Title: Flood protection device
Inventor: KNIGHT MICHAEL
IPC: E04B1/70
Filed: 2009-10-06
Abstract: A flood protection device to prevent floodwater 4 entering an air vent opening 1 in a building comprises an enclosure having an open back sealingly attached to a wall and covers the ventilation opening in the wall to thereby form a duct with the wall and the device. The device has an opening 2 in communication with the duct and the wall opening. The device opening is at a higher position than the wall opening. The seal 3 may be mastic and bonds the device to the wall. The device may be mechanically fixed to the wall with fasteners. The opening in the device may comprise louvers, an overhang or shaped to prevent rainwater or other falling water from entering the device opening. Water may enter the device opening and hence building when floodwater reaches the required height and thus equalises the pressure of water on either side of the wall to prevent structural damage. The distance from the bottom of the wall opening to the lowest opening in the device should not exceed 900mm as pressure from water greater than this may cause structural damage. This distance may be reduced when the device is fitted to weaker structures.

Title: Location monitoring over a period of time
Inventor: MAGNUS EREL
IPC: H04W4/029
Filed: 2009-11-27
Abstract: In a location monitoring device and system a mobile device determines the network area in which the mobile device is located from network address parameters (such as a Cell_ID) in messages sent by the wireless communication network; and accumulates over a period of time data indicating for each network area in which it is determined that the mobile device is located, the corresponding network area parameter and the amount of time spent by the mobile device in that network area over said period of time. A location profile is generated from the accumulated data. This location profile identifies the geographical areas in which the mobile device spends most time. The location profile may be generated either by the mobile device itself, or by a remote network device. A content provider may use the location profiles to target suitable advertisements.

Title: Improvements in or relating to the mounting of polarisation filters on photographic cameras
IPC: G03B17/12
Filed: 1937-04-09
Abstract: 485,802. Photographic cameras with polarization filters. ZEISS IKON AKT.- GES. April 9, 1937, No. 10195. Convention date, April 18, 1936. [Class 98 (i)] Relates to cameras in which the objective is wholly or in part angularly adjustable for focusing, and in which a light-modifying device is so arranged on the camera, if desired detachably, that its angular position with respect to the optical axis is uninfluenced by said focusing adjustment. According to the invention, the light-modifying device is a polarization filter mounted in a carrier in which it can be angularly adjusted about the axis of the objective. The polarization filter may be combined with a colour filter, which may have an absorption band in the region of light arrays not wholly polarized by the polarization filter. Constructions are described in which the carrier of the filter is supported in front of the objective (1) by a lazy-tongs linkage attached to the camera body by a bayonet joint ; or (2) on a member connected to a slide which may be inserted in guides on the folding baseboard of a camera. In a further form, the filter carrier 22, Fig. 5, is supported in front of the objective in a member 19 connected by a universal joint 23 to a slide which may be inserted in the finder bracket 20 on the camera body; and the joint 23 permits the member to be moved into an observation position shown dotted to adjust the filter to its most favourable angular setting. In another form, the filter 15, Fig. 3, is carried by a holder 16 rotatably mounted in a member 11 itself rotatably mounted on the objective through the intermediary of a ball-race 13 ; and the member 11 is eccentrically weighted at 14 so that it does not rotate when the objective is rotated. In all forms, a scale is provided on the filter carrier to indicate the angular adjustment of the filter. Specifications 304,234, [Class 98 (i)], and 373,861 are referred to.

Title: Relay for electric distant control
IPC: G08C19/38
Filed: 1929-04-03
Abstract: 314,374. Granat, E., and Compagnie des Forges et AciÚries de la Marine et d'HomÚcourt. June 26, 1928, [Convention date]. Controlling extent of travel; controlling speed and torque.-In a system of distant control, any number of induction motors repeat, with magnified torque, the rotary movement of a handwheel, through the agency of one or more intermediate machines which are, in effect, constantly running frequency changers. In the arrangement shown in Fig. 1, two induction motors R, designated as receivers repeat the movement of a handwheel 35 through the agency of an intermediate frequency changer A and an exciter E, both A and E being driven by a constantly running motor M. The handwheel is geared to a set of three movable brushes 47 symmetrically disposed over the commutator of the exciter and connected through slip-rings to distributed points of the stator of the machine A. The exciter has also slip-rings 46 through which three-phase current from the rotor is fed to the stators of the receivers, while the threephase rotors of the receivers are fed from the rotor of the machine A. Thus, so long as the brushes 47 are at rest, every receiver remains at rest, since its stator and rotor carry magnetic fields rotating with the same speed in the same direction. When the brushes are rotated the stator field of the machine A is correspondingly rotated and the frequency of the three-phase current fed to the receiver rotor is increased or diminished by a corresponding amount, thus producing the required follow-up torque. The system may be extended by inserting one or more additional intermediate machines similar to A, for the purpose of further power-multiplication. The Specification as open to inspection under Sect. 91 (3) (a) describes an analogous arrangement for receiver motors having a D.C. field fed from mains and a rotor taking distributed threephase current from brushes of a constantly running intermediate machine, the stator of which is fed from rotary brushes on the commutator of a D.C. motor. A further arrangement is described in which a " static transmitter " fed with single-phase A.C. replaces the motor transmitter. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to self-locking screw threaded members
IPC: F16B39/30
Filed: 1952-04-28
Abstract: 742,577. Rolling screw-threads. JEFFCOATE, P. F., and MERIFIELD, W. A. June 20, 1952 [April 28, 1952; May 7, 1952], Nos. 10596/52 and 11505/52. Classes 83 (2) and 83 (4). A die for rolling a self-locking screw-thread on a blank, has on its working face two or more uniform negative threads of the same pitch, one of each adjacent pair of threads being slightly displaced relative to the other of said pair in a direction transverse to the pitch direction of the thread. A die comprises a portion 1 with an extension 1<SP>1</SP> upon which is mounted a sleeve 2, two splines 3<SP>1</SP> on the extension 11 engaging two of a number of recesses in the sleeve. A uniform negative thread is first formed on the external cylindrical surface of the parts 1, 2 and the sleeve is then rotatably repositioned on the splines to displace the thread thereon by the desired amount z, Fig. 1. In a modification the sleeve is splined on an extension 1<SP>1</SP> which is separate from the die portion 1 and the parts 11, 1 are splined to a central shaft, the two sets of splines being differentially spaced. In a further modification, Fig. 6, a platen-die comprises a part 12 held by splines 13 on a member 11 such that after a uniform thread is cut on the working surface of the die the part 12 may be displaced transversely of the member 11. Alternatively the portion 12 may be splined to an intermediate portion which is differentially splined to the extension 11<SP>1</SP> of the member 11. In a further modification, Fig. 8 (not shown), the relative displacement of the portions of the thread on the die is achieved by inserting a spacer between the portions of the die, which spacer does' not project above the thread, and the edge of which is preferably shaped to correspond with the outline of the thread-section at the plane of separation of the die parts.
