Title: Acoustic surface wave device - has single crystal element of selected piezoelectric material
IPC: H03H/
Filed: 1974-10-09
Granted: 1978-07-20
Abstract: The single crystal element has a flat surface for propagation of acoustic surface waves which is specially oriented with respect to the element crystallographic axes, and carries interdigital transmitting and receiving electrode matrices, so that a required amplitude-frequency characteristic is obtained; the mass waves are dispersed and/or absorbed. The piezoelectric material and the orientation of the propagation surface and axis with respect to the crystallographic axes is such, that piezoelectric coupling between the above interdigital electrode matrices and at least one of the group of axial mass waves is zero; this group consists of the longitudinal axial mass wave and of one of the two shear mass waves.

Title: Elastic, three-position deck-chair
IPC: A47C/
Filed: 1990-05-15
Granted: 1993-12-17
Abstract: The elastic, three-position deck-chair is made from a special aluminium alloy, consisting of four elements, two external diverging elements and two internal converging elements. The said external divergence and internal convergence - see Fig. 1 and Fig. 2 - enable the elastic chair to assume the correct position before locking it into the desired position by means of the discs - Fig. 4 and Fig.5 of the appended drawing. The novelty of the elastic chair consists in its light weight, which is due to the type of material used, and in the simplicity of the combination used, which does away with the rear or back support present in ordinary deck- chairs, thereby allowing a pleasant rocking motion.

Patent IT-1226673-B (IT)
Title: Gear with continual and automatic variation of transmission ratio
Inventor: PIERANGELO SPILLER
IPC: F16H/
Filed: 1988-08-01
Granted: 1991-01-31
Abstract: The invention concerns construction of a gear with continual and automatic variation of transmission particularly suited to bicycles, comprising a front expandable pulley (2) integral to the hub (3) of the pedals (11) and a rear expandable pulley (4) integral to the hub (7) of the rear wheel (8) connected together by a drive belt (9). Automatic variation is achieved by varying the width of the pulleys (2, 4) and by consequent radial movement of the drive belt along the contact generators, the said variation being obtained through multiple articulated rods (85, 87) that act on the rear mobile semi-pulley (42) and are activated by weights (81, 98) subjected to centrifugal force and through multiple adjustable hubs (23) contrast with the tension generated in the drive belt from the pedals, acting on the front mobile semi-pulley. Hence, by exerting constant torque on the pedals and varying the incline of the road followed, and thus the speed of the bicycle, the transmission ratio is automatically regulated as a consequence, thus permitting torque to be maintained to the pedals without variation.<IMAGE>

IPC: H03K5/153
Filed: 1984-11-23
Abstract: Trilevel sandcastle pulse decoder includes a trio of voltage comparators for comparing incoming sandcastle pulses with reference potentials of respectively different levels. One of the voltage comparators, which is subject to change in operating state in response to appearance of a given level of the sandcastle pulse, is precluded from operating state change in response to the appearance of the next higher level of the sandcastle pulse by control circuitry responsive to the output of a second of the voltage comparators. One of the decoder outputs is developed by logic circuitry responsive to outputs of two of the comparators.

Title: Violin support
Inventor: FORSLUND B
IPC: G10D3/18
Filed: 1980-09-08
Abstract: The present invention is known as a violin support and contains a technical solution for the adaptation of a support to violins of different size. The same support fits sizes 1/2, 3/4, 4/4 and with changing of a rail 5 it can be used for 1/8, 1/4 and various sizes of viola. The support consists of three metal parts of aluminum plate: a first end piece 1 and a second end piece 3 with corresponding extension piece 2 which travels in a rail 5. The first end piece 1 is riveted in the rail 5. As lining, cellular rubber is glued to the surfaces of the support at the extension piece 2 and the rail 5. The foot parts of the end parts grasp the bottom edge of the violin when the support is in place. A linear retrograde motion is produced by a rubber thread 4 fastened in the end pieces 1, 3. For desired straight or slanted placement of the support, the end pieces can be turned into permanent position. This makes it possible to place the support back into the exact same position. For anatomical adaptation to the violinist's shoulder, the extension piece 2 is bendable. <IMAGE>

Abstract: 795,850. Bating leather. ROHM & HAAS GES. Oct. 22, 1956 [Oct. 21, 1955], No. 32143/56. Addition to 776,323. Class 76. Green or soaked hides or skins which have been fleeced or dehaired by the application of enzymic material in the form of a powder as disclosed in the parent Specification are subsequently enzymically bated at a pH of 3-5. Proteolytic enzymes such as pancreatic tryptase, bacterial proteases, or preferably mould fungi tryptases may be employed. By bating at such an acid pH the creation of loose grain produced by proteolytic enzymes acting at an alkaline pH is avoided. The bating lasts from 6 to 36 hours and if necessary may be preceded by a weak enzymic bating at an alkaline pH. In addition to the proteolytic enzymes, mould fungi carbohydrases and/or lipases and advantageously one or more neutral salts such as sodium chloride, ammonium sulphate, or sodium tripolyphosphate may be present. Examples are given of the dehairing by enzymic means and subsequent enxymic bating of: (1) dry goatskins, (2) salted sheepskins, (3) salted calf skins, (4) dry goatskins.
