Abstract: ABSTRACT            "Method of manufacturing a knife blade"      (Invention by Michel COPPIER) The method of manufacturing the knife blade (1), comprises the following steps.        by stamping the two faces (1a, 1b) of a blade blank (1), a series of protuberances (2, 3) are formed, extending transversely to the length of the blade and, during the same stamping operation, a chamfer is formed on one of the longitudinal edges of the blade, after which, said edge (5) of the blade opposite the chamfer is sharpened.        Use  especially  in order  to  avoid the  blade sticking when cutting food.        (See Figure 1).

Abstract: A pair of truss brackets are secured to the roof of an underground passage adjacent to opposing ribs of the passage.          The truss brackets each include a roof engaging surface and a truss supporting arm member extending from the roof engaging surface.  A pair of U-bolts are supported by the arm members of the truss brackets.  Each arm member extends horizontally from the truss bracket to an enlarged end portion of the arm member.          The U-bolt  is horizontally movable  in a vertically hanging position on the arm member and is restrained by the enlarged end portion from disengagement from the arm member. The U-bolts are pivoted on the truss brackets to a horizontal position for connection to truss members which are connected to each other and tensioned to apply an uplifting force to the roof.  As the truss members are connected and tensioned, the U-bolts are retained for a range of horizontal movement on the arm members to facilitate adjustments in the position of the U-bolts on the truss brackets.

Title: Safety device for a railroad switch
Inventor: RUDERSHAUSEN REINHART
IPC: B61L23/00
Filed: 1993-12-23
Abstract: Abstract of the Disclosure The blade device of the switch of a railroad is able to be locked in mainline position and branch line position by means of a locking mechanism.  The locking state is sensed by means of sensors which activate a safety relay circuit (92) vitally in terms of signaling by means of the contacts (661, 66'2).  This safety relay circuit (92) is of a vital design in terms of signaling and switches by means of control relays (112  114) the signals or train stops arranged ahead of the switch directly to "switch blocked" and/or disconnects safety sectors from the feed unless both sensor establish the locking of the blade device.  Due to the signaling vital driving of the signals, directly by the detection of the locking state of the switch, the driving of the switch does ot have the take place in a signalling vital manner.

Abstract: A telephone advertising service provides a short advertising message through a telephone receiver as a telephone call is initiated.  The advertising message is stopped after a predetermined run time, and an invitation-to-dial tone is added.          The advertising message is stopped when a subscriber starts to dial numbers.  The method provides the advertising messages in lieu of invitation-to-dial tones.  Differentiated subscribers are individually provided with distinct advertising messages.          Subscribers are distinguished by characteristics of exchange number, monthly call volume, call type, geographical location and time of day.  The advertising messages are provided by a message system rack connected to a digital or analog telephone exchange.          Each rack has plural message recorders and plural cards connected to multiple users.  Software controls a connection network.          Subscriber lines are sampled to sense when a call is being initiated and to signal to a controller that a telephone call is being initiated.  A PCM audio interface is activated.  An available message channel is switched to the subscriber line, and a corresponding message is played over the subscriber line.  Soon the subscriber line is connected to the telephone exchange, and an invitation-to-dial tone is provided.  Several different messages are offered in different sets of channels, changing the messages depending on the time of day.  When a prohibit service signal is active, the subscriber line is switched directly to the telephone exchange.

Title: Silica waveguide structure
Inventor: MAXWELL GRAEME D
IPC: G02B6/122
Filed: 1993-02-05
Abstract: A three-dimensional waveguide has path regions which share a common confining region, preferably of uniform refractive index. The path regions are located at two or more levels. The structure is implemented in silica with distributed dopants to distin-guish path regions from the confining region. The structure is made using flame hydrolysis to deposit layers. Melting point de-pressants are incorporated so that later deposited layers can be melted without melting the whole structure. Some layers of pure silica can be deposited by chemical vapour deposition. These layers are never melted and they provide a stabilising skeleton when complicated structures are melted.
