Title: Insertable vortex induction flowmeter - comprises obstacle fitted inside tube which is clamped into pipe system and connected to pressure tappings
IPC: G01F1/32
Filed: 1975-03-17
Abstract: The insertable vortex induction flowmeter, for use in either liquid or gaseous flows, comprises an obstacle (11) mounted inside a tube (10) which is placed between the front and rear (13) parts of a pipe system. The internal diameter (d) of the tube is less than the diameter (D) of the front, or upstream, part of the pipe system (13), and is uniform along its length. The inlet and outlet ends (10A, 10B) of the tube (10) are rounded off in order to make transitions between the tube (10) and the pipe (13) more regular. The obstacle (11) is positioned at the mid-point of the tube (10). The flowmeter is clamped or flange-mounted to the pipe system. In alternative arrangement, the tube may be conical with the smaller diameter at its inlet and the obstacle positioned near the inlet.

Abstract: A holding mechanism for holding ski boots onto a ski. The holding mechanism is comprised of a longitudinally extending rod extending parallel to the longitudinal axis of the sole of a ski boot and has at least one crossbar thereon with conventional elements for engaging and holding the boot to the crossbar. The longitudinal rod is secured at one of its ends to a holding element secured to the ski.

Title: Drilling device for large holes in sheet metal - consists of a drum in which a gear driven cutter is mounted
IPC: B23B51/05
Filed: 1975-03-27
Abstract: A central shaft is mounted in the drum which is secured by means of a flange to the top face of the drum. This flange is integral with a hub keyed to the central shaft and provided with external thread. A pressure ring is screwed on to this hub. The pressure ring has an external gear ring which engages with a pinion. The pinion can be rotated by hand via a handle, this will make the pressure ring screw down the hub. A gear driven hub on which a cutter is mounted is located directly underneath the pressure ring. The cutter is driven via a gear train by a power tool which is mounted on a shaft which protrudes from the drum. The central shaft protrudes from the bottom of the drum and is mounted in a pilot hole in the sheet metal to be cut. The drum can be clamped on the sheet to be cut with a clamping disc. The cutter is screwed into the sheet to be cut by means of the handle and the pressure ring.

Title: Switched voltage transformer - has multitapped primary and switching occurs with no volts across the switch terminals
IPC: H01F29/02
Filed: 1975-06-16
Abstract: A switched transformer is used to provide a variable a.c. output from a constant a.c. input. The design is intended to act as a autotransformer minimising the volts per turn by having a switch arrangement across the contacts of which there is no voltage at the time of operation. The transformer has a single winding (1) across which the input supply (2a, 2b) is connected, Tappings (3a to 3n) are included in the winding at regular intervals, the winding length between such tappings providing a comparatively low voltage. Each tapping can be included in the output circuit by mechanical or static switches (4a to 4n). Alternate switches leading to the terminals of an orthodox output autotransformer (6).

Title: Submarine location pod handling and towing mechanism - support formed by two sets of articulated levers mounted at spaced locations on winch frame
IPC: B64D3/00
Filed: 1975-06-25
Abstract: The mechanism lowers, tows and raises a vessel for a submarine location pod lowered from a helicopter. When the body is wound right in it is supported in a cradle on the helicopter by a set of articulated levers when these are folded, or solely by the rope when the levers are unfolded. There are two sets of such levers with homologous ends pivoting at points spaced apart on the winch frame, and preferably at the same level. Their other ends pivot on a horizontal junction bar, the length between the pivot points on it being preferably the same as between the pivot points at the other end. The bar supports the cradle proper below it. The overall height of the set of levers when unfolded is great enough for the junction bar to be in a zone free of air turbulence induced by the helicopter rotor.

Title: Connection hunting system for telephone exchange - gives chatter-free test contact operation by delaying busy current using RC circuit
IPC: H04Q3/00
Filed: 1976-03-19
Abstract: The connections hunting system, for telephone exchanges, has the current rise in the busy circuit delayed to allow chatter-free contact operation. A resistor is connected in series with a transistor limiting the busy current. The voltage on the transistor's base is determined by an RC timing circuit which turns the transistor on after a given charging time starting at the beginning of a test/busy process. The RC circuit's resistor carries the current for the capacitors charge stage change and for the transistor's base circuit. The arrangement briefly delays the current rise by means other than inductive components for example relays.

Title: Pyrometer probe giving rapid response - incorporates fine platinum wire wound on ceramic base sheathed in stainless steel
IPC: G01K7/18
Filed: 1976-06-02
Abstract: A pyrometer probe, for measuring the temp. of water in the primary circuits of nuclear reactors or other applications where a rapid response is necessary, consists of a winding of very fine platinum wire on a ceramic base with a coating of stainless steel and a third compensating wire. The probe is housed in a perforated stainless steel tube. Pref. the housing includes shock resistant isothermic siliconised glass wool protective packing. The device does not have the inconveniences of existing probes, which transmit several minutes after the temp. change. It allows continuous and instantaneous following of the temp. changes in e.g. the primary circuits of nuclear reactors, where response time and the reliability are very important. The mounting of the sensitive element gives perfect holding against vibrations.

Title: Remote control system using telephone link - uses telephone call bell for providing audible control signal
IPC: H04M11/00
Filed: 1976-12-06
Abstract: The remote control system uses a telephone link e.g. for actuating a domestic central heating system. It uses the telephone call bell to convert incoming pulses into a pulsed audible control signal. Logic systems monitor the initial number of audible pulses, to prime the control system and the control cunction is determined by a following series of audible pulses, together with the interval between the two sets of pulses. The initial group of audible pulses has a number of pulses denoting the required control function, the following group of audible pulses having a number of pulses which is a given multiple of this number.
Patent FR-2336806-A1 (FR)
IPC: H03H9/10
Filed: 1976-12-22
Abstract: A vibrator unit for use in a timepiece comprises a vibrator mounted within a ceramic case. A glass lid is airtightly sealed to the ceramic case by means of a soldering washer soldered between opposing surface portions of the lid and case. The soldering washer consists essentially of 90Sn-10Au solder alloy which enables formation of the airtight seal at lower and/or shorter soldering temperatures than would be the case with conventional solder alloys thereby avoiding an increase in the equivalent impedance of the vibrator unit which would otherwise occur. As the equivalent impedance can be maintained at a low value, the vibrator unit can therefore be made smaller without adversely affecting the equivalent impedance which is maintained below 350 K OMEGA .
