Title: Acrylic! bone cements for surgical applications prepn. - by mixing powdered PMMA with emulsion contg. methyl methacrylate, accelerator and hexa:fatty acid ester of polyoxyethylene sorbitol
Inventor: PIETSCH HANNS DR
IPC: C08K5/092
Filed: 1977-04-07
Abstract: The parent specification describes cement for surgical applications consisting of finely dispersed PMMA in powder or pearl form, contg. a polymerisation initiator and opt. an X-ray contrast material, mixed with a homogeneous aq. emulsion contg. (a) 45-80 wt. % methylmethacrylate monomer, (b) 15-50 wt. % water, (c) 0.5-5 wt. % of an emulsifier, (d) 0.2-5 wt. % of an accelerator and (e) opt. up to 3. wt. % synthetic fibres 3-5 mm long and other additives. In this patent of addn., the emulsifier is a hexafatty acid ester of polyoxyethylene sorbitol. The cements cure rapidly (10 minutes) and are esp. useful as bone cements e.g. for bonding artificial hip- and knee joints to the bone. The named emulsifiers give emulsions with excellent stability. The cements have excellent compatibility with tissue and do not evolve methyl methacrylate monomer after setting, which could cause fat embolism in the cardiocirculatory system.
Patent DE-2719291-A1 (DE)
Inventor: LIN JUEI-PO
IPC: G06F11/14
Filed: 1977-04-29
Abstract: 1536103 Data storage system NCR CORP 29 March 1977 [29 April 1976] 13106/77 Heading G4A A random access store is connected to an output buffer which stores a word from the store and supplies the word to an output respectively in response to input and output clock signals from a clock generator which initiates the output clock signal before termination of the input clock signal. A check device checks the word in buffer for errors at the termination of the output clock signal.  The clock generator may be a counter driven by the clock of an associated processor, the clock of the store output bus, or a clock internal to the store. The store is such that on average data becomes available at a time 30 following initiation of an access at 25, with a variation between time 32 and normally 34 or abnormally even later. The buffer is clocked for input by signal # and for output by signal MGE as shown, the signals terminating together after time 34. Termination of the signals enables a gate receiving the output of a parity check circuit, an error signal from the gate generating a further output clock MGE at the next clock pulse rather than a complete new access cycle. The arrangement allows the store to provide an output at any time during output clock MGE and checks for errors at the end of that signal.

Patent DE-2734744-A1 (DE)
Title: Universal pleat-forming tape for curtains - has fixed connections between draw cord and tape at intervals
Inventor: BUENGER WALDEMAR DR
IPC: A47H13/16
Filed: 1977-08-02
Abstract: The curtain or its support tape (10) is provided with a displaceable fold forming cord (11) bound at the ends of a floating section which corresponds to the length of a group of folds and the curtain or its tape is subsequently firmly connected to the ends of the intermediate section of the cord at spacings corresponding to the required length (16) to obtain the desired group of folds. Since the size of the group of folds can be freely selected the support tape can be individually adapted to any purpose. It is thus only necessary to make a fixed immovable connection between the cord and the support tape at the relevant spacing taken by sewing, welding or gluing. This fixing can also be undertaken by attaching a curtain hook (15) to the curtain wherein the fastening part of this hook can be used for passing through the cord.

Title: Development of electrostatic image - by blowing toner cloud through adjustable length scanning tube assembly and using overall charge potential
Inventor: HEINRICH HANS DIPL PHYS DR
IPC: G03G15/08
Filed: 1977-12-13
Abstract: The latent image in an electrostatic copier is developed by blowing a toner cloud through an electrode system of adjustable length and potential. The toner cloud is blown through a slit which scans the imate. An electrode (29) is sprung against the plate assembly (14) carrying the latent image on a selenium surface (16). The circuit is made through the voltage generator unit (21, 22) and the toner blower (1 to 11). A fan unit (5) creates a toner cloud (8) which is blown through an adjustable tube (27, 10, 28) onto the latent image via a tracking unit with rollers (17, 18) to maintain accurate spacing. The length of the tube unit can be adjusted (23), and this sets the distance between cloud chamber and tracking rollers (17, 18). The cloud chamber (1, 2, 3) is held at earth potential (30') to compte the electrode circuit.

Title: Ultrasonic fresnel lens for medical purposes - can be single or double sided or composite, with liquid filled chamber between halves
Inventor: WESS OTHMAR
IPC: G10K11/30
Filed: 1979-05-12
Abstract: The method of transmitting ultrasonic waves for medical purposes uses a Fresnel lens. This has a series of concentric steps across its face with a convex surface at the centre. The steps are largest near the centre, decreasing in size towards the outside edge. By selecting a stage of a given height, the selected wave is superimposed in the correct phase on the focal point. The Fresnel lens may be a double lens with concentric ring shaped zones or steps, and its spherical abberration is corrected. The angle of the prism between separate zones can be varied between given limiting values. The lens is made of polystyrol. A lens with ring shaped steps on one side only can be used. Two such lenses can be combined, forming an intermediate chamber which is filled with liq. to improve the refractive index.
