Title: Straw based fodder, esp for ruminants - contg molasses binder and powdered additives such as urea, wheat bran etc
Inventor: BALLHEIM WILFRIED
IPC: A23K10/32
Filed: 1975-02-26
Abstract: Fodder, esp. for ruminants, consists of chopped straw mixed with molasses, and conventional powdered additives such as sources of proteins, minerals etc. The pref. additives are urea and/or dried lucerne, and/or linseed press meal and/or wheat bran. The molasses bind the straw; prevent dusting and hold the powdered additives; the compsn. remains homogeneous even when pressed into blocks etc. for automatic feed dispensing. The fodder is inexpensive and can be adjusted to suit requirements by selection of the additives.

Title: Rotary compressor with eccentrically mounted piston - has flat on cylinder bore between inlet port and sliding vane
Inventor: SCHNEIDER ULRICH DIPL ING
IPC: F04C18/356
Filed: 1975-03-15
Abstract: The compressor has a casing (1) with a cylindrical bore (2) within which a rotary piston (4) is mounted eccentrically on a central shaft. The casing contains an inlet port (8) and a discharge port (9) and has a radially sliding vane (6) between them which presses on the piston and divides the space between the piston and cylinder bore into a suction volume (10) and a discharge volume (11). The piston rotates in the direction (f) from the discharge port to the suction port. The cylinder bore has a flat (14) machined between the leading edge of the suction port (8) and the trailing edge (13) of the sliding vane slot. This reduces the impact as the piston passes the vane slot and thus reduces both wear and noise.

Title: Mounting of cams onto programme plates - has V-grooves for location into machine tool and into setting machine
Inventor: WOLLENHAUPT JAKOB
IPC: G05B19/06
Filed: 1975-03-15
Abstract: The method is for the setting and mounting of cams onto a programme plate for traverse control. The plate is mounted on V -grooves and against end stops for longitudinal positioning. The cams are set in accordance with traverse movements and the plate is then removed from the machine tool and mounted on V -grooves and against end stops into a setting machine (1). The positions of the cams are measured and recorded so that the unit can be dismantled and later re-assembled and re-mounted into the machine tool for the repeated manufacture of the same workpiece.

Title: Utilizing high-boiling residues from isoprene mfr - by decomposition with water over alumina then calcium phosphate catalysts
Inventor: BART JEWGENIJ WASILJEWITSCH
IPC: C07C45/51
Filed: 1975-04-04
Abstract: The high b.pt. residues (A) produced in the first stage of the synthesis of isoprene (I) by the dioxan process, to give (I), isobutylene (II) and HCHO (III), are processed by catalytic decompsn. of (A) in presence of water at wt. ratio (A): water of 1:1-2 in 2 stages, over an Al2O3 catalyst at 250-290 degrees C to give a vapour mixt. which is then cleaved at 315-360 degrees over a Ca phosphate catalyst. (I), (II) and (III) are recycled e.g. for synthesis of rubber. The process gives better yields of (I) than single-stage decompsn. over either catalyst alone and fouling of the Ca phosphate catalyst by carbonaceous deposits is avoided.

Title: Refractometer using Fresnel reflection - has additional adjustable lens system with two focal lines for linear characteristic
Inventor: ASSELMEYER FRIEDRICH PROF DR I
IPC: G01N21/43
Filed: 1975-10-28
Abstract: The refractometer operates on the Fresnel reflection principle and has a linear characteristic. Light from the source (1) passed through thermal and colour filters (2), 3) and an iris (4) to a collinator lens (5). The parallel rays fall onto a plane-convex lens (6) placed at an angle to the beam. This produces two focal lines (B1, B2) separated by 90 deg. rotation through astigmatism. Light reflected from the surface of the chamber carrying the material under investigation (12) passes through a grating (18) to a photo-detector (9). Reference light intensity is provided by a partially-reflecting glass sheet (7) and light reflected from this passes to a second photo-detector (10). The electrical outputs of the detectors are processed in the usual way.

No alterations are required in the electric layout of the vehicle and the system is easily fitted to older vehicles. The potential between the battery and the distribution board indicates the amount of current flow. The signal is processed by an Op-amp with adjustment to trim the response to different vehicles.
Patent DE-2606984-A1 (DE)
Title: Printed circuit board contact holes chemically washed - by intense closed circuit spray esp. sulphuric acid and air blowing
Inventor: GEBAUER WOLFGANG
IPC: H05K3/00
Filed: 1976-02-20
Abstract: A method of chemically cleaning the contacting holes of printed circuit boards is carried out with an aggressive acid which dissolves the epoxy resin "lubrication" coatings on the internal face of the walls. The printed circuit board passes horizontally at constant speed, after it has been drilled, into a closed cleaning chamber, in which the cleaning fluid, esp. sulphuric acid, is projected upwards onto its under face from a transverse tube having a longitudinal slit in its upper side; this tube is perpendicular to the direction of travel of the printed circuit board and generally parallel to the board. The sulphuric acid thus flows upwards at high pressure and speed and thoroughly washes out the drilled holes in the board. Pref. conc. sulphuric acid is used and its hygroscopic property ensures that a slight pressure above atmospheric is maintained in the chamber, at low air humidity levels. Reliable and effective cleaning out of the holes results in a min. number of rejected boards. Risk of injury to operators is reduced to a min.

Circular slots around the edges of the discs accommodate flexible, corrugated cable ducts (7) which are snapped into place in the slots. The arrangement makes it possible to insert or remove cables disturbance to neighbouring runs of cable in the same trunking.

Title: Analog PCM converter for telephone exchange - has LF or PAM signals switched to shared A=D converter
Inventor: KUEHNE FRIEDRICH DR ING
IPC: H04J1/04
Filed: 1976-07-30
Abstract: The carrier-wave/PCM converter, for telephone exchanges, has an A/D converter (6) whose sampling frequency (fA) is chosen along with the carrier-wave's (EM) frequency band so that the carrier wave's frequency shift w.r.t. the reference frequency (NF) is an integral multiple of the sampling frequency. The LF signals from the final modulators are passed via switches (5) controlled by the sampling signal to a single A/D converter shared between the channels. A similar arrangement applies if the carrier wave signals are first converted into PAM signals instead of LF signals before being switched to the shared A/D converter.

Title: Paper sheet feed mechanism - has opening in movable wall of vacuum chamber acting against topmost sheet
Inventor: LAMB REGINALD T
IPC: B65H3/08
Filed: 1976-10-22
Abstract: The paper sheet feed mechanism has a vacuum chamber (4) with one or more walls (9) moving freely into a first position nearest the topmost sheet (10) in a stack (7), and in which there is an opening (19). Means are provided for exhausting air from the vauum chamber and for moving the topmost sheet into contact with the wall round the opening, also for sealing the latter off. This gives a pressure difference on oppsoite faces of wall and topmost sheet, so that they are moth moved into a second position by the next sheet on the stack. When the pressure differences reduces by a predetermined amount, the wall returns to the first position when the topmost sheet is removed from the opening. The topmost sheet is thrust in a first direction parallel to the lengthwise axis of the stack by means including a friction surface in the chamber, bearing against the sheet as it is moved into the second position, and which push it into a third position.
