[Also in Group XVII] A sack-holding shoot 1 for bagging grain has an outwardly-projecting flange 3 around its outlet 2 and a valve 9 operated by a lever 10 carrying a bracket 11 to which is pivoted a roller 12, e.g. of rubber. When the valve is closed, the mouth of a sack is arranged around the flange. Opening of the valve causes the roller to move and hold the sack against the flange. The roller may notch into a slot 4 in the flange. The valve may be a flap mounted on an axle 6 pivoted between opposite sides of the shoot and parallel to the axes 12A of the roller, but offset therefrom so that, when the valve is fully open, reaction between the roller and flange opposes any closing movement. The axle 6 may be off-set from the centre line of the flap so that, when closed, the pressure of grain on. the flap tends to keep it closed. A stop 13 may limit the opening movement. The roller may over-ride the stop to lock the flap in the closed position.

Patent GB-1464371-A (GB)
Title: Coin operated apparatus
IPC: G07F9/02
Filed: 1973-01-29
Abstract: 1464371 Coin operated apparatus R VERRILL and B M J VERRILL [trading as VERITRONICS] 29 Jan 1974 [29 Jan 1973] 4449/73 Heading G4U Coin-operated apparatus comprises a pair of parallel plates forming an electrical capacitance 4 through which a coin passes in use, means for measuring the change in capacitance caused by the coin and means for releasing a mechanism to enable it to operate if the change of capacitance falls with a predetermined range. A signal generator 2 generates a 100 Hz waveform which is applied to one plate of capacitor 4. A coin switches on the power supply by means of a micro-switch (not shown). A current amplifier 6 amplifies the square wave of current induced by the triangular voltage waveform. Rectifier 8 converts this signal to a D.C. proportioned to the capacitance 4 at its output. Output from the rectifier is fed to "upper limit" level detector 10 and "lower level limit" level detector 12. If these give a satisfactory signal, AND gate 14 is activated to transmit a signal to 10 ms. delay device 16 which gives an output only if the capacitance remains in the limits for 10 ms. This output is fed to a monostable 18 which gives a delay of 100 ms. when triggered. During the delay the circuitry is primed by causing diodes D1 and D2 to conduct and at the same time applying a fixed voltage to D1. At the end of the delay switch 20 is operated, which stays on for 30 ms. allowing a controlled amount of charge to flow into a 1 ÁF. timing capacitor 22 via diode D1. Thus each time a coin is detected the voltage on the capacitor is raised. A low frequency square wave oscillator 24 drives a 30 Ás. switch 26 which removes a controlled amount of charge from the timing capacitor once every 1À5 seconds. A meter 30 gives an indication of time left. Zero level detector 32 gives an output which switches off equipment such as tennis post solenoids at the end of the timed period. A 10 ms. delay 34 indicates an object has been present in the coin shoot for too long and operates a 60 s. switch 36 to discharge timing capacitor 22 and hold it "off" for one minute. The apparatus may be adapted to take coins of different denominations. Another application of the apparatus, apart from coin operated games, is in a parking meter.

Abstract: 413,410. Inserting rivets &c. PARNALL, G. G., and CLARKE, H. V., Coliseum Works, Park Row, Bristol. Feb. 14, 1933, No. 4468. [Class 61 (iii).] Split ferrules are inserted as distance pieces in tubular structures by means of a tool having two enlarged portions connected by a reduced portion onto which the ferrule is passed, the tool is partially inserted through the rivet holes to locate the ferrule in the structure and a bolt or rivet, secured to the end of the tool is driven through the ferrule with the tool which is afterwards removed. As shown a split spring ferrule 11 is passed over the conical end 12<a> of a drift 12 on to a cylindrical portion 12<d> of such length as to accommodate the longest ferrule to be used. The other end of the drift is provided with a similar conical portion 12<c> and with a spigot 12<e> or screwed recess to take a hollow rivet 10 or a screwed bolt. The outside diameters of the cylindrical portions of the drift and ferrule are slightly less than the diameter of the hole bored through the plates 8 and tubular structure 9 so that by inserting the drift through the hole and canting it as shown in Fig. 6, the ferrule may be expanded and the rivet 10 driven through the ferrule.

Divided out of 427,471. [Class 80 (ii)] [See also Group XXXI] In gear-shifting mechanism suitable for vehicles, selection and operation are effected by sliding and rocking, respectively, a rock shaft M, Fig. 2, and these movements are brought about by rocking and sliding, respectively, a rack bar Q<1> which engages between lateral flanges Q<2> the teeth of a sector Q fast on the rock shaft M. A cover plate N<1> for the housing A of the change-speed gearing supports a bearing N for the rock shaft M and also a mounting N<2>, Fig. 6, for the rack bar Q<1> holding the bar and segment in gear relation. The rack bar Q<1> is connected by a flexible circuitous shaft R to the shank T<1>, Fig. 4, of a control handle T near the cowl S. Selection of the gears in the housing A is thus effected by turning the handle T, and changing of the gears by pushing or pulling the handle T towards or from the cowl S. The means by which selection is effected by the arrangement shown in Fig. 2 forms the subject-matter of Specification 427,471. A rightward selective movement of the rock-shaft M against a spring U can be effected only when a notch V<2>, Fig. 6, in a plate V<1> carried by the shaft M registers with a fixed stop disc V. Specification 427,470 is referred to in which the change-speed gearing is used in series with and in front of speed-responsive automatically-variable gearing.

Title: Dehydrating fluorochloromethanes by distillation
IPC: C07C17/38
Filed: 1951-02-26
Abstract: Moist difluorodichloromethane or moist mono-fluorotrichloromethane is dehydrated by distilling the moist compounds in a fractionating column at a gauge pressure in the range of 35 to 160 pounds per square inch in the case of the difluoro-compound or of 0 to 25 p.s.i. in the case of the monofluro-compound, condensing the vapours and allowing the condensate to separate into an upper aqueous layer and a lower non-aqueous layer, returning the non-aqueous layer to the column as reflux, and withdrawing the dried fluorochloromethane from the boiler of the column.  In order to prevent droplets of water passing into the lower liquid layer a filter of wire wool, contained in a metal wire basket, is disposed beneath the liquid interface. Difluorodichloromethane containing 140 p.p.m. of water was charged into the boiler of a packed fractionating column (equivalent to 12 theoretical plates), and heated at 35 DEG C. under a pressure of 110 p.s.i.g.  The vapours from the top of the column were condensed, and the condensate was passed to a separator containing a filter of wire wool.  The water layer was removed from the system, and the CF2 Cl2 layer was returned to the column as reflux.  When the water content of the material in the boiler was less than 10 p.p.m., continuous withdrawal of the dried product therefrom was commenced, and CF2 Cl2 vapour containing 0.2 per cent. water was introduced continuously into the condenser at such a rate as to maintain steady the level of the liquid in the boiler.
