Patent CA-2106732-A1 (CA)
Title: Tire Building Drum
Inventor: JELLISON FRANK R
IPC: B29K21/00
Filed: 1993-09-22
Abstract: A tire building drum having a plurality of alternating  wide and  narrow  drum  segments  bearing shells matable to form a cylindrical  tire-building surface includes a shaft and concentric hub rotatable relative  one  another  to  expand  and  collapse  the drum.   In a preferred embodiment, blocks coupled to each respective segment via springs are mounted for bidirectional  radial  movement  in  rotationally-fixed relation to the shaft.  Links nestable when the drum is collapsed connect the blocks with the hub to drive the  blocks  radially  and  function  as  over-center toggles   stabilizing   the   drum   when   expanded.          Variable-engagement slides associated with the blocks most effectively resist non-radial forces exerted by the links when their relative magnitude is greatest.          Dimensional stability and precision of the drum are facilitated by radial and angular stops which are not subject to sliding wear.  Pins of different lengths coupling the wide and narrow drum segments to the blocks  cooperate with  the  springs  to  retract  the narrow drum segments first and by a greater distance when collapsing the drum.  The springs also cooperate with the radial stops by taking up relative movement between  the  blocks  and  drum  segments  to  prevent expansion of the drum at any point during transition to its collapsed condition.

Filed: 1993-10-26
Abstract: ABSTRACT OF THE DISCLOSURE     An abutment area is formed in which two belts 5, 6 are in contact with and  confront each other. Link chains 23 carrying carrier rollers 24 are arranged in  such a manner that carrier rollers 24 are disposed alternately on the back face  of belt 5 and the back face of belt 6, in zigzags. The upper end is connected to winch 25, while the lower end is connected to weight 29. Link chains 23 are wound by winch 25, and link chains 23 are connected to the upper frame 17. When link chains 23 are stretched by weight 29, a force is given to respective belts 5, 6 through carrier rollers 24. Link chains 23 are released from upper frame 17, then  link chains 23 are lowered and folded so that carrier rollers are positioned to  be convenient for maintenance. Corridor for maintenance is unnecessary, and so cost is reduced.

Abstract: A pattern recognition technology includes a set of control signal vector and covariant matrix having respective states of a reference pattern of an objective word for recognition, which reference pattern is expressed by a plurality of states and transitions between the states, and transition probabilities between respective states. A prediction vector of t th feature vector is derived on the basis of the t-1 th feature vector and the control signal vector. A feature vector output probability for outputting the t th feature vector in n th state of the reference pattern of the objective word for recognition is derived from multi-dimensional gaussian distribution determined by the prediction vector and the covariant matrix with taking the prediction vector as an average vector. A word output probability for the reference pattern of the objective word, outputting the feature vector sequence of the input signal employing the feature vector output probability and transition probabilities contained in respective states of the reference pattern, is derived. One of the word output probabilities having the maximum probability as a result of recognition of the word among all of the word output probabilities derived with respect to the objective word is output.

Title: Coin discriminator and acceptor arrangement
Inventor: SHAMES HOWARD
IPC: G07D5/08
Filed: 1995-01-06
Abstract: Discrimination between genuine coins and unacceptable coins (i.e., slugs) deposited in a coin-actuated vending machine, is achieved by guiding a deposited coin for movement along a guide path, and positioning a disk-shaped coil which forms part of an oscillator circuit at a certain position relative to the first guide path such that coins of certain diameters will interact with flux produced by the coil when the latter is excited by the oscillator circuit and the coins are guided in proximity with the coil. Amplitude and frequency values each corresponding to operation of the oscillator circuit (1) in the absence of a proximate coin, and (2) when a deposited coin is at positions along the first guide path which are in proximity with the coil, are measured. Degrees of shift in the amplitude and the frequency values between measurements made at (1) and (2) are then determined. The determined degrees of shift are compared against known shift limits for acceptable (i.e., genuine) coins of interest, and an accept condition for a deposited coin is judged according to the comparison result.
