Patent DE-2638967-A1 (DE)
Title: Drinking water supply for animal feeder - has container discharging into supply tank and formed with flow control orifices in cap at bottom
Inventor: FUTERS LIONEL HENRY
IPC: A01K5/02
Filed: 1976-08-28
Abstract: The liquid container (1) has an orifice from which the liquid emerges automatically into a supply tank (14). This transfer depends on the drawing of liquid from the supply tank. The supply tank is connected with a drinking vessel. The liquid container (1) has a cap (2) which has holes for the exit of liquid and the inlet of air into the container. The cap dips into the supply tank and the arrangement is such that on achieving a given level in the tank, no more air can pass into the liquid container and no more liquid can leave the liquid container.

Title: Somatic implant for dental- or orthopaedic - surgery - made from monocrystalline sapphire, which is cut to shape and polished
Inventor: HIRABAYASHI MASAYA
IPC: A61F2/00
Filed: 1976-09-16
Abstract: Somatic element or prosthesis, made by the cutting and machining of monocrystalline sapphire ceramic (alpha-alumina or corundum) to obtain the desired shape. The sharp edges, burrs and/or scratches are then removed by polishing, to obtain a bending strength of 9000-20,000 kg/cm2. The element pref. has a blade-, peg- or screw-shape so it can form an endostic implant in dental- or orthopaedic surgery. Polishing pref. consists of (a) chemical polishing at high temp. using molten salt, esp. a borate, molybdate, tungstate, V2O5, lead oxide, Na2CO3 or K2CO3; and/or (b) fire polishing at 1200-1900 degrees C, esp. at 1500-1700 degrees C in a reducing atmos. The element is inert to body tissue and fluids, and is much stronger than polycrystalline alumina due to the absence of grain boundaries; and polishing increases the strength of the implant.

Title: Exercising appts. for physical training - has lever with sliding weight which requires increased effort as mechanical advantage decreases
Inventor: KNOETZE RUBEN
IPC: A63B21/06
Filed: 1977-01-07
Abstract: Physical training appts. has a lever pivoted by a bolt at one end to a rigid support. A weight is suspended by a rod from a tubular fitting which can slide on the lever. A stay consisting of a rod and a tube is connected by a bolt to the connecting piece. The other end of the stay is connected to the rigid support by a bolt. The person using the appts. bends his knees so that his shoulder can be placed underneath the curved extension of the lever. The user then rises up and pushes the lever upwards. This causes the weight to slide towards the curved end and reduce the mechanical advantage of the lever. This means that the effort exerted by the user is correspondingly increased.

Patent DE-2821170-A1 (DE)
Inventor: JACOBY HANS-DIETER DIPL ING DR
IPC: G02B27/32
Filed: 1978-05-13
Abstract: The device for objective target acquisition with the aid of a radial grating evaluates photoelectrically moiré figures which are produced by the superimposition of a target structure image (1) and a measurement structure (4). The modulation which varies with uniform relative motion between the target structure image and measurement structure delivers electrical signals which are proportional to the relative position of the target and measuring structures. Provision is made of two scanning disks (1, 4) with the same radial division, which are used respectively as external target structure and internal measurement structure. Photoelectric receivers (10-13) for detecting the light fluxes modulated by the relative movement between the target structure image and measurement structure are arranged downstream of the measurement structure in the direction of incidence of the light. The electrical signals generated by the photoelectric receivers due to the fluxes they receive are processed in a downstream electronic evaluation circuit (14) to form signals which are proportional to the central deviation between the structures in terms both of magnitude and of direction. The device contains means by the aid of which the deviation is displayed (15) and/or the device is slaved (16) into a desired ideal position between the target structure image and measurement structure. <IMAGE>
