Title: Intra-venous infusion device
IPC: A61M39/28
Filed: 1970-10-21
Abstract: 1335395 Intravenous infusion device BIOMEDICAL SCIENCES Inc 21 Oct 1970 49996/70 Heading A5R  An intravenous infusion device comprises a container 10, whose interior is divided by a diaphragm 30 so that the diaphragm selectively abuts the wall 18 of the container when fluid 68 is introduced through an inlet 42 and then the opposite wall 16 when pressurised gas is introduced from a second container 12, whereby the fluid 68 is ejected from an outlet 46 at a steady rate into a flexible tube 58 from which it passes to a hypodermic needle. The tube 58 is attached to the container 10 by means of a coupling 60 externally threaded to engage the discharge opening 46, and having a spiked end 60 to perforate a seal 50 over the spring 46 when the coupling is engaged. The gas container 12 has an externally threaded neck 52 closed by a seal 54, which engages an internally threaded socket 34, on the container so that a protruding inlet 40 pierces the seal 54 when the gas container is attached and allows the gas to pass into container 10. The flow rate of the fluid to the hypodermic needle is regulated by a combined flow regulator and flow rate testing apparatus, which comprises a pair of spaced flow control members 110 and 120 with valves 92 and 94 for regulating the flow of fluid through compressible resilient tube 58 which passes through the control members. The tubes can be constricted by a clamp 84. Each control member comprises a tubular housing 80, 82 with a bore hole 106 intersecting a bore 104 which supports the tube such that a valve 94 which is rotatably received in the bore by means of a bead 98 and thread 96 connection may constrict the tube and thus adjust the fluid flow rate. A scale and pointer 82a and 100 are provided on the housing and valve respectively to indicate the position of the valve and thus the fluid flow rate. The control members are integrally connected by a member 78, which supports the tube. The flow rate can be tested by first emptying the conduit by compressing it between the clamp 84 and support member 78 and then cutting off the flow through the control member 92, and measuring the time taken for the conduit to fill up again to its known volume. A section 102 of the conduit downstream of the controller 92 has a reduced wall thickness which enables it to indicate by pulsation any undue fluctuation of the flow rate.

Abstract: 1,247,165. Rail vehicle hoppers. ROTAQUE (PTY) Ltd. 23 Oct., 1968, No. 50272/68. Heading B7L. A side discharge rail vehicle hopper comprises a wheeled chassis 10 having pivoted thereto at 24 the hopper bottom 16 and pivoted to the bottom at 38 a side structure 30, there being located on the bottom 16 angle members 42 and 44 which co-operate with members 18, 22 on the chassis to locate the components in the load-carrying condition of the hopper and also longitudinal pegs 48 located behind lugs 46 on chassis end plates 20, there being fixed to opposing sides of the structure 30 wheels 50, 56 which run on rails 60, 58, these rails being raised at a discharge station so that the hopper there assumes its discharge condition, Fig. 3. The bottom 16 is formed with side walls 62 thereby providing it with a shoot-like configuration. In a modification, Fig. 7, the hopper is discharged by lifting the side 49 of structure 30 using a rod 77. A roller 48 on the structure 30 guides and limits the structure by engaging a slot 70 in an extension 62À1 of bottom side walls 62. Tilting of the bottom is caused by a further roller 72 on structure 30 moving in a slot 74 located in an extension of end plate 20. In a further embodiment, Fig. 9, the structure 30 is raised by means of a ram 86 engaging an abutment 80À1, there being attached to the ram a cable 88 which passes over pulleys and is connected at its opposite end to a point 80 on structure 30. The arrangement is such that the point 80 is raised a little before abutment 80À1.

Title: Hydrostatic assist drive for vehicles
IPC: B60K17/10
Filed: 1974-11-21
Abstract: 1487226 Hydrostatic transmissions CLARK EQUIPMENT CO 21 Nov 1974 [21 Nov 1973] 50580/74 Heading F2W [Also in Division B7] In a vehicle having front and rear wheels 10, 12 respectively, a main drive train drives at least one wheel at one end of the vehicle and an auxiliary drive comprising a hydrostatic transmission with pump 16 supplying at least one hydraulic motor 14 can be selected to drive at least one wheel at the other end, the speed of the auxiliary hydrostatic transmission being controlled through an adjustable flow divider so that the wheel(s) driven thereby rotate to provide the same vehicle speed as provided by the wheels driven by the main drive train. In the embodiment shown in Fig. 1 the wheels 10 are driven by a mechanical transmission and the pump 16 can supply motors 14 via side 94 of a flow divider 90 and a reversing valve 96. The flow divider 90 is controlled to provide the desired speed at wheels 12 by a pump 122 which creates a pressure in a servo 102 from lines 138, 140, the pump 122 being engine driven to provide a speed proportional pressure. A valve 126 is opened by a solenoid to allow pressure in lines 138, 140 to actuate servo 102 to allow divider 90 to supply fluid to the motors, reversing valve 96 simultaneously being solenoid operated to allow forward or reverse rotation of the motors. A valve 98 allows a proportion of the fluid in the working circuit to flow to sump 42 through a constant flow-rate valve 115 when open, valve 98 being closed when motors 14 are driven. Alternatively control of flow divider 90 can be purely electrical, a signal responsive to the speed of a wheel 10, or a signal from a speedometer, operating an electrical servo. With the mechanical transmission shown the auxiliary drive may only be operated with the transmission in low gear. The transmission of Fig. 1 is shown in a fork-lift truck in which valves 32 and 34 are operated by levers 36, 38 respectively to supply fluid to lift or tilt servos 24, 30 respectively, the pressure fluid being supplied from the side 92 of the flow divider 90. The auxiliary hydrostatic drive may be automatically put into neutral (the condition shown) on operation of valve 32 or 34 to divert the entire output of pump 16 to the left or tilt services. Instead of a fork-lift truck, the auxiliary drive may be in an earth-moving scraper machine, a towing tractor, a chemical sprayer or an agricultural vehicle. The main propulsion can be electric, instead of mechanical or hydrostatic. The wheels 12 can be steerable. Depression of a clutch pedal may disconnect the auxiliary drive.

[Class 27] [Also in Group XXIV] Means for testing time-controlled mechanism such as a switch or valve in a two-part tariff prepayment meter comprises an alternative gear train which can be inserted for testing purposes between the clock device and the mechanism which it drives so that a cycle of operations may be carried out in considerably less than normal time and the time taken for the test correspondingly reduced. In the construction shown a spindle 3 driven at a constant speed by a synchronous electric motor or other clock device drives a spindle 2 of the meter mechanism through a gear train 10, 9. 12a and reducing gearing 12b, 13a - 13b, 14, the double gears 12a, 12b and 13a, 13b being loose on their respective shafts, and the gear 9 being an idler. When the meter mechanism is to be tested the idler shaft 1 is moved axially against the pressure of a spring 6 by means of a rotary cam 7 until gear 9 disengages from 12a and meshes with a gear 11 fixed on spindle 2, gear 13b being at the same time disengaged from gear 14. The spindle 3 now drives the spindle 2 directly through the idler 9, and the reduction gear is cut out. If this reduction gear has a ratio of 24:1 a test may be carried out in one hour which would otherwise take twenty-four. When the shaft 1 is in the testing position it may project sufficiently to prevent a cover being replaced, or other means may be provided to prevent the shaft being left in the testing position.
