Patent CA-2148173-A1 (CA)
Inventor: KURJAN CHRISTINE M
IPC: A61M5/142
Filed: 1995-04-28
Abstract: The invention pertains to a delivery device for controlling the injection of discrete quantities of fluid injectable materials through a conduit such as a hypodermic needle or a catheter. The delivery device is coupled to a pressurized driving fluid source, and the control means provides controlled passage of pressurized driving fluid into a syringe body to act against a piston which forces the fluid injectable material out the needle or catheter. In addition to the delivery device, the invention includes a needle depth guide which is preferably used in combination with the delivery device for cosmetic applications when a hypodermic needle is used to deliver a fluid injectable material to the dermis.

Title: Process for the elimination of silica and other impurities in fluidized bed syn gas production
Inventor: CLAVENNA LEROY RUSSELL
IPC: C01B3/44
Filed: 1995-08-24
Abstract: A process for the production of syn gas (hydrogen and carbon monoxide) by reaction at high temperature between low molecular weight hydrocarbons, steam and oxygen in an impurities-containing refractory lined reaction zone. The lined reaction zone is pretreated with steam, or with steam and a reducing gas, e.g., a mixture of steam and hydrogen to leach out, react with, and transport the impurities, i.e., the reaction products of silica, or silica plus phosphorus or sulfur, or silica plus phosphorus and sulfur, from the reaction zone. Steam alone may be used to leach out, convert the silica to gaseous silicic acid, and remove same from the reaction zone; and then the hydro-arbons, steam and oxygen feeds are introduced into the reaction zone to produce syn gas.

Title: Circuit interrupter providing protection and waveform capture for harmonic analysis
Inventor: ENGEL JOSEPH CHARLES
IPC: G01R23/20
Filed: 1995-12-21
Abstract: A circuit breaker with a digital trip unit has a protection mode and a waveform capture mode of operation. In the protection mode, an equivalent sampling technique based upon pairs of samples spaced 90 electrical degrees apart with a pattern of delays between pairs is used to digitize the waveforms in the protected electrical system. Synchronous sampling is used in the waveform capture mode. The value of each sample is monitored in the waveform capture mode and a transfer is made back to the protection mode if a threshold value indicating an overcurrent condition is exceeded. The percentage age total harmonic distortion, and per harmonic distortion for harmonics, up to and including the 27th are sequentially presented on a display on the front panel of the circuit breaker and can be transmitted along with the raw waveform data to a remote processor.

Title: An apparatus and process for cyclically accelerating and decelerating a strip of material
Inventor: STUERMER KARL HEINZ
IPC: A61F13/49
Filed: 1994-10-14
Abstract: The present invention discloses a method and apparatus for cyclically accelerating the leading end of a slower moving first material web to match the faster speed of a continuous second material web. The apparatus is comprised of a set of upstream metering rolls which feed the first material web at a constant slow speed, a set of downstream applicator rolls having a constant and relatively faster rotational velocity, and an acceleration mechanism which variably and alternately reverses and allows forward movement of a leading end segment of the first material web while allowing for the constant rotational velocities of the upstream and downstream rolls. The first material web is wrapped partially around the set of upstream rolls and the leading end segment thereof is wrapped partially around one of the downstream rolls. The acceleration mechanism is juxtapositioned between the upstream rolls and the downstream rolls in the feed path of the first material web. A cutting mechanism is provided for cutting a segment of predetermined length of the leading end segment of the first material web when the leading edge has been accelerated to match the speed of the downstream roll. The cut segment is thereafter applied by the applicator roll to the faster moving second material web. Thus, the present invention provides for matched speed cutting and matched speed application of a slower velocity first material onto a faster velocity second substrate material.

Patent CA-2185409-A1 (CA)
Inventor: HSU CHAUR-JIAN
IPC: G01S7/521
Filed: 1996-09-12
Abstract: ABSTRACT An attenuator for use in attenuating tube waves in a borehole includes a body formed from a permeable material having a rigid matrix which can be saturated with fluid. In its simplest form, the attenuator is one or more cylindrical bodies as part of a borehole acoustic logging system. Alternatively, the shape, particularly at the end regions, can be modified to reduce the amount of reflection of tube waves in the borehole. Another attenuator includes a body for placement in a borehole formed from an attenuating material, the shape of the body being selected such that the change in impedance experienced by acoustic waves in the borehole is gradual rather than abrupt. One particularly preferred shape for the body comprises one in which the diameter is greatest towards the center of the body, for example the shape formed by two cones placed base to base, or a cylinder having conically tapered ends. A number of bodies can be used where appropriate.
