Title: Colour TV tube with index targetting control - has light emitting reference strips between three colour phosphors and photocells to detect emissions
Inventor: GEYER ARTHUR
IPC: H01J29/70
Filed: 1980-02-25
Abstract: Between each group of the three basic colour phosphors is a light absorbing strip. The phosphors - red, green, blue - and the light absorbing strips have a metallised rear coating with light emitting strips - the index strips - on the rear corresp. in position to the light absorbing strips. The index strips emit either UV or IR light if the electron beams strike them. The emitted UV or IR is picked up by photocells in the rear of the tube so that the divergence error can be measured. One photocell responds to UV light, the other to IR, and the outputs are used to correct the divergence of the guns using signals to the deflection circuitry. One index strip can provide light measured by one photocell while the second index strip provides light to which the second cell responds.

Patent DE-3012361-A1 (DE)
Title: Semiconductor laser - with diffusion front at specified approach to laser active layer
Inventor: GOTTSMANN HRTMUT DIPL PHYS
IPC: H01S5/22
Filed: 1980-03-29
Abstract: The parent patent no. 2822146 described a semiconductor laser with a sequence of layers in the form of a heterostructure diode. Diffusion of a dopant through the structured surface has produced a diffusion front which extends nearly to the laser active zone. The distance of the diffusion front from the laser-active zone is made so short (0-0.5 mu) that a substantial part of the optical laser light penetrates into the diffusion front. This yields an optimum distance which increases the laser stability by maximising the near field with of the laser emission and by reducing the effective refractive index below the surface groove.
Patent DE-3016214-A1 (DE)
Title: Improving protein provision of cattle esp. milk cows - by adding hydrolysed feather meal to the feed
IPC: A23K10/26
Filed: 1980-04-26
Abstract: New method for improving protein provision for cattle (esp. in the first third of the lactation period) comprises adding hydrolysed feather meal (I) to the cattle feed. New cattle feed contains (I) and rumen-resistant amino acids. (I) has ahigh protein content but is resistant to digestion and degradation in the rumen,only being digested in the later stages of the digestive system of cattle. It thus offers a cheap and effective alternative to 'protected proteins', which have previously been used to overcome the degradative effect of the rumen on added dietary protein. When milk prodn. is greater than 20 (esp. greater than 25) litres per day, (I)is pref. administered in an amount of 300-1500 g. per cow per day. The cattle feed pref. contains the hydrolysed feather meal in an amount of 5-50 wt.%.

Title: Deviation measuring system for trench construction - uses inserted rod with hollow guide cage and two measured inclination angles
Inventor: NUSSBAUMER MANFRED DIPL ING
IPC: E02D17/13
Filed: 1980-05-30
Abstract: The method is for measuring deviations arising during construction of trenches and requires only one measurement process at each depth. An approximately rigid elongated rod (2) is fed in guides along the trench (4) walls (14). The inclination is then measured at two or more points separated in the longitudinal direction. The rod has a sliding guide body (7) at its lower end to enable it to be fed along the trench (4). The guide body is a hollow cage in contact with both sides of the trench. The inclination in between the points is determined from the average of angles between the rod tangent at a fixed point and vertical and between the rod tangent and vertical where the rod joins the guide body.

Title: Low loading railway wagon for transporting road vehicles - has rotatable centre section carried on rollers to facilitate loading
Inventor: BEHRENS RUDOLF
IPC: B61D47/00
Filed: 1980-09-09
Abstract: The low-loading wagon (10) is designed for transporting heavy road vehicles (29) or large capacity containers by rail. The wagon (10) has a frame consisting of two side members (11) supported at each end by a bogie. The middle section (12) of each side member is below the level of the end sections supported by the bogies.

Title: Process for the preparation of pure acetoacetamide which is stable on storage
Inventor: KUENSTLE GERHARD DIPL CHEM DR
IPC: C07C231/04
Filed: 1981-01-20
Abstract: The invention relates to a process for the preparation of pure acetoacetamide which is stable on storage, in which the reaction of diketene and ammonia is carried out under anhydrous conditions in the presence of aliphatic chlorohydrocarbons using an excess of diketene of 0.01 to 2 % of theory and at temperatures of < +10 DEG C. The stated amounts of excess diketene are in this case proportioned such that an aqueous extract of the reaction mixture obtained has a pH of 6 to 7. The acetoacetamide is separated off from the suspension obtained by centrifugation at temperatures of < +10 DEG C and dried under reduced pressure at temperatures up to 50 DEG C. The acetoacetamide thus obtained has a degree of purity of at least 99 % and is stable on storage at room temperature in virtually unchanged form without further purification or stabilisation measures.
