Abstract: ABSTRACT OF THE DISCLOSURE            Training apparatus is disclosed for training in squash, tennis or other racket sports.  The apparatus pro-vides a new type of training equipment which absorbs the energy of the ball at whatever speed it is hit towards the apparatus and always returns the ball to the player at a con-stant speed.  The apparatus provides a cloth, or similar, which is relatively loosely hung in a frame so that it absorbs the greatest part of a ball's kinetic energy when hit or thrown against the apparatus.  The cloth is sloped at an angle to the horizontal plane so that the ball after contacting the cloth, rolls or falls down along the cloth with a speed quite independent of the ball's impact velocity onto the cloth.  In other embodiments  of the invention, rebound surfaces are pro-vided in appropriate places so that a ball contacts the rebound surface after contacting the cloth, and bounces back to the player.

Abstract: ABSTRACT       In a method and an apparatus for regulating the power which is supplied to a heating element (2) in a water heater (1), preferably a reservoir water heater containing water which is to be heated to a certain temperature, the power which is supplied to the heating element for heating the water, is regulated not only in dependence on the temperature of the water (15), but also in dependence on the temperature of the heating element (2, 4), so that the temperature of the element is kept below a predetermined critical value. The temperature of the heating element is measured directly and/or indirectly, and when the tempera-ture of the element is below the critical value and the temperature of the water in the water heater is below the rated value, maximum power can be supplied to the heating element. When the temperature of the element has reached the critical value, but the temperature of the water in the water heater is still below the rated value, the power is regulated so as to keep the temperature of the heating element below the critical value and to minimize the heating period.

Abstract: Case 3405 COMBINED THERMAL AND ELECTRICAL CUT-OFF DEVICE            Abstract of the Disclosure The device described herein is useful in applications which formerly required both a thermal cut-off device and an electrical fuse.          This device will open an electrical circuit in response to either an increase in ambient temperature or an increase in electrical current.          A bracket is provided to support a radial lead thermal cut-off device.          The bracket is of a general C-shaped configuration and has an extending lead bar that is crimped into electrical engagement with an input lead, and one radial lead of the thermal cut-off device is crimped into electrical engagement with the second input lead. A helical conductive coil has one end welded or otherwise secured to the C-shaped bracket, and the second lead of the thermal cut-off device is crimped to the other end of the helical coil which is positioned over the thermal cut-off device so as to surround it. Thus, an ambient temperature rise may cause the thermal cut-off device to open the electrical circuit; or alternately the heat generated by the I2R loss in the coil due to excessive electrical current flow may cause the device to also open.

Abstract: ABSTRACT OF THE DISCLOSURE         A micro computerized, miniature postage meter comprises an ink jet printing device adapted to project ink droplets onto a document.  A micro computer, which performs the control and data processing functions of the meter, includes a logic circuit programmed to actuate the ink jet printing device to project ink droplets on the document in a postage indicia forming pattern.  In the preferred form of the postage meter, the ink jet printing device is mounted to be moved in close operative proximity relative to the document and the logic circuit is programmed to sequentially actuate the printing device during this relative movement.  The rate of movement of the printing device relative to the document is observed by an optical monitor, mounted with the printing device.  The micro computer also includes a clock circuit, connected to the optical monitor, that computes the instantaneous rate of relative movement of the printing device and document and then generates a feedback signal to the logic circuit to coordinate the instantaneous rate of actuation of the printing device to the computed instantaneous rate of relative printing device-document movement.  A postage memory register stores a purchased amount of postage and is addressable by the logic circuit to reduce the stored amount of postage by the amount printed during each meter use.  A disabling lock-out circuit disables the meter when postage stored in the memory register is depleted to a predetermined minimum amount.

Abstract: 22,492 APPARATUS FOR SIGNALLING SYSTEM          ABSTRACT OF THE DISCLOSURE    Apparatus for a signalling system.  The apparatus includes a plurality of remote control units each of which is arranged to store self-check timing data therein.  This data has a value representing a pre-determined period of time the expiration of which corresponds to a predetermined time of day differing from the times of day associated with at least some of the other remote control units.  At or following this particular time of day, a self-check operation is initiated for communicating a self-check message, including identification number data identifying the remote control unit, to a centralized communications center.  A computer at the communications center receives and processes self-check messages produced by the remote control units and operates in response to each message from a remote control unit to note the identification number data therein and, using this data, to derive self-check timing data for use by the remote control unit in the next self-check operation.          The self-check timing data has a value representing a period of time the expiration of which corresponds to the same time of day at or following which the last self-check operation was initiated by the remote control unit.  The new self-check timing data is com-municated back to the remote control unit for use thereby in initiating the next self-check operation.

Abstract: Abstract of the Disclosure My invention comprises a ballistic impact printer which includes a gun for successively propelling balls to a printing medium spaced from the gun.  The balls are fed to the printer from a reservoir and recycled to the reservoir after they have performed their impact-printing function.          I provide a bleeder duct for the projectiles intermediate the projectile feeder and the gun.  When no printing occurs, the balls are deflected to the bleeder duct and never reach the gun.  When printing is desired, the bleeder duct is blocked in order to constrain the projectiles to be fed to the gun, past a deflector which normally diverts the pro-jectiles to the bleeder duct.  The gate is a rapidly acting, electrically actuated assembly employing a piezo crystal or crystals, an electromagnet, or a solenoid.  The deflector is positioned in the feeding duct and may be spring-loaded so it will yield when the gate is closed.

Power is supplied through a first link from a main drive shaft to a pivoting slider, and then to a rocker arm or a lever which rocks about a pre-selected pivot point.  Power is transmitted from such lever to a rack or other driving mechanism which then supplies motive power to a pinch wheel assembly.  The pivot for the previously mentioned rocker arm is adjustable, and thereby the relative effective lengths of the rocker arm on either side of the pivot may be selectively varied in order to change the extent of rotary movement of the driven pinch roller even through the first drive link continues to travel along a fixed path.

Abstract: ABSTRACT OF THE DISCLOSURE An electrostatic latent image residing on an electrically insulating surface used to induce a similar image on a sectionally conduc-tive member by bringing one surface of the sectionally conductive member into proximity with the latent image while the opposite surface of the sectionally conductive member is brought to ground potential. The sectionally conductive member is then removed from proximity with the latent image. To prevent electrical breakdown during removal, a grounded electrode is placed adjacent the surface of the sectionally conductive member opposite the latent image but separated from the sectionally conductive member by a thin electrically insulating layer. A latent image is thus formed on the sectionally conductive member which can be developed by conventional means such as with electroscopic materials well known in the xerographic art.
