Patent GB-2230725-A (GB)
Title: Lathe with powered cutter
Inventor: WOOD THOMAS WILLIAM
IPC: B23Q11/00
Filed: 1989-04-18
Abstract: The lathe (10) for machining a workpiece e.g. wood comprises a headstock and tailstock for mounting a workpiece for angular movement about an axis (A), a powered cutting tool (25) e.g. a demountable drill or router disposed alongside the workpiece, for producing a cut in the workpiece, the cutting tool (25) being movable bodily longitudinally of said axis (A), and manual drive means (30) for effecting relative movement between the workpiece and the cutting tool body (25). The workpiece station is manually controlled by the same means as the tool movement for synchronisation. Tool position laterally of the work is variable during the longitudinal movement by a template selectively fixed in holes (51). The workpiece station or tool movement transmission can be disconnected selectively from the manual control. <IMAGE>

Patent GB-2218827-A (GB)
Title: Fluid flow control means
Inventor: TASKER RONALD VIVIAN
IPC: F15C1/16
Filed: 1989-05-18
Abstract: To stabilise the flow of fluid through a series of channels (14) supplied in parallel, individual channels or groups of channels of the series are each connected to a separate vortical flow control device. The control devices receive their fluid via tangential, oppositely disposed inlets (28, 30) from respective spaces (10, 20), the fluid in the second space (20) being received from the first space (10) via one or more apertures (21) which results in a lower pressure in the second space. Each device responds to an increase in flow in its associated channel or channels by increasing its resistance to flow, thereby tending to stabilise the flow. The apparatus can be so arranged that there is a stable relationship between pressure drop and mass flow with a considerably smaller energy loss than is dictated by conventional restrictor means employed for the same result. <IMAGE>

Title: Apparatus for mounting an instrument case on a support.
Inventor: TAYLOR PETER
IPC: F16B21/02
Filed: 1992-01-31
Abstract: Apparatus for mounting an instrument case 10 on a support 20 comprises two pairs of legs 14,16 at a front end of the instrument case, and a pair of retaining members 22 and a pair of stressing members 24 on the support 20. The stressing members 24 include a raised surface and a ramp and abutment shoulder on respective sides of the raised surface.

Title: High efficiency low frequency speaker system
Inventor: KLAYMAN ARNOLD I
IPC: H04R1/34
Filed: 1992-05-19
Abstract: A loudspeaker 34, 134 excites a quarter wave resonant air column that is folded forward on itself. The column is closed at one end and has an output located at the other. The output port 20, 120 is in line with the speaker so that the one speaker can excite air both at the output port and at the closed end of the resonant column. At resonance, the column loads the speaker, and the speaker regeneratively drives the column output. At other frequencies output from the port is partially from vibration of the air column and partially from the speaker. At resonance the direct speaker output regeneratively reinforces and combines with the output of the resonant column, which has a length of one-quarter of the wavelength of sound propagated in air at the resonant frequency. <IMAGE>

Title: Abrasive filament honing tool
Inventor: SCHEIDER ALFRED F
IPC: B24D13/10
Filed: 1992-08-17
Abstract: A honing tool 20 comprises an elongated rectangular cup element or holder 44 having a bottom interior surface, a bundle of closely packed relatively short discrete generally parallel filaments 40 secured in the holder, and a thin layer of instant adhesive 46 securing substantially all of the filaments at one end face of the bundle to the bottom interior surface of the holder. To make such a honing tool, a measured bundle of uniformly closely packed nonwoven, generally parallel discrete filaments is formed. A holder is supported and a measured amount of liquid adhesive is placed in the bottom interior of the holder so that a thin layer of such adhesive completely covers the bottom of the interior of the holder. The bundle is then promptly driven into the holder so that all of the filaments at one end of the bundle are in contact with the adhesive prior to the curing of the adhesive. The adhesive is then cured whereby the one end face of the bundle is secured to the bottom interior of the holder. <IMAGE>

Title: Speed estimation
Inventor: CHIA SI TAK STANLEY
IPC: G01S11/02
Filed: 1991-07-25
Abstract: A system and method of speed estimation for a cellular radio network comprises a number of speed estimation units (14-20). Each unit comprises an averaging window (24) of a different duration, a buffer store (26) and variance calculator (28). The duration of each window is equivalent to the time taken by a mobile unit to traverse a distance of 20 wavelengths of the received signal at a particular speed. An incoming signal is applied to the units. The duration of the window determines the significance of the fast fade components in the signal which is related to mobile unit speed. When the average of a window is substantially constant, the speed corresponding to that window can be assumed to be achieved or exceeded. Decision logic (30) is arranged to poll the outputs of the variance calculators to derive a speed estimation indication. <IMAGE>

Title: Electric motor control circuit.
Inventor: YAGUCHI OSAMU
IPC: B60J10/00
Filed: 1993-08-06
Abstract: A circuit (70A) controls power supply to an electric motor (80) and de-energizes the motor when an overload state, indicated by a detected reduction in motor rotational speed, occurs. Rotational speed is monitored by a pulse detector (143) which detects pulses occurring at a motor terminal (T1) due to motor polarity switching. A particular application for the control circuit is driving the motor of an automatic car window, wherein a reduction in motor rotational speed may be due to an object trapped between window and frame during window closure. <IMAGE>
