Title: Appts. for ion plasma coating of articles - has discharge chamber with slit in one wall to separate the discharge and sputtering zones
Inventor: KOVALSKIJ GEORGIJ ALEKSANDROVI
IPC: H01J37/32
Filed: 1978-01-10
Abstract: Appts. for ion plasma coating has a discharge chamber, contg. an anode and a hot cathode and having a slit in one wall adjacent the hot cathode, arranged in a vacuum chamber together with a target to be subjected to sputtering, and a holder, for articles to be coated. The target and article holder are arranged in the vacuum chamber on both sides of the plasma flow. A magnetic field is produced to extend through the hot cathode and slit in the discharge chamber wall at a perpendicular to the electric field between the hot cathode and anode. Used in applying thin films of metals, semiconductors, and dielectric materials, onto surfaces of different articles. Placing the cathode and anode in a closed discharge chamber with a slit having a certain gas conductivity makes it possible to separate the discharge and sputtering zones providing optimum pressure conditions to maintain the discharge and ensure high quality film to be produced.

Title: Container for domestic washing machine soaps - is flexible, changing volume as fluids are sucked out by pump
Inventor: SCHROTT HUGO
IPC: D06F39/02
Filed: 1978-02-04
Abstract: A device for fitting to domestic linen and dish washing machines, for the dosing of the detergent fluids, overcomes the problems arising from contact with the air. In conventional containers a film tends to form and dry out into a tough adhesive layer. Device consists of a replaceable flexible container which alters its volume as the fluid from which air is excluded, is sucked out. An additional advantage is that a pressure sensitive device can be fitted which puts out a signal when the container is empty.

Title: Pen or pencil with built-in letter opener - has pointed finger carrying sharp blade screened by cap of pen
Inventor: BOSSHOLD BARRY L
IPC: B26B27/00
Filed: 1978-03-09
Abstract: Secured within the cap of the pen etc. is the letter opener (18) which includes an elongated finger (20) the distal end of which (22) is pointed enough to enable it to be inserted into the small loop that is formed between a folded paper, e.g. under the flap of a conventional envelope. Carried on the finger to extend upward is a razor sharp blade (24) which will slice through the top of the flap. Pref., the blade extends completely across the space between the finger and an overlying hood portion (26). When the letter opener is in place in the cap of the pen (10) the finger (20) is exposed through an opening (27) which is provided in the cap (28), and extends at least as far back as the cutting blade (24). Hence, the cap (28) forms a shield or hood extension which embraces the blade and finger on both sides, leaving an opening between its depending sides (30) and (31) and the finger which is too small to permit entry of a human finger.

Title: Sunshade roller or folding window blinds - with absorbent coating for heat recovery, used e.g. between the two window panes in double glazing
Inventor: KOESTER HELMUT DIPL ING
IPC: F24J2/04
Filed: 1978-09-14
Abstract: Roller or folding types of window blinds are used for the recovery of solar heating energy by arranging them on brackets which can be turned to create a wide space against the glass. The material for the blinds can be a plastic foil with an aluminium coating (by vapour deposition) for radiation reflection at the rear and an absorbent coating on the incident side. The heat, produced in the space between blind and glass, is removed by convection or by forced ventilation. This system combines the two functions of protection against direct solar radiation with a recovery of the solar energy for room heating.

Title: Operational amplifier power supply circuit - arranged to bias supply voltage in sense to give highest amplifier gain
Inventor: GLAS JOSE
IPC: H03F1/02
Filed: 1979-06-12
Abstract: The object of the circuit is to modify the power supply voltage level to an operational amplifier in order to fully utilise the available amplification capability. The power supply for the operational amplifier (OV) is taken from between earth and one pole (-48V) of a general supply. Between each pole of the supply and the amplifier power supply terminals (E1,E2) is a transistor (T1,T2) whose base in each case is connected to the amplifier output (A1), and, through a resistor (R2,R3) to the corresponding supply pole (earth, -48V). A zener diode (Z1,Z2) is pref. connected between each transistor base and the amplifier output. The amplifier input is connected to the inverting terminal. The resulting output then biases the power supply such that the maximum voltage is available at the output to the load (B).
