Abstract: 1,154,865. Calculating apparatus. A. HEYER. 26 Oct., 1966 [28 Oct., 1965], No. 48123/66. Heading G4B. Calculating apparatus comprises a rotary totalizer 3 carrying spaced shafts 9 arranged in a circular fashion and supporting gears 6a-6i at different levels and five superimposed sets of rods 4a-4e adapted to be projected by means 5 to engage corresponding gears on rotation of the totalizer and step them a corresponding amount. A cranked member 5a-5e co-operates with apertures in the rods 4a-4e, respectively, whereby a selected number of rods in each row may be projected on sliding the associated cranked member to the right as seen in Fig. 2. Each cranked member bears the numerals 0-9 on its upper surface which may be viewed through the top cover of the apparatus to indicate the number of rods projected. Actuation of a bar 13 returns the cranked members 5a-5e and rods 4a-4e to their initial positions. The gears 6a-6h are associated with transfer pawls 7a-7h driving the next " higher " gear 6b-6i through gears 8a-8i. The shafts 9 carry numbered discs visible through the top cover. The rotary totalizer is supported on an annular member (22) restrained against rotation by pins (39) engaging slotted legs (37), each leg cooperating with a cam surface (33) on a member (23), angularly adjustable to move the rotary totalizer axially and select the denomination, Fig. 6 (not shown). The member 23 is movable by an arm 31 into one of four positions determined by a click-stop mechanism, Fig. 4. The rotary totalizer supports four numbered wheels 50 fixed to vertical shafts driven by gears 21a- 21d disposed at different levels. A stationary cam 52 co-operates with one of the gears 21a- 21d, according to the axial position of the rotary totalizer, to step the associated numbered wheel on each revolution of the rotary totalizer. The latter rotates about a central shaft which may be lifted to bring a gear thereon into engagement with mutilated gears on the shafts of gears 21a-21d and rotated to zeroize the numbered wheels. Operation of a lever 30 lifts a gear into engagement with gears 11a-11i on shafts 9 so that operation of the rotary totalizer resets the number discs 29a-29i to zero.

Abstract: 1449612 Hot water supply; central heating G APPLEGATE 5 Nov 1973 [19 Oct 1972] 48175/72 Headings F4A and F4U A hot fluid supply system comprises a first circuit 1 with a pump 2 for circulating fluid therein, and a plurality of secondary circuits 4, each having a pump 5 and a heater 6, and fluid mixing means at the connection of each secondary loop to the primary loop, each pump 5 in operation causing fluid from the primary loop to flow through the associated heater 6 and return to the primary loop. Each secondary circuit 4 is connected by pipe couplings 13, 14 to annular chamber 11 of a header 3, the fluid in the first circuit flowing in through a pipe 9 in the chamber, which has upstream apertures communicating with the chamber, and out through a pipe 10 surrounding the pipe 9. Alternatively all the secondary circuits may be connected to a single header, Fig. 3 (not shown). The secondary circuits may be connected in various combinations of series and parallel, Figs. 5a-d (not shown), and a line (59) from the pump 2 may by-pass the secondary circuits and rejoin the circuit 1 at a three-way valve (58), Fig. 6 (not shown). The pump and a gas valve of the heater of each secondary circuit are connected in parallel and the voltage applied in the case of one circuit is controlled in dependence on sensed outside temperatures, while the other circuits are either on or off, so that the number of secondary circuits in operation is determined by the sensed temperature. A control circuit is described, Fig. 4 (not shown). The first circuit 1 may supply control heating radiators, and a further circuit branching off the secondary circuits may serve for indirect heating of a water supply, Fig. 7 (not shown).

Title: Method for separating isotopes by means of lasers

Filed: 1975-11-28
Abstract: 1524538 Producing selective excitation by means of electromagnetic radiation URANIT URAN-ISOTOPENTRENNUNGS-GmbH 28 Nov 1975 [11 Dec 1974] 48956/75 Heading G6P In a method of isotope separation by isotopically selective laser excitation, prior to irradiation the mixture to be separated is passed through a nozzle to effect cooling by adiabatic expansion. This has the effect of "freezing" certain rotational/vibrational degrees of freedom and ensures high occupancy of lower energy states. As described, the mixture (which may be admixed with a buffer gas such as helium or hydrogen) leaves a high pressure chamber 1 and passes into a low pressure chamber 3 in the form of a supersonic, cooled gaseous stream 4 issuing from the. expansion nozzle 2. Baffles 15 trim the stream's edges to reduce the distribution of molecular velocities in the stream 4. Radiation 16 from a laser 5 (whose lasing medium may be HF, HCl, CO, COS and CS 2 ) strikes the stream 4 at an angle #. By giving the stream 4 and laser beam 16 directional components along a common axis, the Doppler effect gives an enhanced selectivity to excitation. If desired excitation can occur in the presence of a chemical reactant (e.g. NH 3 , HCl or HBr) which can be introduced into the low pressure chamber 3 as a second stream 8. Reaction and unconverted products are extracted-using a fractional condensation system 9-at outlets 11-14. Alternatively, further irradiation can be applied to dissociate or ionize the excited molecules; separation can then be performed by electromagnetic deflection.
