Title: Inflatable buoyancy tanks for boat - has compressed air bottle for tank connected via valve which operates upon capsizing
Inventor: HASSE HERMANN
IPC: B63B43/12
Filed: 1975-06-06
Abstract: The boat or dinghy is fitted with flexible buoyancy tanks which take up a minimum of stowage space when not in use. The tanks are connected to a control valve, via non return valves. The control valve is connected to a compressed air bottle fitted with a pressure gauge to indicate how much air is left in the bottle. If the boat capsizes, or swamps then the operator activates the control valve to inflate the buoyancy tanks. The tanks are protected by pressure relief valves to prevent overinflation. When the boat has been righted the tanks are deflated by release valves, so that they stow away into a small space again.

Title: Nucleosides cleavage - by reacting with acyl halides to eliminate fully acylated sugar residues
Inventor: BERANEK JIRI DIPL ING
IPC: C07H19/16
Filed: 1975-07-10
Abstract: Nucleosides are cleaved by subjecting nucleosides or their acyl derivs. ("acyl" being 2-8C acyl) to the action of acyl halides of the formula RCOX (where R is 1-3C alkyl and X is Cl or Br) so as to bring about elimination of the halide of the fully acylated sugar component. The reaction is pref. carried out at -10 degrees to +50 degrees C (esp. 20 degrees C) in the presence of an anhydrous organic solvent, esp. acetic acid, acetronitrile or benzene. In an example, inosine is reacted with acetyl bromide in acetic acid at room temp. and the reaction product is reacted with silylated uracil in the presence of mercury (II) bromide to give 2',3',5'-tri-O-acetyl-uridine. Production of peracylated sugar halides useful as intermediates for e.g. the prod. of analogues of nucleoside antibiotics or other biologically active substances derived from the sugar components of nucelosides. The reaction is carried out under mild conditions and yields products that are difficult to obtain by conventional procedures.

Title: Motor driven and portable percussive drilling machine - has cams for activating and interrupting percussive movement of drilling shaft
IPC: B23B45/16
Filed: 1975-12-18
Abstract: Motor driven and portable percusive drilling machine includes a disengageable percusive mechanism consisting of a cam body positioned coaxially with drilling shaft in drive housing and a second cam body rigidly attached to the drilling shaft mounted in the drive housing. The cam body of the drilling shaft is engaging the cam body positioned in the drive housing. The cam bodies are during a short relative rotation brought out of engagement and thereby force the drilling shaft to make an intermittent axial movement. The relative rotation of the cam bodies is rendered un-effective by a device activated on the outside of the machine in order to disengage the percusive mechanism. The machine has equipment for holding different attachments on or in the drilling shaft and so to enable its use as a drilling machine or a percusive drilling machine or a screw driving machine or a thread tapping machine.

Title: Spark erosion machine with automatic control - has optical reading head to control cutting tool through electronic circuit
Inventor: WASILIEW WLADIMIR SERGEEWITSCH
IPC: B23Q35/128
Filed: 1976-02-07
Abstract: The spark erosion machine is guided by an optical reading head mounted on a slide which can be moved in two directions by motors. A feed back signal from the reading head is transmitted to the amplifier which transmits corresponding signals to the store and the coincidence circuit. The store also receives signals from the impulse generators and switches. Signals from the coincidence circuit are transmitted through the amplifiers to the motors which guide the tool and to the motors which guide the optical reading head. If the reading head departs from the outline of the template, a signal is generated which corrects the position of the reading head and the tool.
