Title: Card game
IPC: A63F3/00
Filed: 1979-08-28
Abstract: A pack of cards represents musical notes and rests (Figures 1 - 13), having time lengths which are multiples and sub-multiples of each other. To play a game, a series of spaced parallel markers representing bar lines are laid out, and the cards are laid between them in turn so as to form bars of music in accordance with the rules of musical notation. The most important of these rules is that the total combined time value of cards in each bar should be the same. Cards representing time signatures (Figures 14 - 15) are also provided, and further cards (Figures 16 - 26) represent other musical symbols to indicate variations in the ordinary course of play. The cards are marked with coloured bands A to facilitate sorting out those cards required for different versions of the game. <IMAGE>

Title: Drilling boreholes
IPC: E21B47/00
Filed: 1980-01-23
Abstract: An apparatus is described whereby the side force on a drill bit can be measured during drilling operations and transmitted to the surface where it can be used in predicting trajectory of the hole and taking corrective action in the drilling operation. A downhole assembly using a downhole motor is modified to include means to detect the side thrust or force on a bit driven by the motor and the force on the deflection means of the downhole motor. These measured forces are transmitted to the surface of the earth during drilling operations and are used in evaluating and controlling drilling operations. Means are also provided to measure magnitude of the force on a downhole stabilizer.

Title: Signal rank detectors
IPC: G01S7/292
Filed: 1980-03-24
Abstract: A signal rank detector for use with a CFAR radar receiver consists of two stages, each having a serial shift register 34 and 46 respectively. The first stage compares each received amplitude sample (in cell 16) of a radar video signal with preceding and following samples to establish the rank of the sample. If the rank (output of 37) exceeds a first relatively low threshold value 40, a rank signal 41 is generated and the results of the comparisons are passed together with the rank signal to the second stage so as to enable a final output rank signal using a relatively high threshold signal value 51 to be produced. The detector enables weak target signals to be accepted even if a stronger target signal is also present, but without increasing the response of the detector to unwanted noise signals. For a lower rank echo sample, eg the third highest in each of three consecutive p.r.p's (p.r.p delays 45, 43), in cell 16 of register 46, there will be only three other cells of 46 having a 1 state (threshold value 40 is for the top four ranks). The majority of the first stage comparator outputs X will however be 1 states, and via gates 47 these will sum with cell states to high threshold value 51. <IMAGE>

Title: Water-soluble casting core
IPC: B22C9/10
Filed: 1981-03-09
Abstract: A core for use in investment casting comprises a ceramic material and a binder such as sodium aluminate which is soluble in water and stable up to such temperatures that the core is refractory above 800 DEG C. Such a core is manufactured by forming the mix of the ceramic material and binder into a granulated semi-dry powder which is then pressed in a die from which it is removed and dried and then fired before use. Alternatively the ceramic material and binder are mixed with an additional organic binder with the resultant mix being granulated and injected under pressure into a die. After removal from the die the core is fired to burn out the organic binder. When such cores are used they can be leached out after casting with a hot solution of dilute boric acid or other weak acid which acts to neutralise any sodium hydroxide formed.
