Patent GB-2146434-A (GB)
Title: Ultrasound measuring instrument
Inventor: KOBLANSKI JOHN N
IPC: G01H3/10
Filed: 1983-09-14
Abstract: An instrument 10 for measuring ultrasound has a first chamber 24 through which sound waves can travel from end to end of the chamber. An acoustic focusing device 50,52 near one end of the chamber concentrates sound waves from an acoustic source 40 at a focal point 56 near the opposite end of the chamber. A rotary shutter 66 is supported within the chamber in a position to be rotated by passage of the concentrated sound waves. Devices capable of transmitting and receiving a ray of light are arranged on the instrument so that the light ray is interrupted by the rotary shutter to provide a series of light pulses. A counter 88 is operatively connected to the light receiving device and the series of light pulses are utilized to actuate the counter and provide a reading indicative of the intensity of the sound waves. The instrument may have an additional indicator of the intensity of the sound waves to supplement the reading provided by the counter. A second chamber 28 is connected to the first chamber by an aperture 47 and absorbs the sound waves to prevent reflection. The instrument may be used to measure the intensity of individual sources or may be used in process control systems (Figs 6,7,8). <IMAGE>

Title: Angling equipment
Inventor: AINSBURY JOHN
IPC: A01K97/10
Filed: 1986-05-15
Abstract: A hook 10 for use as a rest for a fishing rod fits onto ferrule 14 welded to the corner of right-angled bracket 16 that is fastenable to the corner of a fishing basket. The relative height of the hook is adjustable as it is slidable in the ferrule 14 and a wing bolt 20 is provided. Alternatively an E-section plastics hook is held by a cam roller. In use, the height of the hook will be adjusted so that an angler sitting on his basket can rest his rod across his leg above his knee to provide a fulcrum with the hook holding the end of his rod down. This means that the angler can have at least one and possibly both hands free to carry out other tasks. In Figure 89, a V-shaped elongate member 70 has hooks 76 and its angle is adjusted by knob, 74 to provide an adjustable rest. <IMAGE>

Patent GB-2205016-A (GB)
Title: Automatic telephone answering device
Inventor: PARKIN JOHN ROBERT
IPC: H04M1/665
Filed: 1987-03-20
Abstract: Telephones currently have a number of recognised answering tones ie. 'ringing','engaged', 'number disconnected', or 'apparently out of order'. The 'ringing' tone unanswered denotes premises unoccupied and provides a security risk. Consistent non-response to the other tones can cause unnecessary calls to the telephone network maintenance crews. The invention is a generator 'C' of an additional tone which through common usage will signify a specific message, for example 'owner of telephone called does not wish to be disturbed'. The generator is fitted with matching connections to those already provided in most subscribers premises from the telephone network 'A' and to the receiver 'B'. An optional feature is the provision of an 'on/off' switch 'm' which allows the invention to remain plugged in but bypassed allowing use of the telephone in the normal recognised manner. The features of the invention are shown in Drawing 2 of the example above. <IMAGE>
