Title: Multi-segment cores for casting engine cylinder blocks - where metal pins are used to hold core segments together
Inventor: SCHEIBNER PETER
IPC: B22C9/10
Filed: 1975-05-17
Abstract: Process for joining multi-segment foundry cores which are hardenable by heating, esp. the assembly of individual cores in the mfr. of engine cylinder blocks, where metal core pins are utilised across the joint lines between the cores, the pins being driven into prepared holes. The novelty is that the metal pins are driven with a force fit into the core immediately after baking while the cores are still hot. A number of pins may be used for each core, at least several pins being driven simultaneously into the cores, the pref. machine including an indexing device which aligns the cores on a stationary plate while nailing machines drive the pins into the cores; the indexing device also deburrs some edges on the cores. The metal pins produce a strong core assembly without using an adhesive, so savings are achieved in time and costs, and the amt. of scrap is reduced.

Title: Magnetic tape recording of digital data - coded in non-return to zero technique available as serial data words for recording
Inventor: NEUMANN DIETRICH
IPC: G11B20/10
Filed: 1975-05-30
Abstract: Magnetic tape recording of digital data which are coded in the non-return to zero technique are available as serial data words for recording. Incoming data are passed to an identification device (2, 3, 6). In dependance on the respective limiting value a signal is produced by the identification device (2, 3, 6) which in order to ensure the recording of the data provides the non-return to zero signal with a limiting value code. Each parallel input of data (lib1 to libn) is connected to an input of adjacent XOR gates in a gate arrangement (2). The outputs are combined to a bus bar and control an inverter (6).

Title: Focal plane shutter with separately driven members - has electronic speed regulators for blinds for fast and accurate movement
Inventor: MIELKE BODO
IPC: G03B9/36
Filed: 1975-06-13
Abstract: An electronic circuit controls the movement of the separate components of a focal plane shutter. The voltage induced in a supplementary winding (25), carried on the blind, is applied to an operational amplifier (29) to regulate the current driving the blind, giving a uniform movement. The other coils (21-23) represent the drive but the method applies to any electrically-driven blind. A switch (27) is the shutter release. The complete circuit consists of two basic circuits including transistors and an operational amplifier together with means for equalising their action, a timing circuit to determine slit width, and an automatic re-set.

Title: Heater for boiling selected quantity of water - has tensioned plunger which actuates water valve for controlled opening and closing
Inventor: KOTSCH HEINZ
IPC: A47J31/40
Filed: 1975-12-10
Abstract: Required water quantity is set by turning a dial, this raises a rod from the zero notch it was resting in, thus tensioning a plunger. When the 'operate' button is pressed, opening the water valve the tension is released and the plunger moves to hold the water valve open and to switch on the heater. The incoming water flows through a geared turbine which, through a train of gears, turns the dial, on which the quantity was set, back towards its zero position. When zero is reached, the rod re-enters its notch, causing the plunger to turn off the heat and to release the 'operate' button, closing the water valve.
Patent DE-2610550-A1 (DE)
Title: Control system for machine tool - calculates reducing increments for successive machining passes
Inventor: TACK ALFRED
IPC: G05B19/416
Filed: 1976-03-12
Abstract: The control device for a machine tool, stores a feed increment to be used for a machining pass, and a modifying constant and then computes the feed increments for a successive pass by forming a predetermined mathematical combination of the stored feed increment and the constant. The device operates iteratively through a sequence as passes. The constant may be subtracted from the increment, in which case the increments form a decreasing arithmetic progression and a plot of cumulative feed against a number of passes becomes a parabolic curve, or alternatively the increment is multiplied the constant, which must, in this case, be less than one, so that the increments form a decreasing exponential progression and a plot of cumulative feed becomes an exponential curve.
Patent DE-2613759-A1 (DE)
Title: Multilayer metal contact for semiconductor module - saves gold and track breaks by successive lacquer mask operations
Inventor: BOTZENHARDT LEONHARD
IPC: H01L21/60
Filed: 1976-03-31
Abstract: The contact is produced by applying a photolacquer mask to metal layers covering the substrate. A galvanically deposited metal layer is partly covered by a second lacquer mask and a mesa structure is produced in a window. Lacquer masks and redundant metal layers are finally removed. In an embodiment the silicon substrate receives a diffused zone through the window of an SiO2 mask. After deposition of a Pt film, turned by tempering into Pt2Si, a Ti-W layer (I) and an Au layer (II) are vapour deposited or sputtered. Another Au layer is deposited galvanically through the window of a photolacquer mask. A window in a second photolacquer mask is used to deposit the mesa structure. In the final operations, the photolacquer layers and the redundant areas of the layers (I, II) are removed by etching. The top gold layer is thus reduced to a min. and all conductor track undercutting by etching operations is eliminated. Conductor track breaks at the edges of vapour-deposited tracks are prevented.

Title: Narrow gauge film cine camera - has viewfinder eyepiece covered with rubber eye cap bending back for spectacle wearer
Inventor: SCHLAGHECK NORBERT PROF
IPC: G03B17/56
Filed: 1976-10-29
Abstract: The cine camera facilities viewing for a user wearing glasses. The eye-piece (7) with viewfinder tube (2) has rubber eye cap (3d). The latter (3d) bends backward when a user with glasses looks through it. Hence, focusing is correct as the distance between eye piece lens (7) and user's eye glass (4) is at a min. and user's eye (5) is at the same distance as for a non-spectacle wearer. The function of part (6, 6a) is to help the user keep a firm support against the user's cheek. If the user does not wear glasses rubber eye cap (3d) will not bend backward and distance between user's eye and eye piece lens (7) will be of correct spacing. When a user does not wear any glasses rubber eye cap (3d) props out and the thickness of part (6, 6a) is exactly equal to length of eye cap (3d) and focusing is easy.
