Title: Waste pulpers
IPC: D21B1/34
Filed: 1978-10-12
Abstract: A pulper for pulping waste material of the type comprising a body (34) and an abrading disc (37) therein driven by an electric motor (39) to effect abrasion of waste material in contact with the disc (37), is characterised by supplementary abrading means (31, 32) in spaced opposed disposition relative to the disc (37) and positioned to contact and abrade buoyant waste material supported on the vortex created by the rotating disc (37). The supplementary abrading means (31, 32) may be a second abrading disc (31) rotatably driven by the motor (39) or a separate motor (33) and mounted in an inclined sidewall (35) of the body (34). Alternatively or additionally the supplementary abrading means may be a fixed, preferably frusto-conical surface of the body (34). <IMAGE>

Patent GB-2008675-A (GB)
Title: Fuel Injection Systems for I.C. Engines
IPC: F02M69/44
Filed: 1978-12-04
Abstract: The quantity of fuel injected into the engine intake manifold is automatically regulated to match the quantity of air entering the engine air intake. A feed pump 16 delivers fuel at constant pressure via a flow control valve 19 to one end of the cylinder 21 of a hydraulic plunger, and the fuel injection pump 13 draws fuel from the same end of the cylinder. The plunger rod 26 of the cylinder is coupled to the stroke control member 14 of the injection pump. The valve 19 is coupled to an auxiliary butterfly valve 31, upstream of the main throttle valve 30, the valve 31 being controlled by an aneroid device 32, so that the fuel flow rate into the cylinder 21 is regulated in accordance with the mass air flow rate into the air intake, and the difference between the fuel flow rate into the cylinder 21 and the fuel demand by the injection pump moves the plunger piston 22 to regulate the stroke length of the injection pump 13 in the sense to reduce that difference to zero. Since the injection pump 13 is engine- driven, its overall fuel delivery rate is then controlled automatically in dependence on the air intake of the engine. Overriding controls (41 and 51), Fig.2 (not shown), may be provided for increasing the fuel delivery on cold starting and for acceleration. <IMAGE>

Title: Work holder assembly for a lathe
IPC: B23B31/40
Filed: 1978-12-19
Abstract: Means for dressing a work piece in a lathe having a rotary driven shaft (24) includes a work holder assembly (10) adapted to hold a drum or disc (21) in position for dressing a cylindrical face or a circular end face. The work holder assembly includes adapter members (12, 16) preferably formed with frusto-conical faces for engaging a drum therebetween or for engaging in a central hole of a disc. A rigid circular plate (36) has spaced threaded adjustable bolts (40) bearing on the disc or an end wall of of the drum. Spacer members (44a,b,c,d) bear against the circular plate via a bolt (43) received in an end on the rotary driven shaft (24) to retain the adapter members, plate, and spacer members in axial alignment on the shaft. The rigid plate and adjustment bolts hold the work piece in axial alignment with the shaft, and correct distortion in the disc or end wall of the drum. They also prevent vibration of the work piece during dressing. <IMAGE>

Title: Process for the production of solid sterilized packages textured vegetable protein products simulating solidified products
IPC: A23J3/22
Filed: 1979-03-22
Abstract: This invention concerns a process for the production of solid sterilized packaged textured vegetable protein products simulating solidified products and is especially applicable to a product simulating pork luncheon meat. The vegetable protein is usually a soya protein of particle size 4.75-8 mm which is soaked in water at ambient temperature for 18 hours under controlled conditions so that the water intake is limited to be less than the theoretical water intake of the protein. Thus the water absorption of the protein is controlled to be within the range 250 - 270% of the unhydrated weight of the textured soya protein and the pH of the water employed is monitored to ensure that it does not exceed 8.5. The hydrated soya protein is then drained and combined with vegetable or animal fat having a slip point greater then 25 DEG C but not greater then 30 DEG C together with a combination of hydrocolloidal edible gums and additional water prior to the product being comminuted and filled into cans which are sterilized and sealed.
Patent GB-2019268-A (GB)
Title: A machine-tool spindle and bearing assembly
IPC: B23Q5/06
Filed: 1979-03-27
Abstract: The assembly comprises a spindle shaft (7) with spaced hydrostatic axial- radial bearings having taper surfaces (17, 18) on the shaft (7) and complementary surfaces (13, 15) in a housing (1). A piston (47) in a chamber (61) exerts axial force on the shaft (7) through a wire tension member (53). The piston (47) has portions which differ in respect of their external diameters. The shaft (7) carries a turbine blade wheel (40), and various passages and bores serve for the flow of hydraulic pressure medium to and from the various surfaces and chambers in the housing (1) and a drive block (2) and a support block (5), all enclosed in an outer tube (6). A support cylinder (43) has a transverse bore accommodating a tube piece (46) of elastic material through which the piston (47) extends diametrically, while an axial screw (44) fixes the axial position of the support cylinder (43). The axial load on the shaft (7), derived from the piston (47) is in predetermined dependence upon the pressure of medium supplied to pressure pockets (14 and 16), various throttling inserts (30), (33) being located in the respective passages (29, 32). <IMAGE>

The punches 22 are not equidistant but grouped in pairs, each pair producing characters in the known 3 x 2 dot matrix. The punches are not exactly aligned with each of the hammers 24 and some of the hammers 24 A may not be required for Braille character production. <IMAGE>
Patent GB-2020877-A (GB)
Title: Tuning Aid for Tuning Musical Instruments
IPC: G10G7/02
Filed: 1979-05-04
Abstract: A tuning aid for tuning musical instruments, particularly stringed keyboard instruments, includes an audio-to-electrical transducer (12) which may be a microphone but preferably has a capacitative sensor probe which desirably is elongate and is capable of extending across the strings of one octave of the instrument (Figs. 3,4) and an octave switch (22) and a tone switch (20) on which are manually set the nominal octave and note of the string being measured. Amplifiers (16, 24) including an AGC amplifier amplify the transducer output, and controlled band-pass filters (18, 26) are responsive to the octave and tone switches to select the pitch to be measured. A divider (32) responsive to the octave switch divides the measured frequency by a power of two. A divider (38) is connected to the output of a crystal oscillator (36) to divide by a factor dependent upon the tone switch setting. The outputs of the two dividers are compared in a discriminator (34) which compares the two frequencies. A meter (50) displays the sense and magnitude of the discriminator output so as to display in terms of cents the amount by which the frequencies differ. A sample and hold circuit (46) actuated by the AGC circuit (28) causes the display to be held for a period of ten seconds, while operation is inhibited for the first 150 milliseconds of the note sounded. <IMAGE>

Title: Improvements in and relating to the detection of particles in a gaseous medium
IPC: G01N27/00
Filed: 1979-07-04
Abstract: The presence of particles in an atmosphere e.g. oil spray or mist or particles of smoke, is detected by a quartz crystal 80 onto one of whose surfaces a sample of the atmosphere is directed so as to cause the particles to impact on the surface and to be retained thereon. The crystal is connected to an electrical circuit which is arranged to detect when the change in oscillating frequency of the crystal indicates the presence of particles. The surface of the crystal is coated with polytetrafluoroethylene which is found to help to contain particles on the surface, particularly oil drops. One or more air cleaning jets 92, 94 are provided which are automatically operated when the crystal surface becomes contaminated. The PTFE coating facilitates the removal of this contamination by the air jet(s). <IMAGE>
