in an airtight chamber and after at least a part of the existing atmos. is withdrawn, an oxygen atmos. is introduced. This oxygen atmos. has a purity of 50% or more, and pref. at least 90%. During the treatment time, which depending on the type of meat being treated can vary from a number of days to a number of weeks, the oxygen atmos. is repeatedly withdrawn by lowering the pressure and then replaced. The withdrawing of the atmos. takes place during a period of between a few minutes and up to six hours. The pressure in the chamber is reduced considerably below atmospheric pressure, and pressure depression of 0.99 bar is pref. reached. An almost complete vacuum is therefore produced. The oxygen atmos. is replaced pref. once or twice per day. A greater rate of pressure redn. is used in the early part of the pressure redn. process than in the later part. As an alternative, the pressure may be reduced in a step-wise manner.

Title: Winding control for paper feed to rotary printing process - modifies input to PD regulator by introducing addition signal when emergency stop is initiated
Inventor: MERZ ROLAND
IPC: B65H23/06
Filed: 1991-08-30
Abstract: A rotary printing machine uses paper for a reel (1) that is fed to the process via a dance roller arrangement (3) that accommodates variations in load. The position of the dance roller is monitored (4) and the output fed to a multiplier (5) and is also compared (6) with a reference (7).
