Title: Rifle mounted wide or narrow beam illumination or warning unit
Inventor: HUGHES ADAM
IPC: F41G1/35
Filed: 2009-06-12
Abstract: A warning unit (30, fig.1) for attachment to a handheld firearm (fig.1) is disclosed. The unit comprises a laser light source 50 and means (43, 44, fig.2) for manually selecting a beam of narrow divergence or of wide divergence. The unit may be used to illuminate a region within which a target may be located. It may also provide a narrow beam to `trace' a target, for use with guided weapons. In narrow mode, the beam is intended to warn an observer. It is stated that there is no need for the user to remove his hand from the pistol grip of the firearm while interrogating a third party with the use of the warning beam of light. Light levels are controlled to prevent injury to an observer. The light may be modulated. The unit may include a processor to keep records of time, duration and location of use of the warner, to prevent misuse.

Title: Estimating a mud channel transfer function using generated and received telemetry signals
Inventor: HENTATI NABIL
IPC: E21B47/18
Filed: 2005-11-19
Abstract: A characteristic of a communication channel 203 between downhole and surface locations is estimated from a generated mechanical signal 201 and received signal 205. The characteristic may be a transfer function H(f), which is determined by sending a known signal through the channel and spectral analysis of the received signal. The transfer function describes the input-output relationship of the communication system. The generated signal is a stepped frequency signal, which may include three different frequencies. Operating parameters of the system may be adjusted based on the determined transfer function. A computer readable medium comprising instructions that enable a processor to estimate a characteristic of a communication channel is also provided.

IPC: F03G7/08
Filed: 2009-12-03
Abstract: A seal is disclosed for an opening 3 between a movable object 4 and a road surface 5, and for sealing between the road surface 5 and an apparatus 6 below or level with the road surface 5. The seal comprises a first seal 1 with a first elasticity and a second seal 2 with a second elasticity. The first and the second seals 1 and 2 cover the opening 3, with the first seal 1 arranged towards the road surface 5 while the second seal 2 is arranged towards the apparatus 6, and the first elasticity is greater than the second elasticity. The first seal 1 and the second seal 2 are configured to harvest a minimum of energy from any movement of the movable object 4. The first seal 1 may be configured to be subjected to road surface wear. A method of using the seal for avoiding contaminating the apparatus may comprise maintaining the seal by changing the first seal 1 while the second seal 2 is in place.

Title: Torque detection device for battery operated screwdriver
Inventor: HIRT DANIEL
IPC: B25B23/142
Filed: 2009-12-10
Abstract: A torque detection device for detection of torque generated by a power handtool, such as a battery-operated screwdriver, comprises a sensor unit 12 arranged to detect a deformation variable dependent on a deformation induced by the torque. The sensor unit may comprise a strain bar 64, which is subjected to deformation by output torque of a transmission of the handtool, and two strain gauges 16 arranged to detect the deformation. Torque detection is thus achievable without reference to, in particular, the operating current of a motor of the handtool. A transmission element 28 may be provided, such as an internal gearwheel 32, which is operatively connected with a transfer element 30 for transmission of the deformation variable. The transfer element may be of a substantially annular construction, and may have a radial projection 78 for transferring at least one force to the strain bar.

Title: Bucket conveyor and syringe filler
Inventor: CROWE GEORGE
IPC: B65B3/00
Filed: 2009-12-18
Abstract: In an assembly line for loading a pharmaceutical substance in a syringe, a conveyor features a vertical section, thus facilitating the upward transportation of empty syringe tubes using a conveyor with a relatively small footprint. The conveyer features pivotably mounted delivery buckets on a conveyor belt, wherein the delivery buckets can be quickly and efficiently detached using a quick release mechanism. This allows the buckets to be removed and sterilised in a speedy and efficient manner. A guide rail system is also provided to control the pivoting of the delivery buckets along the route of the syringe tube conveyer.

Title: Improvements in the manufacture and production of pure metals
IPC: C21D3/02
Filed: 1930-03-31
Abstract: In the process of purification of impure iron and alloys of iron with metals that form volatile chlorides such as nickel, cobalt, chromium, vanadium and titanium, and silicon by treatment with chlorine, hydrogen chloride or gases containing them at elevated temperatures, for example in a rotary tube furnace, the chlorides are separated from the impurities of the material by volatilization and may be obtained in the case of the alloys, together, or if desired, separately by a fractional volatilization or by volatilizing them together and extracting by means of suitable solvents.  Further purification of the chlorides may take place by redistillation, resublimation, extraction by solvents and reprecipitation, and they may be wholly or partially converted into the corresponding oxide or oxychloride by oxidation or hydrolytic dissociation, for example, by treatment with steam.ALSO:Pure iron is obtained by treating impure iron at elevated temperatures with chlorine or hydrogen chloride or gases containing them, separating the iron chloride formed from impurities by volatilization and reducing it by means of hydrogen if desired after further purification.  The chloride may be completely or partially converted into the corresponding oxide or oxychloride before reduction to metal, by oxidation or hydrolytic dissociation, for example by treating the chloride with steam. The initial materials may comprise instead of iron, impure alloys of iron and metals (including silicon in this term) capable of forming volatile chlorides.  The metal chlorides may be obtained separately by a fractional volatilization or by volatilizing them together and extracting by means of solvents, and reduced to obtain the pure metals.  By not separating the chlorides or by separating them and subsequently bringing them together again after reduction if desired, of one or more of them substantially pure alloys can be obtained. The examples describe the purification of cast iron, ferrochromium containing about 63 per cent of chromium, 29 per cent of iron, and 6-8 per cent of carbon, an alloy containing 73 per cent of iron, 7 per cent of nickel, and 20 per cent of chromium, and ferrosilicon containing 70 per cent of silicon.  The chloridizing may take place in a rotary tube or shaft furnace and the reduction in a tube furnace.

Automatic-feed weighers.-Relates to an automatic-feed weigher having two valves for the main and dribble feeds respectively and a third valve for controlling the outlet of a chamber partitioned off within the supply hopper, and consists in mounting the third valve on the same axis as the two feed-valves but independently thereof. In Fig. 1 the two feed valves 5, 10 pivoted on an axis 14 are shown in the open position. The third valve 6 is shown closing the outlet 15 fcrmed by the presence of a partition 16 within the hopper. A baffle 8 ensures that the chamber 1 is first filled, after which the material flows through a slot 2 and into the weighing-receptacle 3. The descent of the weighing-receptacle releases the valve 5, which falls into the position shown in Fig. 2, an arm 7 on the valve pushing open the valve 6. A dribble feed passes through orifices in the valve 5 and is maintained from the chamber 1 if the former flow is insufficient. When the weight is completed, the gate 10 cuts off the feed in known manner. A baffle 9 ensures freedom of movement to the valve 6.
