Abstract: An amusement device for use by children both for enter- tainmentas well as a coordination aid. The device comprises a plurality of thin essentially similar segments (10), each segment pivotally engaging adjacent segments in snap-in relation (12). The pivotal engagement enables rotation of one segment (10) with respect to an adjacently engaged segment (10) through a predetermined angle. Locking means are formed into the segments (10), preventing translation of one segment (10) with respect to another when such segments (10) are engaged. When connected in the form of an open belt, the device may be manipulated in various entertaining manners, and upon articulation, the impact of adjacent segments (10) produces a slapping sound for additional amusement. When the free ends of the belt arrangement are engaged to form a closed loop, two segment stacks (16, 18) are created. Back-and-forth manipulation of each segment stack causes individual segments (10) to move from one stack (16,. 18) to the other. Additionally, by providing indicia such as pictures, performations, and patterns on each segment face, a changing visual display is obtained as the segments (10) are articulated from one stack (16, 18) to the other.

Abstract: Apparatus is described for producing hard copy prints of images displayed on a raster-scanned CRT terminal. A row of light-fibres 4 are attached to a preselected scan line of the CRT 3 located behind the CRT bezel 5. The other ends of the row of light fibres 4 are located along the surface of a print roller on which light sensitive paper 6 is supported. A light pattern produced as a result of an image scan along the preselected scan line is transmitted by the light fibres to the paper 6 which is exposed to form a latent image of the light pattern in a print row on the paper. In order to print a complete image, the paper is drawn past the print row and exposed successively to each raster scan row of the image to be printed. The exposed paper is then passed through a developing station 10 where the latent image is developed by heat. Two modes of operation are described. In one mode the image display is interrupted during the print cycle, in the other mode both display and printing are performed concurrently.

Abstract: A two-stage system for enhancing the imaging uniform<sup>i</sup>ty of a scintillation camera detects radiation events and produces radiation count signals indicating the location and energy level of individual detected radiation events. The uniformity correction system compensates for imprecision in the camera's indication of both radiation event location and energy level. Compensation for energy indication errors is done by a first stage, prior to a second stage correction for errors in event location indications. The operations of both stages are carried out in real time for each individual radiation count, independently of the production of other counts. The first stage locates and stores the peak of detected energy pulse height distribution for each of a plurality of regions in the camera's field of view. This regional profile of the camera's energy response characteristic is used to synchronously align a pulse height energy window of the camera imaging circuitry with a series of pulse height distribution peaks respectively corresponding to the regional locations of each of a series of radiation counts. The second uniformity correction stage, a flood correction circuit, produces and stores a profile of the camera's regional variations in sensitivity in response to uniform radiation flux over its field. This stored information is used for calculating sensitivity correction factors for several regions of the field. The correction factors are used for controlling the ratio of radiation counts corresponding to each region which are actually imaged, thus effectively equalizing camera sensitivity over its field.

Abstract: In extrusion blowing a hollow member, a preform is extruded and then blown in a mold to produce the final member. The weight of the hollow member is determined after its removal from the mold and compared to a reference value, thereby to adjust the size of the extrusion discharge opening to control the amount of material in the preform. The length of the preform is detected to control the movement of the mold thereby to keep a substantially constant length of extruded preform, while the time required to produce a preform is also maintained at a substantially constant value.

Abstract: A minute opening 3 min  is formed in a negative resist film 4 by exposing the film 4 through a mask 2 having opaque parts providing a real pattern 3 corresponding to opening 3 min , and false patterns 7 proximate to the real pattern 3. The false patterns 7 are of a width such that the photoresist film 4 below those patterns has unexposed parts 8 extending only part way through the thickness of film 4. During developing the unexposed parts 8 provide for take-up of swelling of the resist, to prevent obliteration of opening 3 min . No openings appear in the resist film 4 corresponding to the false patterns 7. 
<??>Alternatively, below false patterns 7 the resist film 4 may exposed throughout its depth, provided the width of the false patterns 7 is such that swelling of the resist during developing still ensures that no openings appear in the resist film corresponding to the false patterns.
