Title: Method of selecting synchronization pattern from a test signal
Inventor: TIMUS BOGDAN
IPC: H04L7/04
Filed: 1999-06-02
Abstract: A signal quality measurement system includes a transmitter (6) for transmitting a test signal to a receiver and means (20) for storing a copy of the test signal at the receiver. The similarity between said stored copy of the test signal and the signal received at the receiver is measured to determine reception quality. The receiver also includes means (26) for selecting a sequence of different synchronization patterns directly from the stored copy of the test signal, means (30) for determining, from said received signal, a sequence of signal segments that best matches the synchronization pattern sequence and means (30, 32) for synchronizing the received signal with the signal segment sequence, thereby synchronizing the received signal with the stored copy of the test signal.
Patent CA-2334522-A1 (CA)
Inventor: BASQUE ROLAND
IPC: B29C65/22
Filed: 2001-02-08
Abstract: A heat sealing jaw assembly for effecting a heat seal of at least two juxtaposed heat sealable sheet materials is described. Preferably, but not exclusively, the heat sealing jaw assembly is adapted for use in a form, fill and seal machine forming thermoplastic bags. The heat sealing jaw assembly comprises a first and a second metal jaw member, each having a heating element for heating the jaw members. Each of the jaw members has an end face disposed in facial alignment with one another. A ribbon member is secured to each of the end faces and disposed in planar alignment with one another. The ribbon member is made of soft material having rubber-like properties and capable of conducting heat from the sealing jaw to a fusing temperature to melt the heat sealable sheet materials. The first and second jaw members are reciprocatable towards and away from one another to press the aligned heated ribbon members against opposed sides of at least two juxtaposed heat sealable sheet materials disposed between the jaw members to effect a heat seal.

Title: Depilatory paint thickener
Inventor: BUWALDA PIETER LYKLE
IPC: C08L3/12
Filed: 1999-07-19
Abstract: The invention relates to the dehairing or dewooling (depilating) of animal pelts, hides or skins, more specifically to depilatory paint and depilatory paint (depilation paint) thickener used in the depilation process in for example fellmongeries. The invention provides a depilatory paint thickener comprising a starch containing essentially only amylopectin molecules. Such a thickener is among others easily soluble in cold water; improves diffusion o f chemicals (like sulphide or lime) throughout the skin; improves viscosity or  resistance to shear of a paint, whereby less starch is needed to exert a similar effect; and increases the suspendability of a lime, allowing less li me to be used which creates environmental advantages in waste disposal.
Patent CA-2339619-A1 (CA)
Title: Method and coating device for producing a composite glass and biaxially bent composite glass
Inventor: HAVERKAMP ULRICH
IPC: C03C17/00
Filed: 1999-08-04
Abstract: The invention relates to a method and a coating device for the production of a composite glass (1) from a glass element (3) which is at least monoaxially bent and which is coated with a plastic foil (2) at least on one side. The surface of the glass element to be coated is cleaned before being inserted into a calender (20) and conveyed into the calender slot (23). Simultaneously, an adhesive layer (2.2) of the plastic foil is activated and the plastic foil is also conveyed into the calender slot, where it is placed flat on the glass element. The adhesive layer does not slip thereby preventing a relative movement between the glass element and the adhesive layer (2.1) during and after flat application. The glass element coated with the foil is conveyed through the calender and pressurized, wherein the adhesive layer is bonded and permanent connection already occurs in the calender. Since activation of the adhesive, flat application of the foil and bonding of the adhesive are carried out in the absence of water, the edges of the composite element thus produced can be trimmed directly after exiting the calender.

Patent CA-2344631-A1 (CA)
Inventor: ROBIN LAWRENCE E
IPC: E21B7/06
Filed: 2001-04-18
Abstract: An adjustable bent sub assembly is provided comprising a tubular adaptor for connection with the stator of a downhole motor, a tubular adjusting ring for altering the angular offset of the assembly, and a tubular offset sub for connection with the bearing and bit assemblies. A tubular mandrel is positioned internal of this stack of components. The mandrel is threadably connected at its upper end with the adaptor and at its lower end with the offset sub. The mandrel and ring have a spline connection. The ring and offset sub have disengagable dog clutch means connection them. The mandrel is transversely bent at a point along its length as is the offset sub. The ring has an angled or canted bottom end face. The combination of bending the internal mandrel, bending the offset sub and canting the end face of the ring results in the effective or resultant bend point of the assembly being closer to its lower end.

Title: Radio system, antenna arrangement and polarization modulator for generating a transmit signal with changing polarization
Inventor: FISCHER GEORG
IPC: H04B7/10
Filed: 2001-08-30
Abstract: To allow the frequencies available for a radio network to be used more efficiently and consequently the cluster size of a radio network to be reduced, it is known to carry out frequency hopping for traffic channels. Such a process cannot be used, however, for signalling channels, in particular the BCCH channel.      A further improvement in the frequency utilization in a radio network has been achieved by using a radio system with a plurality of base stations (10), which respectively have at least one transmitter (TX) and one receiver (RX1, RX2), each base station (10) being assigned at least one dual-polarized antenna (27). More efficient utilization of the available frequency band, and consequently a reduction in the cluster size, is made possible by the dual-polarized antenna being assigned a polarization modulator (24) for changing at predetermined points in time the polarization state of a transmit signal to be transmitted.
