Title: Cooling brakes
IPC: F16D65/853
Filed: 1980-12-04
Abstract: A vehicle brake cooling means 5-9 for a multiple-disc brake 1 includes a valve 5 for admitting a flow of coolant to the brake 1 and a valve actuating means 9 commanded by the accelerator control 15 of the vehicle. The valve 5 may be actuated by a solenoid 11 controlled by a switch 12 mechanically coupled to the accelerator control, the switch being closed by release of the accelerator control 15, to cause flooding of the brake prior to its application. The cooling means is particularly suitable for a heavy vehicle having conventional foot operated accelerator and brake controls where the switch 12 may be a microswitch interjacent the accelerator pedal 17 and tread 18, or a hand operated accelerator control may have a microswitch. It is also envisaged that the valve actuating means be hydraulically or mechanically controlled. <IMAGE>

Title: Fluidized bed combustors
IPC: F23C10/20
Filed: 1981-03-11
Abstract: In a fluidized bed, e.g. a combustor, in which a perforated plate (20) within a housing supports a bed of particulate material, in order to protect the plate from the high temperatures generated in the bed (18), a plurality of hollow, elongated members (40) extend upwards, normally perpendicular to the plate (20) and respectively register with the perforations in the plate (20). Each elongated member (40) has an inlet at one end for receiving air and an outlet at its other end for discharging such air in an upward direction. The air discharging from the outlets fluidizes the particulate material above the outlets, and the lengths of the elongated members (40) are such that the plate (20) is insulated from the high temperatures occurring in the bed (18). <IMAGE>

Title: Stabilizers for halogenated resins
IPC: C08K5/58
Filed: 1981-04-02
Abstract: Compositions for heat stabilizing halogen-containing resins are a mixture of a tin tetrakis(mercaptide) and a sulfur-containing organotin compound, and optionally a third and/or fourth component, namely an alkali or alkaline-earth metal salt of a mercaptan or mercapto acid and/or an overbased complex of an alkali or alkaline-earth metal base.

Title: Security identification system using pulse code modulation
Inventor: BAKER DONALD G
IPC: H04M1/57
Filed: 1981-09-03
Abstract: A security identification system for telephone, teleprinter, computer, and similar communication applications comprises a plurality of transmitter station identification units, one for each transmitter station and each including means for generating a pulse code modulated identification signal, unique to the transmitter station, that comprises a repeating sequence of uncoded signal segments each including N pulse intervals of given duration alternating with coded signal segments each including M pulse intervals of like duration, coding being effected by the presence or absence of pulses in the coded signal segment intervals. Each pulse is transmitted as a burst of cycles of a carrier signal preferably having a carrier frequency above 3 Khz. The system further comprises a receiver identification unit at a receiver station, including a demodulator, identification control means, and a visual display; the control means counts the pulse intervals in a demodulated uncoded segment of the identification signal to aid in identifying the beginning of each coded segment and decodes the coded segments, on a redundant basis, to actuate the display and afford a visual identification of the transmitter station.

IPC: G09B9/04
Filed: 1983-05-06
Abstract: Vehicle steering simulation apparatus comprises a pivotable bellcrank 10 for coupling to a steering column, and a lever 2 pivoted at a pivot point 4 and acting on the bellcrank through a linkage 6. A tensator spring 42 acts on the lever to provide tension in the linkage against which the bellcrank must be rotated.

Pins 24 and 26 on the bellcrank co-operate with slots 28 and 30 formed in the link bars 12 and 14. The distance at which the tensator spring 42 acts from the lever pivot 4 may be varied so that the tension in the linkage 6 may be changed, to simulate different steering conditions. In another embodiment described a variable force acts at a fixed distance from the lever pivot 4. <IMAGE>

Title: Fuel injection pumping apparatus
Inventor: LEMON DAVID SYDNEY
IPC: F02D1/00
Filed: 1983-09-16
Abstract: A fuel injection pumping apparatus includes a high pressure pump and a low pressure pump contained in a housing. A fluid pressure operable piston is subjected to the outlet pressure of the low pressure pump, the pressure varying with the speed of operation. The piston is also subjected to the pressure in the housing. In order to compensate for fuel viscosity changes, which alter the outlet pressure a pressurizing means 40, Figure 1, (not shown) is utilized to control the pressure in the housing. The pressurizing means includes a head 50 located in a bore in a sleeve element 47 and defining an annulus 51 through which fuel can escape from the housing. The sleeve element has a port 52 which defines an orifice through which fuel can escape. Two parallel flow paths are formed which can be dimensioned so that the net pressure acting on the piston can be substantially independent of the viscosity of the fuel. <IMAGE>
