Abstract: ABSTRACT OF THE DISCLOSURE          Centrifugal blasting apparatus comprising a rotatably supported blasting wheel having a plurality of radially extending impeller blades positioned adjacent the periphery of the wheel.  The blades are relatively short and have their inner ends spaced a uniform and substantial distance short of the axis of rotation of the wheel so as to define an abrasive supply space between the inner ends of the blades.  A tubular member extends into the abrasive supply space for delivering abrasive onto the impeller blades and comprises a main  passageway portion having an axis generally parallel to and spaced radially outwardly from the axis of rotation of the blasting wheel  and a discharge extension on the inner end of the main portion extending radially outwardly and terminating in a discharge opening adjacent to and in a closely spaced relationship with the inner ends of the blades.  Pressurized air propels the abrasive through the tubular member onto the impeller blades.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a spacer clip for an injection molding electric heating element.  A number of clips, each formed of a continuous band, are slipped over one end of the heating element and slid along to predetermined positions.          Each clip is then crimped to the heating element in that position which forms a finger which extends radially from the heating element in a predetermined orientation.  The heating element with the spacer clips attached is located in a suitable mold for casting and the fingers of the clips locate each coil of the element with sufficient clearance from the mold and the other coils.  The thickness of the conductive heater cast around the heating element is important to provide uniform heat transfer.  The spacer clips are formed of a material such as stainless steel which has sufficient pliability to be securely, crimped to the heating element, but sufficient strength to reliably retain the heating element in position.  In one embodiment, the projecting finger may be twisted to give it additional rigidity.  This structure has the advantage over previous spacer plates that no extensive fault lines are formed by the spacer clips.

Abstract: Abstract of the Disclosure An oscillator produces a signal having a frequency equal to a multiple of the turntable speed of a video disc player.  A divider, periodically reset by vertical timing signals produced by the player when in a "play" operating mode, divides the oscillator signal and continuously produces a vertical reference signal equal in phase and frequency to a vertical timing component of the player video output signal.  Synchronism is maintained between the player and a TV receiver when the player is in a "pause" operating mode (when the video output signal is squelched) by supplying the reference signal to the receiver, thereby preventing undesirable "roll" of the image produced by the receiver when the player is returned to the "play" operating mode.

Abstract: ABSTRACT OF THE DISCLOSURE        This invention relates to a register and more specifically to a register control processing system for control.  In general, control registers are theoretically required in such a number less than the number which can be designated (example: 16) and only the required number of registers are mounted as the hardware.  In order to add functions or set compatibility with other system, it is sometime required to use a register not mounted or to use the existing registers for other purposes.  In this case, it can be considered to provide virtual registers on the memory.  But, if only the registers to be added are provided on the memory, instructions must be executed by distinguishing the register access and memory access in accordance with register number etc.          Thus, this invention provides 16 registers as the virtual registers.  The controls are thereby simplified in accordance with a kind of instruction.  Namely, when an instruction is the LOAD instruction, the same content is loaded to both real and virtual registers, or when it is the STORE instruction, content is stored from the virtual register.
