Title: Fabricating a double pipe
Inventor: USUI MASAYOSHI
IPC: F01N13/08
Filed: 1989-11-09
Abstract: A method of fabricating a double pipe capable of attenuating vibration when used for example in an automobile exhaust system. A coating made from an epoxy resin, an acrylic resin, or other specified resin, is formed on either or both of the outer surface of an inner pipe 2 and on the inner surface of the outer pipe 1. The inner pipe 2 is inserted into the outer pipe 1, and then they are brought into intimate contact with each other via the coating to couple them together. The coupled pipes 1,2 are heated to above 400 DEG C to leave a loosely packed residue eg. carbon in a uniform gap 3 which results in attenuation of vibration. The pipe 1 may be contracted down onto the inner pipe 2 using a die or the pipe 2 may be expanded into contact with the pipe 1.

Title: Tinting soft hydrogel
Inventor: MATHARU TEJPRAKASH SINGH
IPC: D06P3/34
Filed: 1991-03-22
Abstract: The invention concerns a method of tinting the iris area of a hydrogel soft contact lens (21) to produce a pattern. The area (15) to be tinted is exposed to a vat dye in a predominantly aqueous, liquid, solution through a stencil pattern on a screen (12) so that the dye is absorbed only into the unmasked areas of the lens and the dye is then developed. The screen mask is a flat screen material and during tinting the normally curved lens is adhered to the first side of the screen by surface tension in a flat disposition, with the dye solution applied gently in drops (22) to the other side of the screen, such that the dye is absorbed in a non-solid pattern into the iris area of the lens. The invention is particularly applicable to low (38 % to 50 %) water content lenses.

Patent GB-2259202-A (GB)
Title: Clock synchronization for receiving pulse position encoded signals
Inventor: DEVON MARK
IPC: H04L25/49
Filed: 1992-03-25
Abstract: In a method for clock synchronization for receiving pulse position encoded signals a clock signal defines slots or windows of time in which to receive pulse signals. The signal received within a slot is measured to obtain a value representing the amount of signal received within that slot. The values from adjacent slots are compared to determine into which slot the signal most fully fits, and to determine a clock correction value which would change the phase of the clock to make the slots more accurately center on the received pulses. During a time period in which clock adjustment will not affect received pulses, the clock correction value is applied to the clock. In a preferred form, the measurement of pulses, comparison between slots, and clock correction are all performed digitally. A list of energy values is maintained for all slots within a frame, so that the maximum energy value can be selected for assigning a pulse position to a slot within that frame. Received pulse position modulated pulses at 41, 41' are amplified at 42, 43 and integrated at 44 before being applied to a digital signal processor 48 via a A to D converter 46. DSP 48 controls clock signals for defining the slots. <IMAGE>

IPC: F02M59/26
Filed: 1993-04-07
Abstract: A fuel-injection pump for delivering a quantity of fuel sub-divided into a pre-injection quantity and a main- injection quantity, has an angularly adjustable piston (7) reciprocating in a cylinder sleeve (3) and defining therewith a pump working chamber (11). The piston (7) has an oblique control edge (38) leading to a first annular groove (42) separated from a second annular groove (46) by a land (44). The boundaries of the land (44) form control edges (48, 50) which cooperate with the control edges (32, 30) of a blind bore recess (25) in the sleeve (3). During part of the delivery stroke of the piston (7), a connection is opened between the chamber (11) and a low pressure chamber (19) via the grooves (42, 46). The high fuel pressure in the chamber (11) is thus momentarily relieved. All control edges on the piston (7) are formed as oblique edges to enable the commencement and termination of delivery of the pre-injection process and of the main-injection process to be varied.   <IMAGE>
