Title: Improvements in Shirt Boards for Ironing Machines.
Inventor: GOOLD LEWIS WILLIAM
IPC: D06F71/20
Filed: 1918-11-27
Abstract: 134,386. Goold, L. W., (American Laundry Machinery Co.). Nov. 27, 1918. Ironing-machines, boards for; shirt clamps for ironing-apparatus.-The neck-band end of the board of a shirt-ironing machine diverges rearwardly, preferably on a curve, as shown at 24, Fig. 4, so as to secure proper shoulder folds when the shirt is buttoned after ironing. The side curved parts are tangential to the back portion of the neck.band former. The board also widens towards the tail end, as shown, so that shirts may be ironed while unbuttoned. and opened out. The invention also comprises an expansible neckband former with a clamp for the ends of the neck-band operated by the means employed for adjusting the former. The board 9, Fig. 2, is carried by a frame 14, Fig. 1, slidably mounted on a base portion 3 carried non-rotatably on a pillar 2, and the front portion 13, Fig. 7, of the neck-band former is carried by a bar 8 secured to a fixed frame extension 6. Fig. 1, of the frame 3 so as to be maintained always in correct registering position for the recess in the pressing element. The front portion 13 is mounted on pins 11, Fig. 5, so as to sink into the covering 10 of the board when pressure is applied. A heated yoke-receiving frame 16 carried by the board is formed with a slot to accommodate a transverse rod 19 engaging rear portions of the neck-band former, so that as the board is moved on the base, these rear portions move backwardly and outwardly, as shown in Fig. 5. A clamping plate 2, Fig. 7, is mounted rigidly or pivotally on a rod 29 slidably through the relatively fixed front portion 13 of the neck-band former, and is pressed lightly into engagement with the ends of the neckband bv the fingers of the operator. It is retained in this position by a pivoted locking-plate 31 mounted in a plate 33, which is moved by a sliding member 38 to secure a greater clamping pressure, when the board is moved on its base to adjust the neck-band former. The means for adjusting the former and clamp comprises a shaft 41 fitted with an operating-arm which is raised from the position shown first to increase, the clamping pressure by the action of the rod 40 and lever 39 and then to bring about the engagement of a roller 47 on an arm 46 with a stop surface 48 on the movable frame part 14, to move the board and adjust the neck-band former. A one-way lock 60 similar to the lock 31, Fig. 7, maintains the parts in the adjusted position. In the reverse movement this lock is first released, the board is then moved to collapse the former, and finally the clamp is released.

Title: A compacting device used in connection with a refuse cart
IPC: B65F3/20
Filed: 1959-06-08
Abstract: 856,401. Refuse vehicles; compacting materials. OCHSNER & CIE A.G., J. June 8, 1959 [Jan. 7, 1959], No. 19564/59. Class 78 (4). A device for compacting refuse into the body 3 of a vehicle normally repeats its working cycle continuously and without interruption; it includes a pivoted plate 26 which delivers to the body 3 refuse carried from a trough 13 by a conveying device. In the form illustrated the refuse is fed to the plate 26 by a ram 15 formed with guard plates 17 so that refuse can be charged through an opening 14 even when the ram 15 is in its forward (broken line) position. The ram 15 may however be replaced by a pivoted plate working over a part-cylindrical bottom to the trough 13, or by a lath conveyer operated through one step at each cycle. In the form illustrated the plate 26 and ram 16 are operated by hydraulic jacks 31, 21 controlled by limit switches and relay valves to produce a repeated cycle in which material is pushed from the trough 13 by the ram 16 while the plate 26 is in its retracted position, and then swept by the plate 26 into the container 3. Manually-controlled switches, or switches controlled automatically by the rise in the pressure in the jacks, may reverse the motion of the plate 26 if this is jammed by material. All the compacting apparatus is carried by a rear gate 11 carried on hinges 10 to swing clear of the body 3 when the body is tipped.

Abstract: 713,542. Burglar and like alarms. E.M.G. HANDMADE GRAMOPHONES, Ltd. Nov. 20, 1952 [Aug. 20, 1951], No. 19637/51. Class 118 (1). A burglar alarm for protecting articles in a container such as a show-case, comprises a valve oscillator mounted within the container, a switch system for switching on the oscillator if the container is broken into, and an alarm device including an element disposed.at a substantial distance (i.e., a few feet) from the oscillator and coupled thereto inductively. The oscillator mounted within the show-case comprises a valve V1 whose cathode-heater current is supplied through a switch S which closes, should the case be broken into. The coil L1 is arranged co-axially with a similar coil L2 mounted in the ceiling above the show-case. A signal picked up by the coil being amplified by valve V2, rectified by rectifier D, and the resultant uni-directional potential used to cause the normally non-conducting valve V3 to conduct, thus operating relay R itself connected to control an alarm device, e.g., a bell. The oscillator frequency chosen preferably lies between 6 kc/s and 30 kc/s. The switch S may be provided by a number of switches connected in parallel and attached to plate glass sheets mounted within the show-case so that upon movement of these sheets one at least of these switches is closed. One such plate-glass sheet may be arranged immediately beneath the upper glass panel of the case and switches mounted so that one or more close when the sheet is depressed, while another or others close when it is lifted. Similar sheets may be arranged adjacent the side panels of the case. The Specification discusses also a possible burglar alarm similar to that described above, wherein a small radio transmitter is provided within the show-case for communicating with a receiver including an alarm system. Such an arrangement does not form part of the present invention.

Abstract: A vaccine for protecting poultry against Avian Encephalomyelitis, is prepared as follows: (1) Removal and treatment of brain tissue from an infected chick within 48 hours of onset of clinical symptoms; (2) Intracerebral injection of material thus obtained into a susceptible chick; (3) Removal and treatment of brain tissue from the thus-infected chick within 48 hours of onset of clinical symptoms; (4) Inoculation of the thus-obtained material into a viable embryo in an egg from a non-immune hen; and (5) Removal and treatment of brain tissue from the thus-infected normal live embryo to give the required vaccine. Preferred susceptible chicks are one day old, and cease to be susceptible over the age of 21 days.  Embryos used must be 4 to 6 days old in order not to be killed by the injection.  Treatment of the brain tissue suitably comprises addition of diluent buffer, preferably containing streptomycin, followed by homogenisation, cellular disintegration by ultrasonics, and centrifugation, to give a clear supernatant, to which is added glycerol.  Preferably treatment by ether extraction of the final embryo brain preparation is effected before the glycerol addition of this stage.  The vaccine may be administered orally, suitably at pH7, for example through the drinking water, to chicks above the age of 10 weeks.
