Title: Arrangement for an axial and radial bearing unit
Inventor: ARVIDSSON THOMAS
IPC: F16C39/04
Filed: 1992-03-26
Abstract: Abstract The present  invention relates to an axial hydrostatic thrust-bearing for an axial and radial bearing unit. This consists of two hydrostatic axial bearings (12, 13) acting on either side of a pressure plate or flange (14) which is connected to the shaft (6). The hydrostatic bearings, each of which  is  equipped with at  least  one  fluid pocket supplied with fluid from an external flow source, exhibit an external form such that, in combination with the bearing housing, they form the hydraulic pressure chambers C and D. These pressure chambers in turn are in direct contact with the pressure chambers A and B of the of the linear servo motor, which in turn are formed by the frame  (1), the bearing housing (2) and a back plate (3). The pressure inside the chambers A and B is regulated via a servo valve (8) in proportion to the externally applied axial loading. In this way the hydrostatic bearings (12, 13) are capable, proportionally to the externally applied axial loading, of absorbing either the whole or parts of same irrespective of its magnitude or direction.

Title: Method and apparatus for opening folded printed products and depositing them on a saddle-type rest
Inventor: HAENSCH EGON
IPC: B65H39/065
Filed: 1992-05-15
Abstract: The conveying device (10) having individually controllable grippers (12) conveys the printed producte (32) in the conveying direction (F) to a straightening station (68) where the printed products (32) are aligned. Subsequently, for opening, the folded print products are fed to an opening device (34) with their open edge (38) leading and are then conveyed further to a transfer region (30), which is spaced apart from the opening device (34), for depositing on the rests (28). The separation of the different functions, i.e. the align-ment, the opening and the depositing of the printed products (32) allows simple setting to different formats of the printed products (32) to be processed. Between the opening device (34) and the transfer region (30), the opened printed products are held open by means of a holding-open device (44).           (Fig. 1)

Abstract: A device for protecting a power supply which is preferable for television receivers, etc. is disclosed.  A diode is connected between a secondary anode of a power supply voltage feedback control photocoupler and a load of the power supply.  When a voltage on the load is lowered due to an abnormality such as short-circuiting of the load, a control current for the power supply voltage feedback control photocoupler flows to the load via that diode to interrupt the control current and stop the operation of the power supply.  Overheating and/or breaking of components due to eddy current can be prevented on occurrences of abnormalities such as short-circuiting.

Patent CA-2088990-A1 (CA)
Title: Chimeric neurotrophic factors
Inventor: SHOOTER ERIC M
IPC: C07K19/00
Filed: 1991-08-07
Abstract: The present invention relates to chimeric neurotrophic factors which comprise at least a portion of a naturally occuring cellular factor and a portion of at least one other molecule such that the resulting chimeric molecule has neurotrophic activity. It is based, in part, on the discovery that chimeric molecules comprising portions of both NGF and BDNF are likely to possess neurotrophic activity, and in some cases exhibit a spectrum of activity larger than that of either parent molecule. It is further based on the discovery that chimeric molecules comprising neurotrophic factor sequences as well as additional peptide sequences may retain neurotrophic activity, and in some cases may exhibit a more potent activity than the parent factor. The chimeric neurotrophic factor molecules of the invention provide a number of advantages relative to naturally occurring neurotrophic factors. Chimeric neurotrophic factors may be used to provide, for example, the activity of two neurotrophic factors in a single molecule, or may serve as superagonists of an endogenous neurotrophic factor, thereby enabling an increased biological response at lower doses.
Patent CA-2095398-A1 (CA)
Inventor: GHOSH KALYAN
IPC: G08B13/26
Filed: 1993-05-03
Abstract: The disclosure relates to a system for the detection of human presence in hazardous situations near moving machinery; appropriately shaped electrodes are placed in an area to be safeguarded and a radio-frequency signal of appropriate frequency and voltage is applied on the electrodes creating an alternating electric field around them. A bridge circuit is used to measure the capacitive impedance created by the electrodes and a dissipation factor is calculated from the real and imaginary parts of the impedance. If a foreign object is introduced into the electric field, the characteristics of the dielectric are modified creating a change of the value of the dissipation factor. The dissipation of energy in the high frequency region is much greater if this foreign object is a biological tissue as compared to other types of materials, such as conductors or insulators. Thus, the system detects human presence by noting the increase of the dissipation factor above a threshold value, and the movement of the appropriate machine part can then be stopped, thereby eliminating the danger of injury to the person.
