Title: Acoustic transducers
Inventor: GARNER ALEX VICTOR
IPC: H04R3/14
Filed: 1983-02-10
Abstract: A loudspeaker includes a high frequency transducer 13 and a low frequency transducer 14 mounted on a vertical baffle 12 forming the front of a cabinet 11, and having respective virtual acoustic sources 1 and 3. Each unit receives an amplified signal through an electrical filter to constitute a passive system, and a delay network is included in the path of the amplified signal to the high frequency unit 13 so as to introduce a delay such that the effective virtual acoustic source of the unit is displaced a distance d1 to the right so as to lie in the same vertical plane as the virtual source 3. The acoustic radiation from the two units thus appears to emanate from points in space situated in the same vertical plane, thereby avoiding time delay and phase distortions over the reproduced frequency band. <IMAGE>

Title: Damp proof course
Inventor: GREENUP CHRISTOPHER JOHN
IPC: E04B1/64
Filed: 1983-02-18
Abstract: The mortar of a wall 34 is removed at spaced-apart locations AB, CD. Inflatable, impervious, sealable plastics envelopes 2 having non-inflatable end flaps 12, 14 are inserted into the spaced-apart slots and filled with a quick-setting waterproof mortar which is injected under pressure through valve 16. The mortar BC remaining between the envelopes 2 is removed and an inflatable, impervious, sealable envelope 20, having no end flaps, is inserted into the slots BC and is such that the envelope 20 and the flaps 12, 14 of the adjacent envelopes 2 overlap. The envelopes 20 are filled with a quick-setting waterproof mortar through valves 16 and thus press down tightly on the flaps 12, 14 of adjacent envelopes 2, thus forming a continuous damp-proof course along the wall. The pressurised mortar in the sealable envelopes 2 supports the wall 34 even before the mortar has set and allows the remaining mortar BC to be removed without delay. <IMAGE>

Title: Optical recording head for halftone picture
Inventor: SHIMANO NORIYUKI
IPC: H04N1/036
Filed: 1984-08-02
Abstract: In the production of a halftone picture, electrical signals obtained by photoelectrically scanning an original are processed to obtain picture signals which are used to reproduce the original as a halftone picture. The system includes a recording head 3 comprising 3 LED raws A,B,C, spaced in the main scanning direction.
