Title: Glass aquarium with at least one curved side - has all-glass surfaces bonded together without reinforcement
IPC: A01K63/00
Filed: 1973-09-12
Abstract: The purpose of the invention is to eliminate the use of angle brackets to join the glass sides, lowering costs and adding to the aesthetic value of the tank. The glass sides can either be bonded edge to edge or cut away to form mitre joints intended to receive a fillet of adhesive. Such an aquarium could be composed of two opposite convex sides (11 & 12) and a floor (1) bonded to each other with adhesive. Two compartments (2 & 3) to house filter pumps and other accessories could be attached to each end of the tank in a similar fashion. The whole could then be fitted with a cover (C) and lamp supports (4). Concave sides are preferred for long rectangular tanks since they are stronger.

Title: Fluid filled acceleration detector - has mass held below threshold value in housing with detector at end
Inventor: MARTIN FREDERIC
IPC: G01P15/135
Filed: 1974-07-31
Abstract: The detector comprises a mass (1) freely mounted in a housing (2) elongated in the sensitive direction, parallel to the direction in which speed variations are to be measured. The housing (2) is sealed and filled with a fluid. The mass is held immobile in its housing until the acceleration exceeds a threshold value. The impact of the mass at the end of the housing is detected (4). A deformable wall may link the body of the housing to a component which carries the retention means and/or the detector, this component being mobile along the sensing axis. The viscous forces during movement of the mass are much greater than the forces acting on the mass due to speed variations.

Title: Loom has warp divided into two sections - so that beating up of weft in one section occurs during picking of weft in other section
IPC: D03D41/00
Filed: 1974-07-31
Abstract: A loom has the warp divided into two sections so that after picking of a weft yarn from one side of the warp in the form of e.g. a loop has been effected in the first section of the warp, the shed of this first sectionis closed and the weft yarn beaten up whilst picking of the weft yanr in the second section of the warp is effected. Beating up of ht weft yanr is effected in the second section of the warp during subsequent picking of the weft yarn in the first section of the warp. The arrangement is simple and speeds up the weaving process. Pref. the time at which the sheds of the two sections are open together forms a relatively large proportion of the weaving cycle. Pref. the time during which need is at rest during picking of the weft yarn is greater than the time that they are at rest after the completion of a weaving cycle.

Title: Fusion-welded zones with improved quality - obtd by remelting with a reciprocating arc burner
IPC: C23C4/18
Filed: 1974-09-16
Abstract: In a process for improving the quality of the heat-affected zone on fusion-welded surfaces, esp. steel structural elements welded by hot-wire plasma welding or powder-elements welded by hot-wire plasma welding or powder-welding with Ni alloy or Cr/Ni steel strip electrodes, an arc burner with a non-consumable electrode, the energy of which is sufficient to melt only part of the weld layer, is moved to and fro over the surface of the weld in such a way that its rate of progress along the weld divided by the frequency of its to-and-fro motion is less than the max. dia. of the arc (no units specified). Surface remelting carried out in this manner eliminates cracks in the heat-affected zone caused by the original welding.

Title: Transparent panel with good heat and sound insulation - has two panels separated by low pressure space with spacers and edge seal
IPC: E06B3/66
Filed: 1974-12-09
Abstract: A transparent panel with good heat and sound insulating properties which can be mounted in either a wooden or a metal frame comprises two sheets of glass linked by an air and water-tight joint.

Title: Read signal equalization or compensation network - removes derivative function of head and corrects high frequency roll off and phase distortion
Inventor: SCHNEIDER RICHARD C
IPC: G11B5/035
Filed: 1975-04-16
Abstract: The derivative function performed by the magnetic read head is compensated by an integration function. The high frequency roll-off and phase distortion is compensated by a series of circuits having in LaPlace transforms a transfer function of the form (1+AS) (1-BS) where A and B are constants, and S is the frequency variable jw. Phase distortion in the read signal appears in the form of asymmetrical pulses. constant A and B in the above transfer function may be varied by varying circuit components in the equalization network to eliminate the asymmetry in the read signal. In particular, the function (1+AS) may be used to shape the trailing edge of the read signal pulse, while the function (1-BS) may be used to shape the leading edge of the read signal pulse.

Title: Hydropneumatic shock absorber with two pneumatic chambers - has floating piston to avoid excessive gas pressure when fully compressed
IPC: F16F9/06
Filed: 1975-04-23
Abstract: A hydro-pneumatic shock absorber consists of a cylinder (1) a piston rod (2) and a piston assembly (16). A floating piston (5) divides the shock absorber into a hydraulic and pneumatic section. A hydraulic chamber is located on either side of the piston assembly (6) and they are connected with one another by throttle elements (6a-6c) inside piston (6). The pneumatic chambers (C, D) are formed by the space between the floating piston (5) and the cylinder end, and by a concentric tube (7) which forms a ring chamber on the outside of the cylinder. The two communicating pneumatic chambers provide thus a large enough gas volume to prevent excessive pressure when the shock absorber is fully compressed.
